BATTERY SAFETY

 

CAUTION

Batteries normally produce explosive gases,
which can cause personal injury. Therefore, do
not allow flames, sparks or lit tobacco to come
near the battery. When charging or working
near a battery, always cover your face and
protect your eyes, and also provide ventilation.

Batteries contain sulfuric acid that burns skin,
eyes and clothing.

Disconnect the battery before removing or
replacing any electrical components.
