Wow! Some seriously not nice posts/ opinions on here.
I would consider myself a reasonably intelligent person AND I did science at school. Yes, we all know "petrol is flammable" And there are signs at petrol stations re naked flames etc, but I guess I'd never thought about just how dangerous it is. And possibly neither did this woman.
Some of you saying "God, how stupid- has she never seen the signs at petrol stations saying petrol is flammable?" Yeah, I've seen those signs, but nowadays we are so used to everything and anything coming with a warning (there is the same warning on my dd's nightdress, ffs- "flammable material- keep away from naked flame") that we forget the real risks. We are so used to using petrol in a controlled environment that it's easy to forget how dangerous it is when removed from that environment
AS fllighty pointed out, she may not have been aware of how flammable the fumes were- we don't know how close this woman was to the cooker and indeed whether it was a naked flame, so it's pretty harsh to pass judgement, especially since the poor woman is in such a bad way.
I hope she makes as good a recovery as possible, and that this horrible incident reminds people of the real dangers of petrol.
