When exposed to air, it spontaneously ignites and is oxidized rapidly to phosphorus pentoxide. Phosphorus 3.03 mg/kg (Rat) 4.3 mg/L (1 hr-Rat) 100 mg/kg (Rat) ACUTE TOXICITY: In summer white phosphorus burn on its own because its ignition temperature is 35% and can easily catch fire in the room temperature.-1 ; In summer, if white phosphorus is kept outside,it can react with oxygen easily and also that it has very low ignition temp. When red phosphorus burns, the evaporated phosphorus will condense as white phosphorus, which creates a fire (reignition) and health hazard. White phosphorus is self-igniting when it interacts with oxygen at a temperature of 86 degrees. "White phosphorus (P4) is the elemental form of phosphorus used in smoke munitions. Phosphorus will spontaneously ignite if exposed to air. Similarly, dermal application of the element to guinea pigs resulted in no skin irritation or sensitization. Summary about a hazardous substance taken from Chapter One of its respective ATSDR Toxicological Profile. White phosphorus (P), also known as yellow phosphorus, is a nonmetallic element that is found in the form of crystals or a wax-like transparent solid. Red phosphorus may be formed by heating white phosphorus to 300 °C (572 °F) in the absence of air or by exposing white phosphorus to sunlight. The form used by the military is highly energetic (active) and ignites once it is exposed to oxygen. Phosphorus exists in three forms in nature: (i) White phosphorus used as firecrackers, (ii) red phosphorus used in matches, and (iii) black phosphorus obtained by phase transformation of white phosphorus or red phosphorous at high temperature and pressure. Phosphorus occurs in at least 10 allotropic forms, the most common (and reactive) of which is so-called white (or yellow) phosphorus which looks like a … White phosphorus is an allotrope of phosphorus which exists as a translucent waxy solid.

WHITE phosphorus is a waxy, highly toxic substance which melts at 44.8° C, and ignites spontaneously at ordinary temperatures (1). For example; LPG, petrol, […] Although the reactions of red and white phosphorus are generally the same, most reactions are carried out using the red allotrope given that it is much safer to handle. 2012Āìe`¤ñŸÉò#@€ @Fc White phosphorus is used by the military in various types of ammunition, and to produce smoke for concealing troop movements and identifying targets. Such heat is produced by this reaction that the element bursts into a yellow flame and produces a dense white smoke. By means of degrees--Fahrenheit or Celsius--how hot can/does this WP get once it ignites? It is also used by industry to produce phosphoric acid and other chemicals for use in fertilizers, food additives, and cleaning compounds. The use of this material as an antipersonnel agent, in incendiary bombs, and as a smoke-producing chemical has intensified the military and industrial problems of control of phosphorus fires. It is smoke free fuel. WP, or white-phosphorus, when used as an incendiary weapon (i.e., such as a 40mm WP grenade), causes a blast ensued by 'sticky fire.' 55000 kJ/ kg. Red phosphorus was not considered a sensitizer when tested on the skin of guinea pigs. When the carbon disulfide evaporated, the phosphorus would burst into flames, and probably also ignite the highly flammable carbon disulfide fumes. 1.

WP is a colorless to yellow translucent wax-like substance with a pungent, garlic-like smell. However the ignition temperature is much higher (260 °C compared to 30 °C for white phosphorus). The MRL is an estimate of the daily human exposure to a hazardous substance that is likely to be without appreciable risk of adverse, non-cancer health effects over a specified duration of exposure. This compound exists as a translucent waxy solid that quickly becomes yellow when exposed to light. Phosphorus reacts violently with oxidants, halogens, some metals, nitrites, sulfur, and many other compounds, causing a fire hazard. If it burns in a little air, it produces poisonous phosphorus(III) oxide. endstream endobj startxref White phosphorus reacts rapidly with oxygen, easily catching fire at temperatures 10 to 15 degrees above room temperature.
