In indoor environments, space heaters fueled with oil, gas or kerosene, gas stoves, combustion appliances and tobacco smoking are known to cause significant emissions of carbon monoxide. The WHO recommended limits are: 9-10 ppm for no more than 8 hours. 25-35 ppm for no more than 1 hour.
What is the legal limit of carbon monoxide?
What are the OSHA standards for CO exposure? The OSHA 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.
What level of carbon monoxide is safe and unsafe?
Low level: 50 PPM and less. Mid level: Between 51 PPM and 100 PPM. High level: Greater than 101 PPM if no one is experiencing symptoms. Dangerous level: Greater than 101 PPM if someone is experiencing symptoms.
