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.
