Hazards and Protection.
Store in a cool, dry, well-ventilated area away from incompatible substances.
Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with skin and eyes. Avoid ingestion and inhalation.
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 appropriate protective clothing to minimize contact with skin.

Stable under normal shipping and handling conditions.
Can react dangerously with acids, caustic alkalies, and strong oxidizing agents.
Nitrogen oxides, carbon monoxide, carbon dioxide, ammonia and/or derivatives.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Use extinguishing media appropriate to the surrounding fire. Substance is noncombustible. Extinguishing media: Substance is noncombustible; use agent most appropriate to extinguish surrounding fire.
Containers may explode when heated.
Irritating and toxic ammonia gas may form in fires.
Increases in blood pressure and pulse have been reported. An altered mental status (coma) may be seen, but is not characteristic unless hypoxemia occurs. Seizures may occur with extensive absorption. No data were available to assess the teratogenic potential of this agent. <br>Decreased egg production has occurred in experimental animals. Ammonia crosses the ovine placental barrier. <br>No data were available to assess the potential effects of exposure to this agent during lactation. <br>No information about possible male reproductive effects was found in available references.
Ingestion of large amounts may cause gastrointestinal irritation. Expected to be a low ingestion hazard.
Low hazard for usual industrial handling. Excessive inhalation may cause minor respiratory irritation.
May cause mild skin irritation. Low hazard for usual industrial handling.
May cause mild eye irritation.
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid.
Remove from exposure to fresh air immediately. Get medical aid if cough or other symptoms appear.
