It's picking nits to go into the details of the level, the main point here is that it's difficult to believe that someone could suffer that level of damage at that temperature over a large area, at least conciously. Right off the bat it tells me that 750 large as a payout for it is BS.
I do note that kids seem to be exceptionally vulnerable to relatively low temperature water burns, maybe it's the full immersion VS heat management ability of little bodies, because it seems adults deal with stuff around this range fairly frequently.
A friend of my Mothers slopped a cup of just-shy-of-boiling coffee on my chest when I was about ten, it didn't blister, the skin just fell off. Thankfully, the follicles remained intact, I never needed a chest wig...
Charring isn’t requisite to a third degree burn. The degree rating depends on the depth of the burn.
Most people have never heard of 8th degree burns which I first heard of during EMT training several years ago.
That is actually a burn that goes through and begins to exit the other side.
