Detection of Phosgene
Phosgene has gained notoriety, because it has been used as a battle gas in World War 1.
Today it is very important basic material, widely used in the chemical and pharmaceutical industry. Without materials based on phosgene – reactions, our lifestyle would be completely different. Just think of polycarbonates, for instance Macrolon. This plastic is used in CD`s, bumpers of cars, body material of cars and many mechanical parts such a switches or handles.
Or Polyurethane: it is used in glues, paints, foams (in dash boards, matrasses, any kind of upholstery).
The most common method manufacturing phosgene is catalytic synthesis of carbon monoxide and chlorine under high pressure and temperature.
The toxic impact of phosgene is by inhalation. It damages the blood – air barrier in the lungs. The insidious fact is, that phosgene does not produce immediate symptoms. This may lead to a very dangerous situation, because the exposed person does not notice the need for medical therapy. For this reason in phosgene plants not only the concentration, but also the absolute exposure must be detected. The use of dosimeter badges is an absolute must in phosgene plants. These give the doctor accurate information which intensity of therapy is necessary.
Compur Monitors is technology leader when it comes to phosgene detection. The MEDIC badges monitor the total exposure, while continuously operating instruments detect the concentration in plants or workplaces in real – time. Monitox, Statox 501, Statox 502, Statox 505 and above all Statox 560 with self – test are well – known in the market. The Tracer can detect phosgene even in the ppb range in order to locate leaks
Ultra – sensitive and specific: The leak detector for very toxic gases.
