make firesuits not be worthless

[Kovirii]

as long as we're violating the laws of physics on a regular basis there's no reason the firesuits can't be made of super asbestos

How about firesuits protect you for some amount of time, say 30 seconds while engulfed in the fire, and based on some factors like temperature become less and less effective at protecting you?

which should give you super cancer. Put on a firesuit, take massive toxin damage.

If you've been in the fire a long time, or wear one without internals for too long?

We can cut out the cancer, right?
