3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Black powder. Inhaling dust may irritate the upper respiratory tract, and may lead to
“metal fume fever,” a flu-like condition. Long term exposure by inhaling or swallowing
can affect the central nervous system or kidneys.
Will not burn in a fire but may increase the intensity of a fire involving other materials.
Use extinguishing media suitable for the materials that are burning.
POTENTIAL HEALTH EFFECTS
PRIMARY ROUTE(S) OF ENTRY
Inhalation (breathing)
-1-
MTI Corporation
Material Safety Data Sheet
CAUTION! Breathing dust may irritate the upper respiratory tract. Exposure to large quantities of
dust or fume may cause “metal fume fever.” Repeated or prolonged inhalation of the dust or fumes
may cause delayed injury to the central nervous system or kidneys.
SYMPTOMS OF EXPOSURE
Inhalation: There are no known studies or signs/symptoms for this material. However, salts of
manganese and lithium may cause the following: Flu-like symptoms - fever, chills,
nausea and vomiting, muscular aches, and weakness; coughing, sneezing, bronchitis
- can result from breathing high concentrations of dust or fume. Chronic exposure by
breathing low levels of dust or fume over a long time can result in “manganism”, a
disease of the central nervous system similar to parkinsonism. Prolonged or repeated
inhalation of lithium compounds can cause central nervous system or kidney
damage.
Eye Contact: Non-irritant
Skin Contact: Non-irritant
Ingestion: Similar to those listed for inhalation
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE
Eye, skin, respiratory, or kidney diseases or disorders would be aggravated by repeated or
prolonged exposure to the dust or fume from this chemical. Iron deficiency may increase
susceptibility to manganese poisoning.

4. FIRST AID MEASURES
Inhalation: Remove from area to fresh air. Seek medical attention if respiratory irritation
develops or if breathing becomes difficult.
Eye contact:
Rinse eyes with water. Remove any contact lenses, and continue flushing with
plenty of water for several minutes. Seek medical attention if irritation develops or
persists.
-2-
MTI Corporation
Material Safety Data Sheet
Skin Contact: Wash affected areas with plenty of water, and soap if available, for several minutes.
Seek medical attention if irritation develops or persists.
Ingestion:
Give 3-4 glasses of water, but DO NOT induce vomiting. If vomiting occurs, give
fluids again. Get medical attention to determine whether vomiting or evacuation of
stomach is necessary. Do not give anything by mouth to an unconscious or
convulsing person.
NOTE TO PHYSICIAN
Chemical of exposure is lithium manganese oxide. Acute exposure can result in metal fume fever.
Chronic exposure to dust can lead to manganism, a disease of the central nervous system,
characterized by psychic and neurological disorders. Overexposure to lithium compounds can cause
kidney damage.
5. FIRE FIGHTING MEASURES
Flash Point and Method.............N/A
GENERAL HAZARD
This product is not flammable, but may increase the intensity of a fire involving other materials,
and may release toxic manganese and lithium oxides.
EXTINGUISHING MEDIA
Use suitable media for the material that is burning.
SPECIAL FIREFIGHTING INSTRUCTIONS
Move containers from area if it can be done without risk.
FIREFIGHTING EQUIPMENT
Wear NIOSH approved, positive-pressure self-contained breathing apparatus and full protective
gear.
6. ACCIDENTAL RELEASE MEASURES
Wear appropriate protective equipment (See Section 8).
ON LAND
Shovel up material and place in suitable containers for later disposal.

IN WATER
Suction or dredge up into a chemically compatible container for disposal.
7. HANDLING AND STORAGE
HANDLING
Wear appropriate protective equipment (See Section 8).
STORAGE
Store in a cool dry place. Avoid contact with easily oxidized materials and flammable materials.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
ENGINEERING CONTROLS
Provide local exhaust and general ventilation system.
PERSONAL PROTECTION
Respirator: In operations where dusts are generated, use a NIOSH approved respirator that has
been selected by a technically qualified person for the specific work conditions.
Eye Protection: Wear safety glasses with side shield (or goggles).
Skin Protection: Wear rubber gloves and normal work clothing.
Other: Eye wash, washing facilities, safety shower

11. TOXICOLOGICAL INFORMATION
90 Day Inhalation Study ...................Three groups of female and male rates were exposed to 1, 4,
or 16 mg/m3 for 6 hours/day, five days/week over a 90-day exposure period. The Mass Median
Aerodynamic Diameters were 1.28-1.39 microns. No exposure-related deaths or signs of toxicity
were observed during the study. Increases in certain cell type counts were sometimes statistically
significant and are considered biologically relevant. These findings were consistent with, and
secondary to, microscopic observations of chronic inflammation in the lung and larynx.
This study established a No Observed Effect Level (NOEL) of 1 mg/m3, and a No Adverse Effect
Level (NOAEL) of 4 mg/m3 which was based on transient clinical and diagnostic pathology
findings at necropsy. These findings reflected a normal physiological response to pulmonary
particulate exposure which cleared at necropsy of animals that had been provided a 60-day
recovery period.
Dermal LD50 (rabbit) ........................>2,000 mg/kg. A limit test was performed on 10 rabbits at a
dose level of 2 g/kg; no animal died. Erythema (Grade 1 or 2), but
not edema, was noted in all animals.
Primary dermal irritation (rabbit) ........Non-irritant. A Primary
Irritation Index of 0 was determined after dosing 6 animals with 0.5 grams of the test substance for

animal treated with >0.1 g for 24 hours.
