What is the normal CO level in a home?
|Level of CO||Health Effects, and Other Information|
|0 PPM||Normal, fresh air.|
|9 PPM||Maximum recommended indoor CO level (ASHRAE).|
|10-24 PPM||Possible health effects with long-term exposure.|
|25 PPM||Max TWA Exposure for 8 hour work-day (ACGIH). Pocket CO TWA warning sounds each hour.|

Also to know is, what is the normal carbon monoxide level in a home?
Average levels in homes without gas stoves vary from 0.5 to 5 parts per million (ppm). Levels near properly adjusted gas stoves are often 5 to 15 ppm and those near poorly adjusted stoves may be 30 ppm or higher.
Subsequently, question is, 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.
Keeping this in view, what level of CO is dangerous?
As CO levels increase and remain above 70 ppm, symptoms become more noticeable and can include headache, fatigue and nausea. At sustained CO concentrations above 150 to 200 ppm, disorientation, unconsciousness, and death are possible.
What is the safe limit for carbon monoxide?
[OSHA PEL] The current Occupational Safety and Health Administration (OSHA) permissible exposure limit (PEL) for carbon monoxide is 50 parts per million (ppm) parts of air (55 milligrams per cubic meter (mg/m(3))) as an 8-hour time-weighted average (TWA) concentration [29 CFR Table Z-1].
