WARNINGS

DANGEROUS CHEMICALS ARE USED IN

NICKEL-CADMIUM BATTERIES

The electrolyte used in nickel-cadmium batteries contains potassium hydroxide

(KOH), which is a caustic chemical agent. Serious and deep burns of body tissue

will result if the electrolyte comes in contact with the eyes or any part of the body.

Use rubber gloves, rubber apron, and protective goggles when handling the elec-

trolyte. If accidental contact with the electrolyte is made, use ONLY clean water

and immediately (seconds count) flush contaminated areas. Continue flushing

with large quantities of clean water. Seek medical attention without delay.

EXPLOSIVE GASES ARE GENERATED BY

NICKEL-CADMIUM BATTERIES

Hydrogen and oxygen gases are generated in explosive proportion while the nick-

el-cadmium battery is being charged. Charge the nickel-cadmium battery in a well-

ventilated area to reduce concentrations of explosive gases. Turn off the battery

charger before connecting or disconnecting the nickel-cadmium battery to prevent

arcing. Do not use matches or an open flame in the charging area. Arcs, flames, or

sparks in the charging area will ignite the gases and cause an explosion. The bat-

tery box cover must be removed and the battery case vent plug (if used) must be

open when charging.

DO NOT MIX SULPHURIC ACID AND KOH

The electrolyte used in nickel-cadmium batteries reach violently to the sulphuric

acid used in the more common lead-acid types of batteries. DO NOT add sulphuric

acid electrolyte to the battery; the mixing of the acid and KOH electrolytes will

cause a violent reaction which could result in the splattering of the mixture into

the eyes and onto the skin. Every effort must be made to keep nickel-cadmium bat-

teries as far away as possible from lead-acid batteries. Do not use the same tools

and materials such as screwdrivers, wrenches, syringes, hydrometers, and gloves

for both types of batteries. Any trace of acid or acid fumes will permanently dam-

age nickel-cadmium batteries on contact.
