ETHYL ALUMINUM DICHLORIDE

Diamond	Hazard	Value	Description
4    3	Health
	Flammability	4	Burns readily. Rapidly or completely vaporizes at atmospheric pressure and normal ambient temperature.
	Instability	3	Capable of detonation or explosive decomposition or explosive reaction but requires a strong initiating source or must be heated under confinement before initiation.
	Special

A colorless to light-yellow heated liquid. Freezing point 90°F. (USCG, 1999)

• Strong Reducing Agent
• Water-Reactive
• Pyrophoric

Highly flammable. Ignites when exposed to air. Reacts violently with water or moisture in air forming hydrogen chloride fumes and flammable ethane gas (Rose 1961).

Special Hazards of Combustion Products: Intense smoke may cause metal-fume fever. Irritating hydrogen chloride also formed.

Behavior in Fire: Contact with water applied to adjacent fires will cause formation of irritating smoke containing aluminum oxide and hydrogen chloride. (USCG, 1999)

Inhalation of smoke from fire causes metal-fume fever (flu-like symptoms); acid fumes irritate nose and throat. Contact with liquid (which is spontaneously flammable) causes severe burns of eyes and skin. (USCG, 1999)

Organometallics, such as ETHYL ALUMINUM DICHLORIDE, are reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents. Often reactive with water to generate toxic or flammable gases. Organometallics containing halogens (fluorine, chlorine, bromine, iodine) bonded to the metal typically with generate gaseous hydrohalic acids (HF, HCl, HBr, HI) with water.

Excerpt from 135 [Substances - Spontaneously Combustible]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

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)

Fire Extinguishing Agents Not to Be Used: Water, foam, dry chemicals, halogenated agents, or carbon dioxide

Fire Extinguishing Agents: Inert dry powders such as dry graphite, soda ash, sand, limestone. (USCG, 1999)

Neutralizing Agents for Acids and Caustics: Rinse with sodium bicarbonate or lime solution. (USCG, 1999)

Full protective clothing, preferably of aluminized glass cloth; goggles, face shield, gloves; in case of fire, all-purpose canister or self-contained breathing apparatus. (USCG, 1999)

No information available.

INHALATION: only fumes from fire need be considered; metal-fume fever is not critical and lasts less than 36 hrs.; irritation of nose and throat by acid vapors may require treatment by a physician.

EYES: flush gently with water for 15 min.; treat burns if fire occurred; get medical attention.

SKIN: wash with water; treat burns caused by fire; get medical attention. (USCG, 1999)
