INSPECTION, TEST AMD MAINTENANCE GUIDANCE
FOR FIRE SAFETY SYSTEMS
INTRODUCTION
Fire safety systems fi ling fire suppression, detection and alarm) are crucial to
defend against fire. However, they are rendered useless if no routine maintenance or
testing is provided to assure their operation when needed. This document provides limited
guidance for periodic inspection, testing, and maintenance of fire safety systems commonly
found at EPA laboratory facilities. The document is intended as a starting point to help
safety personnel focus on key aspects of fire safety systems maintenance. The user will
need to evaluate their facilities to determine other specific system maintenance
requirements.
The document is divided in two portions. The first portion describes fire safety
components and their functions. The second portion is a Checklist of inspection, testing
and maintenance requirements of specific components. The Checklist, can be used
independently to ensure that fire protection components are evaluated on a regular
scheduling basis, or it may be integrated into a facility preventive maintenance program.
It can be useful in developing a fire prevention plan for the facility. The following
systems and components are discussed: water supply, automatic sprinklers, standpipe and
hose, fire pumps, fixed and portable extinguishers, fire alarm, fire doors, dampers and
emergency lighting.
Records o£ all testing, maintenance and inspection activities should be kept on file for
periodic review. Atr.aehment A provides examples of how inspection activities can be
recorded.
Although facility personnel can visually inspect various system components, many of the
testing and maintenance and some of the inspection procedures require handling of the
equipment or component. Those procedures requiring handling should be performed by
qualified fire protection contractors. Any test or maintenance procedure having a direct
connection to a centra 1 or fire department should b<~. made only after proper notice
is given to the signal receiving station. Fire protection systems are required to be
acceptance tested upon their installation. This document does not address acceptance
testing of new systems.

EPA policy requires that facilities follow the National Fire Protection Association (NFPA)
standards. This document was developed using the latest NFPA standards. Requirements
that are imposed by other local author it'should also be observed. At. the end of each
fire^safety component discussion, the reader is directed to the applicable NFPA
publications which the user will need to perform complete inspections, Ft r rol lowed.
FXRE SAFETY SYSTEM COMPONENTS
Each fire safety system component performs one or more functions of detection, suppres-
sion, or life safety. The water supply system is vital to fire suppression. Water which
may come from tlis-: city water system or water storage tanks, supplies automatic sprinklers,
standpipe and hose systems, and fire hydrants. A properly designed and maintained fire
alarm system will help limit loss of property and life by providing ea?. ty warning. Life
safety features such as fire walls and enclosed stairways are normally designed into the
building construction. Several components of life safety systems need to be inspected and
maintained to ensure that people can escape a building safely. This portion of the
document describes key fire safety components and their operation.

WATER SUPPLY SYSTEMS
Water for fire protection is conveyed to a facility by various methods, including water
storage tanks, public water mains, dedicated fire mains and puhli. vettn hyd^-tnts. At EPA
facilities, lei if- commonly supplied through storage tanks and public fire raains. Fire
hydrants are norma 11y puhUcH owned and the local jurisdiction is responsible for their
upkeep. Fire hydrants axe used in emergencies to obtain water from the public water
supply. The most common type of hydrant is the dry barrel? it is used in locations
susceptible to freezing. Wet barrel hydrants are used where there is no danger of
freezing. Different portions of hydrants (e.g., piping, monitor nozzles, hose, hydrant
house) require routine inspection, test, and maintenance.
Water storage tanks hold a specified amount of water to augment water supply to the
facility or serve as the primary water source in remote areas. Tanks typically are
provided with control valves, check valves (which direct the flow of water), heaters fin
freezing climates), fire department connections, ladders, drain outlets, water level
alarms, and level indicators. Fire department connections, commonly referred to as
"Siamese connections," usually consist of a dual 2 1/2-inch outlet outside the building.
The fire department connections are interconnected to standpipes or automatic sprinkler
systems. The fire department attaches hose lines to these connections to boost the water
capacity, during a fire emergency,
Refer to NFPA 25, Standard for the Inspection, Testing and Maintenance of Water Based Fire
Prevention Systems, Chapter 6: Water Storage Tanks and Chapter 7: Private Fire Mains for
more detail.
