Carbon monoxide is a colorless, odorless gas. Prolonged exposure to carbon monoxide rich atmospheres may be fatal. It is easily ignited. It is just lighter than air and a flame can flash back to the source of leak very easily. Under prolonged exposure to fire or intense …

8 ppm carbon monoxide

8 The Smokerlyser measures breath CO levels in parts per million. (ppm) based on the conversion of CO to carbon dioxide (CO2) over a catalytically active Carbon monoxide (CO) is an odorless and colorless gas which 50 ppm. Maximum level for continuous exposure in an 8 hour workday. Health alert for E.g.: If the measured CO is 50 ppm and the measured oxygen in the flue gas is 10.5%.

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.

In most fuel burning appliances, the combustion process is not quite perfect, and instead of oxygen and carbon combining perfectly, a single carbon atom will combine with one oxygen atom and CO will be the result. Therefore the 8-hour working limit of 20 ppm (23 mg/m 3) and the short term 15 minute value of 100 ppm (117 mg/m 3) are selected as the DNELs for occupational exposure. These values equate to COHb levels of approximately 3% and following a review of the latest available data there are no new studies which would negatively impact upon the position that these values are protective with regard to Carbon monoxide (CO) is usually recognized as a toxic gas that can be used to assess lung function in the pulmonary function laboratory. The toxicity of CO relates to its high affinity for hemoglobin and other heme molecules, producing carboxyhemoglobin (HbCO).

(Shep-pard-1999) Significant risk of low birth weight if exposed during last trimester

What can be done to reduce carbon monoxide hazards? reported carbon monoxide peak concentrations of up to 60 mg/m3 (53 ppm) in homes with stoves operating on town gas.

All CO levels below are stated in parts per million (ppm) unless otherwise noted. World Health Organization (WHO) standards are published in mg/m3. For those who want to do the conversion, 1ppm = 1.145 mg/m3 and 1mg/m3 = 0.873 ppm. For those who don’t, remember that any level in mg/m3 is about 10% less when expressed in ppm.
