What is the normal ppm of carbon monoxide?
Keeping this in view, what is a safe level of carbon monoxide?
Levels of carbon monoxide exposure range from low to dangerous: 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.
Beside above, is 15 ppm carbon monoxide dangerous? Polluted cities often reach and exceed 9 ppm, increasing incidence of congestive heart failure (Morris). Typical concentration after operation of unvented gas kitchen range (Tsongas). U-L standards for residential detectors require that they NOT alarm at 15 ppm unless exposure is continuous for 30 days.
Considering this, is 10 ppm of carbon monoxide dangerous?
0-9 ppm CO: no health risk; normal CO levels in air. 10-29 ppm CO: problems over long-term exposure; chronic problems such as headaches, nausea. 100+ ppm CO: severe symptoms; confusion, intense headaches; ultimately brain damage, coma, and/or death, especially at levels 300-400+ ppm.
What is the normal level of carbon monoxide in the air?
The natural concentration of carbon monoxide in air is around 0.2 parts per million (ppm), and that amount is not harmful to humans.
