TRIISOBUTYL ALUMINUM

Diamond	Hazard	Value	Description
4 3 3 W	Health	3	Can cause serious or permanent injury.
	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	W	Reacts violently or explosively with water.

A colorless liquid.

• Strong Reducing Agent
• Water-Reactive
• Pyrophoric

Pyrophoric. Reacts violently with water producing flammable gas [Rose 1961].

Special Hazards of Combustion Products: Dense smoke may cause metal-fume fever.

Behavior in Fire: Dense smoke of aluminum oxide forms. (USCG, 1999)

Inhalation of smoke from fire causes metal-fume fever (flu-like symptoms). Contact with liquid can cause severe burns of eyes and skin because of spontaneous ignition. (USCG, 1999)

TRIISOBUTYL ALUMINUM reacts violently with alcohols, phenols, amines, carbon dioxide, sulfur oxides, nitrogen oxides, halogens, and halogenated hydrocarbons, causing fire and explosion hazards [Handling Chemicals Safely 1980. p. 937].

• Metal Hydrides, Metal Alkyls, Metal Aryls, and Silanes

Excerpt from ERG Guide 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 tank car or highway tank 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, 2024)

Fire Extinguishing Agents Not to Be Used: Water, foam, halogenated extinguishing agents

Fire Extinguishing Agents: Inert powder (e.g., sand, limestone), dry chemical (USCG, 1999)

Excerpt from ERG Guide 135 [Substances - Spontaneously Combustible]:

ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. Do not touch or walk through spilled material. Stop leak if you can do it without risk.

SMALL SPILL: CAUTION: For spills of Xanthates, UN3342 and for Dithionite (Hydrosulfite/Hydrosulphite), UN1384, UN1923 and UN1929, dissolve in 5 parts water and collect for proper disposal. CAUTION: UN3342 when flooded with water will continue to evolve flammable Carbon disulfide/Carbon disulphide vapors. Cover with DRY earth, DRY sand or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain. Use clean, non-sparking tools to collect material and place it into loosely covered plastic containers for later disposal. Prevent entry into waterways, sewers, basements or confined areas. (ERG, 2024)

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 lasts less than 36 hrs. and is not critical.

EYES: flush gently with copious quantities of water for 15 min. with lids open; treat burns, if fire occurred; get medical attention.

SKIN: wash with water; treat burns caused by fire; get medical attention.
