How much time do I have to escape a fire in my home?

There often is very little time between the detection of a fire and the time it becomes deadly. This interval can be as little as 1 or 2 minutes. -NFPA 72-2010

If you’re trying to exit a home in a free-burning fire, fully involved like a living room or a kitchen or something like that, I would imagine that if you’re not out of the house within the first minute or two, you’re finding yourself in a position where you may not ever get out of that house. -Bill Kennedy, Fire Chief, Ret.
