First Aid Measures

Ingestion
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.
Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Skin
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Eyes
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.

Handling and Storage

Storage
Store in a cool, dry place. Keep container closed when not in use. Store in a tightly closed container. Store below 40C. Store protected from light.
Handling
Wash thoroughly after handling. Use only in a well ventilated area. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation.

Hazards Identification

Ingestion
May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns.
Inhalation
Irritation may lead to chemical pneumonitis and pulmonary edema. May cause severe irritation of the respiratory tract with sore throat, coughing, shortness of breath and delayed lung edema.
Skin
May cause severe skin irritation.

Fire Fighting Measures

Flash Point
127
Autoignition
> 130
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Dusts at sufficient concentrations can form explosive mixtures with air. To extinguish fire, use water fog, dry chemical, carbon dioxide, or regular foam.
Fire Potential
This chemical is combustible.

Accidental Release Measures

Small spills/leaks
Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Avoid generating dusty conditions.

Stability and Reactivity

Incompatibilities
Oxidizing agents.
Stability
Stable under normal temperatures and pressures.
Decomposition
Carbon monoxide, carbon dioxide.
