Phosgene – COCl2

Find here the essential information on phosgene (COCl2) or carbon dichloride oxide: characteristics, effects on health, appropriate detection means – phosgene gas detector – and respiratory protective equipment (gas mask or powered air purifying respirator with B-P3 combined filter).

Phosgene gas detector sensor and COCl2 respiratory protection

Phosgene properties

Carbon dichloride oxide (COCl2) – most commonly known as phosgene – is synthetized through reaction between carbon monoxide and chlorine. It can also be released during chlorinated hydrocarbon vapor decomposition or plastics pyrolysis. It can be found in the chemical industry – herbicide and insecticide synthesis – and during production of pharmaceutical products, dye and chlorination agents.

Phosgene effects on health

As phosgene (COCl2) is extremely toxic, it has been used as a chemical weapon and a poison gas during the First World War. This gas is very toxic by inhalation (R26) and causes chemical burns (R34). At ambient temperature, this gas is colorless or sometimes slightly yellowish with a decomposition smell – moldy hay or rotten apple.

Phosgene gas effects, exposure poisoning symptoms: why use a COCl2 detector

Phosgene gas effects on health (COCl2)

Phosgene gas detector - COCl2

Even if phosgene is detectable through smell, only a phosgene gas detector can accurately measure concentrations of this highly toxic gas. It is recommended to use a phosgene detection system in ppm or ppb.

The colorimetric gas detection tube system is a simple and accurate solution composed by a manual sampling pump and a specific gas detection tube. They are designed for use together.

  • Gas detector tubes Colorimetric tube
  • Accurate: the sampling pump features a mechanical accuracy piston which creates a vacuum then enables direct reading on the colored tube (colorimetric tube)
  • Swift: one or two pump strokes are enough to draw sample and the value can be directly read on the tube
  • User-friendly: no knowledge, no specific process and no technical competence are required

PortaSense II gas leak detector is a single-gas detector to monitor rare gases. This device is powered with a D alkaline battery for around 75 hours runtime and an internal Nicad battery with an autonomy of around 6 hours.

The PortaSense gas leak detector can detect many gases thanks to its large range of interchangeable sensors. Majors detected gases are: alcohol, B2H6, Br2, C2H2, CH2O, Cl2, ClO2, CO, COCl2, F2, acid gas, GeH4, H2, H2O2, H2S, HCl, HF, NH3, NO, NO2, O2, O3, PH3, SiH4. In complement to this detected gases, this monitor features different measuring ranges for every gas.

The PortaSense II primarily detect gas leaks with its integrated sampling pump. This enables accurate measurements of hazardous gas concentrations. This gas leak detector with interchangeable sensors is moreover calibration-free, which makes it very versatile.

This single-gas detector features audible and audible alarms with 3 levels: caution, warning, and alarm with adjustable setpoints. A fourth alarm will indicate a low flow or low battery.

Thanks to its internal memory, the detector can record event data during 8 days with 1 minute interval. Furthermore, Portasense II features an RS32 output to connect a PC for data downloading.

As its name implies, the BM25 area gas monitor is designed to monitor a specific zone were people are working. In its 4 gas version, the BM25 features an autonomy of around 100 hours and is fully charged within 4 hours.

According to the most specific needs, many configurations are available. The BM25 area gas monitor indeed features a large range of sensors to detect up to 5 gases like arsine (AsH3), carbon dioxide (CO2), phosgene (COCl2), the combustible gases, hydrogene (H2), hydrogene cyanide (HCN), hydrogene chloride (HCl), hydrogene fluoride (HF), hydrogen sulfide (H2S), nitric oxide (NO), nitrogen dioxide (NO2), oxygene (O2), phosphine (PH3), sulfur dioxide (SO2) and the volatile organic compounds (VOC).

In order to alert every worker evolving in the monitored area of any gas hazard, the BM25 area gas monitor features a two-way 103 dB audible alarm at one meter. A high visibility red light is added to the safety unit to evolve safely in noisy and/or dark areas.
