               EPA CHEMICAL PROFILES:   INTRODUCTORY INFORMATION

                                  BACKGROUND
     The U.S. Environmental Protection Agency has developed & set of chemical
profile reference documents for use in dealing with Section 302 of Title III
of the Superfund Amendments and Reauthorization Act (SARA).  These EPA
profiles contain a summary of publicly available documented information for
chemicals on the EPA list of extremely hazardous substances listed in the
Federal Register, Vol. 52, No. 77, April 22, 1987.

     The profiles were originally developed in 1985 for the 402 chemicals
then called "acutely toxic chemicals" under the Chemical Emergency
Preparedness Program.  When the list went into law as the list of extremely
hazardous substances, four additional chemicals were included.  Forty of the
406 chemicals were subsequently deleted from the list.  Profiles are provided
for the 366 chemicals listed in February, 1988, as extremely hazardous
substances.  Other chemicals may be added or deleted in the future.  The  .
profile format was revised and the data were reviewed, augmented, and revised
as appropriate in 1987.   The profiles have been reviewed for accuracy and
completeness.  However,  an exhaustive literature search was not performed for
each chemical, and a review of original citations has not been made.  

     A profile is provided for each chemical on the list of extremely
hazardous substances.  Profiles are presented in ascending order of Chemical
Abstract Service (CAS) registry numbers.  One chemical (generic name:
organorhodium complex) is identified by a premanufacture review notice (PMN)
number and appears first.

     The CAS number was used to search the automated Toxicology Data Base
(TDB) or Hazardous Substance Data Bank (HSDB) from the National Library of
Medicine (NLM).   If available, TDB/HSDB files were retrieved.  Approximately
65 percent of the chemicals were listed in the TDB/HSDB files.  For these
chemicals,  the TDB/HSDB files provided the main source of information for the
profiles.  All data obtained from the TDB/HSDB were indicated by an asterisk
(*) followed by a reference to the TDB/HSDB citation, (e.g., (*Merck 1976)).
For those chemicals without a TDB/HSDB file, a limited number of standard
reference materials was searched.  Such references are cited by author, year,
and page number.  A master list of references, including the secondary
references cited in TDB/HSDB, has been prepared and may be found in the
Reference Section of this document.  The abbreviations used in the profiles
have been defined in a master list and may be found in the Abbreviation
Section.  Medical terms not commonly used have been included in a Glossary
Section.  Dorland's Medical Dictionary (1974) was used to provide most of the
definitions in the Glossary.

     If information was not available for a specific compound but the
chemical could be categorized, then general information about the chemical
category was included.  Such information is indicated, for example, by the
notation "Non-Specific -- Organophosphorus Pesticide" or "Non-Specific --
Poisonous Solid, n.o.s.".

                      DISCUSSION OF SECTIONS  OF PROFILES
     Each profile includes chemical identity information and eight sections
containing information on regulations, properties, hazards, uses, and
precautions.  Comments on the elements of the profiles are presented below.

     Chemical Identity.  The name given on the profile is the name used on
the list of extremely hazardous substances (Section 302 of SARA Title III)
and is one of the most common names.

     CAS Registry Number.  The number is identical to the number listed in
the National Institute of Occupational Safety and Health (NIOSH) Registry of
Toxic Effects of Chemical Substances (RTECS).

     Synonyms.   Synonyms from TDB/HSDB files are listed without citation.
Synonyms from NIOSH/RTECS (1983) or the Structure and Nomenclature Search
System (SANSS)  (1983) ,  or other sources are referenced.  The 9th Collective
Index (CI) name from the SANSS 1983 database was added to each profile when
the 9th CI name was different from the 8th CI name.

     Chemical Formula and Molecular Weight.  Data from TDB/HSDB or
NIOSH/RTECS (1983) are not cited.  Formulas or molecular weights found in
other sources are cited.

     Section I -- Regulatory Information.  The toxicity value that placed the
chemicals on the list has been included in this section.  These toxicity data
were obtained from a screen of the NIOSH/RTECS on-line computer file and are
also cited with an asterisk (*) (e.g., *NIOSH/RTECS 1985).  Toxicity data
were not included for chemicals listed on the basis of high production volume
and known toxicity ("Other" chemicals).

     Also included are Threshold Planning Quantities (TPQs) and Reportable
Quantities (RQs), as listed in the Final Rule (Federal Register, Volume 52,
Number 77, April 22, 1987).

     An indication of whether the chemical is listed under Section 313 of
Title III of SARA is included; if the chemical falls into a chemical category
listed in Section 313, the category is given.

     Section II -- Physical/Chemical Characteristics.  Physical state (solid,
liquid, or gas) at ambient conditions is listed, as given in the Interim
Final Rule (Federal Register, Vol. 51, No. 221, November 17, 1986); no
reference is cited on the profiles.  Other properties are included with
references.

     Section III -- Health Hazard Data.  Generally, only human data are
reported in the Health Hazard Data section.  The following exposure limits
are included, if available:

         Occupational Safety and Health Administration  (OSHA)
          Permissible Exposure Limits (PELs);

         American Council of Governmental Industrial Hygienists  (ACGIH)
          Threshold Limit J/alues  (TLVs); and

-------
                                     -3-
         Immediately Dangerous to Life and Health (IDLH) levels
          developed by N10SH.

     The following limits may be listed under Other Limits Recommended, if
available:

         NIOSH recommendations;
         EEGLs (emergency exposure guidance levels);
         SPEGLs (short-term public emergency guidance levels);
         Human carcinogens or suspect carcinogens listed by the ACGIH;
         OSHA carcinogens;  and
         NIOSH potential occupational carcinogens.

EEGLs and SPEGLs, developed by the National Research Council of the National
Academy of Sciences, are discussed in more detail in Appendix D of the
Technical Guidance for Hazards Analysis (EPA 1987).  An EEGL is defined as an
acceptable concentration for unpredicted, single, short-term emergency
exposure of a defined occupational group (EEGLs have been developed for
military personnel).  A SPEGL is defined as an acceptable concentration for
unpredicted, single, short-term, exposure of the general public in
emergencies.

     Information on the route of exposure and health hazards often was not
available or only partially available for specific chemicals.  Health hazard
data often were not found specific to dose, route of entry or exposure type
(acute, delayed, or chronic).  Generic information on the chemical category
was provided, wherever possible, in the absence of information on the
specific chemical.

     Section IV -- Fire and Explosion Hazard Data.  In the absence of
chemical-specific information, generic information is provided whenever the
chemical could be categorized.  National Fire Protection Association (NFPA)
flammability ratings from the NFPA Fire Protection Guide on Hazardous
Materials are included if available.

     Section V --  Reactivity Data.  In the absence of chemical-specific
information, generic information is provided whenever the chemical could be
categorized.

     Section VI -- Use Information.  This section includes uses of the
chemical as reported in HSDB or other sources.

     Section VII -- Precautions for Safe Handling and Use.  Chemical-
specific information often was not available; therefore, generic information
for the chemical category often is presented.

     Section VIII -- Protective Equipment for Emergency Situations.  This
section contains recommendations for the type of personal protective
equipment to be used.  See page 5 for a detailed discussion of personal
protective equipment.

     Section IX -- Emergency Treatment Information.  This section contains
information on signs and symptoms of poisoning and emergency treatment
information for first responders.  Emergency planners may be especially

-------
                                     -4-

interested in references to medical equipment and supplies that could be
useful in case of the accidental release of the extremely hazardous
substance.

     Approximately 120 of the revised chemical profiles contain complete
revisions of the emergency treatment information section and have been
retitled the Emergency First Aid Treatment Guide (EFATG).   This new section
has been reformatted and contains more detailed guidance for emergency
treatment based on information obtained from the Rocky Mountain Poison
Center's proprietary data base, Poisindex.  The order of completion of
EFATG's is being carried out by priority based on considerations of toxicity,
production volume, and availability of specific emergency treatment
information.  Revisions of the emergency treatment information sections for
the remaining profiles is underway and will be published as soon as they are
completed.  In the meantime, these profiles contain the emergency treatment
information that was originally published in 1986.

     Because the emergency treatment information is designed for use by first
responders, references to signs and symptoms of exposure as well as
procedural guidance avoid the use of highly technical medical language.
Signs and symptoms are not distinguished by route of exposure.  Emergency
treatment procedures, on the other hand, are presented according to route of
exposure, with emphasis on the inhalation and dermal routes.  References to
invasive treatments are limited, since the emergency treatment information is
directed to first responders rather than medical practitioners.  First
responders must be aware of particular state and local regulations which
govern the extent of invasive treatment that they may perform.

     The Agency for Toxic substances and Disease Registry (ATSDR) has
provided general review of the EFATf-'s for format and content.

     Comments.  This section is provided, in some cases, to list the sources
that were checked for information in cases of chemicals for which few data
were available.  In general, this section pertains to chemicals without
TDB/HSDB files.

     Not Found.  This statement on the profile can mean that:

         The value or information was not found in the references used;

         The value or information probably does not exist for this
          chemical; or

         The value is meaningless or not applicable for this chemical.

                        PERSONAL PROTECTIVE EQUIPMENT
     Personal protective equipment (PPE) for emergency response situations
involving extremely hazardous substances must be selected carefully and used
properly.  The PPE should protect the respiratory system, skin, eyes, face,
hands, feet and body from chemical, physical and biological hazards that may
be encountered during an emergency response action.  Selection of the proper
personal protective equipment must consider the specific hazards responders
are likely to encounter at a particular site.  Selection is a complex task
and should be performed only by individuals with proper training and
experience.

     Regulatory Requirements and Other Standards.  Selection, use, training
and programs for PPE for emergency response situations may be covered by
regulations and standards under the Occupational Safety and Health
Administration (OSHA) 29 CFR 1910, Environmental Protection Agency (EPA)
regulations and recommendations, Department of Transportation (DOT)
regulations, or National Fire Protection Association (NFPA) standards.

     Personal Protective Equipment for Emergencies.  During an emergency
involving extremely hazardous substances, a wide variety of conditions may
occur.  Therefore, response personnel should wear maximum protection
initially until actual conditions at the site are evaluated.  Maximum
protection is designed to provide the highest available level of respiratory,
skin and eye protection.  Recommended equipment consists of a positive
pressure, pressure-demand full facepiece self-contained breathing apparatus
(SCBA) or full facepiece supplied air respirator with escape SCBA and a
fully-encapsulating chemical-resistant suit.  In addition, other equipment
such as inner chemical-resistant gloves, chemical-resistant safety
boots/shoes, and two-way radio communications, a cooling unit, coveralls,
long cotton underwear, hard hat, disposable gloves and boot covers may be
worn as needed.

     Figure 1 gives an example of a worker outfitted in a fully-
encapsulating suit with respiratory protection.  Note that if the fully-
encapsulating suit does not have integral gloves and boots, then glove/suit
and boot/suit joints should be sealed with tape.

     Respiratory Protection.  Positive pressure self-contained breathing
apparatus (SCBA) should be worn by employees engaged in emergency response
and exposed to hazardous substances until it is determined that a decreased
level of respiratory protection will not result in hazardous exposures to
employees (See OSHA 29 CFR 1910.120 Hazardous Waste Operations and Emergency
Response).

     Chemical Protective Clothing and Equipment.  The selection of chemical
protective clothing is a complex process and many factors must be considered
such as:  the nature of the hazard; the potential route of exposure;  the
tasks to be accomplished; and the performance of the protective equipment
materials in forming a barrier to the chemical substances encountered at a
site.  No protective equipment material protects against all chemicals and
combinations of chemicals.  In many cases, the chemical substance may
permeate or break through the protective equipment;material, exposing the
wearer to the chemical.  It is important to note that the information

presented for an individual chemical may not be applicable when that chemical
is present in a mixture, as the ability of a chemical in a mixture to
permeate a material may differ from that of the pure chemical.  Further
studies are needed to evaluate the characteristics of mixtures of chemicals
in relation to materials for personal protective equipment.

     The chemical profiles give general information on the chemical
resistance of various suit materials to provide a basis for a decision on
whether suit materials are adequate.  This information is available for about
half of the chemicals on the list of extremely hazardous substances.  The
chemical resistance information for each suit material is indicated on the
profiles by the entries shown below.  Explanations of their meanings follow
the entries.

         Excellent Resistance/Many Data means there is quantitative
          information indicating that the material demonstrates
          excellent chemical resistance to the substance.

         Good Resistance/Limited Data means there is quantitative
          information indicating that the material demonstrates good
          chemical resistance to the substance.

         Poor Resistance/Many Data means there is quantitative
          information indicating that the material demonstrates poor
          chemical resistance to the substance.

         Poor Resistance/Limited Data means there is quantitative
          information indicating that the material demonstrates poor
          chemical resistance to the substance.

         Good Resistance/Limited Data* means there is qualitative
          information indicating that the material demonstrates good
          chemical resistance to the substance.  Most of this
          information is based on qualitative ratings from glove
          material manufacturers and may or may not be based on actual
          testing.  This entry on the profile is intended to provide
          general guidance in selecting chemical protective clothing.

         Poor Resistance/Limited Data* means there is qualitative
          information indicating that the material demonstrates poor
          chemical resistance to the substance.  Most of this
          information is based on qualitative ratings from glove
          material manufacturers and may or may not be based on actual
          testing.  This entry on the profile is intended to provide
          general guidance in selecting chemical protective clothing.

         Good Resistance/Limited Data** means there is qualitative or
          quantitative information indicating that the material
          demonstrates good chemical resistance based on the generic
          family of chemicals to which the substance belongs.  Most of
          this information is not based on testing done on the substance
          itself.  This entry on the profile is intended to provide
          general guidance to the initial selection of chemical
          protective clothing and to narrow the scope of alternative
          materials.

