      1.  Environmental Health  Effects Research
      2.  Environmental Protection Technology
      3.  Ecological Research
      4.  Environmental Monitoring
      5.  Socioeconomic Environmental Studies
      6.  Scientific and Technical Assessment Reports (STAR)
      7.  Interagency Energy-Environment Research and Development
      8.  "Special" Reports
      9.  Miscellaneous Reports

This report has  been assigned  to the  ENVIRONMENTAL PROTECTION TECH-
NOLOGY series. This series describes research performed to develop and dem-
onstrate instrumentation, equipment, and methodology to repair or prevent en-
vironmental degradation from point and non-point sources of pollution. This work
provides the new or improved technology required for the control and treatment
of pollution sources to meet environmental quality standards.

                                    FOREWORD


The  U.S.  Environmental Protection Agency was created because of  increasing public
and  government concern about the dangers of  pollution to the  health and  welfare  of
the American people.  Noxious air, foul water,  and spoiled land  are tragic testimonies
to the deterioration of our natural environment. The complexity of that environment
and  the interplay of its components require a  concentrated and integrated attack  on
the problem.

Research  and development is that  necessary first step in problem solution;  it involves
defining the problem, measuring its impact, and  searching for solutions.  The Municipal
Environmental Research Laboratory develops new and improved technology and systems
to prevent,  treat, and  manage wastewater  and solid  and hazardous  waste pollutant
discharges from  municipal and  community sources, to  preserve and treat public drinking
water  supplies,  and to  minimize the adverse economic,  social,  health,  and aesthetic
effects of pollution.  This  publication is  one  of the  products  of  that  research and
provides   a  most   vital  communication  link  between  the  researcher and  the  user
community.

This study involved the  development of a  method for determining the compatibility  of
binary combinations of  hazardous  wastes.   A literature study was  conducted of  case
histories  of  accidents caused  by the combinations of  incompatible  wastes, industrial
wastestream  constitutents,  hazardous  chemical data,  and basic chemical  reactions.
Based  on  this study,  the compatibility method was developed.

The  method  consists of a  step-by-step compatibility analysis procedure and a  com-
patiblity chart.   The chart  is the  key element  in the use of the method.  Wastes  to
be mixed  or combined are first subjected, through the compatibility analysis  procedure,
to identification and  classification,  and the chart is  used to predict the  compatibility
of the wastes on  mixing.

The  method will be useful in the regulation and management  of  hazardous wastes.  It
finds its  usefulness most in determining the  types of  wastes that  may  be mixed for
economic  gains and in predicting adverse reaction consequences that  can inflict damage
to life, property,  and the environment.

      The enactment of the Resource Conservation and Recovery Act of  1976 was  in
response to the  increasing attack upon the nation's environment by the ever-expanding
volume  of hazardous wastes  that are disposed of to  the  land.  This legislation has
charged  the U.S. Environmental  Protection  Agency  (EPA) with the  responsibility  of
setting up a total management system for hazardous wastes with the goal of minimizing
the impact of these wastes upon the public health  and the environment  and on the
conservation of  national material and energy resources.

      The development of such a management system requires extensive  information
on  waste  producing  processes,  waste chemical compositions,  and  physical/chemical
characteristics,  as well  as the best available recovery and disposal technologies.  There
are many ways in which hazardous wastes may inflict damage to public health and the
environment.  These are long-term contamination of ground and surface water, pollution
of the air  by volatile materials and dusts, and extensive contamination of usable land.
However, one of the more immediate and disastrous impacts results when waste products
undergo  violent  and  toxin-producting chemical reactions  which kill or maim humans
and/or destroy  property.  These reactions  most often  occur because waste handlers
have either an inadequate  knowledge of  chemical compositions or of  how the chemical
components of different  waste types interact.  The objectives  of this report are  to:

       1)     Present the  chemical  reactions  that  are likely  to  produce  significant
             hazards to waste handlers  and the environment.

      2)     Present a listing of  chemical classes based on molecular structure and
             chemical reactivity that typically occur in wastes.

      3)     Provide guidelines for estimating which chemical classes  occur in specific
             wastestreams.

      ^)     Provide a  method for estimating the potential consequences of  mixing  of
             different classes of  wastes.

      The  best  available knowledge  of wastestream  composition, chemical thermo-
dynamics, and reaction  consequences was used to prepare the report.  However,  during
its  preparation,   the authors became  aware  of many  areas where existing knowledge
was inadequate  to make reasonably valid determinations.  These areas of poor data  or
background  information are noted  wherever possible in the report.

      This  document should  be considered an interim  report  on  the study of  waste
interaction.  The authors,  with  the support  of the  EPA, have begun actual laboratory
investigations of waste  compositions and of  interactions  between real wastestreams,
and subsequently a final  report will  be  prepared.

-------
       It is the authors' sincere hope that  those in  the  waste management industry as
well as the waste regulatory agencies, will find this report useful in reducing the risk
to the  public health and  the environment in the handling, processing, treatment, and
disposal of hazardous wastes.

                                     ABSTRACT


      This  report  describes  a method  for  determining the compatibility of binary
combinations of hazardous  wastes.   The method consists of  two main parts,  namely:
1)  the step-by-step compatibility analysis  procedures, and  2)   the  hazardous wastes
compatibility chart.  The key element  in the use of the method is  the  compatibility
chart.  Wastes  to be combined are first  subjected through the compatibility procedures
for identification and classification, and the chart is used to predict  the  compatibility
of the wastes on mixing.

      The chart consists of 41  reactivity groupings of hazardous wastes designated by
Reactivity Group Numbers  (RGN).  The RGN are displayed in binary combinations on
the chart, and the compatibility of the combinations are  designated by Reaction Codes
(RC).

      The  method  is  applicable to  four  categories of  wastes  based  on available
compositional information:  1)  compositions  known specifically, 2)  compositions known
nonspecifically by chemical classes or reactivities, 3) compositions known nonspecifically
by common or  generic names of wastes, 4)   compositions unknown requiring chemical
analysis.

      The report is intended for use in many aspects  of  the  management of hazardous
wastes.   The compatibility information that it provides can be used to determine which
wastes can  or  can  not  be mixed for economic purposes  or to prevent or minimize
adverse reaction  consequences.

      The report  is the result of  a literature  study of  case  histories  of accidents
caused by the combinations of incompatible wastes, industrial wastestream constituents
and hazardous  chemical  data, and basic chemical reactions.

      This report is submitted in partial  fulfillment of Research Grant No. R804692010
by the Hazardous Materials Management Section and the Hazardous Materials Laboratory
of the California Department of Health Services  under the sponsorship of the Municipal
Environmental Research Laboratory of the U.S. Environmental Protection Agency.  This
report  covers  a  period from September,  1976  to  September,  1978,  and work  was
completed as of September, 1978.

                                     SECTION 1


                                   INTRODUCTION
       The  Resource  Recovery  and  Conservation  Act  of  1976  (PI 94-580)  defines
hazardous waste as  solid waste or a combination  of  solid wastes which  because of its
quantity, concentration, or physical, chemical, or infectious characteristics may cause
or contribute  to  an increase in mortality or  an increase  in serious  irreversible, or
incapacitating  reversible illness;  or pose a substantial  present  or  potential hazard to
human  health  or the  environment when  improperly treated,  stored,  transported, or
disposed of, or otherwise managed.  The law also  defines solid waste to  mean not  only
solids  but also liquids, semisolids, and  contained  gaseous materials.

       The "combination of solid wastes" part  of the  definition often presents problems
in many aspects  of the  management  of  hazardous wastes.   In  some  instances, the
combination or mixture of two  or more types of the  wastes  produces  undesirable or
uncontrolled reactions  resulting  in  adverse consequences.  These reactions may cause
any one or more of the following: 1) heat generation, 2)  fire, 3) explosion, 4)  formation
of toxic fumes, 5) formation of flammable gases, 6) volatilization of toxic or flammable
substances,  7)  formation of substances of  greater toxicity,  8) formation of  shock and
friction sensitive  compounds,  9)  pressurization in closed vessels, 10)  solubilization of
toxic  substances, 11)  dispersal  of  toxic dusts, mists,  and  particles, and  12)  violent
polymerization.  In  this  report,  such  reactions are  called incompatible  reactions and
the reacting wastes are called incompatible wastes.

       In the review  of  the  literature  and surveys of  hazardous  waste management
practices,  several adverse reaction  consequences  resulting from  the  mixing of in-
compatible  hazardous wastes have been noted.  These consequences  have caused serious
accidents  involving extensive  damage to property, equipment,  vegetation, and environ-
ment  and/or injury  or death  to man,and  other  living things.   Analysis of  the case
histories of the accidents (Appendix  5) indicates that  such  accidents  resulted  from
three  primary  causes.

