I don't know how new the regulations are, but at least they cut down on gas mishaps. It'll let some gas flow but then kills that flow after a certain amount of seconds where no ignition is present.Yeah I keep them in a coffee can with the camping equipment. I wouldn't ditch the camp stove anyway even if I did switch the kitchen to gas cooking. Can't take the kitchen stove camping...
It was definitely around when I bought this house and remodeled it. I'm guessing it's a 90s regulation. Prior to that, any place or stove I used had a pilot light. When the range we had then was installed, I asked where the pilot light was and the guys looked at me like I was an absolute weirdo.