-------
                                     -8-
         Poor Resistance/Limited Data** means there is qualitative or
          quantitative information indicating that the material
          demonstrates poor chemical resistance based on the generic
          family of chemicals to which the substance belongs.  Most of
          this information is not based on testing done on the substance
          itself.  This entry on the profile is intended to provide
          general guidance to the initial selection of chemical
          protective clothing and to narrow the scope of alternative
          materials.

     Remember that this information provides guidance only and is not a
guarantee that the suit will protect an individual from prolonged or repeated
exposure and may not provide adequate protection for mixtures of chemicals.
Consult reference 1 for more information.  Also, be sure to consult with
facility representatives for additional information.  Other considerations
include durability and flexibility of the chemical protective clothing, and
heat stress.  Table 1 lists the fully-encapsulating suit materials available
on the market as of February, 1987.  (See non-mandatory Appendix B of OSHA 29
CFR 1910.120 for more information).

     Special Use Considerations.  Fire, heat, explosion and radiation require
special-protective equipment.  It is important to provide protection from
these hazards in addition to chemical hazards.  Section IV of the profiles
entitled Fire and Explosion Hazard Data should be consulted for further
information.  (See OSHA 29 CFR 1910.156, DOT and NFPA standards and
recommendations for more information.)

     Decontamination.  Decontamination of personal protective equipment
should be tailored to the specific conditions at the site and will vary
accordingly.  (See non-mandatory Appendix D of OSHA 29 CFR 1910.120 for
additional information).

                                 FORMALDEHYDE

Signs and Symptoms of Acute Formaldehyde Exposure:

Acute exposure to formaldehyde may result in irritation or burns to the skin,
eyes, and mucous membranes; lacrimation (tearing); nausea; vomiting (may be
bloody); abdominal  pain; and diarrhea.  Difficulty in breathing, cough,
pneumonia, and  pulmonary edema may occur.  Sensitized people may experience
asthmatic reactions, even when  exposed briefly.  Hypotension (low blood
pressure) and hypothermia (reduced body temperature) may precede cardiovascular
collapse.  Lethargy, dizziness, convulsions, and coma may be noted.  Nephritis
(inflammation of the kidneys),  hematuria (bloody urine), and liver toxicity
have been reported.


Emergency Life-Support Procedures:

Acute exposure to formaldehyde may require decontamination and life support for
the victims.  Emergency personnel should wear protective clothing appropriate
to the type and degree of contamination. Air-purifying or supplied-air
respiratory equipment should also be worn, as necessary.  Rescue vehicles
should carry supplies such as plastic sheeting and disposable plastic bags to
assist in preventing spread of contamination.


Inhalation Exposure:

1.   Move victims to fresh air.   Emergency personnel should avoid self-exposure
     to formaldehyde.

2.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma. If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration.  If breathing is labored, administer oxygen or
     other respiratory support.

3.   Obtain authorization and/or further instructions from the local hospital
     for administration of  an antidote or performance of other invasive
     procedures.

4.   Transport to a health care facility.
Dermal/Eye Exposure:

1.  Remove victims from exposure. Emergency personnel should avoid self-
     exposure to formaldehyde.

2.  Evaluate vital signs including pulse and respiratory rate, and  note any
     trauma.  If no pulse is detected, provide CPR. If not breathing, provide
     artificial respiration.  If breathing is labored, administer oxygen or
     other respiratory support.

3.  Remove contaminated clothing as soon as possible.

4.  If eye exposure has occurred, eyes must  be flushed with lukewarm water for
     at least IS  minutes.

5.   Wash exposed skin areas twice with soap and water,

6.   Obtain authorization and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

7.   Transport to a health care facility.


Ingestion Exposure:

1.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration.  If breathing  is labored, administer oxygen or
     other respiratory support.

2.   Obtain authorization and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

3.   Give the victims water or milk:  children  up to 1 year old, 125 mL (4 oz
     or 1/2 cup); children  1 to 12 years old, 200 mL (6 oz or 3/4 cup); adults,
     250 mL (8  oz or 1 cup). Water or milk should be given only if victims
     are conscious and alert.

4.   Vomiting  may be induced with syrup of Ipecac.  If elapsed time since
     ingestion of formaldehyde is unknown or suspected  to be greater than
     30 minutes, do  not induce vomiting and  proceed to Step 5.  Ipecac  should
     not be administered to children under 6  months of age.

     Warning: Ingestion of formaldehyde may result in sudden onset of seizures
     or loss of consciousness. Syrup of Ipecac  should be administered only if
     victims are alert, have  an active gag-reflex, and show no signs of
     impending seizure or coma.  If ANY uncertainty exists, proceed to Step 5.

     The following dosages of Ipecac are recommended:  children up  to 1  year
     old, 10 mL (1/3 oz); children 1 to 12 years old, 15 mL (1/2 oz); adults,
     30 mL (1 oz).  Ambulate (walk) the victims and give large quantities'of
     water. If vomiting has not occurred after 15 minutes, Ipecac may  be
     readministered.  Continue to ambulate and give water to the victims.  If
     vomiting has not occurred within 15 minutes after second administration of
     Ipecac, administer activated charcoal.

5.   Activated charcoal may be administered if victims are conscious and alert.
     Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g (1-3/4 to 3-1/2 oz)
     for adults, with 125 to 250 mL (1/2 to 1  cup) of water.

6.   Promote excretion  by administering a saline cathartic or sorbitol to
     conscious and alert victims. Children  require 15 to  30 g (1/2 to  1 oz) of
     cathartic; 50 to 100 g (1-3/4 to 3-1/2 oz) is recommended  for adults.

7.   Transport to a health care facility.

SECTION IX -- EMERGENCY TREATMENT INFORMATION

    Signs and Symptoms of Exposure:  Headaches, blurred vision, confusion,
    drowsiness, fatigue, diarrhea, and pain have been occasionally noted.
    These do not appear to be dose related by intravenous administration.
    Fever and anorexia occur in 15 percent of patients.  Hair loss, sloughing
    of skin, and loss of feeling occur in approximately 4 percent of patients.
    Labored breathing, cough and pneumonia occur in some cases.  Renal toxicity
    is sometimes observed  (*AMA  1977).

    Emergency and First Aid Procedures:  Seek immediate medical care.  Skin
    decontamination should be thorough, with water and soap. Eye exposure can
    be followed by irrigation of eyes with  plain tap water (*Rumack 1975 to
    Present). (Non-Specific - Medicines, n.o.s.)  If not breathing, give
    artificial respiration.  If breathing is difficult, give oxygen.  Remove
    and isolate contaminated clothing and  shoes at the site. Keep victim quiet
    and maintain normal body temperature (DOT 1984, Guide  11).

SECTION IV   (continued)

        UEL:  73% (*Sax 1975)

    Extinguishing  Methods: Small fires:  dry chemical, carbon dioxide, water
    spray or foam. Large fires:  water spray, fog or foam.  Move container
    from fire area if you can do so without risk.  Do not get water inside
    container. Spray cooling water on containers exposed to flames until well
    after fire is out.  Withdraw immediately in case of rising sound from
    venting safety device or any discoloration of  tank due to fire (DOT 1984,
    Guide 29).

    Special Fire Fighting Procedures: Keep unnecessary people away; stay
    upwind; keep  out of low  areas. Isolate for  1/2 mile in all directions if
    tank car or truck is involved in fire (*DOT 1984).  Wear self-contained
    breathing apparatus; wear goggles if eye protection not provided.  Shut off
    flow of gas or liquid and keep cooling water  streams on exposed tanks or
    containers.  Use water  spray carefully in vicinity of dusts so as not to
    create dust clouds (*NFPA 1978).

    Unusual Fire and Explosion Hazards:  Toxic vapors such as carbon dioxide
    and carbon monoxide are generated during combustion  (*Environment Canada
    1982).  Explosion hazard: when aqueous formaldehyde  solutions are heated
    above their flash points, a potential for explosion hazard exists. High
    formaldehyde  concentration or methanol content lowers flash point.  Reacts
    with nitrogen  oxides at about  180; the reaction  becomes explosive. Also
    reacts violently with perchloric acid-aniline, performic acid,
    nitromethane,  magnesium carbonate, and hydrogen peroxide (Sax 1984, p.
    1452).

SECTION IX - EMERGENCY TREATMENT INFORMATION

      Signs and Symptoms of Exposure: Loss of appetite and nausea are earliest
      symptoms, with other symptoms of diarrhea, inflammation or sores in the
      mouth, gastric burning, and intestinal discomfort. More serious symptoms
      are due to the suppression of  bone marrow, with decrease of white cell
      count and blood platelets, and anemia.  Hair loss, nail changes,
      dermatitis,  and pigmentation  and atrophy of skin also occur (*Goodman
      1975).

      Emergency  and First Aid Procedures:  (Non-Specific -- Drugs)   Move victim
      to fresh air; call emergency medical care.  If not breathing, give
      artificial respiration.  If  breathing is difficult, give oxygen. In case
      of contact with material, immediately flush skin or  eyes with  running
      water for at least 15 minutes. Remove and isolate contaminated clothing
      and shoes at the site.  Keep victim quiet and maintain normal body

    Other Limits Recommended:  Not Found

    Routes of Entry:  Inhalation:  Yes (Sax 1984, p. 1997)
                     Skin:  Yes (Merck 1983, p. 935)
                     Ingestion:  Yes (Sax 1984, p. 1997)

    Health Hazards (Acute, Delayed, and Chronic):  It is classified as super
    toxic. Probable oral lethal dose in humans is less than 5 mg/kg or  a taste
    (less than 7 drops) for a 70 kg (150 Ibs.) person (*Gosselin  1976). It may
    be assumed that ingestion of 40-60 mg of nicotine is lethal to humans.
    There is fundamental  difference between  acute toxicity from use of nicotine
    as insecticide or from ingestion, and chronic toxicity that  may be caused
    by prolonged exposure to small doses as occurs in smoking (*Encyc Occupat
    Health and Safety 1983).  Maternal smoking during pregnancy is associated
    with increased risk of spontaneous abortion, low birth weight and
    still-birth (*The Chemical Society 1975).  Nicotine was found as a
    co-carcinogen in animals (*NRC 1977).

    Medical Conditions Generally Aggravated  by Exposure: Not Found


SECTION IV - FIRE AND EXPLOSION HAZARD DATA

    Flash Point (Method Used):  Not Found
    Flammable Limits: Low fire hazard when exposed to heat or flame (Sax
    1984, p. 1997)
        LEL:  0.75% (Sax  1984, p. 1997)
        UEL:  4.0% (Sax  1984, p. 1997)

    Extinguishing Methods:  Extinguish with alcohol foam, dry chemical, or
    carbon dioxide (Sax 1984, p. 1997).  Water may cause frothing if it gets
    below surface  of liquid and  turns to steam.  However, water fog gently
    applied to surface will cause frothing which will extinguish the fire
    (*NFPA 1978).

    Special Fire Fighting  Procedures:  Material too dangerous  to health to
    expose firefighters.  A few whiffs of the  vapor could cause death; vapor or
    liquid could be fatal on penetrating firefighter's normal full protective
    clothing.  Normal full protective clothing and breathing apparatus
    available to the average fire department will not provide adequate
    protection against inhalation or skin  contact (*NFPA 1978).

Gastrointestinal effects include nausea, vomiting, abdominal pain or burning
sensation, and diarrhea.  Increased  salivation, lacrimation (tearing), and
sweating may be noted.
Emergency Life-Support Procedures:

Acute exposure to nicotine may require decontamination and life support for the
victims.  Emergency personnel  should wear  protective clothing  appropriate to
the type   and  degree   of contamination.   Air-purifying or  supplied-air
respiratory equipment should also be  worn,  as  necessary.   Rescue vehicles
should carry supplies such  as plastic  sheeting and disposable plastic bags to
assist  in preventing spread of  contamination.
Inhalation Exposure:

1.   Move victims to fresh air.  Emergency personnel should avoid self-exposure
     to nicotine.

2.   Evaluate vital  signs including pulse and  respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not  breathing, provide
     artificial respiration.    If  breathing is labored, administer oxygen or
     other respiratory support.

3.   Obtain authorization and/or further  instructions from the local hospital
     for  administration  of an  antidote or  performance of  other invasive
     procedures.

4.   RUSH to a health care facility.
Dermal/Eye Exposure:

1.  Remove victims from exposure.   Emergency  personnel should  avoid self-
     exposure to nicotine.

2.  Evaluate vital  signs including pulse and  respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not  breathing, provide
     artificial   respiration.   If  breathing is labored, administer oxygen or
     other respiratory support.

3.  Remove contaminated clothing as soon as possible.

4.  If  eye exposure has occurred,  eyes must be flushed with lukewarm water for
     at least 15 minutes.

5.  THOROUGHLY wash exposed skin areas with soap  and water.

6.  Obtain authorization   and/or  further  instructions from the local hospital
     for  administration  of  an   antidote or  performance  of other invasive
     procedures.

7.  RUSH to a health care facility.

2.   DO NOT induce vomiting or attempt to neutralize!

3.   Obtain authorization and/or  further  instructions from  the local hospital
     for administration  of an  antidote or  performance  of other invasive
     procedures.

4.   Give the victims water or milk:  children up to  1 year old, 125  mL (4 oz
     or 1/2 cup); children  1 to 12 years old, 200 mL (6 oz or 3/4 cup); adults,
     250 mL (8 oz or 1 cup).  Water or milk  should  be given only if  victims are
     conscious and alert.

5.   Activated charcoal may be administered if victims are conscious and alert.
     Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g (1-3/4 to 3-1/2 oz)
     for adults,  with 125 to 250 mL (1/2 to 1 cup) of water.

