And don't they even add something to the gas so that you can smell it ? They do that here

you can smell it, i just have a really crap sense of smell at the mo so it took me ages to notice

Well, that's atleast some comfort, that you can smell it - or, if you can't, hopefully others can

you need to be careful with the gas A friend had a incident where their next door neighbours house exploded because of gas building up over several days; luckly they weren't in themselves as it took half their house out too we need a smiley >big I had some today for teh first time in.... oooo maybe four or five months .... problem is.... I ate one bar.... gave one to my lodger... ate another bar...... now there is one left Oooo how long can i resist it?

what on earth is an 8 year old doing lighting candles sweetie?

I think you need to make sure they are not accessable, or goodness knows what could happen....
