SECTION 10: Stability and reactivity

Reactivity

Decomposes above 100°C . This produces toxic and flammable products including selenium (ICSC 0072) and hydrogen (ICSC 0001). The substance is a strong reducing agent. It reacts violently with oxidants. This generates fire and explosion hazard. Contact with air generates toxic and corrosive fumes of selenium dioxide (see ICSC 0946).

Chemical stability

no data available

Possibility of hazardous reactions

The gas is heavier than air and may travel along the ground; distant ignition possible.

Conditions to avoid

no data available

Incompatible materials

CHEMICAL PROFILE: A colorless, flammable gas of unpleasant odor, a deadly poison by inhalation. It forms explosive mixtures with air. It reacts vigorously with strong oxidizing reagents, e.g., hydrogen peroxide, nitric acid [Sax, 9th ed., 1996, p.1843]. (REACTIVITY, 1999)
