Thanks Bob. It was minor but only because I happened to hear it and so was able to throw water over it just as the flames started. The powder sounds a bit scary, especially as I have young children and all my rooms are relatively small. It is probably worth having though as water isn't good for every fire, I am well aware!
Thanks for the advice. Our neighbours had an overly smokey bonfire at 5pm the other evening so we got to meet a fireman, it's really amazing how out of hand smoke gets.
