Oh dear Lyle,
That doesn't sound too good, but things like this CAN and DO happen, I had a situation a few years ago, where I burnt a good sized hole in a customers carpet with a soldering iron, I went out to the van to get a few connectors and was talking to the nieghbour, meanwhile the iron had slipped offthe top of the wirestrippers that I had sat it on(the flex was all twisted up).
Brand new carpet too and out in the middle of the room.
Never going to be that stupid again!!.
