• Always wear eye protection, rubber gloves, and a protective vest when working near batteries. Remove
all metallic objects from hands and neck.
• Servicing and connection of batteries shall be performed by, or under the direct supervision of, personnel
knowledgeable of batteries and the required safety precautions.
• All gelled or liquid emissions from a valve-regulated lead-acid (VRLA) battery contain dilute sulfuric acid,
which is harmful to the skin and eyes. Emissions are electrolytic, which are electrically conductive and
corrosive.
• Batteries produce explosive gases. Keep all open ames and sparks away from batteries.
• Use tools with insulated handles, do not place tools on top of batteries.
• 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)
• 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 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 an accumulation of potentially
dangerous gas.
• 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,
re, 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.
• Under extreme overcharging conditions, lead-acid batteries can vent a mixture of hydrogen gas which is
explosive.
• All battery compartments must have adequate ventilation to prevent accumulation of potentially
dangerous gas. Ventilation should prevent trapped hydrogen gas pockets from exceeding a one percent
concentration as per regulation 70E of the National Fire Protection Agency (NFPA).