       The first primary cause is the  insufficiency or inaccuracy of information about
the  wastes (Appendix 5,  Case  History  (CH)  Nos.   2,5,6,7,9,11,12,16,18,19,21,22).
Hazardous  wastes are  often complex  mixtures of chemicals.   To define them  usually
requires laboratory  analysis which  is  expensive and  thus often not performed.   Waste
generators may not maintain adequate records of the  components of  their wastestreams.
In some cases,  information about  certain wastestreams are deleted or altered to reduce
the cost of  disposal.   Still, in some  instances, the  properties of  some  wastes  change
with time  and temperature, potentially producing more hazardous and  unknown  com-
ponents.  Persons handling the wastes  often are ignorant of or  pay little attention to
the inherent hazardous properties of  the wastes.

                                          1

-------
       The  second primary  cause of  the  accidents is  indiscriminate handling of  the
wastes.  Often supposedly empty containers actually  contain  hazardous residues that
result in adverse consequences when reused (CH Nos. 2, 20, 21, 23).  Haulers uninformed
of hazardous chemical interactions often top off their loads on the way  to the disposal
sites, initiating violent reactions  that often result in disastrous consequences (CH Nos.
1, 23).  Clandestine transfers  of  wastes into disposal sites without attendant operators
have  resulted  in accidents  (CH  No.  9).   Rough  handling of  waste containers  have
resulted in the rupture or leakage of highly reactive materials (CH No. 16).  Inadvertent
mixing  of  two or more  types of incompatible wastes  in  one vessel have resulted in
hazardous consequences (CH No. 10).  Uncontrolled reactions have been known to  result
from  inadequately designed chemical treatment processes for purposes of detoxification
or resource recovery  (CH No.  22).

       The  third  primary  cause of the accidents is indiscriminate disposal  practices.
Incompatible bulk wastes  have been  indiscriminately mixed at disposal sites.  Wastes
that  are incompatible with  the composition of the disposal areas  have been noted at
disposal sites such as  sanitary landfills, mine openings, injection wells, and burial  cells
(CH Nos. 3, 4,  7, 15).  Often the inexpensive  or unwanted containers used  to  contain
wastes  for  disposal readily  rupture  or leak (CH Nos. 13,  24).  Containerized wastes
irrespective of contents often are co-disposed  and hazardous reactions result when the
containers rupture or  leak because of  corrosion and the wastes mix  (CH Nos. 7, 8, 9,
14).

       The  method of determining waste compatibilities  described in this report was
developed on the principal assumption that wastes interactions are due to the reactions
produced by the pure chemicals  in the  wastes.   Included in  this assumption  is  the
condition that  the chemicals react at ambient  temperature and  pressure and  that their
reactivities are uninfluenced by concentration,  synergistic and antagonistic effects.  In
this  assumption, the compatibility of  a combination of wastes  can  be predicted by the
reactivities of the chemical  constituents  in  the respective wastes.

       Available data indicate that hazardous wastes  are ill-defined and  consist  of
complex mixtures generated  by a great variety  of  sources.  No two types  of wastes
appear  to  be  identical.   Even a single process  appears to produce different types  of
wastes.  Laboratory analyses of wastes seem  to be non-existent or very cursory because
of high costs and the  complexity of  required analytical methods.   Characterization  of
the wastes  by  the analysis  of the  processes  and  the  materials used appear to give
inaccurate descriptions of the resulting wastes.  The data indicate that each waste is
unique and individual reactivities may be best assessed by identifying respective chemical
constituents. This information supports the pure chemical  approach used in determining
the reactivities of the wastes in the development  of the  compatibility method.

      For  convenience in referencing  when using the compatibility  method, the pure
chemicals known  or expected to be present in  hazardous wastes are classified  under
41 different Reactivity Group Numbers (RGN)  based on molecular functional  groups or
chemical reactivities.
ORGANIZATION OF THE REPORT

      The report is organized into three main sections (Section 4 to 6) and supplemented
by five  appendices (Appendices  1 to  5).

-------
      Section 4 is the method for determining the compatibility of binary combinations
of most hazardous  wastes.  The section includes the application and  limitation of the
method, the compatibility reaction criteria and  Reaction Codes (RC), the step-by-step
procedures, compatibility analysis flow chart,  and typical examples of how to determine
compatibilities based on  available  information.

      Section 5 contains the  description and  use of the hazardous wastes  compatibility
chart.  The chart is used to predict  the potential adverse reaction  consequences when
two  types  of  wastes are mixed or allowed to come in contact  with one another.  In
the same section are the explanations of the multiple RC used to designate the adverse
reaction  consequences and  the limitations  of  the use of the chart.

      The last part of the handbook consists of  the five appendices.  Appendix 1  lists
the chemical substances  known or expected  to  be present in hazardous wastestreams.
The  list  was compiled  from a literature search  and surveys of  hazardous  wastes
practices.  The list is  used to obtain RGN  of  waste constituents when the composition
of wastes are known specifically.

      Appendix  2 lists hazardous  wastes by  molecular functional groupings or classes
and  by  chemical reactivities.  The  list was compiled  from  the  same sources  as  used
in Appendix 1.  The appendix is used to obtain the RGN  of wastes when the composition
is known  nonspecifically  by chemical classes or  reactivities  only.

      Appendix 3 compiles an industry index against Standard  Industrial  Classification
(SIC) code number and lists wastestreams by  common or generic  names.   The two  lists
are used to obtain the RGN of wastes when the  compositions are known nonspecifically
by common or generic names only.

      Appendix 4 outlines the potential adverse  reaction consequences predicted in the
Hazardous Wastes Compatibility Chart (Figure 6).   The appendix identifies the binary
combinations of wastes by RGN and  describes the corresponding potential  incompatible
reaction consequences.   The reaction consequences were  compiled from the same
references as used in Appendix  1  and  from basic chemical reactions.

      Appendix  5  consists  of some  documented  case histories of accidents caused by
the mixing of incompatible hazardous wastes.   The information  from these cases  was
used as  basic  reference in the development of the  Hazardous Wastes  Compatibility
Chart and the list of binary  wastes  reactions in Appendix 4.


SCOPE,  APPLICATIONS  AND LIMITATIONS  OF THE REPORT

      The report provides  a systematic method for determining the compatibility of
most binary  combinations  of  hazardous wastes  produced  by industry and agriculture.
Additionally, the report  provides a list of compounds known or expected  to be present
in hazardous wastes.  Lastly,  the report classifies the compounds as  well  as the  wastes
irlto chemical reactivity groupings and lists the potential adverse  reaction  consequences
of most  incompatible  binary  combinations  of  the groupings.

      This report will be a useful reference in  the management of hazardous wastes.
It will be  useful to the  waste generators in identifying and segregating their  wastes
for disposal; to the transporters for segregating, combining, and/or proper containerizing

-------
of the wastes; to the site operators for determining co-burial  of  containerized  wastes
in the same cell or co-ponding of bulk wastes; to the regulatory agencies for determining
suitability of  sites for disposal of certain  wastes;  and to those who  perform chemical
treatment of  the wastes for purposes of detoxification or resource recovery to  prevent
possible  uncontrolled  reactions.

       This report cannot be used  to predict  all the  potential incompatible reactions
of  any two given wastes,  and neither can  it  furnish  information  on  all  hazardous
wastestreams because of the  tremendous variety of waste types,  constituents,  and
characteristics.   Additionally,  the  report  does  not  address ternary combinations of
incompatible  hazardous wastes.

                                     SECTION 2

                                   CONCLUSIONS
       An extensive review of the literature and surveys of hazardous waste management
practices has shown that adverse reactions  can result from  the mixing or combination
of incompatible hazardous wastes.  These reactions have been  categorized into twelve
classes on the basis of reaction products with the  potential of causing public  health
and  environmental damage.   The  twelve classes  are:   1) heat generation,  2) fire,  3)
gas  formation,  4) formation  of toxic fumes,  5) generation of flammable  gases,  6)
volatilization of  toxic or flammable substances, 7) formation of  substances  of greater
toxicity,  8)  production of shock and friction-sensitive compounds,  9)  pressurization  in
closed vessels, 10) solubilization of toxic substances,  11) dispersal of toxic dusts,  mists,
and  particles, and 12)  violent polymerization.

       Three primary causes  of the combination of incompatible wastes were  identified,
namely:

       1)     Insufficiency or inaccuracy of information about  the  wastes,

       2)     Indiscriminate  handling of the wastes, and

       3)     Indiscriminate  waste  disposal practices.

       In  order  to  prevent  and/or minimize the chances of  combining incompatible
hazardous wastes and to avoid  the resulting adverse reactions, it  was concluded that
a method of determining waste compatibility is necessary.  Such a method was developed
for the binary combinations  of waste types.  A compatibility method addressing ternary
or more combinations was considered but found to be unwieldy.  In the  binary method
the  potential for occurrence of any one of the twelve identified reactions  was  taken
as an indication of incompatibility.   The determination of the  occurrence of incompatible
reactions was based on the assumption that the waste  reactions  are results of pure
chemical  components of the wastes  reacting  at ambient  temperature and pressure.
These assumptions  are  made primarily for reasons of  simplification; however,  it  is
believed  that they are justified  in  view of  most  disposal and transport  situations.

