Question

According to the nfpa, the upper human survivability limit is approximately:

Answer 1

The National Fire Protection Association (NFPA) states that the furthest reaches of human temperature viability is 212°F, well beneath temperatures found in most noteworthy structure fires that are past the development (early) stage. In the present fire conditions, temperatures higher than 500°F can be effortlessly gotten inside three to four minutes. Flashover, which happens at roughly 1,100°F, can grow well under five minutes.2 If a space isn't legitimate for firefighters, caught casualties aren't probably going to survive either. Set aside the opportunity to make it safe and keep your firefighters from going for broke.

 

60% of the casualties were found to have been presented to warm (most at temperatures over 200°F; some were beneath) and mugginess for six to seven minutes (remote from the fire range).
