How safe is the fuel?

This film shows what happens if a candle is knocked over but doesn't go out

I set this situation up to show what might happen If a wick comes out of a candle and it doesn’t go out witch of course ninety-nine times out of a hundred it will so it just sits on the deck there and it burns quietly its pretty much just absorbing the fuel because of course the wick wont really burn without fuel so I’m even gonna try to pour a bit more fuel down here there you go now the flame doesn’t really come into contact with the fuel because of the way it sits and the um bottom part of the flame here is quite cool so it never ignites the paraffin because as I said it wont burn without a wick
