Phosphorige Säure-trichlorid

Spray cooling water on containers that are exposed to flames until well after fire is out. Do not get water inside containers.

NO hydrous agents. NO water. In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water.

Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.

Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth. Do NOT induce vomiting. Refer for medical attention .

· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.

Warning: Phosphorus trichloride is a corrosive agent. Contact with eyes may result in severe damage to the cornea, conjunctiva, and blood vessels. Caution is advised.

General First Aid:

(General first aid procedures)

The vapor is heavier than air ... A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20 °C.

Severe health hazard. May be fatal if inhaled ... Corrosive ...

Reacts violently with fire extinguishing agents such as water ... Reacts violently with water producing heat and decomposition products including hydrochloric acid and phosphorous acid, causing fire and explosion hazard.

· Wear positive pressure self-contained breathing apparatus (SCBA).

TIH (Toxic Inhalation Hazard) - Term used to describe gases and volatile liquids that are toxic when inhaled. Some are TIH materials themselves, e.g., chlorine, and some release TIH gases when spilled in water, e.g., chlorosilanes. [ERG 2016].

0.1 [ppm]

Evacuation: If fire becomes uncontrollable or container is exposed to direct flame - consider evacuation of one-third (1/3) mile radius.

If material on fire or involved in fire: Use dry chemical, dry sand, or carbon dioxide. Do not use water on material itself. If large quantities of combustibles are involved, use water in flooding quantites of water. Apply water from as far a distance as possible.

... Use water spray to knock down acid vapors.

NO hydrous agents. NO water ...

Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs. See Chemical Dangers. Dry. Well closed. Ventilation along the floor.

Store in cool, dry, well-ventilated location. Separate from acids, alkalies, organics, alkali metals.

Environmental considerations: water spill: Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaCO3). Use mechanical dredges or lifts to remove immobilized masses of pollutant and precipitates. Adjust pH to neutral (pH=7).

Environmental considerations: air spill: Apply water spray or mist to knock down vapors. Vapor knockdown water is corrosive or toxic and should be diked for containment.

Environmental considerations: land spill: Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash or cement powder. Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3).

Releases may require isolation or evacuation. Use water spray to cool and disperse vapors and protect personnel.

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

Spillage should be handled only by an operator wearing full protective clothing and full-face mask/positive-pressure breathing apparatus. Absorbed spillage and residues should be buried in an approved landfill, away from water sources.

The substance can be absorbed into the body by inhalation and by ingestion.

/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 bronchitis; these 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.

/LABORATORY ANIMALS: Acute Exposure/ ... Working with cats & guinea pigs /investigators/ found that a concentration of 0.7 ppm produced only slight illness in 6 hr. 2 to 4 ppm did not produce severe symptoms in 1 hr, but serious disturbances resulted from 1 hr at 50 to 90 ppm. Effects of phosphorous trichloride were considered 5 to 10 times as intense as would result from hydrogen chloride produced by hydrolysis.[American Conference of Governmental Industrial Hygienists.
