Phosphine decomposes on heating or on burning, producing toxic fumes. Phosphine reacts with acids, air, copper, moisture, and oxidants.

Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula P H 3, classed as a pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and diphosphane ( P 2 H 4 ).

Phosphine is extremely flammable and explosive; it may ignite spontaneously on contact, with air. Phosphine has a fish- or garlic-like odor, but may not provide adequate warning of hazardous concentrations. When phosphine burns it produces a dense white cloud of …

Phosphine (PH₃) is a colorless, flammable, and explosive gas at room temperature that smells like garlic or decaying fish. Exposure to phosphine may cause, nausea, vomiting, stomach pain, diarrhea, thirst, muscle pain, difficulty breathing, and fluid in the lungs

Phosphine is an extremely flammable, colourless, gas with an odour of garlic/rotten fish. Decontamination may not be necessary following exposure to phosphine as it exists as a gas at room...

Phosphine is a super- toxic gas with a probable oral lethal dose of 5 mg/kg or 7 drops for a 150 pound person. An air concentration of 3 ppm is safe for long term exposure, 500 ppm is lethal in 30 minutes, and a concentration of 1,000 ppm is lethal after a few breaths.

Gives off irritating or toxic fumes (or gases) in a fire. Gas/air mixtures are explosive. NO open flames, NO sparks and NO smoking. NO contact with hot surfaces. Closed system, ventilation, explosion-proof electrical equipment and lighting. Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out.
