News: Measuring Carbon Dioxide (CO2) Why you cannot use Oxygen measurement to comply with CO2 exposure limits
For Immediate Release:
|0.50%||5,000||20.80%||OSHA CO2 PEL|
|3.00%||30,000||20.27%||NIOSH CO2 IDLH|
|6.70%||66,986||19.50%||OSHA 02 PEL|
|13.88%||138,756||18.00%||NIOSH O2 IDLH|
Drowsiness leading to confusion and labored breathing occurs with increasing CO2 exposure above 2,000 PPM. Ambient air is about 350 PPM CO2. Zeroing a sensor on ambient air means your reading is 350 PPM. Low Oxygen Alarm values are 19.5% (warn) and 18% (evacuate). When the CO2 IDLH of 3% is reached, the Oxygen level is not near alarm but the effects of 3% CO2 are severe headaches and confusion!
