Indoor gas leaks: Control ignition hazards
Do not use spark-producing equipment. Use only intrinsically safe radios and flashlights during the incident response.
Do not do anything that could create a spark and ignite the gas. This includes ringing doorbells, using garage door openers and turning electrical switches on and off. Do not step on doormats or shuffle across carpet. Friction from your boots could generate a spark of static electricity.
Call your fire department dispatcher to alert the electric utility if the situation warrants a discontinuation of electric service to a building.
