TOXIC DOSE The recommended workplace limit (ACGIH TLV-TWA) for carbon monoxide is 25 ppm as an 8-hour time-weighted average. The level considered immediately dangerous to life or health (IDLH) is 1,200 ppm (0.12%). However, the duration of exposure is very important. Whereas exposure to...
Carbon monoxide (CO) is widely known to be a toxic gas that interferes with oxygen transport by the red blood cells. However, this "toxin" is continuously generated in the body by a heme-degrading enzyme called heme oxygenase. Our findings revealed that CO plays a crucial role in keeping ...

A Springfield, Mass. hotel also had a carbon monoxide poisoning incident. Two floors, approximately 50 guests, were evacuated due to deadly levels of the toxic gas, which were as high as 3,000 ppm. The source of the carbon monoxide poisoning was a faulty boiler, which released dangerous lev...
toxic Carbon Monoxide - to discharge directly into the room where the heater is fitted. If used for extended periods, the levels of Carbon Monoxide can build up to dangerous levels if there is a lack of ventilation. Open flue-type water heaters located in bathrooms are also considered unsafe...
Mass carbon monoxide poisoning: Clinical effects and results of treatment in 184 victims An epidemiologic and clinical investigation of 184 persons exposed to toxic levels of carbon monoxide (CO) in a public high school has been carried out. Ex... Richard,E.,Burney,... - 《Annals of Emergenc...
Carbon monoxide (CO) may be the cause of more than one-half of the fatal poisonings reported in many countries; fatal cases also are grossly under-reported or misdiagnosed by medical professionals. Therefore, the precise number of individuals who have suffered from CO intoxication is not known...
INTRODUCTION: Carbon monoxide (CO) is a toxic gas with potential for detriment to spaceflight operations. An analytical model was developed to investigate if a maximum CO contamination of 1 ppm in the oxygen (O2) supply reached dangerous levels during extravehicular activity (EVA). Occupational mon...

Carbon monoxide is a colorless, odorless, nonirritating gas produced by the inefficient combustion of carbon fuels. It is potentially toxic for cats as well as humans.
