What are the signs of an LP gas leak?

The signs of an LP gas leak include a hissing sound, the smell of gas, and dead vegetation near distribution lines. A hissing sound is often associated with escaping gas, indicating a potential leak. The smell of gas, described as a pungent or sulfur-like odor, is intentionally added to LP gas to alert individuals to its presence since gas itself is odorless. Additionally, observing dead or dying vegetation in the vicinity of distribution lines can be a clue, as the gas can kill plants by displacing the oxygen in the soil.

While high gas bills and fluctuating pressure could indicate inefficiencies or other issues within the gas system, they are not direct warning signs of a gas leak. Unusual noises from appliances and tanks might suggest operational problems, but they don't specifically indicate a leak. Bright flames and smoke are more indicative of combustion issues rather than a leak itself, and thus do not serve as primary signs of an LP gas leak.
