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 gas detector, monitoring equipment and PH3 respiratory protection

Phosphine 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).

PH3 phosphine gas effects on health

Phosphine gas detector - PH3

Despite its fishy smell, only a phosphine gas detector can accurately measure concentrations of this gas. Moreover, although PH3 can explode at 1.6% volume, an explosivity monitoring is pointless as this gas is very toxic. Thus it is advised to use ppm or ppb phosphine gas detection equipment to preserve safety.

Additional information

The GASBADGE PRO toxic gas detector is a classic single-gas detector. Its long-duration battery operates for about 2,600 hours and can be replaced when used. As for any other classic single-gas detectors, it is highly recommended to calibrate the GASBADGE PRO twice a year to ensure proper operation.

The GASBADGE PRO toxic gas monitor is a classic single-gas detector with interchangeable sensors and features a large range of electrochemical sensors. This technology is designed to detect toxic gases: Cl2 (chlorine), ClO2 (chlorine dioxide), CO (carbon monoxide), HCN (hydrogen cyanide), H2 (hydrogen), H2S (hydrogen sulfide), NH3 (ammonia), NO2 (nitrogen dioxide), O2 (oxygen), PH3 (phosphine) and SO2 (sulfur dioxide).

The GASBADGE PRO has 3 alarms: a powerful 95 dB audible alarm to alert even in noisy environments, a red LED visual alarm for view alert signals even in the darkest places like confined spaces and a vibrating alarm.

These alarms will be triggered by 4 events: if the lower or the upper limit values are reached, if concentrations get over the occupational exposure limit or if the average value threshold is exceeded. Abnormal gas concentrations and other data can also be saved and downloaded from the device.

Compact and lightweight, the GASBADGE PRO toxic gas detector is made with a strong polycarbonate housing with a robust and waterproof over-mold in compliance with IP67 protection. The GASBADGE PRO is ATEX approved as well for explosive atmosphere under current EU standards.
