WARN I N G
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 batter-
ies. 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 contacts 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 bat-
tery corrosion or electrolyte makes contact with skin, eyes or cloth-
ing, take immediate action to stop the corrosive burning effects.
Failure to follow these procedures may result in death or serious
injury to personnel.
