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.
Sewer gas forms when solid waste from humans and animals decomposes. The gas contains ammonia, methane and hydrogen sulfide, all of which are toxic when inhaled in high concentrations. People can die through asphyxiation when exposed to very high concentrations of sewer gas. More common effects include eye irritation, nausea and breathing difficulty.