6.   Promote  excretion by  administering a  saline  cathartic or  sorbitol to
     conscious and alert victims.  Children require  15 to 30 g (1/2 to 1  oz)
     of cathartic; 50 to 100 g (1-3/4 to 3-1/2 oz) is recommended  for adults.

                                   PARATHION

The heart rate may decrease following oral exposure or increase following
dermal exposure.  Hypotension (low blood pressure) is not uncommon.
Respiratory symptoms include dyspnea (shortness of breath), respiratory
depression, and respiratory paralysis.  Psychosis may occur.
Emergency Life-Support Procedures:

Acute exposure to parathion may require decontamination and life support for
the victims. Emergency personnel should wear protective clothing appropriate
to the type and degree of  contamination.  Air-purifying or supplied-air
respiratory equipment should also be worn, as necessary.  Rescue vehicles
should carry supplies such as plastic sheeting and disposable plastic bags to
assist in preventing spread of contamination.
Inhalation Exposure:

1.   Move  victims to fresh air.  Emergency personnel should avoid self-exposure
     to parathion.

2.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

3.   Obtain authorization and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

4.   Transport to a health care facility.
Dermal/Eye Exposure:

1.   Remove victims from exposure.  Emergency personnel should avoid self-
     exposure to parathion.

2.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

3.   Remove contaminated clothing as soon as possible.

4.   If  eye exposure has occurred, eyes must be flushed with lukewarm water for
     at least 15  minutes.

Ingestion Exposure:

1.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

2.   Obtain authorization and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

3.   Vomiting  may be induced with syrup of Ipecac.  If elapsed time since
     ingestion of parathion is unknown  or suspected to be greater than
     30 minutes, do not induce vomiting and  proceed to Step 4.  Ipecac  should
     not be administered to children under 6  months of age.

     Warning: Ingestion of parathion may result in sudden onset of seizures or
     loss of consciousness.  Syrup of Ipecac should be administered only if
     victims are alert, have an active gag-reflex, and show no signs of
     impending seizure or coma.  If ANY uncertainty exists,  proceed to Step 4.

     The following dosages of Ipecac are recommended: children up to 1 year
     old, 10 mL (1/3  oz); children 1 to 12 years old,  15 mL (1/2 oz); adults,
     30 mL (1 oz).  Ambulate (walk) the victims and give large quantities of
     water. If vomiting has not occurred after 15 minutes, Ipecac may  be
     readministered.  Continue to ambulate and  give water to  the victims.  If
     vomiting has not occurred within 15 minutes after second administration of
     Ipecac, administer activated charcoal.

4.   Activated charcoal may be administered if victims are conscious and alert.
     Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g  (1-3/4 to 3-1/2 oz)
     for adults, with  125 to 250 mL (1/2 to 1  cup) of water.

5.   Promote excretion by administering a saline  cathartic or sorbitol to
     conscious and alert victims. Children  require 15 to 30 g (1/2 to 1 oz)
     of cathartic; 50  to 100 g (1-3/4 to 3-1/2 oz) is recommended  for adults.

6.   Transport to a health care facility.

Ingestion Exposure:

1.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

2.   Obtain authorization and/or  further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

3.   Vomiting  may be induced with syrup of Ipecac.  If elapsed time since
     ingestion of coumaphos is unknown or suspected to be greater than
     30 minutes,  do not induce vomiting and  proceed to Step 4.  Ipecac should
     not be administered  to children under 6  months of age.

     Warning: Ingestion of coumaphos  may result in sudden onset  of seizures or
     loss of consciousness.  Syrup of Ipecac should be administered only if
     victims are alert, have an active gag-reflex, and show no signs of
     impending seizure or coma.   If ANY uncertainly exists, proceed to Step 4.

     The following dosages of Ipecac are recommended: children up to 1 year
     old, 10 mL (1/3 oz);  children  1 to  12 years old, 15 mL (1/2  oz); adults,
     30 mL (1 oz).  Ambulate (walk) the victims and give large quantities of
     water. If vomiting has not  occurred after 15 minutes, Ipecac may be
     readministered.  Continue to ambulate and give water to  the victims.  If
     vomiting has not occurred within  15 minutes after  second administration of
     Ipecac, administer activated charcoal.

4.   Activated charcoal may be administered if victims are conscious and alert.
     Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g (1-3/4 to
     3-1/2 oz) for adults, with 125 to 250 mL (1/2 to 1 cup) of water.

5.   Promote excretion by  administering a saline cathartic or sorbitol to
     conscious and alert victims. Children require 15 to 30 g (1/2 to 1 oz)
     of cathartic; 50  to 100 g (1-3/4 to  3-1/2 oz) is recommended for adults.

6.   Transport to a health  care facility.

edema and hypotension (low blood pressure) are common.  Dimethylhydrazine is
toxic to  the liver,  ruptures red  blood cells, and may  cause kidney damage.
Dermal contact may result in strong skin and mucous membrane irritation.


Emergency Life-Support Procedures:

Acute exposure  to  dimethylhydrazine may  require  decontamination  and life
support for the victims.  Emergency  personnel should  wear protective clothing
appropriate  to  the  type  and  degree of contamination.   Air-purifying or
supplied-air respiratory equipment should also be  worn, as  necessary. Rescue
vehicles should carry supplies such as dimethylhydrazine-resistant sheeting and
disposable bags to assist in preventing spread of contamination.


Inhalation Exposure:

1.  Move victims to fresh air.  Emergency personnel should avoid self-exposure
      to dimethylhydrazine.

2.  Evaluate vital  signs including  pulse  and respiratory rate, and note any
      trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
      artificial respiration.   If breathing is labored, administer oxygen or
      other respiratory support.

3.  Obtain authorization and/or further   instructions from  the local hospital
      for  administration  of  an antidote  or performance  of other invasive
      procedures.

4.  Transport to a health care facility.


Dermal/Eye Exposure:

1.  Remove victims from exposure.   Emergency  personnel  should  avoid self-
      exposure to dimethylhydrazine.

2.  Evaluate vital  signs including  pulse  and  respiratory rate, and note any
      trauma.  If no pulse is detected, provide CPR.  If not  breathing, provide
      artificial respiration.   If breathing  is labored, administer oxygen or
      other respiratory support.

3.  Remove contaminated clothing as soon as possible.

4.  If eye exposure has occurred, eyes must be flushed with lukewarm water for
      at least 15 minutes.

                                   STRYCHNINE

Victims may also experience stiffness, painful  muscle cramping  (especially in
the legs),  and opisthotonos (spasm in which the spine and extremities are bent
with convexity forward, the body resting on the head and heels).  Vomiting and
renal failure,  as well  as cyanosis  (blue tint  to skin and mucous membranes)
and rhabdomyolysis (destruction of skeletal muscle), may be found.
Emergency Life-Support Procedures:

Acute exposure to strychnine may require  decontamination and  life support for
the victims.  Emergency  personnel should wear protective clothing appropriate
to the  type and  degree  of contamination.   Air-purifying or supplied-air
respiratory  equipment  should also  be  worn,  as necessary. Rescue vehicles
should carry supplies such as plastic sheeting and  disposable plastic  bags to
assist in preventing spread of contamination.
Inhalation Exposure:

1.   Move  victims to fresh air.  Emergency personnel should avoid self-exposure
     to strychnine.

     Warning:  Any unnecessary sensory input may induce seizures.   Isolate the
     victims from any avoidable distractions.

2.   RUSH to a health care facility!

3.   Evaluate vital  signs including  pulse and  respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not  breathing, provide
     artificial  respiration.    If  breathing  is labored, administer oxygen or
     other respiratory support.

4.   Obtain authorization and/or further  instructions from the local hospital
     for  administration  of an  antidote or  performance  of  other invasive
     procedures.
Dermal/Eye Exposure:

1.  Remove victims from exposure.   Emergency  personnel should  avoid self-
     exposure to strychnine.

     Warning:   Any unnecessary sensory input may induce seizures.  Isolate the
     victims from any avoidable distractions.

SECTION IX - EMERGENCY TREATMENT INFORMATION

    Signs and Symptoms of Exposure: Inhalation causes irritation of  nose,
    throat, and respiratory tract.  Contact of liquid with eyes causes
    irritation and tears.  Contact with skin causes irritation and blistering;
    fluid from blisters may cause additional blistering of adjacent skin.
    Ingestion causes burns of mouth and stomach (Weiss 1980, p. 776).

    Emergency and First Aid Procedures:  Get medical attention following all
    exposures to this compound.  In case of inhalation, move victim to fresh
    air; if breathing has stopped,  give artificial respiration.  If there  has
    been eye contact, flush eyes with water for at least 15 minutes. In case
    of skin  contact, flush with water (Weiss 1980, p. 776).

SECTION III - HEALTH HAZARD DATA

    OSHA PEL:  Ceiling 0.35 mg/m3 (skin) (*NIOSH/RTECS  1985)

    ACGIH  TLV:  Ceiling 0.35 mg/m3 (skin) (*ACGIH 1983)

    IDLH: 5 ppm  (*Encyc Occupat Safety and Health 1983)

    Other Limits Recommended:  Methyl hydrazine is a suspected human carcinogen
    with a NIOSH recommended ceiling concentration of 0.08 mg/m3/2 hour (*ACGIH
    1984 and *NIOSH 1985).  SPEGL 0.24 ppm (60 minutes) (NRC 1985b, pp. 23-36).

    Routes of Entry:  Inhalation:  Yes (*Clayton and Clayton 1981-82)
                     Skin:  Yes (*Clayton and Clayton 1981-82)
                     Ingestion:  Yes (*Clayton and Clayton 1981-82)

    Health Hazards (Acute,  Delayed, and Chronic):  Methyl hydrazine  vapors are
    extremely toxic and the  liquid is corrosive to skin.  Methyl  hydrazine is
    the strongest convulsant and the most toxic of methyl-substituted hydrazine
    derivatives (*Clayton and Clayton 1981-82). It is more toxic than
    hydrazine (*NFPA 1978). At high doses, it is a strong central nervous
    system poison  that can lead to convulsions and death (*Encyc Occupat Health
    and Safety 1971)

    Medical Conditions Generally Aggravated by Exposure: Skin rash may be
    aggravated by skin exposure (*Encyc Occupat  Health and Safety 1971).


SECTION IV - FIRE AND EXPLOSION HAZARD DATA

    Flash Point (Method Used): 70C (OC) (*Merck 1983)
    Flammable Limits:
         LEL: 2.5% (Sax 1984, p. 1858)
         UEL:  97% (Sax 1984, p. 1858)

    Extinguishing  Methods:  For small fires, use dry chemical, carbon dioxide,
    water spray, and foam.  For large fires, use water spray,  fog, or foam.
    Keep unnecessary people away and isolate the hazardous area. Stay upwind
    and keep out of low-lying areas (DOT 1984, Guide 28).  Fire exposed
    containers should be kept cool with water. Use water spray to disperse
    vapors and protect men  attempting to stop a leak which has not ignited
    (*NFPA 1978). Move container from fire area if it can be  done without risk
    (*DOT 1984).

    Special  Fire Fighting Procedures: Wear positive pressure breathing
    apparatus and special (full) protective clothing.  No skin surface should
    be exposed (*NFPA 1978). Isolate area for 1/2-mile in all directions if a
    tank car or truck is involved in a fire (DOT 1984, Guide 28).

    Unusual Fire and Explosion Hazards:  Extremely flammable; ignites
    spontaneously under almost all normal temperature conditions (*NFPA 1978).
    Water used to  extinguish a fire may cause pollution and  should be  diked for

SECTION IV   (continued)

    later disposal (DOT 1984, Guide 28).  Water may be ineffective in
    extinguishing fires due to the chemical's low flash point.  Because of the
    wide flammability limits, low flash point, and reignition hazard, dry
    chemicals, carbon dioxide, water spray, and foam may not be as effective as
    water dilution of fire area.  The vapor is heavier than air; thus it may
    accumulate sufficiently to flash back (*NFPA 1978).

    NFPA Flammability Rating: 3


SECTION V - REACTIVITY DATA

    Stability:  Unstable:  Yes (*NFPA 1978)
               Stable:

         Conditions to Avoid:  Heat or flame should be avoided because
         chemical is extremely flammable and explosive (*Sax  1979).

    Incompatibility (Materials to Avoid):  Ignites spontaneously in air when
    in contact with porous materials (e.g., earth, asbestos, wood, or  cloth)
    (*NFPA 1978).  Also ignites spontaneously on contact with strong oxidizing
    agents (e.g., fluorine, chlorine trifluoride, fuming nitric acid, and
    nitrogen tetroxide) (*Merck 1983).

    Hazardous Decomposition or Byproducts:  Methylhydrazine fires produce
    irritating nitrogen oxides (*NFPA 1978).

    Hazardous Polymerization:  May Occur:  Not Found
                              May Not Occur: Not Found

         Conditions to Avoid:  Not Found
SECTION VI ~ USE INFORMATION

    Used as a chemical intermediate and solvent (*ACGIH 1980).  Also used as a
    component of rocket propellants (*SRI).
SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE
(Steps to be Taken in Case Material is Released or Spilled)

    In the case of a spill or leak, shut off ignition sources, and extinguish
    or disallow flares, smoking, or flames in the hazard area.  Do not touch
    the spilled material, and stop leak if  it can be done without risk. Use
    water spray to reduce vapors.  For small spills, take up the chemical with
    sand or other noncombustible absorbent material and  place it in containers
    for later disposal. For large spills, dike far ahead for later disposal
    (*DOT 1984).

