This video will inform you of the various levels of PPM readings and their meanings. This presentation will also cover the health effects from different leve How carbon monoxide levels are measured Carbon monoxide is measured in a unit called parts per million (ppm). It is a measurement of the amount of CO that is present in a million particles of air. Health effects at different carbon monoxide levels If the level of carbon monoxide in your home is at a normal level, most people won’t experience any symptoms of CO poisoning. The EPA’s limit for air to be considered normal is a CO level of 9 ppm over an 8 hour period and 35 ppm over a 1 hour Carbon monoxide. May 1994. Immediately Dangerous to Life or Health Concentrations (IDLH) CAS number: 630–08–0.

Heat from fire can cause a rapid build-up of pressure inside cylinders. Explosive rupture and a sudden release of large amounts of gas may result. Cylinder may rocket. In a fire, the following hazardous materials may be generated: Very toxic carbon monoxide, carbon dioxide.

Sidorenko et al. (1970) found an indoor level of carbon monoxide of 32.3 mg/m 3 (28 ppm) some two and a half hours after domestic gas combustion began, when there was no ventilation, but only 13.4 mg/m 3 (11.6 ppm) when ventilation was provided.
