Battery Safety
When working with batteries, always work in a well-ventilated area. Batteries present a hazard, especially when
they have been in use for a long period of time. The following are some basic precautions for working around
batteries:
•
Always wear personal protective equipment (PPE).
•
Battery gases are extremely explosive. Smoking, sparks, or open flames could cause an explosion. When
opening a battery compartment, always allow ample time for battery gases to escape.
•
If the battery is corroded, clean it with a mixture of warm water and baking soda.
•
If battery acid gets on the skin or in the eyes, flush the area immediately with fresh water and seek medical
attention.
Check the battery’s condition only with proper test equipment.
Disconnect the Battery
When disconnecting the battery, always disconnect the negative (-) cable first, then disconnect the positive (+)
cable.
