Diamond	Hazard	Value	Description
3 2 0	Health	2	Can cause temporary incapacitation or residual injury.
	Flammability	3	Can be ignited under almost all ambient temperature conditions.
	Instability	0	Normally stable, even under fire conditions.
	Special

A colorless liquid with a sharp pungent odor. Soluble in water and floats on water. Moderately toxic by ingestion and is an irritant to eyes and skin. Used in the chemical process industry.

• Highly Flammable

Highly flammable and soluble in water.

Special Hazards of Combustion Products: Irritating vapors and toxic gases, such as carbon dioxide and carbon monoxide, may be formed when involved in fire.

Behavior in Fire: Flashback along vapor trail may occur. (USCG, 1999)

Exposure can cause irritation of eyes, nose and throat. (USCG, 1999)

METHALLYL ALCOHOL may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas.

• Alcohols and Polyols
• Hydrocarbons, Aliphatic Unsaturated

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

• Cellulose-Based Absorbents
• Dirt/Earth

Excerpt from 129 [Flammable Liquids (Water-Miscible / Noxious)]:

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

LARGE SPILL: Consider initial downwind evacuation for at least 300 meters (1000 feet).

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)

Fire Extinguishing Agents Not to Be Used: Water.

Fire Extinguishing Agents: Dry chemical, alcohol foam, or carbon dioxide. (USCG, 1999)

Excerpt from 129 [Flammable Liquids (Water-Miscible / Noxious)]:

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. 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.

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)

Full impervious protective clothing, including boots and gloves. Where splashing is possible wear full face shield or chemical safety goggles. Use approved respirator to protect against vapors. (USCG, 1999)

Get medical attention.

INHALATION: Remove to fresh air. If breathing has stopped, give artificial respiration. If breathing is difficult, give oxygen.

EYES: Flush with water for at least 15 min., lifting lids occasionally.

SKIN: Remove contaminated clothing and shoes. Flush with water. (USCG, 1999)
