First Aid Measures

Ingestion
Induce vomiting. 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 immediately.
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
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 away from sources of ignition. Keep from contact with oxidizing materials. Store in a cool, dry, well-ventilated area away from incompatible substances.
Handling
Wash thoroughly after handling. Use with adequate ventilation. Avoid contact with skin and eyes. Avoid ingestion and inhalation.

Hazards Identification

Inhalation
Causes respiratory tract irritation.
Skin
Causes skin irritation. Chronic exposure may cause thyroid damage: thyroid enlargement, decrease in metabolic rate, and hypothyroidism.
Eyes
May cause moderate eye irritation.
Ingestion
Harmful if swallowed. Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May cause agitation, delerium, convulsions, and muscle

Exposure Controls/Personal Protection

Personal Protection
Eyes: Wear chemical goggles and a face shield if splashing is possible. Skin: Wear appropriate gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
Respirators
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Exposure Effects
Chronic exposure may cause thyroid damage: thyroid enlargement, decrease in metabolic rate, and hypothyroidism.
Poison Class
3

Fire Fighting Measures

Flash Point
190
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Dust can be an explosion hazard when exposed to heat or flame. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam.
Fire Potential
Solid may be combustible; solution is not flammable.

Accidental Release Measures

Small spills/leaks
Vacuum or sweep up material and place into a suitable disposal container. Avoid generating dusty conditions. Remove all sources of ignition.

Incompatibilities
Can explode if mixed with lead nitrate. Reacts dangerously with chlorates, nitrates, nitric acid, organic peroxides, oxidizing agents, peroxides, potassium chlorate, and sodium chlorate.
Stability
Stable under normal shipping and handling conditions.
Decomposition
Hydrogen cyanide, nitrogen oxides, carbon monoxide, oxides of sulfur, carbon dioxide, ammonia and/or derivatives.
Combustion Products
Decomposes to form ammonia, hydrogen sulfide, and hydrogen cyanide.
