WARNING: SERIOUS INJURY CAN RESULT FROM CARELESSNESS WHILE HANDLING AND
WORKING WITH NICKEL-CADMIUM BATTERIES. PLEASE OBSERVE THE
FOLLOWING SAFETY RULES WHILE WORKING WITH THESE BATTERIES.
1. Remove all metal articles such as bracelets and rings.
2. Metal tools must be insulated.
3. Wear protective clothing and eye protection. The electrolyte can cause burns if in contact with skin or
eyes.
4. Do not smoke or hold naked flames near batteries on charge. These batteries give off a mixture of
oxygen and hydrogen during charge, which, if allowed to accumulate in a confined space, could cause
an explosion. Do not charge the battery on the bench with the cover on.
5. Do not mix lead-acid and nickel-cadmium battery servicing in the same shop area.
6. Do not use petroleum spirits, trichloroethylene or other solvents.
