AppearanceWhite, hexagonal crystals. Odorless.
storage tempKeep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
Hazard Moderate fire risk, may explode if ground with chlorates, nitrates, or other strong oxidizing agents.
Safety
When heated it evolves phosphine which then ignites in air. Explodes on evaporation with HNO3. When heated to decomposition it emits very toxic fumes of POx and K2O.