       The development of  the  step-by-step procedures  for  the  compatibility method
required the  assignment of waste components into reactivity groups based on molecular
functionality and reactivity  characteristics.   Using this procedure, it was found that
the  reactivity group(s)  of  the  components  of one  waste paired  with  the  reactivity
groups of another waste could predict the potential occurrence  of certain incompatible
reactions.  A two-dimensional graphic display  was determined  as the  best method for
presenting the reactivity groups and allowing intergroup pairing.   This resulted in the
development  of   the  compatibility  chart  presented  in  Figure 6  of Section  5.   Color

coding  of  group  pairings  can be  added  to aid in rapid  determination of  potential
incompatibilities.

       A primary conclusion that was reached from this work was that there  is a dearth
of information about the reactivities of  chemicals in the  complex matricies of wastes.
Many factors assuredly  do  greatly influence waste component reactions.  Among these
are  temperature,  catalytic effects of  dissolved  or participate metals, soil reactions,
and  reactions with  surfaces of  transport vehicles  or  containers.   The  simplified
compatibility methodology that has been developed in this study, however,  should provide
a  useful aid  to persons involved in generating,  transporting, processing, and  disposing
of hazardous wastes if  reasonable  precaution is taken in its use.

                                RECOMMENDATIONS
       The incompatible  reactions predicted for the  different binary combinations of
hazardous wastes in the hazardous wastes compatibility chart are based on a literature
search and  consideration  of  basic chemical reactions only.   The reactions should be
validated using actual  wastestreams where possible.  The  reactions designated by the
reaction code  "U"  on the  chart, which  means potential  adverse reaction consequence
may occur but little information is available in  the literature, should be investigated.
The multiple reaction codes on the chart should also be further investigated to determine
the validity of the  given  order  of occurrences of  the incompatible  reactions, and the
possible  occurrences of additional reaction consequences.

       Additional investigation is recommended  to determine the possibility of con-
solidating the present 41 reactivity groupings of  the wastes to a smaller number based
on  general  reactivity  characteristics  alone, instead  of  on both molecular  functional
groups and  reactivities.

       It  is  also  recommended  that  a  field test apparatus for  determining  waste
reactivities be investigated. This apparatus can be extremely  useful in the management
of hazardous  wastes.

     METHOD FOR DETERMINING COMPATIBILITY OF  HAZARDOUS WASTES

APPLICATION

      This method is  used to determine  the  compatibility reactions  of  most binary
combinations of most hazardous wastes.  The method is applicable  to  four categories
of wastes based on information available, namely: 1) compositions  unknown, 2) com-
positions known specifically, 3) compositions known nonspecifically by chemical classes
or reactivities, and 4) compositions known nonspecifically by common or generic names
only.

      The method starts with a compatibility analysis flow chart (Figure 1) indicating
the analysis pathways  for the  four  categories  of  wastes  above, followed by  the
compatibility reaction  criteria and the stepwise  precedures for  determining  compati-
bility.

COMPATIBILITY REACTION CRITERIA

      The reactions between binary combinations of wastes are NOT COMPATIBLE
according to this  method when the following undesirable  and hazardous consequences
are produced:

      The  RC are usecj in the compatibility chart (Figure  6) to denote the potential
hazardous reaction consequences that can result from the binary combinations  of the
wastes.
PROCEDURES FOR DETERMINING COMPATIBILITY

      Five main steps are required in the step-by-step procedures for determining the
reaction compatibility of  any Wastes A and B.   The procedures are conducted with
reference to Figure 1 (Flow Diagram for Determining Hazardous Wastes Compatibility),
Figure 6 (Hazardous Wastes Compatibility Chart), Appendix  1  (List of Chemical Com-
pounds), Appendix  2 (List  of Wastes Constituents by Chemical Classes and Reactivities,
and Appendix  3 (List of Wastestreams  by Common or Generic Names).

Step  It  Obtain as much information as  possible  about  the history  and compositions
of the  wastes.   Such information can  usually be  obtained from the records of the
waste producers,  the  manifests  that  accompany the wastes  and examination of the
processes  that produced  the  wastes.  When no information is available, collect rep-
resentative samples of the wastes and submit  them for analysis.  The analysis should
provide information  on the specific chemical constituents or  classes of  compounds in
the wastes.

Step  2;  Starting with Waste  A,  list down on the worksheet (Figure 2) on the column
for Waste A, the chemical names or classes of  compounds in the  waste or the generic
names of the waste.  The composition  of the  waste is  Known Specifically  when the
constituents are listed by chemical names such as ethylene glycol, sodium nitrate,  etc.;
Known  Nonspecifically by classes when the constituents are identified only by chemical
classes  or reactivities such as alcohols, caustics, mercaptans, etc.   The waste  is Known
Nonspecifically  by generic names when classified as spent  caustic, tanning sludge,
copper  plating waste,  etc.

Step  3;  When the composition of  Waste A is  Known Specifically by chemical names,
consult Appendix  1.   Find the chemicals in the list and note down their respective
Reactivity Group  Numbers (RGN) in the Worksheet.  If  a  chemical component is not
listed in Appendix 1, look for its synonym(s)  (Ref. 7, 14,  21, 30,  32, 37, 41, 54, 59,
69, 70,  76) and note down its  RGN (Section 4.4,  Example 1, Note 2).  When no synonym
can be found,  the RGN of the component may be alternatively  determined  based on
its chemical  class or reactivity (Section  4.4, Example 1, Note 3).

       When the composition of the waste is Known Nonspecifically by chemical classes
or reactivities only,  consult Appendix 2  and note down the corresponding RGN on the
Worksheet (Section 4.4, Example  2).

       When the composition  of  the waste is Known  Nonspecifically but classified by
common or generic names, consult Appendix 3 and note down  the RGN in the Worksheet
(Section 4.4,  Example 3).

Step  4;   Repeat  steps 2  and 3 for Waste B  and list down  the information on the
column for Waste B on the Worksheet.

Step 5; Consult the Hazardous Wastes Compatibility Chart in  Section 5 and determine
the Reaction Codes (RC) between any binary combinations of RGN of Wastes  A against

-------
B.  Note all RC on the Worksheet.  If no RC are listed, Wastes A and  B are compatible
and vice versa.
SPECIFIC EXAMPLES

       The following  examples illustrate  the  stepwise  procedures  for  determining  the
compatibility of hazardous wastes:

       Example 1 - Composition  Known Specifically

Step 1;  The manifests identify the constituents of  the wastes specifically as follows:

       Waste A contains ethylene glycol, chhlorobenzene,  and hydrochloric acid.

       Waste B contains isooctane  and sodium sulfide.

       List the components of  Waste A on  the  column for Waste  A on the Worksheet
(Figure 2). Consult Figure 1 and  follow the  compatibility flow diagram  for Composition
Known Specifically.

Step 2; Find the RGN of the components ethylene glycol, chlorobenzene and hydrochloric
acid in Appendix  1.   Thus,  the RGN for  the  components are:   ethylene glycol  - 4,
chlorobenzene - 17, and hydrochloric  acid - 1.

Step 3;   Record the  RGN of the components on the Worksheet.

Step 4; List the components of Waste B on the column for Waste  B on the Worksheet.
Repeat steps 2 and 3 for Waste  B.  thus, the RGN  of  the components of Waste B  are
as follows:  Isooctane-29,  and sodium sulfide-33.

Step 5;   Pair up each listed RGN  of Waste A against that  of Waste B.   Hence  the
following  pairs are possible: 4 & 29, 4 <5c  33,  17 & 29,  17  & 33, 1 <3c  29,  1 and 33.
For  each  pair, find the Reaction Codes (RC) in the Hazardous Wastes Compatibility
Chart  (Figure  6).  Record the corresponding RC for each pair in the Worksheet.  Note
that the RC for all binary combinations of  RGN for wastes A and B are blank  except
for RGN  1 &  3 which  are    GF.  The completed Worksheet  is  shown in  Figure 3.

Conclusion;  Waste A is incompatible with Waste B.  Potential hazard of  toxic  (GT)
and flammable (GF) gas formations are indicated if the wastes are mixed.

NOTE  1;   If Waste A  contains  a water  reactive constituent (RGN 107) and Waste B
contains an aqueous component,  then  water (RGN 106)  should be  listed  as one  of  the
hazardous components for  Waste B  in Step 1.

NOTE  2;  If a chemical  constituent is not listed in  Appendix  1, its synonym(s) can  be
obtained from chemical references (Ref.  7, 14,  21,  30, 32, 37, 41, 54, 59, 69, 70, 76)
and used  to determine its RGN.  For example,  Pyranton is  a  chemical not listed in
Appendix  1.  By consulting the Merck Index (Ref. 54), the synonym for this chemical
is diacetone alcohol which is  listed in Appendix 1 with RGN of 4 and 19.   Thus,  the
compatibility of this compound with other waste constituents can be established in the
same way as Example 1.

