Air Quality Hazards

Vent hoods should exhaust outdoors rather than recirculating contaminated air. Carbon monoxide is presented as a silent combustion hazard that can kill during acute poisoning events. The article says controlled ozone use can sterilize or deodorize empty spaces, but breathing ozone is harmful to the lungs. Standard carbon monoxide detectors may not alert to lower-level chronic exposures that the article links to fatigue, brain fog, and long-term illness. Sewer gas is described as an overlooked indoor hazard that can enter through plumbing defects and may contain hydrogen sulfide and other toxic compounds. Cooking is described as a major indoor air pollution source, especially when frying, cooking meat, or using gas.
