The Pyromaniac Strikes Again!

We had a tree fall down in some high winds up by the exercise yard.  Phill chopped it up with his chainsaw and it's been sitting there for a couple of months and was an eyesore to say the least.  I walked out to the kitchen to see a big fire burning down there, he's decided to burn them off.  If anyone else was doing this I wouldn't be worried but my husband has a sorry history with setting fire to things.
He once knocked the fondue set over and set fire to the dining table and tablecloth.  Another time I went out and for reasons only known to himself he put the fondue pot on the stove with the oil in it.  He then went to vacuum in the other end of the house.  When I walked in the door, Josh, who was about three at the time looked terrified and couldn't even speak, he just pointed to the kitchen.  The whole stove was alight, it sat in an alcove where the old wood stove used to be.  Phill carried on merrily vacuuming oblivious to the potential disaster.  In my panic I could not remember what you put on an oil fire on an electric stove.  I threw flour on it which of course made it flare up even more.  In the end I just put water on it and managed to put it out.  I was shaking and had to comfort poor little Josh who was traumatised.  Phill continued his housework.  Josh had gone in and tried to tell his father but couldn't make him hear or get his attention.  I got rid of the fondue set.
One night in Western Australia he put a cardboard (??) box outside with cinders from the fire in it.  The next morning I went out the back and a cane stand I had just outside the door was burned to ashes and the cladding on the house was burnt as was the concrete where the box had stood.  If it hadn't rained during the night the house would surely have caught fire.  I got him a metal bucket.
Another time in WA he was burning off in the backyard and some embers went over the fence and set fire to the lane way behind our house.  The neighbours were not amused, neither were the bush fire brigade who had to come put it out.
He put the plastic cutlery tray from the dishwasher on the stove once in Sydney then turned it on.  I had to go and buy a new one, do you know how expensive parts are for those things?
So you can imagine my nervousness.  I'm expecting to hear sirens anytime soon.
