3CARBON MONOXIDE IS THE MOST COMMON TOXIC GAS CO is one of the few toxic gases that can be encounteredat home or on the jobAs a product of combustion, it is ubiquitousColorless and odorless, CO is a silent killer
4CO HEALTH EFFECTSAt ppm, can cause fatigue in healthy individuals, and chest pain in those with heart disease.At higher concentrations, can cause impaired vision and coordination; headaches; dizziness; confusion; nausea.Can cause flu-like symptoms (ca. 250 ppm) that clear upwhen in clean air.At 2000 ppm, can be rapidly fatal
5TOXICOLOGY Carbon monoxide is an asphyxiant Inhalation of CO causes tissue hypoxia by preventing the blood from carrying sufficient oxygenCarbon monoxide combines reversibly with hemoglobin to form carboxyhemoglobinThe reduction in oxygen-carrying capacity of the blood is proportional to the amount of carboxyhemoglobin formed
7OSHA Standards (as of Feb, 2011) The OSHA PEL ( Permissible Exposure Limit, based on an8-hour time-weighted average) is 50 ppmSpecial provision for maritime workers/longshoring[29 CFR (a)(1)(i))]…employees shall be removed from the enclosed space if the CO concentration exceeds a ceiling of 100 ppm.Exception: The ceiling shall be 200 ppm instead of 100 ppm for Ro-Ro operations.
8ACGIH TLV® [Threshold Limit Value] (as of Feb, 2011)TLV-TWA (based on an 8-hour time-weighted average)is 25 ppmBiological Exposure Index (BEI®) is recommended for carbon monoxide ─Based on percent carboxyhemoglobin saturation in blood, or end-expired CO concentration in alveolar air
9NIOSH REL [Recommended Exposure Limits] (as of Feb, 2011)TLV-TWA (based on an 8-hour time-weighted average)is 35 ppmCeiling value of 200 ppm(should not be exceeded at any time)
10NIOSH IDLH [Immediately Dangerous to Life and Health] (as of Feb, 2011)1200 ppmIDLH: The airborne concentration from which a worker could escape without injury or irreversible health effects, in the event of the failure of respiratory protection equipment.IDLH values are based on effects that might occur as a consequence of a 30-minute exposure.Regardless of the 30-minute basis, if equipment failure occurs,LEAVE THE AREA AT ONCE!!