                                        10

-------
NOTE 3;  When a synonym  for an unlisted  compound  cannot  be found, the RGN under
which it is listed may be derived  by  molecular functional groups or chemical reactivity.
For example, isobutyl carbinol is  not listed  in Appendix  1.  The Merck Index (Ref. 54),
however,  lists  the compound as an alcohol.   Therefore, by  consulting Appendix  2,
isobutyl carbinol may be  classified under RGN  4.   When  the compound  contains more
than one  functional groups, all applicable RGN must be identified.   A  compound like
peroxosulfuric acid is not listed  in Appendix 1.   This  compound, however, is known  to
be a strong mineral acid as well as a very powerful oxidizing  agent.  Therefore, the
compound may be  classified under RGN  2.

      Example 2  - Composition  Known Nonspecifically  by Chemical  Classes or Reac-
                   tivities.

Step 1;  The manifests identify  the  wastes constituents as follows:

      Waste A contains toxic metals,  aldehydes and  alcohols.

      Waste B contains toxic metals and oxidizing agents.

      List the components  of Waste A on  the  column for Waste  A  on the Worksheet
(Figure 2).  Consult Figure 1 and follow the compatibility flow diagram for composition
Known Nonspecifically  by Chemical  Classes or  Reactivities.

Step 2;  Find the  RGN for  toxic metals, aldehydes  and  alcohols in Appendix 2.   Thus,
the RGN for the  components  are:  toxic metals -  24, aldehydes -5,  and alcohols -  4.

Step 3;  Record the  RGN of the components on the Worksheet.

Step 4;   List the components of Waste  B  in the  column for Waste  B on the Worksheet.
Repeat  steps 2 and 3  for Waste B.   Thus, the RGN for the components  of  Waste B
are: toxic metals  - 24  and  oxidizing agents -  104.

Step 5:   Determine  the  compatibility of  Waste A and B in the same  manner as  in
Step 5 of Example 1.  The completed Worksheet for this example is shown in  Figure
4.

Conclusion;   Waste A  is incompatible with Waste B.   Potential for  heat  and fire
generations  (Hp)  are indicated if the wastes are mixed.

      Example 3  - Composition  Known Nonspecifically  by Common or Generic  Names
                   of Wastes

Step 1;  The manifests describe  the wastes as  follows:

      Waste A is a metal  plating waste.

      Waste B is  a pectin  waste from the production of citrus products.

      List the generic name of Waste  A  on the column  for Waste A  on  the Worksheet
(Figure 2).  Consult Figure 1 and follow the compatibility flow diagram for  composition
Known Nonspecifically  by Common  or  Generic  Names of Waste.


                                         11

-------
Step 2;  Find the RGN  of "metal  plating waste" according to Appendix 3.  The RGN
for  this generic waste are 11 and 24.

Step 3;   Enter  the  RGN of  Waste A on the Worksheet.

Step »;   Enter the waste generic name of "Citrus  Pectin Waste" on the column for
Waste B on the Worksheet.  Repeat steps 2 and 3 above for Waste B.  Thus, the most
likely RGN for this generic waste are  1 and 4.

Step 5;  Determine the compatibility  of  Waste A  and  B in the same manner  as in
Step 5 of Example  1.   The  completed Worksheet for this example is shown in Figure
5.

Conclusion;   Waste A is incompatible with Waste B.  Potential  hazards of toxic and
flammable  gas formations   ( GTGF)   are indicated if the wastes  are  mixed.   Also
solubilization (S) of metals  may occur.

                   HAZARDOUS WASTES COMPATIBILITY CHART
INTRODUCTION

       The chart (Figure  6)  is the single  most important part of this  report.  It is a
quick and ready reference for determining the compatibility  reactions of most binary
combinations of hazardous  wastes.   It is used in conjunction with the detailed  com-
patibililty analysis  procedures  in Section 4.

DESCRIPTION  OF  THE CHART

       The 41  reactivity  group classifications of hazardous wastes  listed in Appendix
2 are  presented in this chart.

       The first colulmn  of  the  chart  lists the  reactivity groups by Reactivity Group
Numbers (RGN).  The first  34 RGN which are based on chemical classes or molecular
functional groups are listed  consecutively from  1 to 34.  The  last 7  RGN which are
based  on general chemical reactivities  are listed consecutively from  101 to 107.   The
second column  lists  the  corresponding reactivity group  names.   The  first  34  group
names are each followed by a number of reaction  squares equal to their  respective
RGN.  In other  words, RGN 1  is followed by 1 square, RGN 2 by 2 squares, etc.   The
group  names designated  by RGN 101  to  107 are followed by  34, 36,  37, 38, 39, 40
and  41 squares, respectively.  The  squares form rows as well as columns of squares
on the chart.   A  terminal  square  of  a row represents a  binary combination of one
reactive group with itself and is labelled with  its  RGN.  The  terminal squares  serve
as headings for the columns of  squares  and as a whole  appear as a diagonal row of
squares on the chart.  An additional bottom  row of-squares is correspondingly labelled
as the diagonal row of squares.  The RGN on the first column of the chart and  those
on the diagonal and  bottom  rows  of  squares provide the reference  coordinates for
locating the  potential hazardous reaction consequences of any  binary combinations of
the wastes reactivity  groups.

       The rest of the squares  on the chart are either  blank or  filled in with Reaction
Codes  (RC).  When a square  is blank,, the wastes in the binary combination  represented
by that square  are  compatible. Conversely,  any  RC on the squares indicate potential
incompatible reactions that  can  result from  the combination  of the wastes reactivity
groups represented by the  individual  squares.   The predicted reactions are based on
the combinations of  the  most reactive chemicals in the respective reactivity groups.
All the binary wastes combinations designated with RC are described in greater detail
in  Appendix  4.   Where  waste combinations  are believed to be incompatible but no
sufficient supporting data have been found in  the literature, incompatible reactions are
also  noted and marked on  the chart  with RC or "U".  The  RC are identified in the

                                         IS

-------
legend on the upper right hand  corner of the chart and described in detail in  Section
4.2.   The multiple  RC  are  explained in Section 5.4.

PROCEDURES FOR USING THE CHART

Step 1;  For the  binary combination of any reactivity groups, first find the Reactivity
Group Number (RGN) of  the  first  group on the first  column of the chart.

Step 2;  Find  the  RGN  of  the  second  group from  the  bottom  squares  of RGN.

Step 3;  Find the intersecting reaction square  for the two  RGN.

Step 4;  Note the  Reaction Code(s) (RC)  in the square.

Step  5;  Refer to  the  legend on the chart or  Section 5.4 for the explanation of the
RC.

Step  6;  When no  RC  is found on the reaction square, the two groups of wastes are
compatible.  When  any  RC  are noted on the square, the wastes are incompatible when
mixed or allowed to  come  in contact with one another.

EXPLANATION OF THE  MULTIPLE  REACTION CODES

       For many  binary combinations, multiple Reation Codes (RC) are used to  denote
the reaction consequences.  The order in which these letter codes appear in the squares
corresponds  to the order in which the consequences can  occur.  For example, in RC
(HFE), the first letter denotes the initial or primary hazardous consequence of a binary
reaction which in this case is HEAT  generation.  The second and  third letters  denote
the resulting secondary consequences of the production of FIRE and  EXPLOSION from
the heat generated by the primary  reaction.  In  some cases the third  letter code refers
to  a  resulting tertiary  consequence such as the evolution of a toxic gas from a fire
caused by excessive HEAT generation ( HFGT).   Where the codes GTGp appear,  the
GASES evolved are  TOXIC and FLAMMABLE such as hydrogen sulfide,  hyarogen cyanide,
or carbon disulfide.  The relative positions of the letter codes to one another  in this
case  bear no significance.  The codes can  also be written as  GF^y.

LIMITATIONS OF THE  CHART

       The  potential reaction consequences predicted  by the chart are based on  pure
chemical reactions  only  at  ambient  temperature  and  pressure.    Concentration,
synergistic, and antagonistic effects have been assumed not to influence the reactions.
The reactions have  not as yet been  validated on  actual  wastes containing the chemicals.

                                   APPENDICES
APPENDIX I.  LIST OF  CHEMICAL SUBSTANCES

       This appendix  lists  the chemical  substances that may be found  in  hazardous
wastestreams.   The list is  not  inclusive  but  represents the data compiled  through  a
literature survey and examination of hazardous waste management practices.

       The list  consists of three  columns.  The first column lists the chemical or trade
names in alphabetical order.   The trade names  are denoted by asterisks  (*).  The
second column list the synonyms or common  names of the chemical substances when
available.  The third  column lists the reactivity group numbers (RGN) assigned to the
substances as  derived in Appendix  2.  A compound may  be assigned  more than one
RGN.

       This appendix  is  used to obtain the RGN of  waste  constituents when known
specifically.  The RGN is used to determine the compatibility of the combinations  of
wastes according to the  compatibility method  in Section 4.

