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. In case of contact with substance, immediately flush with running water for at least 20 minutes. Wash skin with soap and water.
Eyes
In case of contact with substance, immediately flush with running water for at least 20 minutes.

Handling and Storage

Storage
Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Keep away from heat, sparks, and flame. Keep away from sources of ignition. Keep container closed when not in use. Store in a cool, dry, well-ventilated area away from incompatible substances. Flammables-area. Keep containers tightly closed.

Hazards Identification

Ingestion
May cause toxic effects.
Inhalation
Vapors may cause dizziness or suffocation. May cause toxic effects.
Skin
Contact with substance may cause severe 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.

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
2
Fire Fighting
Small Fires: Dry chemical, CO2, water spray or alcohol-resistant foam. Large Fires: Water spray, fog or alcohol-resistant foam.
Fire Potential
Flammable/combustible material. May be ignited by heat, sparks or flames.

Accidental Release Measures

Small spills/leaks
Make no contact with the spilled material. Fully encapsulating, vapor protective clothing should be worn for spills and leaks with no fire. 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

Incompatibilities
Acoid contact with strong oxidizing agents, acids, acid chlorides.
Stability
Stable under normal temperatures and pressures.
Combustion Products
Fire will produce irritating, corrosive and/or toxic gases.
