Have an approved fire extinguisher available and know how to use it. Inspect as required to ensure it is fully charged
and operable.
Remove rings, bracelets, wristwatches, and neck chains before working on any vehicle. Jewelry can catch on equipment
and cause injury, or may short across an electrical circuit and cause severe burns or electrical shock.
Lead-acid battery gases can explode. Do not smoke, have open flames, or make sparks around a battery, especially if
caps are off. If a battery is gassing, it can explode and cause injury to personnel.
Ventilate when charging or using in an enclosed space.
Wear safety goggles and acid-proof gloves when battery cover must be removed or when adding
electrolyte.
Avoid electrolyte contact with skin, eyes, or clothing. If battery electrolyte spills, take immediate
action to stop burning effects:
-
External: Immediately flush with cold running water to remove all acid.
-
Eyes: Flush with cold water for at least 15 minutes. Seek immediate medical
attention.
-
Internal: Drink large amounts of water or milk. Follow with milk of magnesia,
beaten egg, or vegetable oil. Seek immediate medical attention.
-
Clothing or Vehicle: Wash at once with cold water. Neutralize with baking soda or
household ammonia solution.
Wear safety glasses or goggles when checking batteries. Always check electrolyte level with engine stopped. Do not
smoke or use exposed flame when checking battery; explosive gases are present and severe injury to personnel can
result.
Disconnect battery negative cable at post prior to performing maintenance in immediate battery area or working on
electrical system. Such disconnections prevent electrical shock to personnel or equipment.
Battery acid (electrolyte) is extremely harmful. Always wear safety goggles and rubber gloves, and do not smoke when
performing maintenance on batteries. Injury will result if acid contacts skin or eyes. Wear rubber apron to prevent
clothing being damaged.
Remove all jewelry such as rings, dog tags, bracelets, etc. If jewelry contacts battery terminal, a direct short may result
in instant heating of tools, damage to equipment, and injury or death to personnel.
Check battery condition only with proper test equipment.
Batteries shall not be charged except in an open, well
ventilated area free of flame, smoking, sparks, and fire.
