Hazards and Protection.
Storage
Store in a cool, dry, well-ventilated area away from incompatible substances. Keep containers tightly closed.
Handling
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Use only in a chemical fume hood. Do not breathe dust.
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 protective gloves and clothing to prevent skin exposure. Clothing: Wear appropriate protective 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
Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Provide ventilation.
Stability
Stable under normal temperatures and pressures. Dusts may form an explosion hazard. Boiling with Potassium hydroxide yields a product that, after drying, explodes at 205 C or when mixed with combustible materials.
Incompatibilities
Alkalies, potassium hydroxide.
Decomposition
Hydrogen chloride, nitrogen oxides, ammonia and/or derivatives, nitrogen, chloride fumes.

Fire.
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. To extinguish fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
Fire potential
Non-Combustible
Combustion products
Toxic gases and vapors (such as chlorine) may be released when chlorine-containing soluble platinum salts decompose.

Exposure effects
Repeated exposure may cause sensitization dermatitis. Chronic inhalation may cause pulmonary emphysema. Chronic inhalation may cause pulmonary fibrosis.
   Ingestion
Harmful if swallowed. May cause gastrointestinal irritation with nausea, vomiting and diarrhea.
   Inhalation
May be fatal if inhaled. May cause pulmonary fibrosis and permanent damage. May cause respiratory sensitization. Symptoms include asthma, sneezing, coughing, bronchitis, tightness of chest, and irritation of nose and throat.
   Skin
May cause irritation and dermatitis. May cause sensitization by skin contact.
   Eyes
Causes eye irritation. Lachrymator. Causes redness of eyes and swelling of eyelids.

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. Wash clothing before reuse.
   Eyes
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
