W
Blue Health 3 Can cause serious or permanent injury.
Red Flammability 4 Burns readily. Rapidly or completely vaporizes at atmospheric pressure and normal ambient temperature.
Yellow 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.
White Special W Reacts violently or explosively with water.
(NFPA, 2010)
General Description
A clear colorless liquid. Not a single compound ("alkyl" refers to a family of substitutent groups). Most probably either trimethyl aluminum or triethyl aluminum.

Hazards

Reactivity Alerts
Air & Water Reactions
Highly flammable. May ignite upon contact with air producing aluminum oxide fumes. Reacts violently with water to give aluminum oxide and alkanes (flammable hydrocarbons).
Fire Hazard
No information available.
Health Hazard
No information available.
Reactivity Profile
ALUMINUM ALKYLS are strong reducing agents. React violently with water, alcohols, phenols, amines, carbon dioxide, sulfur oxides, nitrogen oxides, halogens, and halogenated hydrocarbons, creating fire and explosion hazards [Handling Chemicals Safely 1980. p. 929].
