A blue flame is hotter than a yellow flame. First, "...the blue flame..." IS NOT more dangerous than "...the yellow flame."

The reason this is dangerous, actually DEADLY, is that when combustion [burning] occurs in an oxygen deficient atmosphere, one of the major byproducts of that combustion process is CARBON MONOXIDE, a colorless, odorless, and tasteless gas which is toxic and therefore deadly to any creature that breathes air.
