In eight households, carbon monoxide (CO) was measured using passive The average CO concentration during cooking was 4.3 ppm, with a maximum of

This PPM to mg/m3 conversion is based on the molecular weight of the chemical and it is different for every chemical. Carbon monoxide [CO] M = 28.01 g/mol: Carbon

The U.S. Consumer Product Safety Commission (CPSC) recommends that indoor exposure be limited to15 ppm averaged over 8 hours and 25 ppm for 1 hour. What can be done to reduce carbon monoxide hazards? Maximum of 35 ppm of CO for 1-hour exposure (not be exceeded more than once per year). Maximum of 9 ppm of CO for 8-hour exposure (not to be exceeded more than once per year). What is carbon monoxide? Carbon monoxide (CO) is a colorless, odorless deadly gas. Because you can't see, taste, or smell it, carbon monoxide can kill you before you Carbon Monoxide 2/a 2-300 ppm 67 33 051 Carbon Monoxide 5/c 5-700 ppm CH 25 601 Carbon Monoxide 8/a 8-150 ppm CH 19 701 (only for CO in H 2) Carbon Monoxide 10/b 10-3,000 ppm CH 20 601 Carbon Monoxide 10/d 10-3,000 ppm 81 03 321 Carbon Monoxide 0.3%/b 0.3-7 Vol.% CH 29 901 Carbon Pretubes CH 24 101 Carbon Tetrachloride 0.1/a 0.1-5 ppm 81 03 501 reported carbon monoxide peak concentrations of up to 60 mg/m3 (53 ppm) in homes with stoves operating on town gas.

However, a very common and immediate method of biochemically verifying 24-hr abstinence in clinical research is an expired-air carbon monoxide reading equal to or less than 8 ppm (CO < 8 ppm), or perhaps 10 ppm (Bailey, Bryson, & Killen, 2011; SRNT, 2002). CO’s typical 4-hr half-life makes it more sensitive for verifying 24-hr abstinence.

Data from Japan and the USA show that 8-h mean concentrations of carbon monoxide are generally less than 20 mg/m 3 (17 ppm). However, maximum 8-h mean concentrations of up to 60 mg/m 3 (53 ppm) have occasionally been recorded.

Carbon Monoxide Concentration Inhalation Time Toxic Symptoms 9 ppm Short term ASHRAE recommended maximum in a living area 35 ppm 8 hours OSHA maximum in a workplace in an 8 … Carbon Monoxide Detection Tubes 8/a (8 - 150 ppm) For short term measurements more than 160 Draeger Tubes are available to measure the so called spot concentrations of specific gases. A wide range of different gases and vapours can be detected and measured, such as: Determining and measuring concentration peaks A concentration of 400 ppm of CO is enough to produce unconsciousness and death over just a couple hours of exposure. Because carbon monoxide has no taste no color, and no smell, most people who are exposed don’t even know it. For this reason, it is known as … 2012-09-18 8-hour time-weighted average) is 50 ppm.

OSHA standards prohibit worker exposure to more than 50 parts of CO gas per million parts of air averaged during an 8-hour time period. • The 8-hour PEL for CO in maritime operations is also 50 ppm. Maritime workers, however, must be removed from exposure if the CO Carbon Monoxide Levels & Risks CO Level Action CO Level Action 1-4ppm 3-7ppm 5-6ppm 5ppm 9ppm 10ppm 15-20ppm 25ppm 27ppm 30ppm 35ppm Normal levels in human tissues produced by body.

av H Stockman-Juvala · 2012 — CO is also a constituent of tobacco smoke. Exposure to CO is common in many occupational areas, including those associated with vehicle exhaust.
