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

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

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

flushing tenth large quantities of clean water. Seek medical attention without delay

for eyes.

EXPLOSIVE GASES ARE GENERATED BY NICKEL CADMIUM BATTERIES

Hydrogen and oxygen gases are generated in explosive proportion while the

nickel-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 battery 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 reacts violently to the sulfuric

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

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

batteries 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

damage nickel-cadmium batteries on contact.
