tains sulfuric acid, which is poisonous and
highly caustic. Always follow these preven-
tive measures:
• Avoid bodily contact with electrolyte as it
can cause severe burns or permanent eye
injury.
• Wear protective eye gear when handling
or working near batteries.
Antidote (EXTERNAL):

lowed with milk of magnesia, beaten egg,
or vegetable oil. Get immediate medical
attention.
Batteries generate explosive, hydrogen
gas. Always follow these preventive mea-
sures:
• Charge batteries in a well-ventilated area.
• Keep batteries away from fire, sparks, or
open flames (for example, welding equip-
ment and lighted cigarettes).
