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.
