Description

A colorless, poisonous gas that smells like rotting fish. Phosphine has been used as a Fumigant but its use is now restricted. Fumigation with phosphine gas can cause damage to metals, metals salts, and sulfur containing materials such as leather, fur, hair, and feathers.

Synonyms and Related Terms

hydrogen phosphide; phosphoretted hydrogen; phosphorus trihydride; phosphorus hydride; phosphene (sp); Phostoxin; Celphos; Delicia Gastoxin; Detio-Gas-Ex-T; Ex-B;

Risks

Highly flammable.
Highly toxic by inhalation. Lethal doses at part per million levels.
At elevated temperatures and humidities, phosphine will corrode copper, copper alloys, and silver. Reactions are accelerated in the presence of ammonia or salty air.
