As a firefighter, if you’re too obese to be extricated from a burn, you will be left.
It doesn’t mean we won’t try our hardest to get you out, but it comes to a point where it’s not worth a whole crew for one person.
And it’s not that we don’t want to save them, it’s that we literally can’t. The heat, the weight, and obstacles all culminate to make it damn near impossible to move a morbidly obese victim.
