Death can occur immediately when a person is exposed to very low oxygen concentrations.

HEALTH EFFECT AND HAZARD DATA The major adverse health effects and hazards from exposure to sewer gases are: Poisoning from H 2 1. S, Asphyxiation from displaced or consumed oxygen, Decreased vigilance or fatigue due to reduced oxygen levels (from CO 2 and CH 4 2. ), 3. Biological contamination, and Fires and explosions from methane gas, H 2 4.

To protect against exposure to this toxic gas, property owners should: Test the air for hydrogen sulfide gas concentrations.
Do sewer gases rise or fall?
