7 NI-CD-CLEAR-CASE
Chemical Hazards
The electrolyte in Nickel Cadmium batteries, consisting of a dilute caustic potash solution with a lithium hy-
droxide component, is harmful to the skin and eyes.
To avoid injury:
The servicing and connection of batteries shall be performed by, or under the direct supervision of, personnel
knowledgeable of batteries and the required safety precautions.
Always wear eye protection, rubber gloves, and a protective vest when working near batteries. Remove all metallic
objects from hands and neck.
Batteries produce explosive gases. Keep all open flames and sparks away from batteries.
Use tools with insulated handles, do not rest any tools on top of batteries.
Wear protective clothing (insulated gloves, eye protection, etc.) when installing, maintaining, servicing, or replacing
batteries.
If any battery emission contacts the skin, wash immediately and thoroughly with water. Follow your company’s
approved chemical exposure procedures.
Neutralize any spilled battery emission with plenty of water. If necessary, use sand to soak up the spill before diluting
with water. Report a chemical spill using your company’s spill reporting structure and seek medical attention if
necessary.
Always replace batteries with those of an identical type and rating. Never install old or untested batteries.
Do not charge batteries in a sealed container. Each individual battery should have at least 0.5 inches of space
between it and all surrounding surfaces to allow for convection cooling.
All battery compartments must have adequate ventilation to prevent accumulation of potentially dangerous gas.
Ventilation should prevent trapped hydrogen gas pockets from exceeding a 1% concentration as per regulation 70E
of the National Fire Protection Agency (NFPA).
Prior to handling the batteries, touch a grounded metal object to dissipate any static charge that may have developed
on your body.
Never use uninsulated tools or other conductive materials when installing, maintaining, servicing, or replacing
batteries.
Use special caution when connecting or adjusting battery cabling. An improperly connected or unconnected battery
cable which makes contact with an unintended surface can result in arcing, fire, or possible explosion.
Immediately replace any battery showing signs of cracking, leaking, or swelling. Batteries should be replaced only by
authorized personnel with batteries of identical type and rating.

Battery Safety Notes
Recycling and Disposal Instructions
Spent or damaged batteries are considered environmentally unsafe. Always recycle used batteries or dispose of the
batteries in accordance with all federal, state and local regulations.
Equipment Cautions
Do not operate NiCd and lead-acid batteries in the same room. NiCd emissions will neutralize the lead-acid solution,
rendering the battery useless.
Overcharging the battery can result in a loss of capacity and excess release of gas.

WARNING!
Nickel cadmium
(NiCd) batteries contain dangerous voltages, currents and corrosive
material. Battery installation, maintenance, service and replacement must be performed
only by authorized personnel.
