Hazards and Protection.
Storage
Keep away from heat, sparks, and flame. Do not store near combustible materials. Keep away from acids. Keep away from reducing agents. Keep containers tightly closed. Store in a cool, dry area away from incompatible substances.
Handling
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Do not get in eyes, on skin, or on clothing. Do not ingest or inhale. Use only in a chemical fume hood. Keep away from clothing and other combustible materials. Discard contaminated shoes.
Protection
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate gloves to prevent skin exposure. Clothing: Wear a chemical apron. Wear appropriate clothing to prevent skin exposure.
Respirators
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.
Small spills/leaks
Wash area with soap and water. Clean up spills immediately, using the appropriate protective equipment. Cover with sand, dry lime or soda ash and place in a closed container for disposal. Provide ventilation. Keep combustibles (wood, paper, oil, etc.,) away from spilled material.
Stability
Stable under normal temperatures and pressures.
Incompatibilities
Strong reducing agents, strong acids, cyanides (e.g. potassium cyanide, sodium cyanide), thiocyanates, isocyanates, hypophosphites, organic matter, phosphinates + heat, aluminum powder + water + metal nitrate may explode, mixtures of metal nitrates with alkyl esters may explode.
Decomposition
Oxides of nitrogen.

Fire.
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Water runoff can cause environmental damage. Dike and collect water used to fight fire. Strong oxidizer. Contact with combustible materials may cause a fire. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water with caution and in flooding amounts. Extinguishing media: Use water only! Contact professional fire-fighters immediately. DO NOT use dry chemicals, carbon dioxide, Halon or foams.
Fire potential
These substances will accelerate burning when involved in a fire.
Hazards
May explode from heat or contamination. May react explosively with hydrocarbons (fuels). May ignite combustibles.
Combustion products
Fire may produce irritating, corrosive and/or toxic gases.

Health.
Exposure effects
   Ingestion
May cause severe irritation of the digestive tract. May cause nausea, vomiting, and diarrhea, possibly with blood.
   Inhalation
Dust is irritating to the respiratory tract. Causes irritation of the mucous membrane. May cause acute pulmonary edema, asphyxia, chemical pneumonitis, and upper airway obstruction caused by edema.
   Skin
Causes skin irritation. May cause severe irritation and possible burns.
   Eyes
Causes eye irritation. May cause conjunctivitis. May cause permanent corneal opacification.

First aid
 
   Ingestion
Never give anything by mouth to an unconscious person. Get medical aid immediately. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
   Inhalation
Get medical aid immediately. Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. Do not use mouth-to-mouth respiration if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device.
   Skin
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
   Eyes
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
