Hazards/gas Collection
Due to the possible danger caused by containing potentially explosive methane or other gases created by the decomposition of human waste, as well as to provide a more pleasant-smelling outhouse, a ventilation pipe or other arrangement is used to allow the gas to escape. In some cases, the methane may be collected for later use as fuel. see: Methane recovery (gasification)

Famous quotes containing the words gas and/or collection:
“A new father quickly learns that his child invariably comes to the bathroom at precisely the times when he’s in there, as if he needed company. The only way for this father to be certain of bathroom privacy is to shave at the gas station.”
—Bill Cosby (20th century)
“Psychobabble is ... a set of repetitive verbal formalities that kills off the very spontaneity, candor, and understanding it pretends to promote. It’s an idiom that reduces psychological insight to a collection of standardized observations, that provides a frozen lexicon to deal with an infinite variety of problems.”
—Richard Dean Rosen (b. 1949)