Emergency Life-Support Procedures:

Note: Victims at special risk include individuals with glucose-6-phosphate-
dehydrogenase deficiency, those with liver and kidney disorders, blood
diseases, or a history of alcoholism.

Acute exposure to aniline may  require decontamination and life support for the
victims.  Emergency personnel should wear protective  clothing appropriate to
the type and degree of contamination.  Air-purifying or supplied-air
respiratory equipment should also be worn, as necessary.  Rescue vehicles
should carry supplies such as plastic sheeting and disposable plastic bags to
assist in preventing spread of contamination.


Inhalation Exposure:

1.   Move victims to fresh air.  Emergency personnel should avoid self-exposure
     to aniline.

2.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma. If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

3.   Obtain authorization and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

4.   RUSH to a health care facility.
Dermal/Eye Exposure:

1.   Remove victims from exposure.  Emergency personnel should avoid self-
     exposure to aniline.

2.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

3.   Remove contaminated clothing as soon as possible.

4.   If eye exposure has occurred, eyes must be flushed with lukewarm water for
     at least 15 minutes.

5.   Wash exposed skin areas  twice with soap and water.

6.   Obtain authorization  and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

7.   RUSH to a health care facility.

Ingestion Exposure:

1.  Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

2.  Obtain authorization and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

3.  Vomiting may be induced with syrup of Ipecac.  If elapsed time since
     ingestion of aniline is unknown or suspected to be greater than
     30 minutes, do not induce  vomiting and proceed to Step 4.  Ipecac should
     not be administered to children under 6 months of age.

     Warning: Ingestion of aniline may result in sudden onset of seizures or
     loss of consciousness.  Syrup of Ipecac should be administered only if
     victims are alert, have an active gag-reflex, and show no signs of
     impending seizure or coma.  If ANY uncertainty exists, proceed to Step 4.

     The following dosages of Ipecac are recommended:  children up to  1 year
     old, 10 mL (1/3 oz); children 1 to 12 years old, 15 mL (1/2 oz); adults,
     30 mL (1 oz).  Ambulate (walk) the victims and give large quantities of
     water. If vomiting has not occurred after 15 minutes,  Ipecac may be
     readministered.  Continue  to ambulate and  give water to the victims.  If
     vomiting has not occurred  within 15 minutes after second administration of
     Ipecac, administer activated charcoal.

4.  Activated charcoal may be administered if victims are conscious and alert.
     Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g (1-3/4 to 3-1/2 oz)
     for adults, with 125 to 250 mL (1/2 to 1 cup) of water.

5.  Promote excretion by administering a saline  cathartic or sorbitol to
     conscious and alert victims. Children  require 15 to 30  g (1/2 to 1 oz)
     of cathartic; 50  to 100 g (1-3/4 to 3-1/2 oz) is recommended  for adults.

6.  RUSH  to a health care facility.

    1,1-dimethylhydrazine (*SRI).
SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE
(Steps to be Taken in Case Material is Released or Spilled)

    Avoid inhalation and skin contact (see Section III above). Spills can be
    absorbed by celite or commercial spill absorbent. After absorbent
    containing major share of nitrosamine has been picked-up (avoid dusts; do
    not sweep), surface should be thoroughly cleaned with strong detergent
    solution.  If major spill occurs outside of ventilated area, room should be
    evacuated and cleanup operation should be carried out by persons equipped
    with self-contained breathing apparatus (*NRC 1981).
SECTION VIII - PROTECTIVE EQUIPMENT FOR EMERGENCY SITUATIONS

    For emergency situations, wear a positive pressure, pressure-demand,
    full facepiece self-contained breathing apparatus (SCBA) or pressure-

Emergency Life-Support Procedures:

Acute exposure  to cycloheximide  may require  decontamination and life support
for the  victims.   Emergency  personnel  should wear   protective  clothing
appropriate to  the  type and  degree  of contamination.   Air-purifying or
supplied-air respiratory equipment should also be  worn, as necessary.  Rescue
vehicles should  carry supplies such as plastic sheeting and disposable plastic
bags to assist in preventing spread of contamination.


Inhalation Exposure:

1.   Move victims to fresh air. Emergency personnel should avoid self-exposure
     to cycloheximide.

2.   Evaluate vital signs including  pulse and respiratory  rate, and note any
     trauma.  If no pulse is detected, provide CPR. If not  breathing, provide
     artificial respiration.    If  breathing is labored, administer oxygen or
     other respiratory support.

3.   Obtain authorization and/or further  instructions from the local hospital
     for  administration  of  an antidote or performance  of  other invasive
     procedures.

4.   Transport to a health care facility.
Dermal/Eye Exposure:

1.   Remove victims from exposure.   Emergency  personnel  should  avoid self-
     exposure to cycloheximide.

2.   Evaluate vital signs including  pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration.    If  breathing is labored, administer oxygen or
     other respiratory support.

3.   Remove contaminated clothing as soon as possible.

4.   If eye exposure has occurred, eyes must be flushed with lukewarm water for
     at least 15 minutes.

5.   Wash exposed skin areas THOROUGHLY with soap and water.

6.   Obtain authorization  and/or further  instructions from the local hospital
     for  administration  of an  antidote or performance of  other invasive
     procedures.

Ingestion Exposure:

1.   Evaluate vital signs including pulse and  respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not  breathing, provide
     artificial respiration.    If  breathing is labored, administer oxygen or
     other respiratory support.

2.   Obtain authorization and/or further  instructions from  the local hospital
     for administration  of an  antidote or  performance  of other invasive
     procedures.

3.   Vomiting may be induced with syrup  of  Ipecac.   If elapsed  time since
     ingestion of cycloheximide is unknown or suspected to be greater than
     30 minutes, do  not induce vomiting and proceed to Step 4. Ipecac should
     not be administered to children under 6 months of age.

     Warning:   Ingestion  of cycloheximide may  result in  sudden onset of
     seizures  or  loss  of  consciousness.    Syrup  of   Ipecac  should be
     administered only if victims  are alert, have an active gag-reflex, and
     show no signs of impending seizure or coma.  If  ANY uncertainty exists,
     proceed to Step 4.

     The following  dosages of  Ipecac are recommended: children up to 1 year
     old, 10 mL (1/3 oz); children 1 to  12 years old, 15  mL (1/2  oz); adults,
     30 mL (1 oz).   Ambulate  (walk) the victims and give large quantities of
     water. If vomiting has not  occurred  after  15 minutes,  Ipecac  may be
     readministered.   Continue to ambulate and give water to the  victims. If
     vomiting has not occurred within  15 minutes after second administration of
     Ipecac, administer activated charcoal.

4.   Activated charcoal may be administered if victims are conscious and alert.
     Use 15 to 30 g (1/2 to  1 oz) for children,  50 to 100 g (1-3/4 to  3-1/2 oz)
     for adults, with 125 to 250 mL (1/2 to 1 cup) of water.

5.   Promote  excretion  by  administering a saline cathartic  or sorbitol to
     conscious and alert victims.  Children require 15  to 30 g (1/2 to 1 oz)
     of cathartic; 50  to 100 g (1-3/4 to  3-1/2 oz) is recommended for adults.

6.   Transport to a health care facility.

    Health Hazards (Acute, Delayed, and Chronic): Methyl bromide is a
    dangerous cumulative poison with delayed symptoms of central nervous system
    intoxication that may appear as long as several months after exposure
    (*White-Stevens 1971). High concentrations can produce fatal pulmonary
    edema. Chronic exposure can cause central nervous system depression and
    kidney injury (*Merck 1976). It may cause severe and permanent brain
    damage. Severe neurological signs may appear when there is a sudden
    exposure to high concentrations following continuous slight  exposure
    (*Encyc Occupat Health  and Safety 1971). Methyl bromide has practically no
    odor or irritating effects and therefore no warning, even at hazardous
    concentrations (*Clayton and Clayton 1981-82).

Signs and Symptoms of Acute Methyl Bromide Exposure:

Warning:  Effects may be delayed for hours to days.  Caution is advised.

Signs and symptoms  of  acute  exposure  to methyl bromide may be severe and
include tremors, convulsions, brain hemorrhage, paralysis, coma, and permanent
brain damage.  Respiratory effects include cough, tachypnea (rapid respiratory
rate), pulmonary edema, and respiratory collapse. Cyanosis  (blue tint to the
skin and  mucous membranes),  pallor, ventricular fibrillation, and circulatory
collapse may also occur.  Lethargy,  profound  weakness, headache, dizziness,
mental confusion,  slurring of  speech, staggering gait,  and blurred or double
vision are often found.

Gastrointestinal signs and symptoms include nausea,  vomiting,  abdominal pain,
and anorexia.  Oliguria  (scanty  urination), anuria  (lack of urine formation),
kidney hemorrhage, and kidney failure may occur.   Contact with  methyl bromide
may  cause  dermatitis (red, inflamed skin) and conjunctivitis (red, inflamed
eyes).


Emergency Life-Support Procedures:

Acute exposure to methyl bromide may require decontamination and life support
for  the   victims.    Emergency  personnel should  wear  protective  clothing
appropriate  to  the  type and  degree of  contamination.  Air-purifying or
supplied-air respiratory equipment should also be  worn, as necessary. Rescue
vehicles should carry supplies such as plastic sheeting  and disposable plastic
bags to assist in preventing spread of contamination.


Inhalation Exposure:

1.  Move victims to fresh air.  Emergency personnel should avoid self-exposure
      to methyl bromide.

2.  Evaluate vital signs including pulse and respiratory rate,  and note any
      trauma.  If no pulse is detected, provide CPR. If not breathing, provide
      artificial respiration.  If breathing  is  labored,  administer oxygen or
      other respiratory support.

3.  Obtain authorization  and/or further  instructions from the  local hospital
      for  administration of an  antidote  or performance  of  other, invasive
      procedures.

4.  Transport to a health care facility.

                      HYDROCYANIC ACID (HYDROGEN CYANIDE)

Signs and Symptoms of Acute Hydrocyanic Acid Exposure:

Warning:   Hydrocyanic  acid  may  be fatal if inhaled, swallowed, or absorbed
through skin or mucous  membranes.- Caution is advised.

Signs and symptoms  of acute exposure  to hydrocyanic  acid may include
hypertension (high blood pressure) and tachycardia (rapid heart rate), followed
by hypotension (low blood pressure) and bradycardia (slow heart rate).  Cherry
red mucous  membranes and  blood may be noted.   Cardiac arrhythmias  and other
cardiac abnormalities are common. Cyanosis (blue tint  to the  skin and mucous
membranes) may be observed.

Weakness,  headache, vertigo  (dizziness),  agitation,  giddiness, salivation,
nausea, and vomiting,  may  be  followed  by combative  behavior, convulsions,
paralysis, protruding  eyeballs,  dilated and  unreactive  pupils,  and coma.
Tachypnea (rapid, shallow respirations) or  hyperpnea (rapid, deep respirations)
may be followed by respiratory depression.  Lung hemorrhage and pulmonary edema
may also occur.

Hydrocyanic acid is may be irritating to the skin, eyes, and mucous membranes.
Lacrimation  (tearing)  and  a  burning  sensation  of the mouth and throat are
common.


Emergency Life-Support  Procedures:

Acute exposure to hydrocyanic acid may require decontamination and life support
for the  victims.   All exposed  persons  should be transported to a health care
facility as quickly as  possible.  Emergency personnel should wear protective
clothing  appropriate to the type and  degree of contamination. Air-purifying or
supplied-air respiratory equipment should also be  worn, as necessary.  Rescue
vehicles should  carry  supplies such as plastic sheeting and disposable plastic
bags to assist in preventing spread of contamination.


Inhalation Exposure:

1.  Move victims to fresh air. Emergency  personnel should avoid self-exposure
      to hydrocyanic acid.

2.  Evaluate vital  signs including  pulse and respiratory rate,  and note any
      trauma.  If no pulse is detected, provide CPR.  If not  breathing, provide
      artificial respiration.   IMMEDIATELY  begin administering  100% oxygen to
      all  victims.  Monitor victims for respiratory distress.

      Warning:  To prevent self-poisoning, avoid mouth-to-mouth breathing; use
      a  forced-oxygen  mask.   Direct  oral contact  with  hydrocyanic  acid-
      contaminated  persons or  their  gastric  contents can  result in self-
      poisoning.

    Medical  Conditions Generally Aggravated by Exposure:  Not Found


SECTION IV - FIRE AND EXPLOSION HAZARD DATA

    Flash Point (Method Used): 0F, -18C (*Sunshine 1969)
    Flammable Limits:
        LEL:  3.9% (Weiss 1980, p. 618)
        UEL:  21.8% (Weiss 1980, p. 618)

    Extinguishing Methods: Small fires: let burn unless  leak can be stopped
    immediately.  Large fires:  water spray, fog, or foam. Move container from
    fire area if you can do so without risk. Stay away from ends of tanks.
    Withdraw immediately in case of rising sound from venting safety device or
    any discoloration of tank due to fire.  Cool container with water using
    unmanned device until well after fire  is out. Isolate area until gas has
    dispersed (DOT 1984, Guide  13).  Preferably let fire  burn, stop  gas flow.
    Fires  may be extinguished with dry chemical, foam,  or carbon dioxide (Weiss
    1980,  p.  618).

    Special Fire Fighting Procedures:  Keep unnecessary people away; isolate
    hazard area and deny entry. Stay upwind; keep out  of low areas. Ventilate
    closed spaces before entering them. Wear positive pressure  breathing
    apparatus and special protective clothing. Evacuate  area endangered by
    gas.  Isolate for 1/2 mile in all directions if tank car or truck is
    involved in fire (DOT 1984, Guide 13).

