Anwendungen & Verwendung

Beschreibung

Phosphorus trichloride, PCl3, is a clear, colorless, fuming, corrosive liquid. It decomposes rapidly in moist air and has a boiling point of about 168°F (75°C). PCl3 is corrosive to skin and tissue and reacts with water to form hydrochloric acid. The TLV is 0.2 ppm, and the IDLH is 50 ppm in air. The four-digit UN identification number is 1809. The NFPA 704 designation is health 4, flammability 0, and reactivity 2. The white section at the bottom of the diamond contains a W with a slash through it, indicating water reactivity. The primary uses are in the manufacture of organophosphate pesticides, gasoline additives, and dyestuffs; as a chlorinating agent; as a catalyst; and in textile finishing. Corrosives in contact with a poison may produce poison gases as the poison decomposes. In responding to an incident involving corrosives, the toxicity of the vapors could be much more of a concern for personnel than the corrosivity. When acids come in contact with cyanide, hydrogen cyanide gas, which is highly toxic, with a TLV of 10 ppm in air, is produced.

Verwenden

Phosphorus trichloride is an important intermediate in the production of insecticides, herbicides, and organophosphorus pesticides as well as other chemicals such as phosphoryl chloride, phosphorus pentachloride, thiophosphoryl chloride, and phosphonic acid. It is also used in the production of synthetic surfactants, phosphites, gasoline additives, flame retardants, silver polish, and producing iridescent metallic deposits.

Erste HilfeWarning: Phosphorus trichloride is a corrosive agent. Contact with eyes may result in severe damage to the cornea, conjunctiva, and blood vessels. Caution is advised.Signs and Symptoms of Phosphorus Trichloride Exposure: Acute exposure to phosphorus trichloride may result in irritation and burning of the skin, eyes, and mucous membranes. Light- headedness, drowsiness, slurred speech, pupillary dilation, increased salivation, dysphagia (difficulty swallowing), abdominal pain, and spontaneous vomiting may occur. Stridor (high-pitched, noisy respirations), dyspnea (shortness of breath), and pulmonary edema are also common. Apathy and mental confusion may develop, with progression to coma and death.Emergency Life-Support Procedures: Acute exposure to phosphorus trichloride may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination. Air-purifying or supplied-air respiratory equipment should also be worn, as necessary. Rescue vehicles should carry supplies such as plastic sheeting and disposable plastic bags to assist in preventing spread of contamination.Inhalation Exposure:1. Move victims to fresh air. Emergency personnel should avoid self-exposure to phosphorus trichloride.2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support.3. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.4. Transport to a health care facility.Dermal/Eye Exposure:1. Remove victims from exposure. Emergency personnel should avoid self-exposure to phosphorus trichloride.3. Remove contaminated clothing as soon as possible.4. If eye exposure has occurred, eyes must be flushed with lukewarm water for at least 30 minutes.5. Wash exposed skin areas thoroughly with water.6. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.7. Transport to a health care facility.Ingestion Exposure:1. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support.2. DO NOT induce vomiting or attempt to neutralize!General First Aid:· Call 911 or emergency medical service.· Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and avoid contamination.· Move victim to fresh air if it can be done safely.· Administer oxygen if breathing is difficult.· If victim is not breathing:-- DO NOT perform mouth-to-mouth resuscitationthe victim may have ingested or inhaled the substance.-- If equipped and pulse detected, wash face and mouth, then give artificial respiration using a proper respiratory medical device (bag-valve mask, pocket mask equipped with a one-way valve or other device).-- If no pulse detected or no respiratory medical device available, provide continuous compressions. Conduct a pulse check every two minutes or monitor for any signs of spontaneous respirations.· Remove and isolate contaminated clothing and shoes.· For minor skin contact, avoid spreading material on unaffected skin.· In case of contact with substance, remove immediately by flushing skin or eyes with running water for at least 20 minutes.· For severe burns, immediate medical attention is required.· Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed.· Keep victim calm and warm.· Keep victim under observation.· For further assistance, contact your local Poison Control Center.· Note: Basic Life Support (BLS) and Advanced Life Support (ALS) should be done by trained professionals.Specific First Aid:· For corrosives, in case of contact, immediately flush skin or eyes with running water for at least 30 minutes. Additional flushing may be required.(General first aid procedures)Eye: Irrigate immediately - If this chemical contacts the eyes, immediately wash (irrigate) the eyes with large amounts of water, occasionally lifting the lower and upper lids.

Human Toxicity Excerpts/SIGNS AND SYMPTOMS/ The signs of poisoning in 23 workers exposed to phosphorus trichloride at concentrations ranging from 1.8 to 27 ppm. Symptoms included burning eyes and throat, irritation of pharyngeal mucous membranes, and mild bronchitisthese changes occurred within 2 to 6 hours after exposure. Symptoms from subacute poisoning included irritation of the pharynx, coughing, dyspnea, and severe asthmatic bronchitis, which occurred 1 to 8 weeks after exposure. In workers who had at least 1 year exposure, emphysema was sometimes found. Both acute and subacute poisonings were frequently accompanied by fever and moderate leukocytosis and neutrophilia./SIGNS AND SYMPTOMS/ ... The corrosive effect /of phosphorus trichloride/ is complete destruction of skin or mucous membrane. /From table//SIGNS AND SYMPTOMS/ In a report of 17 persons exposed to phosphorus trichloride and its hydration products, those closest to the spill experienced burning eyes, lacrimation, nausea, vomiting, dyspnea, and cough. Pulmonary function tests showed decrements in vital capacity, maximal breathing capacity, and forced expiratory volume in direct correlation to the distance from the accident./SIGNS AND SYMPTOMS/ Phosphorus trichloride will cause severe burns upon direct dermal contact.For more Human Toxicity Excerpts (Complete) data for PHOSPHORUS TRICHLORIDE (13 total), please visit the HSDB record page.
