Phosphine – PH3

Phosphine here  – or phosphorus trihydride – ( PH3 ) you can find basic information about: properties, health effects, detection devices and systems – Phosphine gas detector  – and suitable respiratory protective equipment (gas mask or B with gas filter PAPR ).

Phosphine (PH3) properties

phosphorus trihydride ( PH3 ) – most commonly known as phosphine – used mainly for fumigation applications due to its biocidal properties required for international transportation. Phosphine also while producing acetylene , metals with phosphoric acid rust removal It is also released industrially during metal processing or in metal processing plants with phosphides.

Health effects of phosphine gas

Phosphine, with the smell of fish detectable colorless is a gas. this gas It is very toxic when inhaled (R26) and may cause chemical burns (R34). This article very harmful to the environment, especially to aquatic organisms (R50). Highly flammable when in contact with oxidants, halogenated hydrocarbons, aluminum or copper (R12); And is explosive – spontaneously flammable in air (R17).

Phosphine gas detector – PH3

Despite the fishy smell, there is only one phosphine gas detector can accurately measure concentrations of this gas. Furthermore, although PH3 can explode at 1.6% volume, explosiveness monitoring is pointless because this gas is so toxic. So to protect security ppm or ppb phosphine gas detection It is recommended to use equipment.

PH3 respiratory protection – Phosphine gas

To obtain appropriate protection against phosphine, full face mask a phosphine gas respirator (for short interventions only) or With type B gas filter equipped with a more comfortable powered air purifying respirator It is recommended to install . If concentrations exceed 60 times the OEL, a self-contained breathing apparatus (SCBA or powered air respirator) is required.
