I was a firefighter for a fair few years, and yeah, 2 minutes. If you can't clear a house of children in 2 minutes... Which tells me that they didn't have fire alarms or that they didn't make sure they were working. And the only thing worse than children is neglectful parents.I work some with Fire safety education - the guidance is once the smoke alarm is triggered (if they had them) you have 2 minutes to get out. YMMV
