1 When sewer gases diffuse into household air, they gradually displace oxygen and suffocate occupants. 2  The effects of oxygen deficiency include headache, nausea, dizziness and unconsciousness. 3  At very low oxygen concentrations (less than 12%), unconsciousness and death will occur quickly and without warning.
Another common source of sewer gas is a broken drain line that allows sewer gas into a crawl space, basement or mechanical area, which then seeps into the office, factory, warehouse, apartment, etc. Plugged or backed up drains can also push sewer odors back into the air. Besides the offensive odor, sewer gas can be hazardous especially over any extended period of time. Methane gas can displace oxygen, especially in a confined space, and be deadly. Hydrogen sulfide is also toxic.
