Ethyl phosphonothioic dichloride, anhydrous appears as a clear colorless liquid with a pungent odor. Burns, but may be difficult to ignite. Denser than water. Very toxic by inhalation. Corrosive to metals and tissue.

Clear liquid with a sulfur or phosphorus odor; [CHEMINFO MSDS]

Combustible. POISONOUS GASES ARE PRODUCED IN FIRE. Oxides of sulfur, phosphorus; hydrogen chloride and phosgene. Contact with water applied to adjacent fires will produce irritating fumes of hydrogen chloride. (USCG, 1999)

· Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.

GAS PRODUCED IN REACTION WITH WATER. POISONOUS IF INHALED. Irritating to eyes, nose and throat. LIQUID: Irritating to skin and eyes. Harmful if swallowed. (USCG, 1999)

· TOXIC and/or CORROSIVE; inhalation, ingestion or skin contact with material may cause severe injury or death.

In inhalation studies, animals survive 50 mg/m3 (7.5 ppm) for 1 hour or 5 mg/m3 (0.75 ppm) for 4 hours. At 500 mg/m3 (75 ppm) death occurs in less than 1 hour following labored respiration and lung hemorrhage. Corrosive to skin, eyes, and respiratory tract; [CHEMINFO MSDS] Reacts with water to release hydrogen chloride; [CAMEO]

An acid halide and organothiophosphate. Acid halides are water reactive; some are violently reactive. They are incompatible with strong oxidizing agents, alcohols, amines, alkali. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291]. Organothiophosphates are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.

Div 6.1 Poisonous materials (49 eCFR § 173.132)

PG I: the degree of danger presented by the material is great

Symbol D: The proper shipping name which is appropriate for describing material for domestic transportation

· 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.

· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.

INHALATION: remove victim from exposure; oxygen can be used for pulmonary symptoms with decongestants; enforce complete rest, because effects may be delayed 24 hours; similar to phosgene poisoning.

General First Aid:

· 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].
