Red phosphorus is often contaminated with white and yellow phosphorus.
Therefore information of the two other allotropic forms included.
Red phosphorus is not absorbed very well.
Lethal dose in mammals 1.4 - 4.8 mg/kg bw (allotropic form not
specified). Pure red phosphorus is apparently less harmful than the
two other allotropic forms. Inhalation of 4.3 mg/l red phosphorus
(1h) or 1.5 mg/l (4 h) killed 9 respectively 2 of 10 rats.
The substance is classified as highly flammable and may explode
when exposed to heat or by chemical reaction with oxidisers. Red
phosphorus can also react with reducing materials and represent a
moderate explosion hazard by chemical reaction or on contact with
organic materials.
It reacts with oxygen and water vapour to produce the toxic
phosphine. The abiotic degradation of yellow phosphorus proceeds
at ambient temperature.

No ecotoxicological data on red phosphorus were located.
Yellow phosphorus is very toxic to crustaceans and fish in standard
tests (down to 0.011 mg/l and 0.018 mg/l, respectively)
