Hazards Summary · 1 item

Reacts with water and moisture evolving flammable gases (may be violent and ignite on contact); Highly flammable and a strong reducing agent; [CAMEO] Causes spastic paralysis and dyspnea in lethal-dose studies of rabbits, rats, and mice (dermal, inhalation, and oral routes); [RTECS] Reacts violently with water (may form flammable or combustible mixture); A flammable reducing agent; May form explosive mixtures with air; Causes burns to skin and eyes; Dust is irritating to eyes and respiratory tract; Harmful by ingestion and inhalation; [Kodak MSDS]

DOT ID and Guide1870 138
Reactive GroupMetal Hydrides, Metal Alkyls, Metal Aryls, and Silanes
Reactivity AlertsStrong Reducing Agent
Reactivity ProfileA reducing agent. Reacts rapidly and dangerously with oxygen and with other oxidizing agents, even weak ones. Thus, they are likely to ignite on contact with alcohols. Hydrides are incompatible with acids, alcohols, amines, and aldehydes.
