I had to put a piece of wood behind all the knobs after one of my dogs managed to turn on the gas twice on me. The second time the house reeked and I had to do the airing out thing. The non-guilty dog spent the next two days throwing up due to the gas. Thankfully there was no lasting damage. There's a picture on my blog of how I installed the wood.
