Reactivity Alerts
- Explosive
- Strong Oxidizing Agent
Air & Water Reactions
No rapid reaction with air
No rapid reaction with water
Fire Hazard
Special Hazards of Combustion Products: Toxic chlorinated biphenyls are formed in fires.
Behavior in Fire: Solid may explode. Burns very rapidly when ignited. Smoke is unusually heavy when paste form is involved. (USCG, 1999)
Behavior in Fire: Solid may explode. Burns very rapidly when ignited. Smoke is unusually heavy when paste form is involved. (USCG, 1999)
Health Hazard
Irritates eyes and (on prolonged contact) skin. Ingestion causes irritation of mouth and stomach. (USCG, 1999)
Reactivity Profile
In pure crystalline form there is danger of explosion upon heating, shock, or friction. Peroxides are good oxidizing agents. Organic compounds can ignite on contact with concentrated peroxides. Strongly reduced material such as sulfides, nitrides, and hydrides may react explosively with peroxides. There are few chemical classes that do not at least produce heat when mixed with peroxides. Many produce explosions or generate gases (toxic and nontoxic). Generally, dilute solutions of peroxides (<70%) are safe, but the presence of a catalyst (often a transition metal such as cobalt, iron, manganese, nickel, or vanadium) as an impurity may even then cause rapid decomposition, a buildup of heat, and even an explosion.
