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. Wash skin with soap and water. Flush with running water for at least 20 minutes
Eyes
Flush with running water for at least 20 minutes.

Handling and Storage

Storage
Keep away from sources of ignition. Store in a tightly closed container. Store in a dry area. Refrigerator at 4 C.
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

Inhalation
Vapors may cause dizziness or suffocation. May cause irritation or burns.
Skin
May cause irritation or burns.
Eyes
See Skin.
Hazards
Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers.

Fire Fighting Measures

Flash Point
-34
Fire Fighting
Use of water spray when fighting fire may be inefficient. Small Fires: Dry chemical, carbon dioxide, water spray or alcohol-resistant foam. Large Fires: Water spray, fog or alcohol-resistant foam. Use water spray or fog; do not use straight streams.
Fire Potential
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.

Accidental Release Measures

Small spills/leaks
Make no contact with the spilled material. ELIMINATE all ignition sources and ground all equipment. Stop leak if you can do it without risk. A vapor suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean non-sparking tools to collect absorbed material.

Stability and Reactivity

Stability
No data.
Incompatibilities
Strong oxidizing agents, strong acids.
Decomposition
Carbon monoxide, carbon dioxide.
Combustion Products
Fire may produce irritating, corrosive and/or toxic gases.