AUTOMATIC SPRINKLER SYSTEMS
A sprinkler system is an integrated system of small discharge nozzles (sprinklers), an
automatic water supply, and underground and overhead piping, The system is usually
activated when the heat from a fire fuses a metal alloy in the sprinkler. The water
within the system then discharges over the fire area.
The vertical piping which connects the overhead piping and the underground water supply is
called the system riser. The riser is usually between 4 ^and 8 inches in diameter and
normally painted red. System components or function indicators which need to be inspected
- 3 -
DRAFT - JUNK 1994
-------
or tested {such as water control valves, alarms, pressure gauges! are normally located
close to or on the system riser. Figure 1 shows a layout of a typical sprinkler system.
Sprinkler systems and other systems directing water supply require valves at strategic
locations and intervals which control the flow \ They may be needed to shut off
systems after operations, or to isolate portions of the system for repair or
maintenance. Valves (including control valves, Outside Screw and Yoke (OS&Y) or Post
Indicator Valve {PIV)) have a system to indicate whether the valve is closed or open.
Check valves are installed to isolate separate sources of water supp iy; they direct the
flow of water toward the system. Alarm check valves generate an alarm when water flows
through the system. Gate valves are normally found on both sides of a check valve and are
used to isolate check valves for maintenance operations.
Other system connections and drains are provided to test water supply. Water flow test
connections are provided at specific locations te jm low flow tests of water suppl ies.
These test connections verify the operation of the water flow alarm devices such as water-
motor gong, pressure switch or flow switch. They also indicate the amount of time for
water to flow to the sprinkler. The fire department can pump water into the sprinkler
system through the fire department connection. These connections are used to supplement
the water supply. Drains are needed for maintenance operations such as flushing the
system.
The main types of sprinkler systems found at EPA facilities are discussed below. They are
wet pipe, dr> pipe, and pre-action. Each type of system has unique function indicators or
components which requite Ji t1event treatments and frequencies for inspection or testing.
For additional information on automatic sprinkler systems refer to NFPA. 'J5, Chapter 2:
Sprinkler Systems, NFPA 13, Installation of Sprinkler Systems,
Wmt Pipm Spxi nklmr Syattaag
Met pipe sprinkler systems have their piping filled with water and the sprinklers are
closed. When the sprinklers reach their operating temperature, they open and waf ex-
discharges immediately. Met pipe sprinkler systems are used only in heated buildings.
Some buildings may have small unheated areas, such as a cold room or walk-in freezer and
so an nantifreeze loop" or dry pendant sprinkler is selected. Figure 2 shows features of
a wet sprinkler control valve. Figure 3 shows more detail on the sprinkler riser.

Dry Pipe Sprinkler 83mtmas
Unheat, ed ^ bu i It 11ngs which are subject to freezing have dry pipe sprinkler systems instead
of wo' ijyjbterns. However, the enclosure which houses the valves for dry pipe systems
must be heated. Dry pipe systems have their piping filled with air or nitrogen under
pressure. When the heat from a fire causes the sprinkler to open, the air pressure is
released. This permits the water pressure to push open the dry pipe valve. Water then
flows into the piping system and out the opened sprinkler. Dry pipe systems are often
less reliable than wet pipe systems due to additional maintenance requirements. Iignr^s 4
and 5 show details of a dry pipe sprinkler and valve. Figure 6 is a schematic of a dry
pipe system.
Delugm System*
In this system, the sprinklers are open; the water is held back by a deluge valve on the
system riser. When the fire detection system in the protected area activates, it trips
the deluge valve. This causes water to flow through all the sprinklers. These systems
are used in small areas such as cooling towers where water damage is not a concern.
fre-acfelon Systmnm
Pre-action systems are similar to deluge systems, except that the sprinklers are closed.
If water damage is a concern, as in computer rooms, a pre-action system is employed.
When the fire detection system trips the deluge valve, water enters the sprinkler piping.
However, water only discharges through the sprinklers which opened.
It is imperative to keep all records of sprinkler system evaluations on fx1p< Records of
testing, if compared over a few years, will help determine if the system capacity has
diminished. Attachment A is an example of inspection activities that should be recorded.
