Phosphorodichloridic acid, ethyl ester is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Phosphorodichloridic acid, ethyl ester are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)

Special Hazards of Combustion Products: Irritating fumes of hydrogen chloride and phosphoric acid may be formed.

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

Inhalation of vapor irritates nose and throat. Contact with liquid causes severe burns of eyes and skin. Ingestion causes severe burns of mouth and stomach. (USCG, 1999)

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

Caustic to skin and eyes by contact and to mouth and GI tract by ingestion; [CAMEO] Corrosive; Very toxic by inhalation--may cause chemical pneumonitis; Contact with water releases acidic gas, which on contact with metal, can produce explosive hydrogen gas; [MSDSonline]

Section 8(a) of TSCA requires manufacturers of this chemical substance to report preliminary assessment information concerned with production, use, and exposure to EPA as cited in the preamble in 51 FR 41329.

Pursuant to section 8(d) of TSCA, EPA promulgated a model Health and Safety Data Reporting Rule. The section 8(d) model rule requires manufacturers, importers, and processors of listed chemical substances and mixtures to submit to EPA copies and lists of unpublished health and safety studies. Phosphorodichloridic acid, ethyl ester is included on this list.

Organophosphates, such as ETHYL PHOSPHORODICHLORIDATE, 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; if his breathing has stopped, start artificial respiration, call a doctor.

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].

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
