________________________________________________________________________
Flash Point and Method Used: N/A
Auto-Ignition Temperature: N/A
Flammability Limits in Air (% by Volume): N/A
LEL: N/A UEL: N/A
Extinguisher Media: Water only, no dry chemical, carbon dioxide or halon (MN-02).
Special Fire Fighting Procedures: Move container from fire area if you can do it without
risk. Apply cooling water to sides of container exposed to flames until well after
fire is out. For massive fire in cargo area, use unmanned hose holder or monitor
nossles; if this is impossible, withdraw from area and let fire burn. Flood with
water. Cool containers with flooding amounts of water from as far a distance as
possible. Avoid breathing vapors or dusts. Evacuate to a radius of 2500 feet for
uncontrollable fire. Fire fighters should wear proper protective equipment and
self-contained breathing apparatus with full facepiece operated in the positive
pressure mode.
Unusual Fire and Explosion Hazards: Negligible fire hazard when exposed to heat or
flame. Oxidizer: Oxidizers decompose, especially when heated, to yield oxygen
or other gases which will increase the burning rate of combustible matter.
Contact easily oxidizable, organic, or other combustible materials may result in
ignition, violent combustion or explosion.
Toxic gases produced: Sulfur dioxide (Na2SO4).

TOXICITY:
Manganese Dioxide: 45 mg/kg intravenous-rabbit LDLO; 422 mg/kg subcutan-
euous-mouse LD50; reproductive effects data (RTEC).
Sodium Sulfate: LD50 (oral-mouse) 5989 mg/kg.
HEALTH HAZARDS - Acute:
Inhalation: See information on metal fume fever and manganese compounds.
Other effects of manganese compounds may include acute bronchitis,
nasopharyngitis, and pneumonia. Reproductive effects have been
reported in animals.
METAL FUME FEVER: Acute exposure: Metal fume fever, an influ-
enza-like illness, may occur due to the inhalation of freshly formed metal
oxide particles sized below 1.5 microns and usually between 0.02-0.05
microns. Symptoms may be delayed 4-12 hours and begin with sudden
onset of thirst, and a sweet metallic or foul taste in the mouth. Other
symptoms may include upper respiratory tract irritation accompanied by
coughing and a dryness of the mucous membranes, lassitude and a
generalized feeling of malaise. Fever, chills, muscular pain, mild to
severe headache, nausea, occasional vomiting, exaggerated mental activity
profuse sweating, excessive urination, diarrhea and prostration may also
occur. Tolerance to fumes develops rapidly, but is quickly lost. All
symptoms usually subside within 24-36 hours.
May cause irritation to the upper respiratory tract (Na2SO4).
Ingestion: Abdominal pain, nausea (MN-02); May cause gastrointestinal
irritation. (Na2SO4)
3
Skin Contact: May cause irritation with redness and pain.
Eye Contact: May cause redness, pain, tearing and irritation.
HEALTH HAZARDS - Chronic:
Inhalation: There is no form of chronic metal fume fever, however, repeated
bouts with symptoms as described above are quite common. Resistance to
the condition develops after a few days of exposure, but is quickly lost in
1-2 days (MN-02).
Skin Contact: Repeated and prolonged contact may cause dermatitis.
Eye Contact: Repeated and prolonged contact may cause conjunctivitis.
Signs and Symptoms of Exposure: See above.
Medical Conditions Generally Aggravated by Exposure: N/A
EMERGENCY FIRST AID PROCEDURES - Seek medical assistance for further
treatment, observation and support if necessary.
Inhalation: If a person breathes in large amounts, move the exposed person
to fresh air. Get medical attention.
Ingestion: Treat symptomatically and supportively. Get medical attention
immediately.
Skin Contact: Remove contaminated clothing and shoes immediately. Wash
effected area with soap or mild detergent and large amounts of water
for at least 15 minutes or until no evidence of chemical remains. Get
medical attention immediately.
Eye Contact: Immediately flush with plenty of water for at least 15 minutes,
lifting upper and lower eyelids occasionally, until no evidence of chemical
remains. Get medical attention immediately.
