White phosphorus Chemical Properties,Uses,Production

Chemical Properties

Phosphorus is a white to yellow, soft, waxy solid with acrid fumes in air. White/yellow phosphorus is either a yellow or colorless, volatile, crystalline solid which darkens when exposed to light and ignites in air to form white fumes and greenish light. It has a garlic-like odor. Usually shipped or stored in water.

Potential Exposure

White or yellow phosphorus is handled away from air so that exposure is usually limited. Phosphorus was at one time used for the production of matches or “lucifers” but has long since been replaced due to its chronic toxicity. It is used in the manufacture of munitions including tracer bullets, pyrotechnics, explosives, smoke bombs; and other incendiary agents; (because it spontaneously catches fire in air) and as a smoke agent (because it produces clouds of irritating white smoke). Phosphorus is used artificial fertilizers; rodenticides, phosphor bronze alloys; semiconductors, Electro-luminescent coating; and chemicals, such as phosphoric and metallic phosphides. RP is used as a choking/pulmonary agent

First aid

There is no antidote for white phosphorus toxicity. If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 30 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and brush all traces of dry chemical from skin. Submerge burning phosphorus (yellow) in water or 1% copper sulfate solution if embedded in skin, or wash exposed area with large amounts of water. Seek medical attention immediately. Skin burns from yellow phosphorus should be observed for 13 days for possible delayed effects. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 2448 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

Incompatibilities

Phosphorus, a pyrophoric solid, spontaneously ignite on contact with air, producing toxic phosphorus oxide fumes. Reacts with strong bases, releasing toxic phosphine gas. Phosphorus reacts violently with oxidizers, halogens, some metals, nitrites, sulfur, and many other compounds, causing a fire and explosion hazard. White/yellow reacts with air, halogens, halides, sulfur, oxidizers, alkali hydroxides (forming gas); and metals (forming reactive phosphides). Red is a combustible solid. Friction or contact with oxidizers can cause ignition. Incompatible with many other substances. Forms gas and phosphoric acid on contact with moisture. Opened packages of red phosphorus should be stored under inert gas blanket.

Waste Disposal

Controlled incineration followed by alkaline scrubbing and particulate removal equipment.
