(Shep-pard-1999) Significant risk of low birth weight if exposed during last trimester OSHA’s former limit for carbon monoxide was 50 ppm as an 8-hour TWA. The ACGIH has a TLV-TWA of 50 ppm with a TLV-STEL of 400 ppm. NIOSH (1973d/Ex. 1-237) recommends an 8-hour TWA limit of 35 ppm with a 200-ppm ceiling. 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.
