Safety Data

Hazard F:Flammable
Risk R11
Safety

A nuisance dust. Moderately toxic by ingestion. An eye irritant. Does not occur freely in nature, but is found as silicon dioxide (silica) and as various silicates. Elemental Si is flammable when exposed to flame or by chemical reaction with oxidizers. Violent reactions with alkali carbonates, oxidants, (Al + PbO), Ca, Cs₂C₂, Cl₂, CoF₂, F₂, IF₅, MnF₃, Rb₂C₂, FNO, AgF, NaK alloy. When heated it will react with water or steam to produce H₂; can react with oxidizing materials.
