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

Keep tightly closed. Keep away from heat, sparks, and open flame. Store in a cool dry place.

Hazards Identification

Inhalation

Vapors may cause dizziness or suffocation. May cause toxic effects. May irritate or burn.

Skin

May irritate or burn. May cause toxic effects if absorbed through the skin.

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

Rubber gloves. Chemical safety goggles.

Respirators

Wear positive pressure self-contained breathing apparatus (SCBA).

Exposure Effects

Flammable. Irritant. Irritating to eyes, respiratory system and skin.

Fire Fighting Measures

Flash Point

22

Fire Fighting

Extinguish using Carbon dioxide, dry chemical powder, or appropriate foam. Unsuitable: Water may be effective for cooling, but may not effect extinguishment. Wear self-contained breathing apparatus and protective clothing to prevent contact

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

Stable at normal temperatures and pressures.

Incompatibilities

Strong oxidizing agents, Strong bases.

Decomposition

Carbon monoxide, Carbon dioxide, Hydrogen bromide gas.

Combustion Products

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