    Unusual Fire and Explosion Hazards:  Combustion produces irritating sulfur
    dioxide.  Flash back along vapor track may occur (*CHRIS 1978), Very
    dangerous when exposed to heat, flame, or oxidizers.  On decomposition it
    emits highly toxic fumes of sulfur oxides.  It will react with water, steam
    or acids to produce toxic and flammable vapors; and can react vigorously
    with oxidizing materials (Sax 1984, p.  1764).

Signs and Symptoms of Acute Carbon Disulfide Exposure:

Warning:  Effects may be delayed.  Caution is advised.

Acute exposure to  carbon  disulfide primarily  affects  the central nervous
system producing signs and  symptoms that may  include headache, dizziness,
difficulty  swallowing, nervousness,  tremors,  mental depression, delirium,
psychosis, convulsions, paralysis, and coma. Nausea, vomiting, cyanosis (blue
tint to skin and  mucous membranes), hypothermia (low  body temperature), and
peripheral vascular collapse may also occur.

Respiratory effects include  coughing,  dyspnea  (shortness of  breath), and
respiratory  failure.    Carbon  disulfide  is  a  strong skin irritant; dermal
exposure may result in severe burns.   Eye exposure may  cause degeneration of
the retina and optic nerve.  Pupils may be dilated.


Emergency Life-Support Procedures:

Acute exposure to  carbon disulfide may require decontamination and life support
for the  victims.   Emergency personnel  should wear   protective  clothing
appropriate to  the  type  and degree  of contamination.   Air-purifying  or
supplied-air respiratory equipment should also be  worn, as necessary.  Rescue
vehicles should  carry supplies such as plastic sheeting and disposable plastic
bags to assist in preventing spread of contamination.


Inhalation Exposure:

1.   Move victims to fresh air.  Emergency personnel should avoid self-exposure
      to carbon disulfide.

2.   Evaluate vital signs including  pulse and respiratory rate, and note any
      trauma. If no pulse is detected, provide CPR. If not  breathing, provide
      artificial  respiration.    If  breathing is labored, administer oxygen or
      other respiratory support.

3.   Obtain authorization and/or further  instructions from the local hospital
      for  administration of an  antidote or performance  of  other invasive
      procedures.

4.   Transport to a health care  facility.

Gastrointestinal effects of acute  exposure may  include nausea, vomiting, and
abdominal pain.  Ethylene oxide may severely irritate or burn mucous membranes
and moist skin. Eye contact may result in conjunctivitis  (red, inflamed eyes)
and erosion  of the cornea.
Emergency Life-Support Procedures:

Acute exposure  to ethylene oxide may require decontamination and life support
for the  victims.   Emergency personnel  should  wear   protective clothing
appropriate to  the  type and degree  of  contamination.   Air-purifying or
supplied-air respiratory equipment should also be  worn,  as  necessary. Rescue
vehicles should  carry supplies such as plastic sheeting and disposable plastic
bags to assist in preventing spread of contamination.
Inhalation Exposure:

1.   Move victims to fresh air. Emergency personnel should avoid self-exposure
     to ethylene oxide.

2.   Evaluate vital signs including  pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration.   If  breathing is labored, administer oxygen or
     other respiratory support.

3.   Obtain authorization and/or further instructions from the local hospital
     for  administration  of an  antidote  or performance of  other invasive
     procedures.

4.   Transport to a health care facility.


Dermal/Eye Exposure:

1.   Remove victims from exposure.   Emergency  personnel  should  avoid self-
     exposure to ethylene oxide.

2.   Evaluate vital signs including  pulse and respiratory  rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration.   If  breathing is labored, administer oxygen or
     other respiratory support.

3.   Remove contaminated clothing  as soon as possible.

4.   If eye exposure  has  occurred,  eyes must  be IMMEDIATELY  flushed with
     lukewarm water for AT LEAST 15 minutes.

5.   If liquid  is spilled  on the skin, allow ethylene oxide to vaporize  before
     washing THOROUGHLY with soap and water.

     for  administration  of an antidote or  performance  of other invasive
     procedures.

7.   Transport to a health care facility.
Ingestion Exposure:

1.   Evaluate vital signs including  pulse and  respiratory rate,  and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration. If breathing is labored, administer  oxygen or
     other respiratory support.

2.   Obtain authorization  and/or further  instructions from the local hospital
     for administration  of an  antidote  or  performance  of other invasive
     procedures.

3.   Give the victims water or milk: children  up 1 year old, 125 mL (4 oz or
     1/2 cup); children 1 to 12 years old 200 mL (6  oz or 3/4 cup); adults,
     250 mL (8 oz or 1 cup).  Water or milk should be given only if victims are
     conscious and alert.

4.   Activated charcoal may be administered if victims are conscious and alert.
     Use 15 to 30 g (1/2 to  1 oz) for children, 50 to 100 g (1-3/4 to 3-1/2 oz)
     for adults, with 125 to 250 mL (1/2 to 1  cup) of water.

5.   Ethylene oxide generally acts  as its  own cathartic;  however, if  deemed
     necessary, excretion  may be  promoted by administering a saline cathartic
     or sorbitol to conscious and alert victims.  Children require 15 to 30 g
     (1/2 to  1  oz)  of cathartic;  50 to  100 g (1-3/4  to 3-1/2  oz) is
     recommended for adults.

6.   Transport to a health care facility.

    Health Hazards (Acute, Delayed, and Chronic): Phosgene is a lung toxicant
    that causes damage to the capillaries,  bronchioles and. alveoli of the lungs
    (U.S. Army  1975, p. 3-1) by decomposition to hydrochloric acid.  There is
    little immediate irritant  effect upon the respiratory tract, and the
    warning properties of the gas  are therefore very slight.  Pulmonary edema,
    bronchopneumonia and occasionally lung abscesses develop.  Degenerative
    changes  in the nerves have been reported as later developments. A
    concentration of 25 ppm is dangerous for exposures lasting  30-60 minutes
    and 50 ppm is rapidly fatal after even short exposure (Sax  1984, p. 2210).

                             TRIMETHYLCHLOROSILANE

Acute inhalation exposure may  result in  hoarseness, laryngitis,  a feeling of
suffocation,  dyspnea  (shortness  of  breath),  choking, respiratory tract
irritation, chest pain, and pulmonary edema.  The  potential for circulatory
collapse  is  high following  ingestion  of trimethylchlorosilane. Sneezing,
bleeding of  the nose and gums, and ulceration of the nasal and oral mucosa may
also occur.  Renal toxicity has been observed in animals.

If the  eyes come  in contact  with trimethylchlorosilane, irritation, pain,
swelling, corneal erosion,  and  blindness  may result.   Dermal  exposure is
generally followed  by dermatitis (red, inflamed skin), severe burns, pain, and
shock.

Acute inhalation exposure may result in  hoarseness, laryngitis,  a feeling of
suffocation,  dyspnea  (shortness  of  breath),  choking,  respiratory  tract
irritation, chest pain, and pulmonary edema.   Sneezing,  bleeding of  the nose
and gums,  and ulceration  of the  nasal and oral mucosa may also occur. Renal
toxicity has been observed in animals.

If the eyes have come in  contact with methyltrichlorosilane, then irritation,
pain, swelling,  corneal erosion,  and blindness may result  Dermatitis (red,
inflamed skin), severe burns, pain, and shock generally follow dermal exposure.
Emergency Life-Support Procedures:

Acute exposure  to methyltrichlorosilane may require decontamination and life
support for the victims.  Emergency personnel should wear protective clothing
appropriate to  the  type and degree  of  contamination.   Air-purifying  or
supplied-air respiratory equipment should  also be worn, as necessary. Rescue
vehicles should carry supplies such  as plastic sheeting  and disposable plastic
bags to assist in preventing spread of contamination.
Inhalation Exposure:

1.   Move victims to fresh air. Emergency personnel should avoid self-exposure
     to methyltrichlorosilane.

2.   Evaluate vital signs including pulse and  respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR. If not breathing, provide
     artificial respiration. If breathing is  labored,  administer oxygen or
     other respiratory support.

3.   Obtain authorization  and/or further instructions from the local hospital
     for  administration  of an  antidote  or performance of  other invasive
     procedures.

SECTION IX - EMERGENCY TREATMENT INFORMATION

    Signs and Symptoms of Exposure:  Inhalation of mist is highly irritating
    to mucous membranes, causing tearing, sneezing, and salivation.  Eye
    contact may result in severe irritation.  Contact of liquid with the skin
    may cause blistering and burning (*CHRIS 1978). Headaches and throat
    irritation have also been reported as a result of exposure to this compound
    (Clayton  and Clayton 1981, p. 3751).

    Emergency and First Aid Procedures: Move victim to fresh air and call
    emergency medical care. If not breathing, give artificial respiration. If
    breathing is difficult, give oxygen.  Remove and isolate contaminated
    clothing and shoes at the site. In case of contact with the material,
    immediately flush skin  or eyes with running water for at least 15 minutes.
    Speed in  removing material from the skin is of extreme importance.  Keep
    victim quiet and maintain normal body temperature.  Since effects may be
    delayed, keep victim under observation (*DOT 1984).

    Used as a chemical intermediate for quaternary ammonium salts and for
    alkylation of phenols  and thiols ("'SRI), and as a methylating agent in the
    manufacture of many organic chemicals (*Merck 1983).  Formerly, dimethyl
    sulfate was used as a  war gas. It is also used in the manufacture of dyes,
    perfumes, for the separation of mineral oils,  and for the analysis of auto
    fluids (*Browning 1965).
SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE
(Steps to be Taken in Case Material is Released or Spilled)

    If spilled in a building, the building must be evacuated  and the agent
    decomposed by hosing with water or spraying with 5 percent sodium hydroxide
    (caustic soda) (*Dreisbach 1977). For large spills, evaporating
    vapors can be collected in a chamber with a gas cleaning device
    (*NIOSH/OSHA 1981).
SECTION VIII - PROTECTIVE EQUIPMENT FOR EMERGENCY SITUATIONS

    For emergency situations, wear a positive pressure, pressure-demand,
    full facepiece self-contained breathing apparatus (SCBA) or pressure-
    demand supplied air respirator with escape SCBA and a fully-encapsulating,
    chemical resistant suit.  See the introductory information section at  the

SECTION IX   (continued)

    (later). Ingestion or direct contact with mucous membranes causes
    corrosion. Once absorbed, lung damage and liver and kidney injury will
    occur (*Dreisbach 1977).  Liquid  dermal exposure causes blistering,
    followed by convulsions, delirium, coma, and death in severe cases (*Merck
    1983).

    Emergency and First Aid Procedures: Move victim to fresh air and call
    emergency medical care.  If not breathing, start artificial respiration; if
    breathing is difficult, give oxygen.  If dermal contact occurs, immediately
    flush with water for 15 minutes.   It is very important to quickly remove
    material from skin.  Remove and isolate contaminated clothing and shoes at
    the site.  Keep victim quiet and maintain normal body temperature.  Since
    effects may  be delayed, keep  a close watch on the victim (DOT 1984, Guide
    57).

SECTION IX - EMERGENCY TREATMENT INFORMATION

    Signs and Symptoms of Exposure: Nerve agent symptoms include difficulty
    in breathing, drooling, nausea, vomiting, cramps, involuntary defecation
    and urination, twitching, jerking, staggering, headache, confusion,
    drowsiness, coma, and convulsion. Inhalation causes dimness of vision and
    pinpointing of the pupils (U.S. Army 1975, p. 3-2).

    Emergency and First Aid Procedures:  The toxic effects of tabun are
    similar to parathion (Sax 1984, p. 1335). First aid for parathion is as
    follows:  move victim to fresh air; call emergency  medical care. If not
    breathing, give artificial respiration.  If breathing is difficult, give
    oxygen. In case of contact with  material, immediately flush skin or eyes
    with running water for at least 15 minutes. Speed in removing material
    from skin is of extreme  importance.  Remove and  isolate contaminated
    clothing and shoes at the site.  Keep victim quiet and maintain normal body
    temperature.  Effects may be delayed; keep victim under observation (DOT
    1984, Guide 55).

                                   DIOXATHION

Emergency Life-Support Procedures:

Acute exposure to dioxathion may require decontamination and life support for
the victims. Emergency personnel should wear protective clothing appropriate
to the type and degree of  contamination.  Air-purifying or supplied-air
respiratory equipment should also be worn, as necessary.  Rescue vehicles
should carry supplies such as plastic sheeting and disposable plastic  bags to
assist in preventing spread of contamination.


Inhalation Exposure:

1.  Move  victims to fresh air. Emergency personnel should avoid self-exposure
     to dioxathion.

2.  Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse  is detected, provide CPR. If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

3.  Obtain authorization and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

4.  Transport to a health  care facility.
Dermal/Eye Exposure:

1.   Remove victims from exposure.  Emergency personnel should avoid self-
     exposure to dioxathion.

2.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration.  If breathing is labored, administer oxygen or
     other respiratory support.

3.   Remove contaminated clothing as soon as possible.

4.   If eye exposure has occurred, eyes must be flushed with lukewarm water for
     at least 15 minutes.

5.   Wash exposed skin area three times with soap and water.

6.   Obtain authorization and/or further instructions from the local hospital
     for administration  of an antidote or performance of other invasive
     procedures.

7.   Transport to a health care facility.

                                   DIOXATHION

Ingestion Exposure:

1.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

2.   Obtain authorization and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

3.   Vomiting  may be induced with syrup of Ipecac.  If elapsed time since
     ingestion of dioxathion is unknown or suspected to be greater than
     30 minutes, do not induce vomiting and proceed to Step  4.  Ipecac should
     not be administered to children under 6 months of age.

