3 - Hazards Identification
SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT
Highly flammable. Very toxic by inhalation, in contact with skin
and if swallowed. Contact with acids liberates very toxic gas.
Causes burns. Very toxic to aquatic organisms, may cause long-term
adverse effects in the aquatic environment.
4 - First Aid Measures
AFTER INHALATION
If inhaled, remove to fresh air. If not breathing give
artificial respiration. If breathing is difficult, give oxygen.
AFTER SKIN CONTACT
In case of skin contact, flush with copious amounts of water for
at least 15 minutes. Remove contaminated clothing and shoes.
Call a physician.
AFTER EYE CONTACT
In case of contact with eyes, flush with copious amounts of
water for at least 15 minutes. Assure adequate flushing by
separating the eyelids with fingers. Call a physician.
AFTER INGESTION
If swallowed, wash out mouth with water provided person is
conscious. Call a physician immediately. Do not induce vomiting.
5 - Fire Fighting Measures
EXPLOSION DATA
Dust Potential: This material, like most materials in powder
form, is capable of creating a dust explosion.
EXTINGUISHING MEDIA

Unsuitable: Do not use water.
SPECIAL RISKS
Specific Hazard(s): Flammable solid. Contact with other material
may cause fire. Emits toxic fumes under fire conditions.
Explosion Hazards: Material readily reacts with water generating
flammable and/or explosive hydrogen gas
SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS
Wear self-contained breathing apparatus and protective clothing
to prevent contact with skin and eyes.
6 - Accidental Release Measures
PERSONAL PRECAUTION PROCEDURES TO BE FOLLOWED IN CASE OF LEAK OR SPILL
Evacuate area. Shut off all sources of ignition. Use nonsparking
tools.
PROCEDURE(S) OF PERSONAL PRECAUTION(S)
Wear self-contained breathing apparatus, rubber boots, and heavy
rubber gloves.
METHODS FOR CLEANING UP
Cover with dry-lime, sand, or soda ash. Place in covered
containers using non-sparking tools and transport outdoors.
Avoid raising dust. Carefully sweep up and remove. Ventilate
area and wash spill site after material pickup is complete.
7 - Handling and Storage
HANDLING
Directions for Safe Handling: Do not breathe dust. Do not get in
eyes, on skin, on clothing. Avoid all contact. Open carefully.
STORAGE
Conditions of Storage: Keep tightly closed. Keep away from heat,
sparks, and open flame.

11 - Toxicological Information
SIGNS AND SYMPTOMS OF EXPOSURE
Material is extremely destructive to tissue of the mucous
membranes and upper respiratory tract, eyes, and skin.
Inhalation may result in spasm, inflammation and edema of the
larynxand bronchi, chemical pneumonitis, and pulmonary edema.
May be fatal. Symptoms of exposure may include burning
sensation, coughing, wheezing, laryngitis, shortness of breath,
headache, nausea, and vomiting. To the best of our knowledge,
the chemical, physical, and toxicological properties have not
been thoroughly investigated. Absorption into the body leads to
the formation of methemoglobin which in sufficient concentration
causes cyanosis. Onset may be delayed 2 to 4 hours or longer.
ROUTE OF EXPOSURE
Skin Contact: Causes burns.
Skin Absorption: May be fatal if absorbed through skin.
Eye Contact: Causes burns.
Inhalation: May be fatal if inhaled. Material is extremely
destructive to the tissue of the mucous membranes and upper
respiratory tract.
Ingestion: May be fatal if swallowed.
TARGET ORGAN INFORMATION
Blood.
12 - Ecological Information
No data available.
13 - Disposal Considerations
SUBSTANCE DISPOSAL
Contact a licensed professional waste disposal service to dispose
of this material. Burn in a chemical incinerator equipped with an
afterburner and scrubber but exert extra care in igniting as this
material is highly flammable. Observe all federal, state, and
local environmental regulations.