STANDPIPR AND HOSE SYSTEMS
Standpipe systems are a network of risers, piping, hose connections, and valves that allow
the Eire department or trained personnel to manual iy extinguish a fire. Water suppJy to
the stan.1p.ipo system can be automatic through water mains or provided by the fire
department. See Figure 7 for a drawing of a fire department connection. Components such
as hoses, cabinets, and nozzles must be routinely inspected. Consult NF Care, Use
and Service rnstn] luti ;n of Fire Hose Including Coupling and Nozzles, NFPA 25, Chapter 3:

FIRE PUMPS
Fire pumps are provided to fire protection systems to boost the pressure of an existing
water supply. Fire pumps are designed to operate at various flows and pressures; rated
pressure (pump design), churn pressure (no flow), and overflow pressure (!50% of designed
flow). When the fire pumps are tested, performance at these flow rates is observed.
The pump may be housed in a cut-off room in the facility, or in a detached pump house.
The engine for operating the pump is typically a diesel engine or an electric motor.
Pumps can operate manually, as well as automatically if provided with pump controllers.
Pumps which provide primary protection for the facility normally start automatically.
A preventive maintenance program which complies with the manufacturer's recommendations
must be established and implemented. Maintain records on all work performed on the pump,
engine, controller, and auxiliary equipment. A routine review of test records can provide
clues to water supply or pump deficiencies. Refer to NFPA 20, Standard for the
Installation of Centrifugal Fire Pumps and NFPA 25, Chapter 5; Fire Pumps for additional
informati on.
FIXED EXTINGUISHING SYSTEMS
Many types of automatic extinguishing systems other than sprinklers are availabie for f :i re
suppre n. They are typically selected based on the hazard type that will be protected.
For protection of electronic equipment, EPA normaliy selects C02 extinguishing systems and
pre-action sprinkler systems. Foam water systems are selected to protect areas using
large amounts of flamm ids. •
Carbon Dloxid9 Extiagul ehirtgr fly stoma (C03)
COj systems have C02 agent under pressure in cylinders and tanks. The tanks are accessed
through hoses to nozzles in the protected area. The systems apply C02 gas to fill an
entire room (total flooding systems), or to a specific area (local application).
- 11 -
DRAFT - JUNK 1994
-------
Additional information on these system can be obtained from NFPA 12, Carbon Dioxide
Extinguishing Systems, Figure 9 shows a typical C02 extinguishing system.
Foam-Wmtmr Systems
Fire fighting foam is used to combat fires involving flamn>ab!e and combust 1 b1 e liquids.
Foam is a mixture of air, water and a concentrated foaming agent. Aqueous Film Forming
Foam (AFFF) is the most popular type of extinguisher used at £f"\ id •, ^tiss. When AFFF is
discharged, it forms a blanket over the surface of the liquid, which smothers the fire.
Refer to NFPA 16, Chapter 8: Deluge Foam-Water Sprinkler and Foam-Water Spray Systems and
NFPA 25, Chapter 8: Foam-Water Sprinkler Systems for more information.
PORTABLE WISE EXTINGUISHERS
Portable fire extinguishers are required in most EPA facilities. Portable extinguishers
are selected according to the hazard they protect. The multipurpose dry chemical and
carbon dioxide extinguishers are most common at EPA facilities. The multipurpose dry
chemical can normally protect against most types of fires including electrical, ordinary
combustibles and flammable materials. C0a extinguishers are effective on electrical and
flammable liquid fires. The label on the extinguisher cylinder indicates what types of
fires it can extinguish.
FIRE ALARM SYSTEMS
A building fire alarm system provides audible and/or visual alarm signals when alarm
initiating devices such as a manual pull station, sprinkler* control valve, water flow
switch, or smoke detector operates, The alarm i rig devices are connected to the
fire alarm control panel, which continuously monitors these devices. Refer to NFPA 10,
Portable Fire Extinguishers for more detail.
A common fire alarm arrangement is one where an alarm initiating device operates and a
general alarm sounds. All alarm indicating devices, such as bells, horns arid lights
operate. Additionally, alarms sound at the alarm control panel. The alarm control panel
can be used to dea^twafce alarms during testing and maintenance operations. The alarm
annunciator panel indicates the location or type of device which activated, EPA
facilities usually have their fire alarm systems monitored by a central station. The

central station, upon receiving ar, alarm will make atlfciipts to verify the alarm.