       The chemical substances  listed were compiled  from several sources.   The list
of Hazardous Wastes and Hazardous Materials and  List of Extremely Hazardous  Wastes
and  Extremely Hazardous Materials in California's Industrial  Waste Law of  1972 (Ref.
44) served as the starting reference.  The primary sources of information consisted of
published reports (Ref. 1, 7, 12,  13, 14, 32, and 52) identifying the hazardous chemical
substances in industrial  wastestreams.   Additional  chemical  entries were  abstracted
from  the  California  Waste  Haulers  Record  files (Ref.  10),  California   Extremely
Hazardous Waste  Disposal  Permit files  (Ref.  8), and the  TRW Systems'  report  on
recommended methods of reduction, neutralization, recovery,  and  disposal of  hazardous
wastes (Ref.  77).

groups according to  molecular functional  groups,  chemical classes, or chemical  re-
activities.  The substances are divided  into 41 Reactivity Group Numbers (RGN)  and
listed consecutively in the first two pages of  this appendix.  RGN 1 to 34 are categorized
based on  molecular  functional groups,  101  to  107  on  chemical  reactivities.    The
reactivity groupings  here  are  identical to  those depicted in the  Hazardous Wastes
Compatibility Chart (Figure  6) in Section  5 of this report.

      The succeeding pages of this appendix  contain the  tabulations of the  chemical
substances in  Appendix  1  under their respective RGN.  All trade names in the tables
are denoted by asterisks  (*) consistent with the notations used  in  Appendix 1.

      This appendix  is  used to obtain the  RGN  of hazardous wastes  when the waste
constituents  are  known  only  by chemical  classes,  molecular  functional  groups,  or
chemical reactivities.   The information  is used to determine the  compatibility  of  the
combinations of the wastes according  to the compatibility method in Section  4 of  this
report.

      The listing  was developed  from the  same  primary  references used  in  Appendix
1, namely  Ref.  1,  7, 8, 10,  12,  13, 14, 32, 44, 52, and 77.  The reactivity groupings
of waste constituents presented here are not inclusive.  Additions or deletions may be
made in  the  future  when more information  is  available  from  the  management of
hazardous wastes.

APPENDIX 3.  INDUSTRY  INDEX  AND  LIST  OF  GENERIC  NAMES OF  WASTE-
               STREAMS

      This appendix consists of two separate but related tables.  Table 1 is the Industry
Index which lists names of industries alphabetically with their  corresponding Standard
Industrial  Classification (SIC) code numbers.   Table 2 is the list of Generic Names of
Wastestreams.

      This appendix  is  used  to  determine  the RGN  of  wastestreams  when  their
compositions  are  not known specifically but are identified by their generic or  common
names.   The SIC code number of one  wastestream produced  by a given industry  is
obtained from the Industry Index table (Table 1).  This  number  is located in  the  List
of Generic Names of Wastestreams (Table 2).   Then the  corresponding industry source,
generic  name of the  waste,  and its  RGN are noted from the  table.   The process  is
repeated for  the  second waste.  The  RGN for the two types of  wastes  are entered in
the  compatibility worksheet (Figure 2) and  the  compatibility  method in Section 4.

      The primary references used in the compilation of the following tables are the
same ones used in Appendix 1, namely Ref.  1,  7, 8, 10, 12, 13, 14,  32, 44, 52, and
77.  The  lists are in  no way complete nor  are the  assignments of RGN to particular
wastestreams absolute.  Changes in manufacturing processes  and practices may change
the waste compositions thus  resulting in different generic types of wastes.

             amyl cation.  Aliphatic azo and diazo compounds, particularly diazo-
             alkanes, can polymerize violently with heat generation. Organo azides
             can also decompose exothermically with strong acid to form nitrogen
             gas and the respective cations.  An  exotherm also results from  the
             acid-base reaction of hydrazines with  mineral  acids as hydrazines  are

             The aqueous fraction of strong mineral acids will  react with nitrides
             evolving caustic and flammable ammonia  gas.  The acid-base reaction
             of mineral acids and nitrides can also evolve much  heat and ammonia.

1 + 26       MINERAL ACIDS + NITRILES

             Exothermic hydrolysis of nitriies to the corresponding carboxylic acid
             and ammonium ion is  known to occur with mineral acids.  Extremely

             catalyzed hydration forming  the corresponding aldehyde or ketone,
             with possible addition of  the  hydrogen halide in the case of halogen
             acids.

             Strong mineral acids  can  act  as  initiators in the  polymerization of
             these  compounds.    The  reactions  are  exothermic  and  can  occur
             violently.
             Ref. 51.

1  + 104      MINERAL ACIDS + STRONG  OXIDIZING  AGENTS

             Many combinations of strong mineral acids and strong oxidizing agents
             are sensitive to heat and shock and may decompose violently.   The

             mineral acids.   The heat  generated  can cause spontaneous ignition.
             Some reducing agents such  as metal phosphides and inorganic sulfides
             evolve extremely toxic and flammable  fumes of phosphine and hy-
             drogen sulfides,  respectively.

             acids.

1 + 107      MINERAL ACIDS + WATER REACTIVES

             Group 107 compounds not only share the characteristic that hazardous
             consequences can result from their contact with water;  they are also
             generally extremely reactive with most of  the other compounds listed.
             In  many cases  much  heat is  generated along  with  toxic  and/or
             flammable gases.  Explosions may occur,  or highly unstable mixtures
             may result.   For  this reason,  it is recommended that  Group  107
             compounds be completely isolated from the other  compounds.   Many
             of  these Group 107 compounds are also pyrophoric, especially those
             which are also classed as strong reducing agents.

             to  oxidation  and can  evolve  toxic  fumes of  nitrogen  oxides upon
             exhaustive  oxidation.   Hydrazines are especially susceptible to  oxi-
             dation and  inflame upon  contact with oxidizing agents.  Many of the
             compounds  in  this group such as diazomethane and  the azides are
             very unstable and can  decompose explosively upon heating.

2 + 13       OXIDIZING MINERAL ACIDS  +  ESTERS

             Exhaustive  oxidation of esters  can cause decomposition with  heat and
             possible ignition of the  more  flammable esters.  Conversion  to the

             The action of acid on these metals  produces  hydrogen gas and heat.
             Due to the large surface area of these forms  of metals,  the  reaction

             proceeds much  slower  than in the  case of powders, a  definite fire
             hazard exists.   Of the metals listed in Group 23, only  zirconium is
             not attacked by nitric  acid.
             Ref. 54.

2 + 24       OXIDIZING  MINERAL ACIDS + TOXIC METALS

             Many of the  compounds  in Group 24 are  very easily solubilized  by
             strong acids, consequently, the toxic metal compounds are converted
             into forms which are more easily transported  and  assimilated.  Some
             of these compounds have other hazardous properties and are classified
             elsewhere.
             Ref. 54, 69.

2 + 25       OXIDIZING  MINERAL ACIDS + NITRIDES

             Nitrides are extremely strong bases and will participate in  an acid-base
             reaction evolving much heat.  This reaction  can proceed with explosive
             violence  due to the  instability of metal nitrides  and the generation
             of flammable ammonia gas.
             Ref. 7,  69.

2 + 26       OXIDIZING  MINERAL ACIDS + NITRILES

             The  primary hazard  in mixing these types of compounds appears  to
             be oxidation of  the nitriles with  generation of heat and  toxic fumes
             of nitrogen  oxides.   In some  cases  such as acetone cyanohydrin and
             propionitrile, extremely toxic hydrogen cyanide gas is known to result
             from  mixing with  strong acids.   These fumes  are also flammable.
             Mixtures of nitric acid and acetonitrile  are high explosives.

2 + 27       OXIDIZING  MINERAL ACIDS + NITRO COMPOUNDS

             These acids  can  decompose nitro compounds to produce heat and toxic
             fumes of  nitrogen  oxide.  This oxidation  can be  extremely  violent.
             Mixtures  of  nitric  acid  and nitroaromatics  are  known to  exhibit
             explosive  properties.   Mixtures of some nitroalkanes  (nitromethane)
             with nitric acid can  also be  detonated.

2 + 30       OXIDIZING MINERAL  ACIDS  +  ORGANIC PEROXIDES

             The lower molecular  weight organic peroxides and hydroperoxides are
             very sensitive to heat  and shock.  Mixing of oxidizing mineral acids
             with such unstable compounds can cause heat generation  due  to the
             oxidizing capacity  of the acids and acid catalyzed hydrolysis.  These
             reactions can  cause explosive  decomposition.

2 + 31       OXIDIZING MINERAL  ACIDS  +  PHENOLS AND CRESOLS

2 + 32       OXIDIZING MINERAL  ACIDS  +  ORGANOPHOSPHATES

             Excess  oxidizing acid can decompose these  compounds to yield  heat

             oxides.

2 + 33       OXIDIZING MINERAL  ACIDS  +  SULFIDES

             Toxic and flammable hydrogen sulfide  gas can be generated by the
             action  of these acids on inorganic sulfides.   These sulfides  can also
             be oxidized exothermically to  sulfur  dioxide, also a  toxic gas.   This
             reaction can  occur very violently.
             Ref. 69.

2 + 34       OXIDIZING MINERAL  ACIDS +  EPOXIDES

             Epoxides are very easily cleaved  by acids with heat  generation.  This
             ring  opening  can  be the initiating  step in the formation of epoxy
             resins,  and uncontrolled  polymerization can  result in extreme  heat
             generation. The  oxidation capacity of these acids can cause ignition
             of  the  epoxides.

