Carbon Monoxide Level in ppm (Parts per Million). Resulting Conditions / Effects on Humans. 50. Permissible Exposure Level (PEL) for 8 hours (OSHA). 200. 1 ppm = 1.16 mgm-3 for carbon monoxide at 293K (20 C) and 1013mb.

For those who want to do the conversion, 1ppm = 1.145 mg/m3 and 1mg/m3 = 0.873 ppm. For those who don’t, remember that any level in mg/m3 is about 10% less when expressed in ppm. Carbon monoxide (chemical formula CO) is a colorless, odorless, and tasteless flammable gas that is slightly less dense than air.It is toxic to animals that use hemoglobin as an oxygen carrier when encountered in concentrations above about 35 ppm causing carbon monoxide poisoning.

Exposure evaluation. Global background concentrations of carbon monoxide range between 0.06 mg/m 3 and 0.14 mg/m 3 (0.05-0.12 ppm). In urban traffic environments of large European cities, the 8-hour average carbon monoxide concentrations are generally lower than 20 mg/m 3 (17 ppm) with short-lasting peaks below 60 mg/m 3 (53 ppm). Carbon monoxide concentrations inside vehicles are generally

Normal Even low carbon monoxide levels over long periods can have an impact on brain chemistry. While exact short term and long term CO levels recommended by ASHRAE, OSHA, NIOSH and other organizations differ, the consensus is that 9 ppm (parts-per-million) is the maximum indoor safe carbon monoxide level over 8 hours. 27 ppm.

For those who don’t, remember that any level in mg/m3 is about 10% less when expressed in ppm. At what level does carbon monoxide become toxic? For healthy adults CO becomes toxic when it reaches a level higher than 35 ppm (parts per million) with continuous exposure over an eight hour period.. When the level of CO becomes higher than that a person will suffer from symptoms of exposure. Carbon Monoxide is a highly toxic gas that has no color or odor.
