Battery Safety Notes
Electrical Hazards
Battery systems represent a risk of electrical shock and high short circuit currents. The following precautions
must be observed when maintaining batteries:
•
Remove all personal metal objects (watches, rings, etc.)
•
Use insulated tools.
•
Wear eye protection and rubber gloves.
•
Observe circuit polarities.
•
Do not make or break live circuits.
•
Do not lay metal tools and hardware on top of the batteries.
The battery is enclosed in cabinets with limited access. Again, extreme caution must be exercised when maintaining
and collecting data on the battery system.
Disposal
•
Lead acid batteries are to be recycled. Batteries contain lead and dilute sulfuric acid. Dispose of in accordance
with Federal, State, and local regulations. Do not dispose of in a landfill, lake or other unauthorized location.
Chemical Hazards
•
Any gelled or liquid emissions from a battery is electrolyte, and contains dilute sulfuric acid which is harmful to
the skin and eyes; is electrically conductive; and is corrosive.
•
If electrolyte contacts the skin, wash immediately and thoroughly with water. If electrolyte enters the eyes, wash
thoroughly for 10 minutes with clean water or a special neutralizing eye wash solution and seek immediate medical
attention.
•
Neutralize any spilled electrolyte with the special solutions contained in a “spill kit” or with a solution of 1 lb.
bicarbonate of soda to 1 gallon of water.
Fire, Explosion, and Heat Hazards
•
Lead acid batteries can contain an explosive mixture of hydrogen gas which can vent under overcharging conditions.
•
Do not smoke or introduce sparks in the vicinity of the battery.
•
Do not charge batteries in a sealed container. The individual batteries must have 0.5 inches of space between
them to allow for convection cooling. If contained, assure the container or cabinet and room have adequate
ventilation to prevent an accumulation of potentially vented gas.
