Danger

Chemical: Phosphine, triphenyl-

Phosphine, triphenyl- is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Phosphine, triphenyl- 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)

Status: Active Update: 14-04-2023 https://echa.europa.eu/registration-dossier/-/registered-dossier/13659

Triphenylphosphine: Does not have an individual approval but may be used under an appropriate group standard

This compound is combustible. (NTP, 1992)

Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Finely dispersed particles form explosive mixtures in air.

Decomposed by heating forming phosphine and phosphorous oxides; A skin, eye, and respiratory tract irritant; [ICSC] Causes convulsions at lethal doses in animal experiments; [RTECS] A strong reducing agent; [CAMEO] Harmful if ingested; May cause skin sensitization; [Aldrich MSDS] See Phosphine.

Fires involving this chemical can be controlled with dry chemical, carbon dioxide, or Halon extinguisher. (NTP, 1992)

Use water spray, foam, powder, carbon dioxide.

Fresh air, rest. Refer for medical attention.

Wear protective gloves when administering first aid. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .

Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer for medical attention.

Rinse mouth. Refer for medical attention .

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.

Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

Cough. Sore throat.

Redness.

Redness. Pain.

CNS EFFECTS: WEAKNESS & ATAXIA ONLY SYMPTOMS. IRRITANT EFFECTS: SLIGHT SKIN IRRITANT IN GUINEA PIG. /FROM TABLE/

DURING INHALATION EXPOSURE MALE CHR-CD RATS SHOWED MILD RESP IRRITATION; SEVERE WT LOSS OCCURRED IMMEDIATELY AFTER EXPOSURE, FOLLOWED BY NORMAL RATE OF WT GAIN. MILD WT LOSS OCCURRED DURING 10-DAY EXPOSURE PERIOD, FOLLOWED BY NORMAL WT GAIN.

Triphenylphosphine (TPP) was tested for mutagenicity in the Salmonella/microsome preincubation assay using a protocol approved by the National Toxicology Program. TPP was tested over a wide range of doses (0, 89, 285, 854, 2733 and 8200 ug/plate) in four Salmonella typhimurium strains (TA98, TA100, TA1535, and TA1537) in the presence and absence of Aroclor-induced rat or hamster liver S9. TPP was negative in these tests and the highest ineffective dose level tested (not causing formation of a precipitate) in any Salmonella tester strain was 89 ug/plate.

Used as a polymerization initiator and an intermediate to make pharmaceuticals, phosphonium salts, and other phosphorus compounds; [HSDB]
