The breakdown of natural human waste can cause sewer gas. It has hydrogen sulfide in it and this gives its signature rotten egg smell.  sewer excavation_s

While it isn't toxic at low levels, chronic exposure to or high levels of exposure can result in symptoms of sewer gas poisoning.

Modern plumbing systems have measures in place to protect your property from sewer gas leaks.  Possible causes of a sewer gas smell in your commercial building are usually the result of  plumbing problems.

Expose can occur from leaks in your plumbing system due to improperly installed pipes. It can also leak into your building when plumbing vents are installed too close to a window or air intake.
Leaks from nearby septic systems can also enter your building through cracks in the foundation.

If your pipes are degraded, cracked, or broken, sewer gas can leak through them and into your building.

Toxic gases are diffused away from your building through air vents.  If they are blocked with dirt or debris, they may not be able to vent properly. This can cause sewer gas to build up in the pipes and leak into the building.

Drains transport toxic waste through the system. Clogged drains can cause a sewage backup.
If left untreated, the clog can continue to decompose and leak sewer gas back into the building.

If toilets and drains aren’t used, they can dry out and lose their ability to provide a barrier from harmful gases. If these become dry,  sewer gas can then leak into the property.

To protect against  leakage of gas from the sewage pipes, toilets should always be tightly fitted to the sewer lines.  A gap in the pipes from a loose toilet can lead to sewer gas leaks.

The primary components of sewer gas and the compounds that contribute to high levels of toxicity include:

  • hydrogen sulfide
  • methane
  • ammonia
  • carbon dioxide

 Various symptoms of sewer gas exposure are:

  • fatigue
  • headaches
  • nausea or vomiting
  • dizziness or lightheadedness
  • poor memory and concentration
  • loss of smell (you’ll no longer be able to smell the rotten egg odor of sewer gas)
  • mouth, throat, and lung irritation
  • eye irritation and pink eye
  • seizures
