Phosphorus trichloride can generate hydrochloric acid mist in the air. Has the effect of corrosion on the skin and mucous membrane irritation. Short term inhalation of vapor can cause upper respiratory tract irritation, throat inflammation, bronchitis, serious person can produce laryngeal edema induced by asphyxia, pneumonia or pulmonary edema. The skin and eye contact, can cause irritation or burns. Severe ocular burns can cause blindness. Chronic effects: long term exposure to low concentration can cause eye and respiratory tract irritation. Phosphorus can cause toxicity of oral disease.

The pharmaceutical industry for the production of sulfadiazine (S.D), sulfamethoxazole (S.M.D) five sulfamethoxydiazine. Dye industry for the condensation agent class of naphthol. Catalyst. Phosphorus solvent. Chlorinating agent. [1]
Safety measures
Sealed packaging, protected from light, keep dry. With alkali, oxidant and metal powder storage. Pay attention to personal protection, no direct physical contact. (eyes) skin contact, flush with water flow.
Risk overview editor
Pathways: inhalation, ingestion, skin absorption
Health hazards: phosphorus trichloride toxic gas irritant and corrosive. The water heated reaction, can cause explosion. The gas can be inhaled was conjunctiva inflammation, sore throat and eye tissue damage, have a stimulating effect on the lung and mucosa. The product of corrosion resistance, easy to burn and skin contact.
Environmental harm: harm to the environment, resulting in water contamination.
Explosive danger: flammable, toxic combustion produces nitrogen oxides and chlorides in water or alkali smoke; fever and explosion.
Emergency measures for editing
Skin contact: immediately remove contaminated clothing, immediately with a clean cloth or cotton to absorb liquid. Rinse with plenty of water flow. Medical treatment.
Eye contact: immediately filed eyelid, with plenty of liquid water or saline rinse thoroughly for at least 15 minutes. Medical treatment.
Inhalation: remove to fresh air. To maintain airway patency. If breathing is difficult, give oxygen. If breathing has stopped, artificial respiration immediately. Medical treatment.
Ingestion: rinse with water, no corrosion symptoms of gastric lavage. Not to use oil. Medical treatment.
Using the method of editing
Hazardous characteristics: water violent decomposition, produce a lot of heat and smoke, and even explosion. A lot of metal especially wet air in the presence of corrosive.
Hazardous combustion products: hydrogen chloride, phosphorus oxide, phosphine.
Fire extinguishing methods: fire personnel must wear systemic Naisuanjian fire clothing. Extinguishing agent: dry powder, carbon dioxide, dry sand. No water.
Emergency treatment
Emergency treatment: leakage of contaminated areas to evacuate personnel to a safe area, and immediately isolated 150m, restricted entry. Recommended emergency personnel wear self positive pressure respirator, wear anti acid overalls. Do not contact with the leakage. As far as possible to cut off the source of leakage. A small leak: absorb with sand, vermiculite or other inert materials. A large leak: construct a barrierpit to contain. Clear under the guidance of experts.
Handling and storage
Operation note: airtight operation, pay attention to ventilation. As far as possible the operation of mechanization and automation. The operator must go through specialized training, strictly abide by the rules. Recommended operating personnel wear self absorption filter mask (full cover), wearing protective chemical safety glasses, wear rubber acidproof alkali, wear rubber gloves acid. To prevent steam leakage in the air of workplace. Avoid contact with oxidizing agents, acids, alkalis. Pay particular attention to avoid contact with water. When moving to light light unloading, prevent damage to packaging and containers. Equipped with emergency treatment equipment. Empty containers may be harmful remains.
Storage note: store in a cool, dry and ventilated warehouse. Keep away from fire and heat source. Base temperature does not exceed 25 degrees, relative humidity of not more than 75%. The packing must be sealed, keep dry. Should be kept separate from oxidizing agents, acids, alkalis, edible chemicals, avoid mixing reservoir. Should not be stored for a long time, in order to avoid the deterioration. Storage areas should be equipped with emergency treatment equipment and proper acceptancematerials.
