Alcohols and Polyols

An unsaturated aliphatic/alcohol. The unsaturated aliphatic hydrocarbons are generally much more reactive than the alkanes, which are saturated aliphatic hydrocarbons. Strong oxidizers may react vigorously with them. Reducing agents can react exothermically to release gaseous hydrogen. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

380 °C

The vapour mixes well with air, explosive mixtures are easily formed.

Fire Extinguishing Agents Not to Be Used: Water may be ineffective. Fire Extinguishing Agents: Carbon dioxide, dry chemical, alcohol foam. (USCG, 1999)|Use carbon dioxide, dry powder. In case of fire: keep drums, etc., cool by spraying with water.

Excerpt from ERG Guide 127 [Flammable Liquids (Water-Miscible)]: As an 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, 2016)

Excerpt from ERG Guide 127 [Flammable Liquids (Water-Miscible)]: ELIMINATE all ignition sources (no smoking, flares, sparks or flames in 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, 2016)

Self-contained breathing apparatus, rubber boots and heavy rubber gloves. (USCG, 1999)

Explosive limits , vol% in air: 1.5 - 9.4

Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.

Fireproof. Separated from oxidants. Well closed. Ventilation along the floor. Store in an area without drain or sewer access.

No indication can be given about the rate at which a harmful concentration of this substance in the air is reached.

The substance is irritating to the eyes.

NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools.

Use ventilation.

Protective gloves.

Wear safety spectacles.

Harmful if inhaled or swallowed. Material is irritating to mucous membrane and upper respiratory tract. (USCG, 1999)

INHALATION: Call for medical aid. Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. EYES: Flush with copious amounts of water for at least 15 minutes. SKIN: Wash with soap and copious amounts of water. (USCG, 1999)

Fresh air, rest.

Rinse skin with plenty of water or shower.

Rinse with plenty of water (remove contact lenses if easily possible).
