WARNING

To avoid injury, eye protection and acid-resistant gloves must

be worn when working around batteries. Do not smoke, use

open flame, make sparks or create other ignition sources

around batteries. If a battery is giving off gases, it can explode

and cause injury to personnel. Remove all jewelry such as

rings, ID tags, watches, and bracelets. If jewelry or a tool con-

tacts a battery terminal, a direct short will result in instant

heating, damage to equipment, and injury to personnel.

Sulfuric acid contained in batteries can cause serious burns. If

battery corrosion or electrolyte makes contact with skin, eyes

or clothing, take immediate action to stop the corrosive burn-

ing effects. Failure to follow these procedures may result in

death or serious injury to personnel.
