Special Fire Fighting
Procedures
Use positive pressure, self-contained breathing apparatus. Beware of acid splatter during water
application and wear acid-resistant clothing, gloves, face and eye protection. If batteries are on charge,
shut off power to the charging equipment, but note that strings of series connected batteries may still
pose risk of electric shock even when charging equipment is shut down.
Unusual Fire and
Explosion Hazard
Highly flammable hydrogen gas is generated during charging and operation of batteries. If ignited by
burning cigarette, naked flame or spark, may cause battery explosion with dispersion of casing fragments
and corrosive liquid electrolyte. Carefully follow manufacturer's instructions for installation and service.
Keep away all sources of gas ignition and do not allow metallic articles to simultaneously contact the
negative and positive terminals of a battery. Follow manufacturer's instructions for installation and
service.
6: ACCIDENTAL RELEASE MEASURES
Protective
Measures to be
Taken if Material is
Released or Spilled
Stop flow of material, contain/absorb small spills with dry sand, earth, and vermiculite. Do not use
combustible materials. If possible, carefully neutralize spilled acid with soda ash, sodium bicarbonate,
lime, etc. Wear acid-resistant clothing, boots, gloves, and face shield. Do not allow discharge of un-
neutralized acid to sewer. Acid must be managed in accordance with approved local, state, and federal
requirements. Consult state environmental agency and/or federal EPA.
Waste Disposal
Method
Dispose of as a hazardous waste. Dispose of in accordance with applicable local, state and federal
regulations.
7. HANDLING AND STORAGE
Handling & Storage
Store frost-free under roof; prevent short circuits. Do not store in sealed, unventilated areas. Seek
agreement with local water authorities in case of larger quantities. Avoid overheating and charging. Do not
use organic solvents or anything other than manufacturers recommended cleaners on the batteries. If
batteries have to be stored in storage rooms, it is imperative that the instructions for use are observed.
Charging:
There is a possible risk of electric shock from charging equipment and from strings of series connected
batteries, whether or not being charged. Shut-off power to chargers whenever not in use and before
detachment of any circuit connections. Batteries being charged may generate and release flammable
hydrogen gas. Charging space should be ventilated. Prohibit smoking and avoid creation of flames and
sparks nearby. Wear face and eye protection when near batteries being charged.
Other
Follow Manufacturers Recommendations regarding maximum recommended currents and operating
temperature range. Do not overcharge beyond the recommended upper charging voltage limit. Applying
pressure or deforming the battery may lead to disassembly followed by eye, skin and throat irritation.
