§257-4.1 Definition
Carbon monoxide (CO). A colorless, odorless gas, produced by the incomplete combustion of carbonaceous material, having an effect which is predominantly one causing asphyxia.
§257-4.2 Objective
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.
§257-4.3 Standard
(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.

- 2Corresponds to Federal standard of 40 mg/m3 (at temperature of 25oC and pressure of 760 mm of mercury).
§257-4.4 Measurement
(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.
