gas leak

In common usage, a gas leak refers to a leak of natural gas or other gaseous product from a pipeline or other containment into a living area or any other area where the gas should not be present. Because flammable gases may explode when exposed to flame or sparks, this situation is very dangerous to the general public. In addition to causing fire and explosion hazards, leaks can kill vegetation, including large trees, and may release powerful greenhouse gases to the atmosphere.
