The smell in sewers is gasses given off by the sewage such as methane.
Too much of this sewer gas can mean that you cannot get enough oxygen and die.
Awful.
Awful.
If you think you smell sewer gas in your bathroom, it could be that a sewage blockage is in your pipes, causing the sewage to back up in the lines.
There is no permanent health effect of sewer gas odors but it can make one nauseated to smell the odor.
If it is a sewer gas, you can detect it with a combustable gas detector.
Call the police, fire dept or Con Edison or all 3.
Perhaps a gas leak? The gas we use for cooking is originally odourless, but a smell is added during manufacturing to let us know if there is a leak, and this smell is most commonly sewer-like.
One of the biggest culprits I have found for sewer gas smell is the floor drain many floor drains are seldom if ever used and if unused long enough the water in the trap will evaporate allowing sewer gas to enter the dwelling. this also applies to any trap which is not used regularly.
If you are on a septic system, it is plugged.
Heck no as it is a very carcinogenic mixture
It can kill you if you smell too much of it.
No its not able to kill a person because fart is natural gas
