WebPyrophoric Chemicals. Pyrophoric chemicals are used in research to catalyze certain reactions and often are incorporated into final products. However, they pose significant physical hazards. They are liquids and solids that will ignite spontaneously in the presence of oxygen and water. They must have limited to no exposure to the atmosphere. WebHAZARD. IDENTIFICATION Phosphine is a colorless gas with a fish-like odor. It is used as a fumigant, as a doping agent for electronic components, and in chemical synthesis. REASON FOR CITATION * Phosphine is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DOT, NIOSH, DEP, IRIS, NFPA and EPA.

The nine hazard classes are as follows: Class 1: Explosives. Class 2: Gases. Class 3: Flammable and Combustible Liquids. Class 4: Flammable Solids. Class 5: Oxidizing Substances, Organic Peroxides. WebPhosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula PH3, classed as a pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the … WebHealth Hazard Acute toxicity occurs primarily by the inhalation route when aluminum phosphide decomposes into the toxic gas, phosphine. The human median lethal dose for aluminum phosphide has been reported to be 20 mg/kg. Rated as super toxic: probable oral lethal dose is less than 5 mg/kg or less than 7 drops for a 70 kg (150 lb.) person. share chat unilever
