methane gas
Very and highly explosive and carcinogenic
1/8" per foot.
If you experience sewer gas problems, you should report the issue to your local municipal public works or sanitation department, as they are responsible for the maintenance and repair of sewer systems. Additionally, you may want to contact a licensed plumber to assess any plumbing issues in your home that could be causing the problem.