     Warning: Ingestion of dioxathion may result in sudden onset of seizures
     or loss of consciousness.  Syrup of Ipecac should be administered only  if
     victims are alert, have an active gag-reflex, and show no signs of
     impending seizure or coma.  If ANY uncertainty exists, proceed to Step 4.

     The following dosages of Ipecac are recommended: children up to 1 year
     old, 10 mL (1/3 oz); children 1 to 12 years old, 15 mL (1/2 oz); adults,
     30 mL (1 oz).  Ambulate (walk) the victims and give large quantities of
     water. If vomiting has not occurred after 15 minutes, Ipecac may be
     readministered.  Continue to ambulate and give water to  the victims.  If
     vomiting has not occurred  within 15 minutes after second administration of
     Ipecac, administer activated charcoal.

4.   Activated charcoal may be administered if victims are conscious and alert.
     Use 15 to 30  g (1/2 to 1 oz) for children, 50 to 100 g (1-3/4 to 3-1/2 oz)
     for adults, with 125 to 250 mL (1/2 to 1 cup) of water.

5.   Promote excretion by administering a saline cathartic or sorbitol to
     conscious and alert victims.  Children  require 15 to 30 g (1/2 to 1 oz)
     of cathartic;  50  to 100 g  (1-3/4 to 3-1/2 oz) is recommended  for adults.

6.   Transport to a health care facility.

SECTION IX - EMERGENCY TREATMENT INFORMATION

    Signs and Symptoms of Exposure:  The toxic effects are similar to
    parathion (Sax 1984, p. 1009). Symptoms of parathion poisoning include
    anorexia, nausea, vomiting, diarrhea, excessive salivation, pupillary
    constriction, bronchoconstriction, muscle twitching, convulsions, coma,
    respiratory failure. Effects are cumulative (Sax 1984, p. 2119).

    Emergency and First Aid Procedures:  Effects are similar to those of
    parathion (Sax 1984, p. 1009). First aid procedures for parathion are as
    follows:  move victim to fresh air; call emergency medical care. If not
    breathing, perform artificial respiration.  If breathing is difficult, give
    oxygen. In case of contact with material, immediately  flush skin or eyes
    with running water for at least  15 minutes.  Speed in removing  material
    from skin is of extreme importance.  Remove and isolate contaminated
    clothing and shoes  at the site. Keep victim quiet and maintain  normal body
    temperature.  Effects may be delayed; keep victim under observation (DOT
    1984, Guide 55).

                               ISOBUTYRONITRILE

Signs and symptoms of acute exposure to isobutyronitrile may include
hypertension (high blood pressure) and tachycardia (rapid heart rate),
followed by hypotension (low blood pressure) and bradycardia (slow heart rate).
Cherry-red (and potentially bloody) mucous membranes,  cardiac arrhythmias, and
other cardiac abnormalities are common. Cyanosis (blue tint to  skin and mucous
membranes) may also be found.

Tachypnea (rapid respiratory rate) may be followed by respiratory depression.
Lung hemorrhage and pulmonary edema may occur.  Headache,  vertigo (dizziness),
agitation, giddiness, salivation, nausea, and vomiting may be followed by
combative behavior, convulsions, and coma.

Isobutyronitrile is irritating to the skin and mucous membranes.  Lacrimation
(tearing) and a burning sensation of the mouth and throat are common.
Emergency Life-Support Procedures:

Acute exposure to isobutyronitrile may require decontamination and life support
for the victims.  All exposed persons should be transported to a health care
facility as quickly as possible.  Emergency personnel should wear protective
clothing appropriate to  the type and degree of contamination.  Air-purifying or
supplied-air respiratory equipment should also be worn, as necessary. Rescue
vehicles should carry supplies such as plastic sheeting and disposable plastic
bags to assist in preventing spread of contamination.
Inhalation Exposure:

1.  Move victims to fresh air.  Emergency personnel should avoid self-exposure
     to isobutyronitrile.

2.  Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration. IMMEDIATELY begin administering 100% oxygen to
     all victims.  Monitor victims for respiratory distress.

     Warning: To prevent self-poisoning, avoid mouth-to-mouth breathing; use a
     forced-oxygen mask. Direct oral contact with isobutyronitrile-
     contaminated persons or their gastric contents may result in  self-
     poisoning.

3.  RUSH to  a health care facility!

4.  Obtain authorization and/or further instructions from the  local hospital
     for administration of an antidote or performance of other invasive
     procedures.
Dermal/Eye Exposure:

1.  Remove victims from exposure.  Emergency personnel should avoid self-
     exposure to isobutyronitrile.

    1984, Guide 28).

    Unusual Fire and Explosion Hazards:  Vapors form flammable mixtures with
    air, and may travel a considerable distance to a source of ignition and
    flash back. Polymerization may take place in containers, possibly with
    violent rupture of containers (*NFPA 1978). Upon exposure to heat or
    flame, it emits toxic and irritating fumes (*Sax 1979). Container may
    explode in heat of fire. Vapor explosion and poison hazard indoors,
    outdoors, or in sewers (DOT 1984, Guide 28).

Other Limits Recommended:  NIOSH:  0.3 mg/ms 10 hr TWA (NIOSH 1987, p.46).
It is recommended that no more than 0.05 mg/kg/day be absorbed by workers
(*ACGIH  1980).  Suspected of carcinogenic potential in humans; notice of
intent to change to 0.03 mg/ms for 1985-86 (ACGIH 1985, p.  42).

    Routes of Entry:  Inhalation: Yes (NIOSH/OSHA  1978,  p. 43)
                    Skin: Yes (*Hamilton 1974)
                    Ingestion:  Yes (NIOSH/OSHA 1978, p. 43)

    Health Hazards (Acute, Delayed, and Chronic):  Classified as very toxic;
    probable oral lethal human dose is between 50 and 500 mg/kg or between. 1
    teaspoon and 1 ounce for a 150 Ib. person (Gosselin 1984, p. 11-409).
    Polymerized  acrylamide is not toxic, but the  monomer can cause peripheral
    nerve damage (*Doull 1980).  It is a cumulative neurotoxin and  repeated
    exposure to small amounts may cause serious injury to the nervous system
    (*Rumack 1975 to Present).  The neurological effects may be delayed.
    Polymer inhibitors  or stabilizers added to the monomer may also produce
    toxicity (*Peer Review Committee). The symptoms of acrylamide toxicity are
    consistent with mid-brain lesions (*Hamilton 1974) and blocked  transport
    along  both motor and sensory axons (*Doull 1980).

    Medical Conditions Generally Aggravated by Exposure:  Individuals with
    nervous system diseases should not be exposed to acrylamide (*Plunkett
    1976).

SECTION IX -- EMERGENCY TREATMENT INFORMATION

    Signs and Symptoms of Exposure: It is an irritant to the skin and is
    corrosive by ingestion or inhalation. Concentrations of 10 ppm have caused
    lachrymation and a concentration of 190 ppm for 10 minutes has been lethal
    to humans. Irritation  of the lung and  eyes may persist after cessation of
    exposure.  Skin allergies may also occur (*Clayton and Clayton  1981-82).
    After 2-3 inhalations,  brief initial irritation may occur followed by
    massive symptoms (heavy cough) after 36 hours. Relapses may  occur in
    following days with eventual full recovery (*Schuckmann 1972).

    Emergency and First Aid Procedures:  Move victim to fresh air  and call
    emergency medical care. If not breathing, give artificial respiration; if
    breathing is difficult, provide oxygen.  Remove and isolate contaminated
    clothing and shoes at the site.  In case of contact, immediately flush skin
    or eyes with water for at least 15 minutes.  Keep victim quiet and maintain
    normal body temperature.  Since effects may be delayed, keep careful watch
    on the victim (DOT 1984, Guide 28).

should carry supplies such  as plastic sheeting and disposable plastic bags to
assist in preventing spread of contamination.
Inhalation Exposure:

1.   Move victims to fresh air.  Emergency personnel should avoid self-exposure
     to diphacinone.

2.   Evaluate vital  signs including pulse and  respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration.    If  breathing is labored, administer oxygen or
     other respiratory support.

3.   Obtain authorization and/or further  instructions from the local hospital
     for  administration  of an  antidote or  performance  of other invasive
     procedures.

4.   RUSH to a health care facility.
Dermal/Eye Exposure:

1.   Remove victims from exposure.   Emergency personnel should  avoid self-
     exposure to diphacinone.

2.   Evaluate vital  signs including pulse and  respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration.   If  breathing is labored, administer oxygen or
     other respiratory support.

3.   Remove contaminated clothing as soon as possible.

4.   If eye exposure has occurred, eyes must be flushed with lukewarm water for
     at least 15 minutes.

5.   Wash exposed skin areas twice with soap and water.

6.   Obtain authorization  and/or further  instructions from the local hospital
     for  administration  of an   antidote or  performance  of other invasive
     procedures.

7.   RUSH to a health care facility.

     for  administration  of an  antidote  or  performance  of other invasive
     procedures.

3.   Vomiting may be induced with syrup  of  Ipecac.   If  elapsed  time since
     ingestion of diphacinone is unknown or suspected to be greater than
     30 minutes,  do not  induce vomiting and proceed to Step 4.  Ipecac should
     not be administered to children under 6 months of age.

     Warning:  Ingestion of diphacinone may result in sudden onset  of seizures
     or loss of consciousness.  Syrup of Ipecac should be administered only if
     victims are alert, have  an active gag-reflex, and show  no signs of
     impending seizure or coma. If ANY uncertainty  exists, proceed to Step 4.

     The following  dosages of Ipecac are recommended:  children up to 1 year
     old, 10 mL (1/3 oz); children 1 to 12 years old, 15 mL (1/2 oz); adults,
     30 mL (1 oz).  Ambulate  (walk) the victims and give large quantities of
     water. If vomiting has not  occurred  after  15  minutes,  Ipecac may be
     readministered.  Continue to  ambulate and give water to the victims. If
     vomiting has not occurred within 15 minutes after second administration of
     Ipecac, administer activated charcoal.

4.   Activated charcoal may be administered if victims are conscious and alert.
     Use 15 to  30 g (1/2 to 1 oz) for children,  50  to 100 g (1-3/4 to 3-1/2 oz)
     for adults, with  125 to 250 mL (1/2 to 1 cup) of  water.

5.   Promote  excretion  by  administering  a saline cathartic or sorbitol to
     conscious and alert victims. Children require 15 to 30 g (1/2 to 1 oz)
     of cathartic; 50 to 100 g  (1-3/4 to 3-1/2 oz) is recommended for adults.

6.   RUSH to a health care facility.

profound weakness. Vomiting, diarrhea, abdominal pain, seizures, and coma may
also occur. The heart rate may decrease following oral exposure or increase
following dermal exposure.  Chest pain may be noted.  Hypotension (low blood
pressure) may be observed, although hypertension (high blood pressure) is not
uncommon.  Respiratory symptoms include dyspnea (shortness of breath),
respiratory depression, and respiratory paralysis.  Psychosis may occur.

Emergency Life-Support Procedures:

Acute exposure to azinphos-methyl  may require decontamination and life support
for the victims.  Emergency personnel should wear protective clothing
appropriate to the type and degree  of contamination.  Air-purifying or
supplied-air respiratory equipment  should also be worn, as necessary. Rescue
vehicles should carry supplies such  as plastic sheeting and disposable plastic
bags to assist in preventing spread of contamination.


Inhalation Exposure:

1.   Move  victims to fresh air. Emergency personnel should avoid self-exposure
     to azinphos-methyl.

2.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse  is detected, provide CPR. If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

3.   Obtain authorization and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

4.   Transport to a health  care facility.
Dermal/Eye Exposure:

1.   Remove victims from exposure.  Emergency personnel should avoid self-
     exposure to azinphos-methyl.

2.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

3.   Remove contaminated clothing as soon as possible.

4.   If eye exposure has occurred, eyes must be flushed with lukewarm water for
     at least IS minutes.

5.   Wash exposed skin areas three times with soap and water.,

6.   Obtain authorization  and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

Ingestion Exposure:

1.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

2.   Obtain authorization and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

3.   Vomiting  may be induced with syrup of Ipecac. If elapsed time since
     ingestion of azinphos-methyl is unknown or suspected to  be greater  than
     30 minutes, do not induce vomiting and  proceed  to Step  4. Ipecac should
     not be administered to children under 6  months of age.

     Warning: Ingestion of azinphos-methyl may result in sudden onset of
     seizures or loss of consciousness.  Syrup of Ipecac should be
     administered only if victims are alert, have an active gag-reflex, and
     show no signs of impending seizure or coma.  If ANY uncertainty exists,
     proceed to Step 4.

     The following dosages of Ipecac are recommended: children up to  1 year
     old, 10 mL (1/3 oz);  children 1 to 12 years  old, 15 mL (1/2 oz); adults,
     30 mL (1 oz).  Ambulate (walk) the victims and give large quantities of
     water. If vomiting has not occurred after  15 minutes, Ipecac may be
     readministered.  Continue to ambulate and give water to  the victims.  If
     vomiting has not occurred within 15 minutes after second administration of
     Ipecac, administer activated charcoal.

4.   Activated charcoal may be administered if victims are conscious and alert.
     Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g  (1-3/4 to 3-1/2 oz)
     for adults, with 125  to 250 mL (1/2 to 1  cup) of water.

5.   Promote excretion  by administering a saline cathartic or sorbitol to
     conscious and alert victims. Children require 15 to 30 g (1/2 to 1 oz)
     of cathartic; 50 to 100 g (1-3/4 to 3-1/2 oz) is recommended for adults.

6.   Transport to a health care facility.

SECTION IX -- EMERGENCY TREATMENT INFORMATIC.