              Oxidizing  mineral  acids can decompose substances in Group 101  with
              heat generation and  possibly  fire.   Toxic gases may also be formed
              as combustion  products,  but  the  type of gas will depend  upon  the
              composition of these miscellaneous  substances.

2 + 102       OXIDIZING  MINERAL ACIDS + EXPLOSIVES

              Such  strong  acids  can easily detonate compounds in  this  group  of
              explosives  due to  the  heat generated upon  mixing.   The  oxidizing
              character  of these acids merely enhances the possibility of detonation.

2 + 103       OXIDIZING  MINERAL ACIDS + POLMERIZABLE  COMPOUNDS

              As  in  note  1 +  102, these acids can  act as  initiators in  the poly-
              merization of many compounds.  These reactions  are exothermic and
              can occur  violently.  In addition, these acids can oxidize the compounds
              of Group  103,  producing  more heat and possible  toxic fumes.

2 + 105       OXIDIZING  MINERAL ACIDS + STRONG REDUCING AGENTS

              Mixing of compounds in these two  groups can  result in very violent,

              water.
              Ref. 69.

 3 +  4       ORGANIC ACIDS + ALCOHOLS and GLYCOLS

              The organic  acids  of primary concern  in this  combination  are those
              with  a-substituted halogens such as  chloroacetic acid, and a- and
              B-substituted carboxyl groups such  as  oxalic acid and malonic acid.
              These  acids are comparable in strength to strong mineral  acids and
              can  catalyze  dehydration and esterification in alcohols and glycols
              with  heat  generation.  Polyhydric  alcohols  and  polybasic  acids can
              polymerize by  esterification  with much heat evolved.   Due to their
              acid strength,  these halo organic  acids would  be more  accurately
              compared  to acids  of Group 1 in  terms  of reactivity.  Hereafter,
              refer to Group I  to find the reactivity of these acids.   The  non-
              substituted  monobasic  aliphatic and  aromatic acids  are  relatively
              nonreactive with alcohols and glycols  and  esterify only with strong
              mineral acids or  other catalysts present.

             Exothermic condensation reactions can occur between these two types
             of compounds.   The acidic character of the organic acids may be
             sufficient  to catalyze the  reaction.   Polybasic and unsaturated acids

5 + 30       ALDEHYDES + ORGANIC  PEROXIDES

             A  mixture of' aldehydes and hydroperoxides results in formation of
             ot-hydroxy peroxides which are unstable  to heat and  stock.  Acyl
             peroxides such as diacetyl peroxide can decompose with slight heating
             resulting in formation of CO, and methyl  radicals.   These  radicals
             can abstract hydrogen from  aldehydes and  initiate a  chain reaction
             and produce much heat.  Alkyl and acyl  peroxides can  decompose in
             the same manner and initiate free radical reactions involving aldehydes
             to yield heat.  Peroxy acids  are very strong oxidizers in  themselves
             and can  react violently with aldehydes.

5 + 10*      ALDEHYDES + OXIDIZING AGENTS

             Aldehydes  are very easily oxidized by these compounds resulting in
             formation of the corresponding carboxylic acid or complete decom-
             position.   In both cases,  heat  is  evolved,  and fires can  result.

             Upon exhaustive  oxidation with peroxy acids, amines can  yield heat
             and toxic  fumes  of nitrogen  oxides.   Treatment of   amines with

              Alkyl  metal halides can  undergo  a  Grignard reaction with primary
              and secondary  amines forming the  corresponding alkanes.   Enough
              heat may  be evolved to  cause a fire  hazard.  See Note 7  +  21  for
              the combination of amines and alkali and alkaline earth metals.  Other
              reducing  agents may also react  with  amines  in a similar  manner
              yielding heat and hydrogen gas.

 8+9        AZO COMPOUNDS + CARBAMATES

              Diazo alkanes could add to the carbonyl group of  the carbamate with
              liberation  of N2«   Aryl  diazonium  compounds  can react with  the
              nitrogen of  the carbamate group, also  yielding nitrogen.  Azo com-
              pounds appear to be relatively inert towards reaction with carbamates
              while  hydrazines may form  hydrazones with the carbonyl with heat
              generated.   Information  regarding these reactions, however, is very
              scarce.

              Aryl dianonium salts  can react with metallic cyanides to form  the
              corresponding nitrile,  an  inorganic salt,  and  gaseous nitrogen.  Diazo
              alkanes, however,  are much  less subject  to  addition  of  a base like
              cyanide.   Azo  alkanes,  azo aromatic compounds, and  hydrazine  and
              its derivatives  do not appear  to react with metallic cyanides.

             Aliphatic  diazo  compounds, especially  diazomethane, are extremely
             reactive  as alkylating  agents  and may react  with  esters  in  some
             manner  to yield  heat.  The reaction, however, is not substantiated
             in the literature reviewed.  Aromatic  diazo  and  azo compounds do
             not appear  to undergo potentially hazardous reactions  with ester.

8 + 17       AZO COMPOUNDS + HALOGENATED ORGANICS

             Aliphatic diazo compounds  can  act as nucleophiles in substituting for
             the halogen in aliphatic  halogenated organics.  Nitrogen gas is  evolved
             from  such a  reaction.    Although  hydrazines  are  relatively  weak
             nucleophiles, they can react with primary and  some secondary halides
             with some heat  generated.

8 + 18       AZO COMPOUNDS + ISOCYANATES   J

             Isocyanates are susceptible to nucleophilic attack  at the carbon and
             can consequently react  with diazo alkanes in this manner.   Gaseous
             nitrogen can result.  Hydrazines may also attack the  carbon but with
             less vigor.
             Ref. 71.

8 + 19       AZO COMPOUNDS + KETONES

             Although ketones are not as reactive as aldehydes with diazo alkanes,
             alkylation can occur with  water as a  catalyst releasing nitrogen gas.
             Electrophilic   substitution  of  quinones  can  occur  with  aromatic
             dizonium  cations yielding  nitrogen gas.  Although  hydrazines  form
             hydrazines with  ketones, the reaction  requires heating.

8 + 20       AZO COMPOUNDS + MERCAPTANS

             Aromatic  diazonium salts  can  form thioethers  with  mercaptans re-

             undergo the same reaction.
             Ref. 71,  79.

8 + 21       AZO COMPOUNDS + ALKALI  and ALKALINE EARTH METALS

             Molecules which react with these metals are characterized by having
             centers of  high elctron  density which can induce a localized  positive
             charge in  the metal.   The subsequent electron  transfer  is highly
             exothermic.   The compounds in Group 8 all have  centers  of high
             electron  density  in the  nitrogen and in the a-carbon in the  case of
             diazo  alkanes.   The  reaction  of these compounds  with the active
             metals of Group 21  can thus be very  exothermic and may  produce

8 + 22       A2O COMPOUNDS + METAL POWDERS

             Due to  the high surface area of these forms of metals and the high
             flamrnability of  hydrazine  and some of its  organic  derivatives, a
             combination  of  these  substances  in air  can  result  in  spontaneous
             ignition. Toxic nitrogen oxide  fumes can be formed.   Diazo alkanes
             polmerize very readily in the  presence of copper and  other  metal
             powders releasing much heat.

8 + 30       AZO COMPOUNDS + ORGANIC PEROXIDES

             Hydrazones are explosively oxidized  by  organic peroxides and hydro-
             peroxides yielding toxic nitrogen oxide fumes.  Diazo compounds may
             form more unstable peroxides with  hydroperoxides.  Organic peroxides
             and azo compounds are both  relatively sensitive to homolytic fission
             by heat or light.  Any situation where either factor is applied to this
             mixture might  result  in extremely fast and exothermic  free radical
             reactions.

 8  + 34       AZO COMPOUNDS  + EXPOXIDES

              Since epoxides are very susceptible to ring cleavage and polymerization
              by acidic or basic reagents, such reactions are possible with diazonium
              compounds and hydrazines.  In the case of the  diazonium  compounds,
              attack  of  the aryl  cation could occur on  the  oxygen with evolution
              of  nitrogen gas and  heat.  Hydrazines can act as bases in attacking
              one of  the ring carbons releasing heat.   Being  strong nudeophiles,
              diazo alkanes may also  cleave the ring at a carbon  with  generation
              of  heat and  nitrogen gas.

              The diazonium  ion  can act  as  a Lewis  acid  in catalyzing  various
              cationic polymerizations.  Diazo  alkanes are very strong nudeophiles
              and may add  to double bond systems to initiate polymerization.  All
              of  the  monomers listed in Group 103  may  be susceptible to poly-
              merization in  combination with  diazo alkanes.  Hydrazines may be
              basic enough  to catalyze anionic  polymerization in combination with
              diazo alkanes.  Hydrazines may be basic  enough  to  catalyze  anionic

              The  anion  formed  can further  decompose  upon reaction with more
              hydroperoxides to yield oxygen gas.  This decomposition  can  proceed

              Many   of  these  materials  are susceptible to oxidation  by  organic
              peroxides and can evolve toxic gases.  Heat and fire can  also result.
              Ref. 69.

