Well your welcome. My advice, would be to get out during any gas emergency. Call 911/ gas company let them check it out. My experience is mostly with minor leaks at the stove etc.

Not many earthquakes in NY ! Now that could cause some broken pipes and explosions. Your basic "is that gas I smell" type leaks well there is little to fear. A broken pipe inside is the real deal just leave.

BTW the gas will rise, and the highest readings will be the upper floors. When we vent a house we open the top floor windows and a lower door.

The funny part is we park the firetruck a house away so if it blows the city is not out a truck I guess, we send just 2 guys with full ppe,scba etc. Then the gas company comes, parks in front and a guy in a t shirt and pants hops out smoking a cigartte........
