You are correct. A bit of panic seems to have set in when this thing started. I’m hearing a number of 50 separate fires in 3 or 4 towns.
What would help a lot if no gas is yet present in a structure would be to put out all pilot lights and turn off the electrical main. You don’t want any open flames or sparks. Open windows to vent.
I just realized that turning of the gas valves would have the benefit of soon extinguishing any pilot lights. After the pressure in the line dropped off.
