Boiled in water tank

[snopes]

Comment: I have heard many times about a man/men being boiled alive in a
water tank where he/they took refuge against a bush fire. Although i have
read this there is never any solid evidence, eg no names no dates no
states where it happened.I find this hard to believe as i would have
thought if the fire was hot enough to boil the water, you would die from
radiation before boiling alive.