30 +  102      ORGANIC  PEROXIDES + EXPLOSIVES

              If these  explosives  are not  detonated  upon  contact  with  organic
              peroxides,  the mixture can  be extremely  unstable and  sensitive to
              any shock or  slight heating.

30 +  103      ORGANIC  PEROXIDES + POLYMERIZABLE COMPOUNDS

              Olefinic bonds are particularly susceptible to attack  by  free  radicals
              generated  from organic peroxides and  hydroperoxides.   The poly-
              merization of vinyl, acrylic, and olefinic monomers listed in Group
              103 can  be initiated by these radicals with heat generated.

30 +  104      ORGANIC  PEROXIDES + OXIDIZING AGENTS

              Strong oxidizing  agents  can cause violent decomposition of organic
              peroxides and hydroperoxides yielding  heat   and  oxygen or  carbon
              dioxide.  The decomposition can be catalyzed by the metallic character
              as well as  the oxidizing properties of  these compounds.

APPENDIX  5.   CASE  HISTORIES  OF  ACCIDENTS  CAUSED BY  MIXING  INCOM-
                PATIBLE WASTES


       The format of the whole handbook was developed around the information obtained
from  the following  documented  case histories of  accidents  that  resulted  from the
mixing of incompatible hazardous wastes.   The list is  not  extensive, but the following
case histories definitely indicate that insufficient  or inaccurate information about the
wastes and  indiscriminate handling  and  disposal of the wastes are the primary causes
of accidents resulting from  the  mixing  of incompatible  hazardous wastes.

       The case histories are not  arranged  in any particular  order.  The adverse reaction
consequences from  the mixing  of the wastes are given as the titles followed by the
references  where  they  were  reported.   For  more detailed discussions of  the  case
histories,  the user is referred to these  references.

       The  information from these  case  histories are particularly useful  as starting
blocks in the  development  of the  Hazardous Wastes  Compatibility Chart  (Figure  6),
and the List of Incompatible  Binary Combinations of Hazardous Wastes and the Potential
Adverse  Reaction Consequences  (Appendix ft).

 1.    Violent Reaction, Pressure Generation in Tank  Truck (Ref. 8)

       In Richmond, California,  a hazardous waste hauler mixed, in his  30-barrel  tank
       truck, a  liquid waste  containing  butyl acetate in  xylene with an etching waste
       containing sulfuric acid, nitric acid  and hydrofluoric  acid.  A  hydrolysis reaction
       took  place.   The reaction generated pressure in  the tank and blew the safety
       relief valve while the  truck was travelling through a residential area.   A private
       residence was sprayed with  the  hazardous mixture.   No one  was injured, but
       considerable clean-up  and repainting  of  the house was required.

 2.    Heat  Generation  and  Explosion from Reuse  of Contaminated  Drums  (Ref. 12)

       An employee  transferred  two  5-gallon cans  of waste  vinyl  cyanide and water
       from  a still to a  supposedly  empty  waste  drum.    As  the  employee  rolled the
       drum  to  a storage  area  across the road, it expoded.   Waste material sprayed
       out on the  employee.  He believed that he saw a flash  at the time  of the
       explosion. The drum was thrown  approximately  ft8 feet, wrapping around a  steel
       guard post.  The employee received thermal and possible chemical burns to both
       feet.

       The  waste drum contained  still  bottoms  from  the  stripping of a vinylation
       mixture.   The exothermic reaction, causing the drum  to rupture, was probably
       a combination of cyanoethylation and polymerization.

-------
3.    Formation of Toxic Gas in  Sanitary  Landfill (Ref.  8)

     In Los Angeles County,  a tank truck emptied several thousand gallons of cyanide
     waste onto refuse at a sanitary landfill.   Another  truck subseqently  deposited
     several thousand gallons of acid waste  at the same location.  Reaction between
     the acid and the cyanide evolved large amounts of toxic hydrogen  cyanide gas.
     A potential disaster was averted when a local chlorine dealer was quickly called
     to oxidize the cyanide  with  chlorine solution.

4.    Formation of Toxic Gas in  Excavated  Site (Ref. 58)

     A load of acidic aluminum sulfate  waste was  inadvertently  discharged into an
     excavation already containing some sulfide waste. Hydrogen sulfide was released,
     and  the  lorry driver died  in  his cab  at the  landfill site.

5.    Formation of Toxic Gas and Explosion in Waste Tank (Ref. 38)

     Sulfide waste was added to soluble oil waste in  a tanker and subsequently added
     to other oily wastes in  a  tank.   Later treatment of the  oil with acid to break
     the emulsified oil resulted in evolution  of hydrogen sulfide.  Two operators were
     briefly affected  by the gas.   There was  also an explosion  in the tank.

6.    Formation of Toxic Gas at a Landfill  (Ref.
      At a sanitary landfill near  Dundalk,  Maryland, a  2,000-gallon liquid industrial
      waste load containing iron sulfide,  sodium sulfide, sodium carbonate and sodium
      thiosulf ate— along with smaller quantities of organic compounds— was discharged
      into a depression atop an earth-covered area of the fill.  When it  reached 8 to
      10 feet  below the  point  of  discharge, the  liquid started  to bubble  and fumed
      blue  smoke.   The smoke cloud quickly engulfed the truck  driver and  disabled
      him.   Several nearby workers  rushed  to his aid and were also  felled.   During
      the  clean-up  operation, one  of the county firefighteres  also collapsed.   All  six
      of the injured were hospitalized and treated for hydrogen sulfide poisoning.   It
      was not  determined whether  the generation  of  hydrogen sulfide  was  due to the
      instability of the waste  or the incompatibility  of  the  waste with some of the
      landfill materials.   The pH of  the  waste was measured  to be 13 before it left
      the  plant.

7.    Formation of Toxic Gas  in a Disposal  Well  (Ref.  8)

      At a land disposal site in southern California, a tanker  was observed unloading
      a  waste  listed as "waste acid (5%  HC1)"  into  a subsurface,  bottomless tank
      through an open  stack above  the ground.  Shortly after  the  unloading operation
      commenced, yellowish- brown  clouds of  nitrogen  dioxide  began  to emanate from
      the open  stack.  The  reactions appeared  to  have subsided  when  the  discharging
      of the wastes ceased.  However, an hour later, more NO-  started to spew from
      the stack.  The emission was halted by filling the stack with soil.  There were
      no injuries, but the incident created a  significant air pollution problem such that
      complaints from  nearby businesses  were received and a  factory  was evacuated.

-------
 *•    Fire.  Dispersal of Toxic Dusts from  Leaky Containers (Ref. 8)

      At a dump in Contra Costa County, California, a large number of drums containing
      solvents were deposited in a landfill.  In the immediate area were leaky containers
      of concentrated  mineral acids and several bags containing beryllium  wastes  in
      dust form.   The operators  failed to cover the waste at the end  of  the  day.
      The acids reacted with  the solvents  during the night, ignited them,  and started
      a large chemical fire.   There was possible dispersion of beryllium dust into the
      environment.  Inhalation, ingestion, or contact with beryllium  dust by  personnel
      could have  led to serious health consequences.

 9.    Volatilization of  Toxic Chemicals Due to Heat  Generation from Ruptured, Buried
      Containers  (Ref. 87        ~

      A load of empty pesticide containers was  delivered to  a disposal site in Fresno
      County,  California.  Unknown to the  site operator, several  full drums  of an
      acetone-methanol mixture was included in the load.  When the load was compacted
      by a  bulldozer,  the  barreled waste  ignited, engulfing  the bulldozer in flames.
      The  operator escaped unharmed, but the machine  was seriously damaged.   The
      ensuing fire, which also involved dispersion of pesticide wastes, was extinguished
      by firemen.  The firemen were examined to ensure that they were not exposed
      to pesticide dusts.

10.    Violent Eruption in  Waste Drum  (Ref. 58)

      At  an engineering work, hot  chromic acid waste was  inadvertently  added to' a
      drum containing methylene  chloride  waste from degreasing operations.   There
      was a violent eruption resulting in chemicals being sprayed locally in the workshop.
      Fortunately, no one  was harmed.

11.    Fire from  Sodium Waste Disposal (Ref.  12)

      A fire occurred in a laboratory when a few pieces of  scrap sodium, which had
      been placed in alcohol to effect decomposition, flashed  when discarded in a sink.
      Evidently the sodium had not been completely  decomposed and reacted with the
      water in the  sink.

12.    Formation of Shock  and Friction Sensitive  Substances  (Ref. 12)

      When a laboratory drain at a Los Angeles hospital was being cleaned by scraping,
      the  drain  pipe  exploded scattering  fragments of  metal from the  pipe.  Two
      subsequent attempts  to remove the residual piping with screwdriver and  hacksaw
      resulted  in explosions  in both instances.   Fortunately, no  one was injured in
      these explosions.  The cause  was later attributed  to shock-sensitive lead azide
      formed in the lead  pipes.   Apparently, used test  solutions, containing sodium
      azide as a  preservative, was routinely poured into the sewer  drain line.   The
      chemical  accumulated  in the pipes  and reacted with the lead in  the pipe to
      form  shock-sensitive, explosive deposits of lead  azide.

