FULL STORY. Hydrogen sulfide is a foul-smelling gas with an odor resembling that of rotten eggs. Sometimes called swamp gas, this toxic substance is generally associated with decaying vegetation, sewers and noxious industrial emissions.
Methane can form an EXPLOSIVE mixture in air at levels as low as 5 percent. You can smell leaking methane only when commercial gas utility companies add a chemical smell to it or when it mixes naturally with hydrogen sulfide, causing a rotten egg smell. If you can smell it, the level may be too high to be safe.ethane can also be found in coal gas. Pockets of methane exist naturally underground. In homes, methane may be used to fuel a water heater, stove and clothes dryer. Methane evaporates quickly.
