8.1 EXPLOSIVE HAZARD
8.1 EXPLOSIVE HAZARD
All storage batteries give off a highly explosive mixture of hydrogen and
oxygen when gassing. Therefore, never permit sparks, open flame, or lighted

cigarettes near a storage battery. Post "No Smoking" signs where they are clearly
visible to anyone entering the battery room area. A nonmetallic flashlight is
visible to anyone entering the battery room area. A nonmetallic flashlight is
desirable for battery inspection. Use only alcohol thermometers when
taking electrolyte temperatures. Keep all battery connections tight to avoid
sparking. Never lay any metallic object on top of a battery. A class C 10-
pound fire extinguisher should be mounted just inside the battery room
door. Carbon dioxide (CO

8.2 ELECTROLYTE HAZARD
8.2 ELECTROLYTE HAZARD
When handling electrolyte, wear face shields (face shields should not have
metal reinforcing rims, which could cause a battery short if dropped), rubber
aprons, and rubber gloves; avoid splashes. The electrolyte is injurious to
skin and clothing and must therefore always be handled carefully. The eyes
in particular should be guarded. If acid is splashed into the eyes or
anywhere on the skin, flood with water for at least 15 minutes and get
medical attention. Do not use bicarbonate of soda on the skin, which may
aggravate the burn. For neutralization of acid electrolyte spilled on the floor
or rack, a bicarbonate of soda solution--1 pound per gallon of water--is
recommended.

For neutralization of ni-cad battery electrolyte (potassium hydroxide), keep
a concentrated solution of 20 ounces of boric acid powder per gallon of
water available for neutralizing spills on skin or clothing. Use plain water to
wash up spills of potassium hydroxide on the cells or racks. Care must be
taken to prevent the solution from getting into the cells.

A combination eye-wash, face, and body spray unit must be located within
25 feet of each battery room or battery system. These units can be
permanently mounted and connected to the facility's potable water system
