Carbon Dioxide (CO2)
Excess amounts of carbon dioxide found within the air can be a result of unvented gas from kerosene/gas appliances, improperly vented devices, procedures that generate combustion products, as well as human respiration. Various acute health affects linked to CO2 overexposure include difficulty concentrating, drowsiness, and an increased respiration rate. High levels of carbon dioxide can generally indicate that there are also other harmful contaminants present in the air as well. It is advised to perform air quality inspections on a regular basis.
