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.

Which poison is called a silent killer?

Carbon monoxide (CO) is frequently referred to as the "silent killer" because it is a colorless, odorless, and tasteless gas. It is impossible to detect through human senses alone, which is why it poses a significant safety risk in residential and commercial settings.
