PYROPHORIC NONMETALLIC SOLIDS
PYROPHORIC NONMETALLIC SOLIDS
Phosphorus
There are two different compounds of phosphorus (P4). These are commonly known as
white (or yellow) phosphorus, and red phosphorous. Red phosphorus is not considered
pyrophoric. However, red phosphorus ignites easily and produces phosphine (a pyrophoric
gas) during combustion.
Pyrophoric (white, or yellow) phosphorus is a colorless to yellow, translucent, nonmetallic
solid. It ignites spontaneously on contact with air at or above 30 C (86 F). Phosphorous is
explosive when mixed with oxidizing agents. Fumes from burning phosphorus are highly
irritating but only slightly toxic except in very high concentrations. Like red phosphorus,
white phosphorus also produces phosphine during combustion.
When storing, protect containers against physical damage. Phosphorus should always be
kept underwater, or under an inert atmosphere, separated from oxidizing agents and
combustible materials. When shipping, keep phosphorus under water in hermetically sealed
cans inside wooden boxes, under water in drums, or in tank motor vehicles or tank cars
under water or blanketed with an inert gas.
Phosphorous fires should be deluged with water until the fire is extinguished and the
phosphorus has solidified. The solidified phosphorus should then be covered with wet sand,
clay, or ground limestone.
