Carbon Monoxide Levels Chart | CO2Meter.com
WEBThe alarm thresholds, set by CO concentration measured in parts per million (ppm), are: no alarm below 30 ppm until after 30 days; 70 ppm for one to four hours (but not less than one hour); 150 ppm for 10 to 50 minutes; 400 ppm for four to 15 minutes.
Carbon Monoxide Levels - Kidde
WEBFor a person to begin feeling the effects of carbon monoxide poisoning, they would need to be exposed to a carbon monoxide level of 50 parts per million (PPM) for eight hours. Different carbon monoxide detectors will sound at the detection of varying CO ppm levels.
Carbon Monoxide Fact Sheet | CPSC.gov
WEBAs 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.
How Do Carbon Monoxide Detectors Work? - NIST
WEBAug 23, 2021 · These detectors are designed to measure the concentration of carbon monoxide in the air (in parts per million, or ppm) and sound an alarm if enough of the chemical is around long enough to become a problem. If detected over the course of a few hours, carbon monoxide at 70 ppm will trigger an alarm.
Carbon Monoxide Acute Exposure Guideline Levels
WEBThe CO levels in homes are usually lower than 9 ppm; however, the peak value in homes could be up to 18 ppm with gas stoves, 30 ppm with wood combustion, and 7 ppm with kerosene heaters. The CO concentrations inside motor vehicles are generally 9-25 ppm and occasionally over 35 ppm.
Carbon monoxide poisoning - Symptoms and causes - Mayo Clinic
