Safety data sheet

5. Fire and Explosion Hazard Data
Extinguishing media : Small fire : Foam halogen and/or noninflammable gas fire extinguisher
Big fire : Large quantities of sprinkled and/or atomized water. (In this case to prevent
environmental damage, flush water has to treat appropriately.)
Particular hazards : Irritate，corrosive and/or toxicity gases may break out from the burning battery.
Proper fire fighting If possible, turn off their power first when batteries are on charge or remove ignition sourc and
remove batteries from the fire place.
Extinguish out the fire from where well air flow and windward.
Extinction water has to treat appropriately for preventing environmental damage.
Cool down enough the burnt batteries with plenty amount of water.
Try to put out fire in early stage. In this case to use protectors written below.
Protection for fire-fighter : Use positive pressure, self-contained breathing apparatus and wear acid-resistant face shield,
gloves and boots in fighting fire.
6. Accidental Release Measures
Spillage of Electrolyte (Sulfuric Acid)
Human body
Do not touch the spilled electrolyte, and walk around the spillage place.
Keep out outsiders from the spillage place.
Environment Spilled electrolyte has to treat appropriately for preventing environmental damage, such as
direct out flowing of the spilled electrolyte into the river, drain, etc..
Neutralization Neutralize spilled electrolyte with sodium bicarbonate, lime, etc. and flush with large quantities
of water. In this case to use protectors properly.
7. Handling and Storage
Handling Keep away from fire and sparks.
Handle with care and keep away from shock, upset, etc..
Do not short-circuit both battery terminals.
Charge Lead Acid starter battery in well ventilated areas.
Storage Store Lead Acid starter battery in cool and dry areas.
Batteries should also be stored under protection against rain, dew and sunlight.
Keep away from fire, dust source, harmful gas and immersion.
8. Exposure Controls / Personal Protection