If 31 cannot verify a false alarm, the Fire Department responds to the mstail ation. Fire
alarm systems are connected to emergency power supplies, which must be inspected and
maintained, as well.
Smokm Bmtmctors
Fires produce detect ~ ~ lantities of smoke before any significant rise in heat. Smoke
detection devices respond when smoke particles enter the units. Duct smoke detectors
cause the air handJing systems of a buildings ventilation system to shut down, thereby
preventing the .recirculation of smoke within the building. Magnete ri catxficial smoke
can be used to test smoke detectors. It is recommended t smoke be applied
from a distance of at least 12 feet to avoid damage to the unit.
The following documents provide additional information: NFPA 10.1, Life Safety Code; NFPA
72 H, Guide for Testing-.
Jfaafe DmtBctora
A heat detector works when the fusible elements within, the unit melt or when air or metal
in the unit expands in response to a predetermined heat level. Heat detectors are
provided on the initiating device circuits. SPA facilities have fixed temperature, rate-
of-rise, or rate compensation heat detectors. Fixed temperature heat detectors must be
replaced if they are tested using heat. Other restorable detectors can be safely tested
with a hair-dryer, or shielded heat lamp. Rate-of-rise and rate compensation detectors
can reset themselves after testing, Any detectors which fail to operate during tests must
be properly replaced. Records for testing, inspection, and maintenance must be kept on
file.
Manna. 1 Stations, Bella, and Horna
Basically, manual stations are electrical switches housed in a red-colored box. They
operate upon breakii 11ing a lever, or using a key. Bells and horns generate
loud noises to indicate emergencies. Sometimes visual signals such as strobes and lights
are provided.

POMSR SUPPLY
Power supply to the alarm system can be provided by either commercial it and power
supply or an engine-driven, generator. Secondary power suj te alarm system must be
provided. It can cc >rage battery and charger, or an engine-driven generator.
Secondary power supplies normally support other systems as well, including fire pumps,
exhaust hoods and emergency lighting. Ml power supplies, including uninterrupted power
supplies {UPS!, have inspection, test and maintenance requirements. Jk routine maintenance
and operational testing program must be developed and implemented based on manuf .i-"t mer's
recommendat ions.
NFPA 110, Emergency and Standby Power Supply and NFPA 72, National Electrical Code discuss
power supply requirements in detail.
MISCELLANEOUS FIRE SAFETY COMPONENTS
Firm Doora
Fire doors are used to protect openings in fire-rated walls and partitions. They are
required to be sell -closing or automatic closing (i.e., close upon activation of detection
systems). It is imperative that fire doors are not kept open with wood jambs or door
chocks. Doing so compromises fire safety and the design flow rates of ventilation
systems. NFPA 80, Standard on Doors and Windows provides details on door t«sting.
Daunpora
Fire dampers are provided on some air distribution systems to limit the migration of heat
or flame across a fire barrier. They close automatically when they detect excessive heat
in the air distribution duct. Smoke dampers restrict the movement of smoke.
NFPA 90A, Installation of Air Conditioning and Ventilating Systems and NFPA 101, Life
Safety Code discuss fire and smoke dampers.
Emergency Lights
Emergency lighting is required at most EPA facilities. Laboratory work units require at
least 10 candles of illumination on the face of the hood during emergencies. Emergency
lighting must operate automatically in the event of any interruption of normal lighting.
- 18 -
DRAFT - JUNK 1994
-------
A secondary source of power is required. This can be storage batteries or emergency
generators.
Refer to NFPA 10.1, Chapters 5 and 31 for more information. Written records of testing
must be kept on file.
HOUHERKEPIIJ^ PRACTICES
Good housekeeping is a continuous eft ort by management and staff to control sources of
ignition and to facilitate emergency evacuation. Managers must ensure safe storage and
handling of" materials. A lack of facilities to store materials can result in blocked exit
waysi sprinklers, and fire extinguishers. In addition to adding to the fire load, the
accumulation of combustibles (outside the building as we11 as inside the building) may
hinder safe evacuation. The safe handling and storage practices for combustible and
f lammabJ liquids must be observed.
There is no required evaluation schedule per se. However, individuals performing
inspections should keep good housekeeping practices in mind. Further information can be
found in the Fire Protection Handbook, 17 th Edition, Section 2, Chapter 34.
