WB5950000 | [Safety Profile]
Poison by subcutaneous route. Moderately toxic by intraperitoneal route. Flammable when exposed to heat or flame. Aqueous solutions may explode on evaporation. Potentially explosive reaction with oxidants (e.g., chlorates, nitrates). Heat causes it to evolve phosphne. It can explode. When heated to decomposition it emits toxic fumes of POx and Na2O.

| Hazard Information | Back Directory | [Hazard]
Explosion risk when mixed with strong oxi-
dizing agents, decomposes to phosphine on heating,
store in cool, dry place, away from oxidizing mate-
rials.