-------
13.    Formation of  Water  Soluble  Toxic Substances from  Ruptured  Drums (Ref. 8)

      In Riverside  County, California, several  drums of phosphorus oxychloride, phos-
      phorus thiochloride and thionyl chloride were inproperly dropped off at a dump.
      Later, during a flood, the drums were unearthed,  ruptured, and  washed down-
      stream,  releasing  hydrogen chloride gas.

14.    Fire at  a Disposal Site  (Ref.  8)

      A disposal site in central  California accepted a  load  of  solid  dichrornate salts
      and  was dumped in a pit along with pesticide formulations and empty pesticide
      containers.   For several days thereafter,  small fires erupted in  the pit because
      of the oxidation of the pesticide formulations  by  the dichromate.  Fortunately,
      the  site personnel were  able  to extinguish  these fires before  they burned  out
      of control.   No injuries  or property and equipment damage resulted from  the
      fires.

15.    Nitrogen Oxide Generation at a Sanitary Landfill (Ref. 8)

      A vacuum truck  driver picked  up a load of "nitric acid" from  an automotive
      specialities manufacturing company in early July 1976 and delivered it to a site
      in southern California for well disposal.  The well  was able to accept  only about
      50  gallons of  the waste.   The  driver then  took  the  remainder of the load  to
      another  landfill in southern California for  trench disposal.   Upon unloading, a
      reaction  took  place that  generated brown  nitrogen  dioxide fumes  that  were
      carried by the wind  and  interfered  with  traffic 500 yards away.

      Towards the end  of  the  month  the same driver  picked up another load of  the
      same type from the same company and delivered it directly to the second landfill
      site.  Upon arrival at the weigh  station, he was instructed to tell  the  caterpillar
      driver to "dig a deep hole."  The caterpillar operator dug a hole approximately
      12 ft deep,  12 ft  wide, and 20 ft long into a previously filled area.  The truck
      driver said that he observed damp ground and decomposing refuse in the trench.
      The  driver then unloaded his  truck and  backed away  from the trench because
      he did  not  want  to  be exposed to the  hazard he  had observed on  a previous
      occasion.  Sure enough he  observed a dense brown cloud emanating from  the
      trench and could not return to his truck  until- its  contents had been drained and
      the hazard reduced.

      A chemical analysis of a retained sample from the load showed that it contained
      approximately  70%  nitric acid  and 5%  hydrofluoric acid along with  aluminum
      and  chrominum.   The  sample was  fuming  when  it was  taken  from  the  truck.

16.    Violent Reaction  of  A1C1,  Wastes from  Smelting  Processes  (Ref.  8)

      Five steel barrels  were picked up from a  reclaimed aluminum and zinc smelting
      company and delivered to a Class I disposal site  in southern California.  While
      rolling the drums off the  truck, one  of  the barrels  ruptured and its contents
      reacted  violently  with the liquid in the  pond at  the working face of the  fill.
      The  other four barrels were buried separately.   No injuries resulted from  the
      accident.

-------
      One of  the vice presidents of the company confirmed that the reactive material
      in the  waste was 95% A1C1.  condensate collected in  the  steel  barrels.   This
      condensate results from passing Cl. gas through the molten aluminum metal  to
      remove magnesium.

17.    Explosion of Waste TDI Containing Drums (Ref. 8)

      A company using toluene diisocyanate (TDI)  in the manufacture of plastic and
      foam rubber automobile products collected and stored on-site  its TDI  wastes  in
      55-gallon metal drums with  clamp-type lids.   After an extended period of  time,
      thirty such  drums had been  accumulated.  A  hauler was contacted to transport
      the wastes to a Class I site  in Southern California.  The hauler stored the drums
      in  an open  area at  his facility for  approximately 2  weeks.  Heavy  rainfall
      occurred  during  this  period.  Upon delivery  of the drums to  a disposal site, a
      violent  explosion ruptured  one of the drums.   Apparently, during storage  some
      water condensed or leaked into  the drums through the clamp-type lids.  Trans-
      portation of  the  drums then provided the agitation and accelerated the reaction
      between water and TDI.  The rapid production of CO2 caused extreme pressure
      build-up in  one of the drums  and subsequent  violent rupture.

      There were no injuries associated with this incident.

18.    Dirt  Contaminated  with NaCKX Causes Fire (Ref. 8)

      In  1972 at  a disposal site in Southern California, reaction of sodium  chlorate
      with  refuse  started a fire that lasted for  2  hours.   There were no  injuries
      associated with the incident.

      Dirt  contaminated with NaClCL was drummed and transported as "NaCl" to the
      sanitary landfill.    The drums  were emptied on  refuse.  The contents of the
      drums were  wet but  reacted with the refuse to cause a fire.

      A similar incident  involving NaClO.  and refuse producing a fire occurred  in
      1973.   This  incident  involved  containerized  material that reacted with refuse
      when a container ruptured during the  covering operation.

19.    Cyanide Generation at a Sanitary Landfill (Ref. 8)

      A standard procedure at a  Southern California disposal site for handling liquid
      wastes  containing cyanides and spent caustic  solutions was to  inject these  loads
      into covered wells dug into  a  completed section of  a sanitary  landfill.  Routine
      air sampling in the vicinity  of the wells detected low levels of HCN.  Sampling
      in the well  head detected more than  1000 ppm  HCN.  No cyanide was detected
      during  addition  of  the spent caustic to a new  well.   On the basis of  these
      discoveries, use of the wells was discontinued.   Cyanide gas apparently formed
      in the well as a  result of lowering  of  the pH  of the waste by  CO2, and organic
      acids that were  produced in the decomposition of refuse.

20.   Phosphorus Oxychloride and Water Caused Fatality (Ref. 12)

      A delayed  reaction  between  phosphorus oxychloride and water in a  55-gallon
      drum caused violent  rupture of the drum and killed a plant operator.  The steam
      and  hydrogen chloride gas generated  by the reaction caused an  explosion that
      propelled the bottom head of the drum approximately 100 yards from the scene.

21.   Nitric Acid  and Alcohol Cause  Explosion  of Tank Car (Ref. 12)

      During the process of transferring 64% nitric acid to a supposedly empty tank
      car, the tank car exploded. An investigation revealed that the tank car contained
      a small residual  of  alcohol  that  was converted to acetaldehyde by the acid.
      The heat  of reaction  vaporized the  acetaldehyde and subsequently ignited the
      acetaldehyde-air mixture causing an explosion.   No injuries or fatalities resulted.

22.   Nitric Acid  - Ammonia Fire Generate Toxic Fumes (Ref. 8)

      In a fertilizer  warehouse in Carroll  County,  Arkansas,  a mixture of  ammonia
      and  nitric acid  ignited and destroyed  the  plant.   Toxic fumes generated by the
      blaze  forced the evacuation of the town's residents.   No injuries or fatalities
      were reported.

23.   Vacuum Truck  Rupture Caused  by Formation of Hydrogen Gas  (Ref. 8)

      In Los Angeles a vacuum truck containing an unknown quantity of residual wastes
      picked-up  a spent sulfuric acid metal stripping  solution.  On  the way to  the
      disposal site a  violent  explosion occurred, rupturing the tank and injuring  the
      driver.  Subsequent  investigation  revealed that  the  residue  in  the tank before
      the  pick-up of  the  acid solution  contained aluminum and  magnesium  turnings
      and  fines.  The action  of the acid on these metal particles produced  hydrogen
      gas  and heat.   Extreme pressure build-up  resulted in the  violent rupture of  the
      tank.

24.   Toxic  Gas  Generation  From  Buried  Drums  of  Silicon  Tetrachloride  (Ref.  8)

      Drums of silicon tetrachloride were buried in a hazardous waste disposal site in
      northern California.   After about  a  year  and a  period  of intense rains, dense
      fumes of  toxic  and  corrosive  hydrogen chloride permeated  the soil cover and
      spread over the vicinity of the burial area.   The  metal drums had apparently
      rusted through and the water reacted  with SiCl^, forming  hydrogen chloride gas;
      No injuries were reported, and the gas evolution was controlled by covering the
      trench with  a layer  of  limestone  and soil.

 16. ABSTRACT
         This report describes a method for determining  the  compatibility of the binary
    combinations of hazardous wastes.  The method consists of two main parts, namely:
    1)  the step-by-step  compatibility analysis procedures, and 2) the hazardous wastes
    compatibility chart.   The key element in the use of  the  method is the compatibility
    chart.  Wastes to  be combined are first subjected through the compatibility proce-
    dures for identification  and classification, and the  chart is used to predict the
    compatibility of the wastes on mixing.

         The chart consists of 41  reactivity groups of hazardous  wastes designated by
    Reactivity Group Numbers  (R6N).  The RGN are displayed in binary combinations on
    the chart, and the compatibility of the combinations  are designated^by Reaction
    Codes (RC).

         The method is applicable to four categories of  wastes based on available
    compositional information:  1) compositions known specifically, 2) compositions
    known nonspecifically by  chemical classes or reactivities, 3) compositions known
    nonspecifically by common or generic names of wastes, 4) compositions unknown
    requiring chemical analysis.
