SECTION VI - HEALTH HAZARD DATA
Under normal conditions of use, the battery is hermetically sealed.
Ingestion:
Swallowing a battery can be harmful.
Contents of an open battery can cause serious chemical burns of mouth, esophagus, and gastrointestinal tract.
Inhalation:
Contents of an open battery can cause respiratory irritation. Hypersensitivity to nickel can cause allergic
pulmonary asthma. Provide fresh air and seek medical attention.
Skin Contact:
Contents of an open battery can cause skin irritation and/or chemical burns. Nickel, nickel compounds, cobalt, and
cobalt compounds can cause skin sensitization and an allergic contact dermatitis. Remove contaminated clothing
and wash skin with soap and water. If a chemical burn occurs or if irritation persists, seek medical attention.
Eye Contact:
Contents of an open battery can cause severe irritation and chemical burns. Immediately flush eyes thoroughly
with water for at least 15 minutes, lifting upper and lower lids, until no evidence of the chemical remains. Seek
medical attention.
SECTION VII- PRECAUTIONS FOR SAFE HANDLING AND USE
Storage:
Store in a cool, well ventilated area. Elevated temperatures can result in shortened battery life.
Mechanical Containment:
Never seal or encapsulate nickel metal hydride batteries.
Do not obstruct safety release vents on batteries. Encapsulation (potting) of batteries will not allow cell venting
and can cause high pressure rupture.
Handling:
Accidental short circuit for a few seconds will not seriously affect the battery. However, this battery is capable of
delivering very high short circuit currents. Prolonged short circuits will cause high cell temperatures which can
cause skin burns. Sources of short circuits include jumbled batteries in bulk containers, metal jewelry, and metal
covered tables or metal belts used for assembly of batteries into devices.
Do not open battery. The negative electrode material may be pyrophoric. Should an individual cell from a battery
become disassembled, spontaneous combustion of the negative electrode is possible. This is much more likely to
happen if the electrode is removed from its metal container. There can be a delay between exposure to air and
spontaneous combustion.
