Can Sewer Gas kill you? Hydrogen sulfide is the primary gas in sewer gas. According to research , hydrogen sulfide has shown to be toxic to the oxygen systems of the body. In high amounts it can cause adverse symptoms, organ damage, or even death .
What happens if you breathe in sewer gas?
This gas smells like rotten eggs, even at extremely low concentrations. Exposure to high concentrations can interfere with the sense of smell, making this warning signal unreliable. At extremely high levels, hydrogen sulfide can cause immediate loss of consciousness and death . Asphyxiation.
How long can you be exposed to sewer gas?
Per OSHA guidelines, the acceptable 10-minute exposure limit of H 2 S is 10 parts per million (ppm). Exposure to 100+ ppm of H 2 S is considered Immediately Dangerous to Life and Health (IDLH). To protect against exposure to this toxic gas, property owners should: Test the air for hydrogen sulfide gas concentrations.
Can sewer gas explode?
Sewer gas can contain methane and hydrogen sulfide, both highly flammable and potentially explosive substances. As such, ignition of the gas is possible with flame or sparks .
Can you get sick from breathing in sewage?
Inhaling the vapors emitted by raw sewage can lead to gastroenteritis, which is commonly associated with fever, vomiting, cramping, and potentially death if left untreated . A more common health concern associated with air-borne contamination caused by sewage is asthma.
How do you know if you have sewer gas poisoning?
However, high levels of sewer gas exposure can occur in industrial workplaces. The symptoms include: loss of smell (you’ll no longer be able to smell the rotten egg odor of sewer gas) mouth, throat, and lung irritation .
Is the smell of sewage harmful?
Answer: Only under extremely unusual circumstances. Although hydrogen sulfide is a toxic gas, it will not harm people at the concentrations that exist in a house with sewer gas odor problems . Studies have shown that hydrogen sulfide has a depressant effect on the central nervous system in concentrations above 150 ppm.
What happens if I breathe in methane?
High levels of methane can reduce the amount of oxygen breathed from the air. This can result in mood changes, slurred speech, vision problems, memory loss, nausea, vomiting, facial flushing and headache . In severe cases, there may be changes in breathing and heart rate, balance problems, numbness, and unconsciousness.

Can septic tank smell make you sick?
Is It Dangerous? Fortunately for us, we can generally smell Hydrogen Sulfide (H2S) at very low levels and far below what could be toxic so smelling the gas does not always mean that it will make you sick . However, at higher levels, your nose can become overwhelmed by the gas, and we lose our ability to smell it.
How long does it take to get methane poisoning?
Even a 1-minute exposure to a high concentration of methane gas in a sealed room was enough to cause loss of consciousness. There was a case report that describes induced hypothermia used as a treatment for comatose state in a patient with asphyxia caused gas intoxication including methane6.
How much methane is lethal?
Asphyxiation becomes a risk when there are high concentrations of methane. This is because the methane displaces the oxygen. We need approximately 18% oxygen to breath, levels below 16% can be dangerous and levels below 10% can cause immediate loss of consciousness and inevitably death.
Does sewer gas rise or sink?
Sewage gas is heavier than atmospheric gas and it “sinks” to the lowest level in the house or in a room . The sewage gas smells are caused because somewhere within or outside of the house, the rotten egg smell is not being vented and so it starts to accumulate.

Can septic tank gases explode?
The most common reason that septic tanks explode is the methane gas . The organic matter that ends up in your septic tank breaks down, as it should. This process is called Anaerobic Digestion and it produces methane gas, which is combustiable and can explode. That’s why it’s recommended to NOT smoke near septic tanks.