    Signs and Symptoms of Exposure: This is an alkyl mercu.y pesticide.
    Patients complain of headache, paresthesia of tongue, lips, fingers, and
    toes, a metallic taste in mouth, gastrointestinal disturbances, gas, and
    diarrh.ea.  Nervous system symptoms may appear first after a relatively
    slight exposure or have a latency period of several weeks. These symptoms
    include fine tremors of extended hands, loss of side vision, slight loss  of
    coordination, loss of coordination of speech, writing and gait.
    Uncoordination may progress to loss of ability to control voluntary
    movements.  Irritability and bad  temper may progress to mania.  Stupor or
    coma may develop. Blisters or dermatitis may be present on skin.  Symptoms
    persist for years even  in cases of mild exposure (Hayes 1982, pp. 20-21).

    Emergency and First Aid Procedures: This is an alkyl mercury pesticide
    (Hayes 1982, p. 20).  Move  victim to fresh air; call emergency medical
    care.  If not breathing, give artificial respiration.  If breathing is
    difficult, give oxygen. In  case of contact with material, immediately
    flush skin or eyes with running water for at least 15 minutes. Speed in
    removing material from skin is of extreme importance.  Remove and isolate
    contaminated clothing and shoes  at the site. Keep victim quiet and
    maintain normal body temperature.  Effects may be delayed; keep victim
    under observation (DOT 1984, Guide 55).

                               POTASSIUM CYANIDE

Signs and symptoms  of  acute exposure  to potassium  cyanide may  include
hypertension (high blood pressure) and tachycardia (rapid heart rate), followed
by hypotension (low blood pressure) and bradycardia (slow heart rate).  Cardiac
arrhythmias and other cardiac abnormalities are common. Cyanosis (blue tint to
the skin and mucous membranes), and cherry-red or  bloody mucous  membranes may
appear.

Tachypnea (rapid  respiratory rate)  may be followed by respiratory depression.
Lung hemorrhage and pulmonary edema may occur.   Headache, vertigo (dizziness),
agitation,  and  giddiness  may  precede  combative  behavior, convulsions,
paralysis, protruding eyeballs, dilated and unreactive pupils, and coma.
Potassium cyanide is  irritating  to the  skin, eyes, and mucous membranes.
Lacrimation  (tearing) and a  burning  sensation  of the mouth and throat are
common. Salivation, nausea, and vomiting may also occur.
Emergency Life-Support Procedures:

Acute exposure  to  potassium  cyanide may  require  decontamination  and life
support for the victims. All exposed persons should be transported to a health
care facility  as quickly  as  possible.   Emergency  personnel should wear
protective clothing  appropriate to the type and degree of contamination. Air-
purifying  or  supplied-air respiratory equipment should  also  be worn, as
necessary.  Rescue  vehicles should  carry supplies such as plastic sheeting and
disposable plastic bags to assist in preventing spread of contamination.
Inhalation Exposure:

1.   Move victims to fresh air.  Emergency personnel should avoid self-exposure
     to potassium cyanide.

2.   Evaluate vital  signs including  pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not  breathing, provide
     artificial respiration.  IMMEDIATELY  begin administering  100% oxygen to
     all  victims.  Monitor victims for respiratory distress.

     Warning:  To prevent self-poisoning,  avoid mouth-to-mouth breathing; use a
     forced-oxygen mask.    Direct  oral contact  with  potassium  cyanide-
     contaminated  persons or  their gastric  contents can  result  in self-
     poisoning.

3.   RUSH to a health care facility!

4.   Obtain authorization  and/or further instructions from the local hospital
     for  administration  of  an  antidote or performance of  other invasive
     procedures.

                    Ingestion:  Yes (Weiss 1980, p. 443)

    Health Hazards (Acute, Delayed, and Chronic):  Ethyleneimine is classified
    as extremely toxic with a probable oral lethal dose of 5-50 mg/kg which is
    approximately 7 drops to 1 teaspoonful for a 70 kg (150 Ib.) person
    (*Gosselin 1976). Ethyleneimine gives  inadequate warning when
    over-exposure is by inhalation or skin absorption. It is a severe
    blistering agent, causing third degree chemical burns of the skin.  Also,
    it has a corrosive effect on mucous membranes and may cause scarring of the
    esophagus. It is corrosive to eye tissue and may cause permanent corneal
    opacity and conjunctival scarring  (Weiss 1980, p. 443).  Severe exposure
    may result in overwhelming pulmonary edema.  Renal damage has been
    described (Gosselin 1984, p. H-207).  Hemorrhagic congestion of all
    internal organs has been observed (Clayton and Clayton 1981-82, p. 2674).

SECTION IV   (continued)

    Unusual Fire and Explosion Hazards:  Irritating vapors  are generated when
    heated.  Vapor is heavier than air and may travel a considerable distance
    to a source of ignition and flash back.  May polymerize in fires with
    evolution of heat and container rupture (Weiss 1980, p. 443).  Runoff to
    sewer may  create fire or explosion hazard (DOT 1984, Guide 30).
    Ethyleneimine vapors are not inhibited and may form polymers in vents or
    flame arresters, r , alting in stopping of the vents (*NFPA  1978).

Emergency Life-Support Procedures:

Acute exposure to OMPA may require decontamination  and life support for the
victims.  Emergency personnel should wear protective clothing appropriate to
the type  and degree of contamination.  Air-purifying or supplied-air
respiratory equipment should also be worn, as necessary.  Rescue vehicles
should carry supplies such as plastic sheeting and disposable plastic bags to
assist in  preventing spread of contamination.


Inhalation Exposure:

1.   Move victims to fresh air. Emergency personnel should avoid self-exposure
     to OMPA.

2.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration.  If breathing is labored, administer oxygen or
     other respiratory support.

3.   Obtain authorization and/or further instructions from the local hospital
     for administration of an antidote or performance  of other invasive
     procedures.

4.   Transport to a health care facility.
Dermal/Eye Exposure:

1.  Remove victims from exposure.  Emergency personnel should avoid self-
     exposure to OMPA.

2.  Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

3.  Remove contaminated clothing as soon as possible.

4.  If  eye exposure has occurred, eyes must be flushed with lukewarm water for
     at least 15 minutes.

5.  Wash exposed skin areas  three times with soap and water.

6.  Obtain authorization  and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

7.  Transport to a  health care facility.

Ingestion Exposure:

1.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR. If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

2.   Obtain authorization and/or further instructions  from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

3.   Vomiting  may be induced with syrup of Ipecac.   If elapsed time since
     ingestion of OMPA is unknown or suspected to be greater than 30 minutes,
     do not induce vomiting and proceed to Step 4.  Ipecac should  not be
     administered to  children under 6 months of age.

     Warning:  Ingestion of OMPA may result in sudden onset of seizures or loss
     of consciousness.  Syrup of Ipecac should be administered only if victims
     are alert, have an active gag-reflex, and show no signs of impending
     seizure or coma.  If ANY uncertainty exists, proceed to Step 4.

     The following dosages  of Ipecac are recommended:  children up to  1 year
     old, 10 mL (1/3  oz); children 1 to 12 years old, 15 mL (1/2 oz); adults,
     30 mL (1 oz).  Ambulate (walk) the victims  and  give large quantities of
     water. If vomiting has not occurred after  15 minutes, Ipecac  may be
     readministered.  Continue to ambulate and give  water to the victims.  If
     vomiting has not occurred within 15 minutes after  second administration of
     Ipecac, administer activated charcoal.

4.   Activated charcoal may be administered if victims are conscious and alert.
     Use 15 to 30 g (1/2 to  1 oz)  for children, 50  to 100 g (1-3/4 to 3-1/2 oz)
     for adults, with  125 to 250 mL (1/2 to 1  cup) of water.

5.   Promote excretion by administering a saline cathartic or sorbitol to
     conscious and alert victims.  Children require 15 to 30 g (1/2  to 1 oz)
     of cathartic; 50  to 100  g (1-3/4 to 3-1/2 oz)  is recommended for adults.

6.   Transport to a health care facility.

Emergency Life-Support Procedures:

Acute exposure to parathion-methyl may require decontamination and life support
for the victims.  Emergency personnel should wear protective clothing
appropriate to the type and degree  of contamination.  Air-purifying or
supplied-air respiratory equipment should also be worn, as necessary.  Rescue
vehicles should carry supplies such  as plastic sheeting and disposable plastic
bags to assist in preventing spread of contamination.


Inhalation Exposure:

1.   Move  victims to fresh air. Emergency personnel should avoid self-exposure
     to parathion-methyl.

2.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse  is detected, provide CPR. If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

3.   Obtain authorization and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

4.   Transport to a health  care facility.


Dermal/Eye Exposure:

1.   Remove victims from exposure.  Emergency personnel should avoid self-
     exposure to parathion-methyl.

2.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR. If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

3.   Remove contaminated  clothing  as soon as possible.

4.   If eye exposure has occurred, eyes must be  flushed with lukewarm water for
     at least 15 minutes.

5.   Wash  exposed skin areas three times with soap and water.

6.   Obtain authorization and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

7.   Transport to  a health care facility.

Ingestion Exposure:

J.  Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR. If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

2.  Obtain authorization and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

3.  Vomiting  may be induced with syrup of Ipecac.  If elapsed time since
     ingestion of parathion-methyl is unknown or  suspected to be greater than
     30 minutes, do not induce  vomiting and  proceed to Step  4.  Ipecac should
     not be administered to children under 6  months of age.

     Warning: Ingestion of parathion-methyl may result in sudden onset of
     seizures or loss of consciousness. Syrup of Ipecac should be
     administered only if victims are alert, have an active gag-reflex, and
     show no signs of impending seizure or coma.  If ANY uncertainty exists,
     proceed to Step 4.

     The following dosages of Ipecac are recommended: children up to  1 year
     old, 10 mL (1/3  oz); children 1 to 12 years old, 15 mL (1/2 oz); adults,
     30 mL (1 oz).  Ambulate (walk) the victims and give large quantities of
     water. If vomiting has not occurred after 15  minutes, Ipecac may be
     readministered.  Continue  to ambulate and give water to  the victims.  If
     vomiting has not occurred  within 15 minutes  after second administration of
     Ipecac, administer activated charcoal.

4.  Activated charcoal may be administered if victims are conscious and alert.
     Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g  (1-3/4 to 3-1/2 oz)
     for adults, with 125 to 250 mL (1/2 to 1  cup)  of water.

5.  Promote excretion by administering a saline cathartic or sorbitol to
     conscious and alert victims.  Children require 15 to 30 g (1/2 to 1 oz)
     of cathartic; 50  to 100 g (1-3/4 to 3-1/2 oz) is recommended for adults.

6.  Transport to a health care facility.

Emergency Life-Support Procedures:

Acute exposure to phorate may require decontamination and life support for the
victims.  Emergency personnel should wear protective clothing appropriate to
the type and degree of contamination. Air-purifying or supplied-air
respiratory equipment should also be  worn, as necessary.  Rescue vehicles
should carry supplies such as plastic sheeting and disposable plastic bags to
assist in preventing spread of contamination.


Inhalation Exposure:

1.   Move victims to fresh air. Emergency personnel should avoid self-exposure
     to phorate.

2.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR. If not breathing, provide
     artificial respiration.  If breathing is labored, administer oxygen or
     other respiratory support.

3.   Obtain authorization and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

4.   Transport to a health care facility.
Dermal/Eye Exposure:

1.   Remove victims from exposure.  Emergency personnel should avoid self-
     exposure to phorate.

2.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

3.   Remove contaminated clothing as soon as possible.

4.   If eye exposure has occurred, eyes must be flushed with lukewarm water for
     at least 15 minutes.

Ingestion Exposure:

1.   Evaluate vital signs including pulse and respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR. If not breathing, provide
     artificial respiration. If breathing is labored, administer oxygen or
     other respiratory support.

2.   Obtain authorization  and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

3.   Vomiting may be induced with syrup of Ipecac.  If elapsed time since
     ingestion of phorate is unknown or suspected to be greater than
     30 minutes, do not induce  vomiting and proceed to Step 4.  Ipecac should
     not be administered to children under 6 months of age.

     Warning: Ingestion of phorate may result in .sudden onset of seizures or
     loss of consciousness.  Syrup of Ipecac should be administered only if
     victims are alert, have an active gag-reflex, and show no signs of
     impending seizure or coma.  If ANY uncertainty exists, proceed to Step 4.

     The following dosages of Ipecac are recommended:  children up to 1 year
     old, 10 mL (1/3 oz); children 1 to 12 years old, 15 mL (1/2 oz); adults,
     30 mL (1 oz).  Ambulate (walk) the victims and give large quantities of
     water. If vomiting has not occurred after 15 minutes, Ipecac may be
     readministered.  Continue  to ambulate and give water to  the victims.  If
     vomiting has not occurred within 15 minutes after second administration of
     Ipecac, administer activated charcoal.

4.   Activated charcoal may be administered if victims are conscious and alert.
     Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g (1-3/4 to 3-1/2 oz)
     for adults, with 125 to 250 mL (1/2 to 1 cup) of water.

5.   Promote excretion by administering a saline  cathartic or sorbitol to
     conscious and alert victims. Children  require 15 to 30 g (1/2 to 1 oz)
     of cathartic; 50  to 100 g (1-3/4 to 3-1/2 oz) is recommended for adults.

6.   Transport to a health care facility.

     other respiratory support.

2.   Obtain authorization and/or further instructions from the local hospital
     for administration of an antidote or performance of other invasive
     procedures.

3.   Vomiting  may be induced with syrup of Ipecac.  If elapsed time since
     ingestion of disulfoton  is unknown or suspected to be greater than
     30 minutes,  do not induce vomiting and proceed to Step 4.  Ipecac should
     not be administered to children under 6 months of age.

