Authorities and the utility come first
Smell Gas? Leave Immediately and Call from Outside
If you smell gas or suspect a leak, evacuate everyone rapidly and call 911 and your gas utility from outside the building. Do not operate electrical lights, switches, telephones, or appliances; do not light a flame; do not open or close windows; and do not try to shut off the gas.
Stay outside and do not return until the fire department or gas utility says the property is safe. Jeneral Plumbing is not the first call for an active gas odor, and gas leak detection or repair should begin only after the authorities or utility have cleared the location for entry and work.
Never use a flame, soap solution, electronic detector, wrench, or another do-it-yourself method to search for or repair a suspected leak. The safe sequence is evacuation, emergency notification, utility or fire-department clearance, and then licensed gas-line work when required.
