Aggregated GHS information provided per 257 reports by companies from 7 notifications to the ECHA C&L Inventory. Each notification may be associated with multiple companies.

Chemical: Phosphonic acid, ethyl-, diethyl ester

Status: Active Update: 29-07-2020 https://echa.europa.eu/registration-dossier/-/registered-dossier/26623

Phosphonic acid, ethyl-, diethyl ester: Does not have an individual approval but may be used under an appropriate group standard

COMBUSTIBLE

FIRE HAZARD: MODERATE, WHEN EXPOSED TO HEAT OR FLAME.

Organophosphates, such as DIETHYL ETHYLPHOSPHONATE, 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.

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

IN GENERAL, MATERIALS WHICH ARE TOXIC AS STORED OR WHICH CAN DECOMP INTO TOXIC COMPONENTS...SHOULD BE STORED IN A COOL, WELL-VENTILATED PLACE, OUT OF DIRECT RAYS OF THE SUN, AWAY FROM AREAS OF HIGH FIRE HAZARD, & SHOULD BE PERIODICALLY INSPECTED... INCOMPATIBLE MATERIALS SHOULD BE ISOLATED FROM EACH OTHER.

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

Diethyl ethylphosphonate (DEP) was tested for mutagenicity using the Salmonella/microsome preincubation assay using the standard protocol approved by the National Toxicology Program. DEP was tested at doses of 0.33, 1.0, 3.3, 10, and 10.2 mg/plate in as many as 5 Salmonella typhimurium strains (TA1535, TA1537, TA97, TA98, and TA100) in the presence and absence of rat or hamster liver S-9. DEP was negative in these tests and the highest ineffective dose tested in any S. typhimurium strain was 10.2 mg/plate.
