First Aid Measures

Ingestion
Seek medical assistance.
Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
Skin
Remove and isolate contaminated clothing and shoes. Remove material from skin immediately. Immediately flush with running water for at least 20 minutes.
Eyes
Immediately flush with running water for at least 20 minutes.

Handling and Storage

Storage
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.

Hazards Identification

Ingestion
See Inhalation.
Inhalation
May cause severe injury or burns.
Skin

Exposure Controls/Personal Protection

Personal Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).

Fire Fighting Measures

Flash Point
50 kJ/mol
Fire Fighting
The temperature of the substance must be maintained at or below the Control Temperature at all times. Small Fires: Water spray or fog is preferred; if water not available use dry chemical, carbon dioxide or regular foam. Large Fires: Flood fire area with water from a distance. Use water spray or fog; do not use straight streams.
Fire Potential
May explode from heat, contamination or loss of temperature control. Particularly sensitive to temperature rises.

Accidental Release Measures

Small spills/leaks
ELIMINATE all ignition sources and combustible materials. Do not touch spilled material. Stop leak if you can do it without risk. Take up with inert, damp, noncombustible material using clean non-sparking tools and place into loosely covered plastic containers for later disposal. For large spills, contact specialist for clean-up or disposal instructions.

Stability and Reactivity

Stability
No data.
Combustion Products
Fire may produce irritating, corrosive and/or toxic gases.
