Can sewer gas set off the gas alarm ?

Sewer gas is mostly methane and ___anes are explosive for the most part. So yes. We call it a "Propane Detector" but it is truly and explosive gas detector.

Methane (Farts/Sewer)
Alcohol
Gasoline
Butane
Propane
and a host of other things that go BOOM if the air/fuel mix is right.
