Uses
Hazard
The red allotrope of phosphorus is relatively harmless physiologically, unless it contains some of the white allotrope, which is very toxic. Irritant. Contact with eyes may cause irritation or burns. In contrast with the red allotrope, the white (yellow) allotrope of phosphorus is very toxic if swallowed or inhaled, and may cause severe burns.
Stability
Stable. Highly flammable. Incompatible with strong oxidizing agents, strong bases. Light and heat sensitive.
