Battery, lead/acid
Diesel fuel
Foam in tires
Gasoline
Hydraulic oil
Liquefied petroleum gas
Motor oil
The rest of this chapter lists manufacturers’
information you will need if you ever have to
control any of the above items during an upset or
emergency.
„
ANTIFREEZE (UN 1993)
Fire extinguishing media: Dry Chemical, foam,
or CO2.
Special fire fighting procedures: Water spray
may be ineffective on fire but can protect fire
fighters and cool closed containers. Use fog
nozzles if water is used. Do not enter confined
fire-space without full bunker gear. (Helmet with
face shield, bunker coats, gloves & rubber
boots). Use a NIOSH approved positive pressure
self-contained breathing apparatus. Keep
container tightly closed. Isolate from oxidizers,
heat & open flame.
Spill or leak: Small - mop up with absorbent
material & transfer to hood.
Waste disposal method: Small - evaporate until
all vapors are gone. Dispose of remainder by
legally applicable methods.
„
BATTERY , LEAD/ACID (UN 2794)
Extinguishing media: Dry chemical, foam, or
CO2.
Special fire fighting procedures: Use positive
pressure, self-contained breathing apparatus.
Unusual fire and explosion hazards: Hydrogen
and oxygen gases are produced in the cells
during normal battery operation (hydrogen is
flammable and oxygen supports combustion).
These gases enter the air through the vent caps.
To avoid the chance of a fire or explosion, keep
sparks and other sources of ignition away from
the battery.
Spill or leak: Remove combustible materials and
all sources of ignition. Contain spill by diking with
soda ash (sodium carbonate) or quicklime
(calcium oxide). Cover spill with either chemical.
Mix well. Make certain mixture is neutral then
collect residue and place in a drum or other
suitable container. Dispose of as hazardous
waste.
Wear acid resistant boots, face shield, chemical
splash goggles, and acid resistant gloves. DO
NOT RELEASE UNNEUTRALIZED ACID!
Waste disposal method - Sulfuric Acid:
Neutralize as above for a spill, collect residue,
and place in a drum or suitable container.
Dispose of as hazardous waste.
DO NOT FLUSH LEAD CONTAMINATED ACID
TO SEWER.
Waste disposal method - Batteries: Send to
lead smelter for reclamation following applicable
federal, state, and local regulations.
„
DIESEL FUEL (NA 1993)
Extinguishing media: Use water spray, dry
chemical, foam, or CO2.
Special fire fighting procedures: Use water to
keep fire-exposed containers cool. If leak or spill
has not ignited, use water spray to disperse the
vapors and to provide protection for personnel
attempting to stop a leak. Water spray may be
used to flush spills away from exposures.
Unusual fire and explosion hazards: Products
of combustion may contain carbon monoxide,
carbon dioxide, and other toxic materials. Do not
enter enclosed or confined space without proper
protective equipment including respiratory
protection.
Spill or leak: Contain spill immediately in
smallest area possible. Recover as much of the
product itself as possible by such methods as
vacuuming, followed by soaking up of residual
fluids by use of absorbent materials. Remove
contaminated items including contaminated soil
and place in proper containers for disposal.
Avoid washing, draining, or directing material to
storm or sanitary sewers.
Waste disposal method: Recycle as much of
the recoverable product as possible. Dispose of
nonrecyclable material as a RCRA hazardous
waste by such methods as incineration,
complying with federal, state, and local
regulations.
„
FOAM IN TIRES
Extinguishing media: Water, dry chemical,
foam, or CO2.
Special fire fighting procedures: Evacuate non
emergency personnel to a safe area.
