Battery Safety Notes
Lead-acid batteries contain dangerous voltages, currents and corrosive material. Battery
installation, maintenance, service and replacement must be performed only by authorized
Any 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, 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.
• 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.) whenever installing, maintaining, servicing, or
• 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 2.2 kg (one pound) bicarbonate of soda to 3.8 liters (one gallon) of water. Report chemical spill
using your company’s spill reporting structure and seek medical attention if necessary.
• Never use uninsulated tools or other conductive materials when installing, maintaining, servicing or replacing
• 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
• A battery showing signs of cracking, leaking, or swelling should be replaced immediately by authorized
personnel using a battery of identical type and rating.
