Carbon Monoxide Gas Detectors (CO Detectors)

CO - Carbon Monoxide - steel mills, fire departments, garages, loading docks, electrical utilities, and general industriesCarbon monoxide (CO) is used by the chemical industry in the production of inorganic chemicals, as a reducing agent in metals refining, in food packaging, steel mills, loading docks, and electrical utilities. Particularly in danger of carbon monoxide exposure, are workers near or within confined spaces where CO is a byproduct of combustions. These areas include manholes, splicing vehicles, garages, tunnels, loading docks, warehouses, and vehicle repair shops. Industrial Scientific provides single-gas carbon monoxide detectors including the GasBadge® Pro and Tango® TX1, multi-gas detectors including the Ventis® Pro with LENS™ Wireless, and the Radius® BZ1 Area Monitor.

Carbon monoxide is a colorless gas. To the human senses, it is invisible. Carbon monoxide is a byproduct of combustion and will appear naturally in any situation where burning has taken place.

Carbon monoxide is a highly toxic gas which is termed a toxic asphyxiant, meaning it reduces the oxygen transport properties of the blood. It reacts with the hemoglobin in the blood-forming carboxyhemoglobin which prevents the hemoglobin from transferring oxygen. Low PPM doses of carbon monoxide can cause headaches and dizziness. If the victim is removed to fresh air no permanent damages will result. High doses can be fatal.
