Hazards and Protection.
Storage
Keep tightly closed. Keep away from heat, sparks, and open flame. Store in a cool dry place.
Protection
Rubber gloves. Chemical safety goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
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.

Fire.
Flash Point,°C
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.
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.
Combustion products
Fire will produce irritating, corrosive and/or toxic gases.

Health.
Exposure effects
Flammable. Irritant. Irritating to eyes, respiratory system and skin.
   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.

First aid
 
   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.
