WARNING

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

with large quantities of clean water for at least 15 minutes. Seek medical attention without delay.

EXPLOSIVE GASES ARE GENERATED BY NICKEL-CADMIUM BATTERIES

Hydrogen and oxygen gases are generated in explosive proportions 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 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 twill

cause a violent reaction which could result in the splattering of the mixture into the eyes and onto the skin.
