First Aid Measures

Ingestion
Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid. May cause irritation of the digestive tract and possible burns.
Inhalation
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. DO NOT use mouth-to-mouth respiration.
Skin
Get medical aid. 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.

Handling and Storage

Storage
Keep from contact with oxidizing materials. Keep away from acids. Store in a cool, dry area away from incompatible substances.
Handling
Wash thoroughly after handling. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with skin and eyes. Keep container tightly closed.

Hazards Identification

Exposure Controls/Personal Protection

Personal 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 clothing to minimize contact with skin. Clothing: Wear appropriate protective clothing to minimize contact with skin.
Respirators
A NIOSH/MSHA approved air purifying dust or mist respirator or European Standard EN 149.
Exposure Effects
Effects may be delayed.
Exposure limit(s)

Poison Class
3

Fire Fighting Measures

Flash Point
500
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. Extinguishing media: For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam.

Accidental Release Measures

Small spills/leaks
Vacuum or sweep up material and place into a suitable disposal container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation.

Stability and Reactivity

Incompatibilities
Acids, methanoic acid, oxalic acid), strong oxidizing agents.
Stability
Stable under normal temperatures and pressures.
Decomposition
Carbon monoxide, oxides of nitrogen, oxides of sulfur, carbon dioxide, cyanide fumes.
