Chemical Hazards
Any gelled or liquid leakage from a valve-regulated lead-acid (VRLA) battery contains dilute sulfuric acid,
which is harmful to the skin and eyes. Emissions are electrolytic, and are electrically conductive and
corrosive.
To avoid injury:
Servicing and connection of batteries shall be performed by, or under the direct supervision of, personnel •
knowledgeable of batteries and the required safety precautions.
Always wear eye protection, rubber gloves, and a protective vest when working near batteries. Remove all metallic
•
objects from hands and neck.
Batteries produce explosive gases. Keep all open flames and sparks away from batteries.
•
Use tools with insulated handles, do not rest any tools on top of batteries. •
Lead-acid batteries contain or emit chemicals known to the State of California to cause cancer and birth defects or •
other reproductive harm. Battery post terminals and related accessories contain lead and lead compounds. Wash
hands after handling (California Proposition 65).
Wear protective clothing (insulated gloves, eye protection, etc.) when installing, maintaining, servicing, or replacing
•
batteries.
If any battery emission contacts the skin, wash immediately and thoroughly with water. Follow your company’s
•
approved chemical exposure procedures.
Neutralize any spilled battery emission with the special solution contained in an approved spill kit or with a solution
•
of one pound bicarbonate of soda to one gallon of water. Report a chemical spill using your company’s spill reporting
structure and seek medical attention if necessary.
Always replace batteries with those of an identical type and rating. Never install old or untested batteries.
•
Do not charge batteries in a sealed container. Each individual battery should have at least 0.5 inches of space •
between it and all surrounding surfaces to allow for convection cooling.
All battery compartments must have adequate ventilation to prevent accumulation of potentially dangerous gas.
•
Ventilation should prevent trapped hydrogen gas pockets from exceeding a 1% concentration as per regulation 70E
of the National Fire Protection Agency (NFPA).
Prior to handling the batteries, touch a grounded metal object to dissipate any static charge that may have developed
•
on your body.
Never use uninsulated tools or other conductive materials when installing, maintaining, servicing, or replacing
•
batteries.
Use special caution when connecting or adjusting battery cabling. An improperly connected battery cable or an
•
unconnected battery cable can make contact with an unintended surface that can result in arcing, fire, or possible
explosion.
A battery showing signs of cracking, leaking, or swelling should be replaced immediately by authorized personnel
•
using a battery of identical type and rating.
Battery Safety Notes
Equipment Cautions
Do not operate NiCd and lead-acid batteries in the same room. NiCd emissions will neutralize the lead-acid solution, •
rendering the battery useless.
Overcharging the battery can result in a loss of capacity and excess release of gas.
•
Recycling and Disposal Instructions
Spent or damaged batteries are considered environmentally unsafe. Always recycle used batteries or dispose of the
batteries in accordance with all federal, state and local regulations.
WARNING!
Lead-acid batteries contain dangerous voltages, currents and corrosive material. Battery
installation, maintenance, service and replacement must be performed only by authorized
personnel.
