Section IV - Fire and Explosion Hazard Data
Flash point: NA Lower Explosive Limit: NA Upper Explosive Limit: NA
Extinguishing Media: Any class of extinguishing medium may be used on the batteries or
their packing material.
Special Fire Fighting Procedures: Exposure to temperatures of above 212°F can cause
evaporation of the liquid content ofthe potassium hydroxide electrolyte resulting in the rupture of
the cell. Potential for exposure to cadmium fumes during fire;use self-contained breathing apparatus.
Section V - Health Hazard Data
Threshold Limit Values: See Section II
Effects of a Single (Acute) Overexposure:
Inhalation:
During normal use inhalation is an unlikely route of exposure due to containment
of hazardous materials within thebattery case. However, should the batteries be exposed to
extreme heat or pressures causing a breach in the battery cell case,cadmium dusts and fumes may
be emitted. Inhalation of cadmium dusts or fumes may causethroat dryness, respiratory
irritation, headache, nausea, vomiting, chest pain, extreme restlessness and irritability, pneumonitis,and
bronchopneumonia. In the case of high concentration exposures (e.g., above 1 to 5 mg/m
3
duringan eight
hour period) death may occur within several days after the exposure.
Ingestion:
If the battery case is breached in the digestive tract, the electrolyte may cause
localized burns. Ingestion ofcadmium compounds may result in increased salivation, choking,
nausea, persistent vomiting, diarrhea, abdominal pain, anemia, tenesmus, and kidney dysfunction.
Skin Absorption:
No evidence of adverse effects from available data.
Skin Contact:
Exposure to the electrolyte contained inside the battery may result in chemical burns.
Exposure to nickel may causedermatitis in some sensitive individuals.
Eye Contact:
Exposure to the electrolyte contained inside the battery may result in severe
irritation and chemical burns.
Carcinogenicity:
Cadmium and nickel have been identified by the National Toxicology Program (NTP) as
reasonably anticipated to be carcinogens. U.S. EPA classified cadmium as a "B1" probable human
carcinogen. The International Agency for Research on Cancer (IARC) recommended that cadmium be
listed as a "2A" probable human carcinogen, and the American Conference of Governmental
Industrial Hygienists (ACGIH) has proposed listing cadmium as an A2 carcinogen.
