Phosphorochloridic acid, diethyl ester: Does not have an individual approval but may be used under an appropriate group standard
The New Jersey Worker and Community Right to Know Act requires public and private employers to provide information about hazardous substances at their workplaces. (N.J.S.A. 34:5A-1 et. seq.)
DOT LabelPoison
Fire HazardsEmits very toxic fumes of chloride and phosphorus oxides when heated to decomposition. (EPA, 1998)
Fire PotentialCombustible
Health HazardsThis material is a cholinesterase inhibitor. It has high oral and very high dermal toxicity. It is a skin irritant. It is also toxic by inhalation. (EPA, 1998)
Hazards Summary
A cholinesterase inhibitor; [Hawley] A cholinesterase inhibitor and skin irritant; Highly toxic by ingestion and skin absorption; [CAMEO] A mild skin irritant; Somnolence and convulsions observed in lethal-dose feeding studies of mice; [RTECS]
Reactive GroupEsters, Sulfate Esters, Phosphate Esters, Thiophosphate Esters, and Borate Esters
Reactivity Profile
Organophosphates, such as DIETHYL CHLOROPHOSPHATE, 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.
Air and Water ReactionsNo rapid reaction with air. No rapid reaction with water.
CERCLA Reportable Quantities
Releases of CERCLA hazardous substances are subject to the release reporting requirement of CERCLA section 103, codified at 40 CFR part 302, in addition to the requirements of 40 CFR part 355. Diethyl chlorophosphate is an extremely hazardous substance (EHS) subject to reporting requirements when stored in amounts in excess of its threshold planning quantity (TPQ) of 500 lbs.
Hazard Classes and CategoriesAcute Tox. 2 (100%)
Sicherheit und Schutzausrüstung
Fire Fighting
Use the following procedures for combustible liquids. Move container from fire area if you can do it without risk. Cool containers that are exposed to flames with water from the side until well after fire is out. For massive fire in cargo area, use unmanned hose holder or monitor nozzles; if this is impossible, withdraw from area and let fire burn. Withdraw immediately in case of rising sound from venting safety device or any discoloration of tank due to fire. Keep unnecessary people away; isolate hazard area and deny entry. Stay upwind; keep out of low areas. Wear self-contained (positive pressure if available) breathing apparatus and full protective clothing. Isolate for 1/2 mile in all directions if tank car or truck is involved in fire.
First AidNote: Diethyl chlorophosphate is a cholinesterase inhibitor.
Nonfire Spill ResponseCaution : Avoid sources of extreme heat including fire. Diethyl chlorophosphate will liberate toxic phosphorus oxide fumes and hydrogen chloride gas when heated to decomposition.
Disposal Methods
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.
