The problem with NEST Protect & other Carbon Monoxide ...

What is interesting about this is I am better protected working on a jobsite than I am at my own house. For example OSHA has a 50 PPM time averaged exposure limit with an automatic removal from the area if the levels ever hit 100 PPM (with the exception of Ro-Ro operations which are capped at 200). The reason for this – the effects of breathing Carbon Monoxide is it blocks the body’s ...

CO2 Sensor Range: PPM and Percentage Compared | …

For smaller volumes, sensor manufacturers and the gas industry measure CO2 and other trace gases in parts per million. For example, % CO2 is equal to 400 parts per million, which is commonly abbreviated as "400 ppm". Indoor Air Quality - 10,000ppm CO2. When talking about indoor air, parts-per-million makes sense.
