Carbon monoxide (CO). A colorless, odorless gas, produced by the incomplete combustion of carbonaceous material, having an effect which is predominantly one causing asphyxia.
Protection from adverse health effects caused by the affinity of hemoglobin for carbon monoxide which is over 200 times greater than that for oxygen, resulting in a decrease of oxygen circulation through the body.
(a) For all levels. For an eight-hour period, the average concentration of carbon monoxide shall not exceed nine ppm1 more than once in any 12 consecutive months.
(b) For all levels. For a one-hour period, the average concentration of carbon monoxide shall not exceed 35 ppm2 more than once in any 12 consecutive months.
- 1Corresponds to Federal standard of 10 mg/m3 (at temperature of 25oC and pressure of 760 mm of mercury).
- 2Corresponds to Federal standard of 40 mg/m3 (at temperature of 25oC and pressure of 760 mm of mercury).
(a) Carbon monoxide (CO) is determined continuously by the nondispersive infrared spectrometry.
(b) All measurements are corrected to a reference temperature of 25 degrees Centigrade and to a reference pressure of 760 millimeters of mercury.