     Warning: Ingestion of disulfoton may result in sudden onset of seizures
     or loss of consciousness.  Syrup of Ipecac should be administered only if
     victims are alert, have an active gag-reflex, and show no signs of
     impending seizure or coma.  If ANY uncertainty exists, proceed to Step 4.

     The following dosages of  Ipecac are recommended:  children up to 1 year
     old, 10 mL (1/3 oz); children  1 to 12 years old,  15 mL (1/2 oz); adults,
     30 mL (1 oz).  Ambulate (walk) the victims and give large quantities of
     water. If vomiting has not occurred after 15 minutes, Ipecac may be
     readministered.  Continue to ambulate and give water to  the victims. If
     vomiting has not occurred within 15 minutes after second administration of
     Ipecac, administer activated charcoal.

4.   Activated charcoal may be administered if victims are conscious and alert.
     Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g (1-3/4 to 3-1/2 oz)
     for adults, with 125 to 250 mL (1/2 to 1 cup) of water.

5.   Promote excretion by administering a saline cathartic or sorbitol to
     conscious and alert victims. Children require 15 to 30 g (1/2 to 1 oz)
     of cathartic; 50  to 100 g (1-3/4 to 3-1/2 oz) is recommended  for adults.

6.   Transport to a health care facility.

                                   HYDRAZINE

Signs and symptoms of  acute exposure  to hydrazine may include severe eye
irritation,  facial numbness, facial  swelling, and  increased salivation.
Hydrazine vapor  may  immediately  irritate the nose  and throat. Headache,
twitching, seizures, convulsions, and  coma may  also occur.  Gastrointestinal
signs and  symptoms include anorexia, nausea, and vomiting. Pulmonary edema and
hypotension (low blood pressure) are common. Hydrazine is toxic  to the liver,
ruptures red  blood cells,  and may  cause kidney  damage.  Dermal contact may
result in irritation or severe burns.
Emergency Life-Support Procedures:

Acute exposure to hydrazine  may require  decontamination and  life support for
the victims.  Emergency personnel should wear protective clothing appropriate
to the  type and degree of  contamination.   Air-purifying  or supplied-air
respiratory  equipment  should  also be  worn, as necessary.  Rescue vehicles
should carry supplies such as plastic sheeting and  disposable plastic  bags to
assist in preventing spread of contamination.
Inhalation Exposure:

1.   Move  victims to fresh air. Emergency personnel should avoid self-exposure
     to hydrazine.

2.   Evaluate vital signs including  pulse and respiratory rate,  and note any
     trauma.  If no pulse is  detected, provide CPR. If not breathing, provide
     artificial respiration.  If breathing  is  labored,  administer  oxygen or
     other respiratory support.

3.   Obtain authorization  and/or further instructions from the local hospital
     for  administration of  an  antidote  or performance  of  other invasive
     procedures.

4.   Transport to a health care facility.
Dermal/Eye Exposure:

Emergency Life-Support Procedures:

Acute exposure to aldrin may require decontamination and life support  for the
victims.   Emergency personnel  should  wear protective clothing appropriate to
the type  and  degree   of  contamination.    Air-purifying  or  supplied-air
respiratory  equipment  should  also be worn, as necessary.  Rescue vehicles
should carry supplies such  as plastic sheeting and  disposable plastic  bags to
assist in preventing spread of contamination.


Inhalation Exposure:

1.   Move  victims to fresh air.  Emergency personnel should avoid self-exposure
     to aldrin.

2.   Evaluate vital signs including pulse and  respiratory rate, and note any
     trauma.  If no pulse  is detected, provide  CPR.  If not breathing, provide
     artificial respiration.  If breathing is  labored,  administer  oxygen or
     other respiratory support.

3.   Obtain authorization  and/or further instructions from the local hospital
     for  administration of an antidote  or  performance  of other invasive
     procedures.

4.   Transport to a health care facility.
Dermal/Eye Exposure:

1.   Remove  victims  from  exposure.    Emergency personnel should avoid self-
     exposure to aldrin.

2.   Evaluate vital signs including pulse and  respiratory rate,  and note any
     trauma.  If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration.  If breathing is labored, administer  oxygen or
     other respiratory support.

3.   Remove contaminated clothing as soon as possible.

4.   If eye exposure has occurred, eyes must be flushed with lukewarm water for
     at least 15  minutes.

5.   Wash exposed skin areas three times.  Wash initially  with soap and  water,
     follow with an alcohol wash, then again with soap  and water.

6.   Obtain authorization  and/or further  instructions from the local hospital
     for  administration  of an  antidote or  performance  of other invasive
     procedures.

Ingestion Exposure:

1.   Evaluate vital  signs including pulse and  respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR. If not  breathing, provide
     artificial respiration.   If  breathing is labored, administer oxygen or
     other respiratory support.

2.   Obtain authorization and/or further  instructions from the local hospital
     for administration  of an  antidote or  performance  of other invasive
     procedures.

3.   Vomiting  may be induced with syrup  of  Ipecac.    If  elapsed  time since
     ingestion of aldrin is unknown or suspected to be greater than 30 minutes,
     do not induce vomiting and proceed  to  Step  4.   Ipecac should  not be
     administered to children under 6 months of age.

     Warning: Ingestion of aldrin may result in sudden onset of seizures or
     loss of consciousness.   Syrup  of  Ipecac should  be administered  only if
     victims  are  alert, have an  active  gag-reflex, and  show no signs of
     impending seizure or coma. If ANY uncertainty exists, proceed to Step 4.

     The following dosages of  Ipecac are  recommended:  children up  to 1 year
     old, 10  mL (1/3  oz); children 1 to 12 years old, 15 mL (1/2 oz); adults,
     30 mL (1 oz).  Ambulate (walk) the  victims and give large  quantities of
     water.   If  vomiting  has not  occurred after 15 minutes, Ipecac may be
     readministered.  Continue to ambulate and give water to the  victims. If
     vomiting has not occurred within 15  minutes  after second administration of
     Ipecac, administer activated  charcoal.

4.   Activated charcoal may be administered if victims are conscious and alert.
     Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g (1-3/4 to 3-1/2 oz)
     for adults, with 125  to 250 mL (1/2 to 1  cup) of water.

5.   Promote excretion by  administering  a saline  cathartic  or sorbitol to
     conscious and alert victims.  Children require 15 to 30 g (1/2 to 1 oz)
     of cathartic; 50 to 100 g (1-3/4 to 3-1/2 oz) is recommended for adults.

6.   Transport to a health  care facility.

    syndrome is similar to influenza.  High dosage may cause toxic psychosis
    similar to alcoholism.  Exposures may be misdiagnosed as asthma and heart
    failure (*Rumack 1975 to Present).

    Emergency and First Aid Procedures: (Non-Specific -- Organophosphate
    Pesticide, Liquid, n.o.s.) Move victim to fresh air; call emergency
    medical care.  If not breathing,  give artificial respiration.  If breathing
    is difficult, give oxygen.  In case of contact with material, immediately
    flush skin or  eyes with running water for at least 15 minutes. Speed in
    removing material from skin is  of extreme importance. Remove and isolate
    contaminated clothing and shoes at the site. Keep victim quiet and
    maintain normal body temperature.  Effects may be delayed; keep victim
    under observation (DOT 1984, Guide 55).

SECTION IX   (continued)

    Emergency and First Aid Procedures: Acute poisoning should be treated
    like poisoning by fluoroacetate. Ethylene fluorbhydrin (2-fluoroethanol)
    is listed among the organic fluorine derivatives of fluoroacetic acid
    (Hayes 1982, p. 501). The emergency procedures for f luoroacetic acid are:
    move  victim to fresh air; call emergency medical care.  If not breathing,
    give artificial respiration.  If breathing is difficult, give oxygen.  In
    case of contact with material, immediately flush skin or eyes with running
    water for  at least 15 minutes.  Remove and  isolate contaminated clothing
    and shoes  at the site. Keep victim quiet and maintain normal body
    temperature.  Effects may  be delayed; keep  victim under observation (DOT
    1984,  Guide  59).

SECTION VI -- USE INFORMATION

    The major uses of the ergot alkaloids fall into two categories:
    applications in obstetrics and treatment of migraine headaches (Oilman
    1985, p. 937).
SECTION VII -- PRECAUTIONS FOR SAFE HANDLING AND USE
(Steps to be Taken in Case Material is Released or Spilled)

    (Non-Specific  Alkaloid, n.o.s.)  Keep unnecessary people away; isolate
    hazard area and deny entry. Stay upwind; keep out of low areas.
    Do not touch  spilled material; stop leak if you can do so without risk.
    Use water vapor to reduce vapors.  Absorb spills with sand or other
    noncombustible absorbent material.  Small dry spills: with clean shovel
    place material into clean, dry container and cover; move containers from
    spill area.  For large spills, dike far ahead of spill for later
    disposal (DOT 1984, Guide 55).
SECTION VIII -- PROTECTIVE EQUIPMENT FOR EMERGENCY SITUATIONS

    For emergency situations, wear a positive pressure, pressure-demand,
    full facepiece self-contained breathing apparatus (SCBA) or pressure-
    demand supplied air respirator with escape SCBA and a fully-encapsulating,
    chemical resistant suit. See the introductory information section at the
    beginning of the profiles for additional information.
SECTION IX - EMERGENCY TREATMENT INFORMATION

    Signs and Symptoms of Exposure:  Nausea and vomiting occur in some
    patients after oral administration. Weakness in the legs is common and
    muscle pains in the extremities may occur.  Numbness and tingling of the
    fingers and toes may also occur (Oilman 1985, p. 938).

    Emergency and First Aid Procedures:  (Non-Specific -- Alkaloid, n.o.s.)
    Move victim to fresh air; call emergency medical care.  If not breathing,
    give artificial  respiration.  If breathing is difficult, give oxygen.  In
    case of contact with material, immediately  flush skin or eyes with running
    water for at least 15 minutes. Speed in removing material from skin is of
    extreme importance.  Remove and isolate contaminated clothing and shoes at
    the site.  Keep victim quiet and maintain normal body  temperature. Effects
    may be delayed; keep victim under observation (DOT 1984, Guide 55).

SECTION IX - EMERGENCY TREATMENT INFORMATION

    Signs and Symptoms of Exposure: As a cyanide,  massive doses may produce,
    without warning, sudden loss of consciousness and prompt death from
    respiratory arrest. Smaller but still lethal doses result in illness that
    may be prolonged for 1 or more hours.  Other symptoms may include numbness
    in throat, salivation, nausea, anxiety, dizziness, irregular breathing,
    odor of bitter almonds may be noted  on  breath, blood pressure may rise,
    slowing of the heart beat, sensation of constriction in the chest,
    unconsciousness followed by violent convulsions and  paralysis (*Gosselin
    1976).

    Emergency and First Aid Procedures: (Non-Specific -- Cyanide, Inorganic,
    n.o.s.) Move victim to fresh  air; call emergency medical care.  If not
    breathing, give artificial respiration.  If breathing is difficult, give
    oxygen.  In case  of contact with material, immediately flush skin or eyes
    with running water for at least 15 minutes. Speed in removing material
    from skin is of extreme  importance.  Remove and isolate contaminated
    clothing and shoes at the site.  Keep victim quiet and maintain normal body
    temperature.  Effects may be delayed; keep victim under observation (DOT
    1984, Guide 55).

                               CYANOGEN BROMIDE

Headache,  vertigo  (dizziness), agitation,  and  giddiness may be followed by
combative behavior, convulsions, paralysis,  protruding  eyeballs, dilated and
unreactive  pupils,  and  coma.   Tachypnea (rapid,  shallow  respirations) or
hyperpnea (rapid, deep respirations) may be followed by respiratory depression.
Lung hemorrhage and pulmonary edema may also occur.

Cyanogen bromide is irritating  to  the  skin,  eyes,  and mucous membranes.
Lacrimation (tearing) and a burning  sensation of  the   mouth  and throat are
common. Salivation, nausea, and vomiting may also occur.
Emergency Life-Support Procedures:

Acute exposure to cyanogen bromide may require decontamination and life support
for the victims.  All exposed persons should  be transported to a health care
facility as quickly as  possible.   Emergency personnel should wear protective
clothing appropriate to the type  and degree of contamination. Air-purifying or
supplied-air respiratory equipment should  also be worn, as necessary.  Rescue
vehicles should carry supplies  such as plastic sheeting  and disposable plastic
bags to assist in preventing spread of contamination.


Inhalation Exposure:

1.  Move  victims to fresh air.  Emergency personnel should avoid self-exposure
     to cyanogen bromide.

2.  Evaluate vital signs including  pulse and  respiratory rate, and note any
     trauma.  If no pulse is detected, provide CPR. If not breathing, provide
     artificial respiration.  IMMEDIATELY  begin administering  100% oxygen to
     all victims.  Monitor victims for respiratory distress.

     Warning:  To prevent self-poisoning, avoid mouth-to-mouth breathing; use
     a  forced-oxygen  mask.   Direct  oral contact with  cyanogen  bromide-
     contaminated  persons or their gastric  contents  can  result  in self-
     poisoning.

3.  RUSH to a health care facility!

4.  Obtain authorization  and/or further  instructions from the local hospital
     for  administration  of an  antidote or performance  of  other invasive
     procedures.
Dermal/Eye Exposure:

1.  Remove  victims  from  exposure.   Emergency personnel should avoid self-
     exposure to cyanogen bromide.

2.  Evaluate vital signs including  pulse and  respiratory rate,  and note any
     trauma.   If no pulse is detected, provide CPR.  If not breathing, provide
     artificial respiration.  IMMEDIATELY  begin : , -   ristering  100% oxygen to
