What is Silane?

Silane is a colorless, flammable, and poisonous gas. It is easily ignited in air, reacts with oxidizing agents, is very toxic by inhalation and is a strong irritant to skin, eyes, and mucous membranes. Silane is lighter than air. When heated under pressure or exposed to fire, containers of silane may rupture violently and rocket. Fumes produced by burning silane are toxic.

Silane Exposure and Health Risks

Silane is very toxic by inhalation and is a strong irritant to skin, eyes, and mucous membranes. Inhalation can cause respiratory irritation and difficulty breathing. Repeated or prolonged exposure to silane causes damage to organs. Direct contact can cause burns, severe injury, and/or frostbite.
