The OSHA personal exposure limit (PEL) for CO is 50 parts per million (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.

One ppm is equal to 0.0001%: 1ppm = 0.0001%. ppmw PPM is a simple format for storing images portable pixmap: color (PPM), grayscale (PGM) and black and white (PBM). These formats can provide an intermediate representation of the data when converting raster image files listed three types between different platforms. PPM … The health effects of CO depend on the CO concentration and length of exposure, as well as each individual's health condition. CO concentration is measured in parts per million (ppm). Most people will not experience any symptoms from prolonged exposure to CO levels of approximately 1 to 70 ppm but some heart patients might experience an increase in chest pain. minutes when the CO concentration was < 25 ppm and was 1 sec when the CO concentration was 75-100 ppm.

Source should be identified, might be normal (ie, traffic, kitchen range) (Energy Conservatory). 9 ppm. The maximum allowable concentration for 8-hour period in any year, EPA (ASHRAE).

Its measurement works like a percentage. The percentage is based on a scale of 100. If there was 1 percent of carbon monoxide gas in the air in your home, it would read as 10,000 parts per million. P9-11-84 Mix ; AG19; Reactive Multi-Mixtures.
