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 heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Flammables-area.

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

May cause irritation or burns.

Skin

See Inhalation.

Eyes

See Inhalation.

Ingestion

Nausea, vomiting, and diarrhea are common. Gastrointestinal hemorrhage can occur.

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

46

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

Incompatibilities

Acids, strong oxidizing agents.

Stability

Stable under normal temperatures and pressures.

Decomposition

Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide.

Combustion Products

Fire may produce irritating, corrosive and/or toxic gases.
