Natural gas is a fuel mixture composed mainly of methane. Building supply systems and appliances require appropriate installation, maintenance and emergency response.
What this means at your property
A suspected fuel leak takes priority over cleanup or damage documentation. Do not stay inside to trace an odor, operate switches or test equipment. The absence of an obvious smell should not be used to dismiss an alarm or other warning.
What is the immediate next step for a suspected leak?
Leave the area and contact emergency services or the utility from a safe location. Return and arrange repair or restoration work only after the responsible responders have addressed the immediate concern.
