The revised IDLH for carbon monoxide is 1,200 ppm based on acute inhalation toxicity data in humans

Until this occurs, this list contains IDLH values based on both the 1994 revised criteria and CIB 66 [NIOSH 2014-100]. It is important to note which criteria was applied to develop a specific IDLH value.

Jan 11, 2024 · Carbon monoxide (CO) exposure is determined by calculation based on carboxyhemoglobin (COHb) measurements provided by medical professionals as described below. OSHA uses a modified Coburn, Forster, Kane (CFK) Calculation.

Emergency or planned entry into unknown concentrations or IDLH conditions: (APF = 10,000) Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode

IDLH: 1200 ppm (1374 mg/m3) Procedure: Expose a personal gas monitor using a carbon monoxide (CO) electrochemical sensor to workplace air. Recommended sampling time: Full shift (up to approximately 8 hours with new batteries) Reporting limit: 2 …

The Immediately dangerous to life or health air concentration values (IDLH values) developed by the National Institute for Occupational Safety and Health (NIOSH) characterize these high-risk exposure concentrations and conditions and are used as a component of respirator selection criteria first developed in the mid-1970s.

Basis for revised IDLH: The revised IDLH for carbon monoxide is 1,200 ppm based on acute inhalation toxicity data in humans [Henderson et al. 1921a, 1921b; NIOSH 1972; Stewart and Peterson 1970]. REFERENCES:
