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. [7] The methane concentration in open sewers is lower (7 to 15 ppmv) than the closed drains (up to 300 ppmv) in samples collected 2 cm (0.8 in) above the level of sewage. [8]
Symptoms of carbon monoxide poisoning Carbon monoxide makes it difficult for you to breathe. It reduces the ability of blood to carry oxygen to your organs, which means your brain and blood won ...

[11] In the United States, approximately 200 people die each year from carbon monoxide poisoning associated with home fuel-burning heating ...
A gas leak refers to a leak of natural gas or another gaseous product from a pipeline or other containment into any area where the gas should not be present. Gas leaks can be hazardous to health as well as the environment. Even a small leak into a building or other confined space may gradually build up an explosive or lethal gas concentration. [1]
Methanol toxicity (also methanol poisoning) is poisoning from methanol, characteristically via ingestion. [1] Symptoms may include an altered/decreased level of consciousness, poor or no coordination, vomiting, abdominal pain, and a specific smell on the breath. [1] [2] Decreased vision may start as early as twelve hours after exposure. [2]
