Phosphine (PH3)

Phosphorus trihydride (PH3) – most commonly known as phosphine – is mainly used for fumigation applications because of 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 hydrocabons, aluminium or copper; and explosive – spontaneoulsy flammable in the air (R17).
