Phosphine - PH3

Find here the essential information on phosphine - or phosphorus trihydride - (PH3): characteristics, effects on health, detection devices & systems - Phosphine gas detector - and proper respiratory protective equipment (gas mask or PAPR with B gas filter).

Phosphine (PH3) properties

Phosphorus trihydride (PH3) - most commonly known as phosphine - is mainly used for fumigation applications because of its biocide properties – required for international transport. Phosphine is also industrially released while producing acetylene, during metals de-rusting process with phosphoric acid or in metal treatment plants with phosphides.

Phosphine gas effects on health

Phosphine is a colorless gas that can be detected through its fishy smell. This gas is very toxic by inhalation (R26) and can cause chemical burns (R34). This substance is very harmful for the environment, especially for aquatic organisms (R50). It is extremely flammable (R12) when in contact with oxidizers, halogenated hydrocarbons, aluminum or copper; and explosive - spontaneously flammable in the air (R17).
