ALLYL BROMIDE

Diamond	Hazard	Value	Description
3 3 1	Health	3	Can cause serious or permanent injury.
	Flammability	3	Can be ignited under almost all ambient temperature conditions.
	Instability	1	Normally stable but can become unstable at elevated temperatures and pressures.
	Special

A clear colorless to light yellow liquid with an irritating unpleasant odor. Flash point 30°F. Irritates eyes, skin, and respiratory system. Toxic by skin absorption. Denser than water and slightly soluble in water.

• Highly Flammable
• Polymerizable
• Strong Reducing Agent

Highly flammable. Slightly soluble in water.

Special Hazards of Combustion Products: Toxic hydrogen bromide and bromine gases formed in fire.

Behavior in Fire: Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back. (USCG, 1999)

Inhalation of vapor irritates mucous membranes and causes dizziness, headache, and lung irritation. Contact with liquid irritates eyes and skin. Ingestion causes irritation of mouth and stomach. (USCG, 1999)

ALLYL BROMIDE decomposes upon heating and exposure to light, forming HBr (a strong reducing agent). Reacts violently with oxidizing agents. Can react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions.

• Halogenated Organic Compounds
• Hydrocarbons, Aliphatic Unsaturated
• Polymerizable Compounds

Use caution: Liquids with this reactive group classification have been known to react with the absorbents listed below.

• Mineral-Based & Clay-Based Absorbents
• Dirt/Earth

Excerpt from 131 [Flammable Liquids - Toxic; polymerization hazard]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters (150 feet) in all directions.

SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.

FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2020)

Excerpt from 131 [Flammable Liquids - Toxic; polymerization hazard]:

CAUTION: The majority of these products have a very low flash point. Use of water spray when fighting fire may be inefficient. CAUTION: Methanol (UN1230) will burn with an invisible flame. Use an alternate method of detection (thermal camera, broom handle, etc.).

SMALL FIRE: Dry chemical, CO2, water spray or alcohol-resistant foam.

LARGE FIRE: Water spray, fog or alcohol-resistant foam. If it can be done safely, move undamaged containers away from the area around the fire. Dike runoff from fire control for later disposal. Avoid aiming straight or solid streams directly onto the product.

FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2020)

Excerpt from 131 [Flammable Liquids - Toxic; polymerization hazard]:

ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. A vapor-suppressing foam may be used to reduce vapors.

SMALL SPILL: Absorb with earth, sand or other non-combustible material and transfer to containers for later disposal. Use clean, non-sparking tools to collect absorbed material.

LARGE SPILL: Dike far ahead of liquid spill for later disposal. Water spray may reduce vapor, but may not prevent ignition in closed spaces. (ERG, 2020)

Goggles and face shield; protective clothing; self-contained breathing appartus for high vapor concentrations. (USCG, 1999)

No information available.

INHALATION: remove from exposure; if not breathing, give artificial respiration; if breathing is difficult, give oxygen; call physician.

EYES: flush with water for at least 15 min. and call physician.

SKIN: flush with water; get medical attention for skin irritation.

INGESTION: do NOT induce vomiting; get medical attention. (USCG, 1999)
