Tell me Martin,

What structure worries you more:
Your office
Ikea
a public indoor arena.

I was involved in a Mass Casualty Exercise as a volunteer trying to evacuate a large old arena in the area.

The ushers and security made it out fine. They were closest to the exits.

(I "died")

I get the heck out, period. Even if the alarm went off every day for a week before that and they were all false alarms.

Is it a real fire or a false alarm? I don't know unless I see smoke or flames. But I'm not betting my life on a hunch. As someone pointed out in the other thread, you have a LOT less time to react than most people think. A lot of people believe they'll have 5 minutes or more to decide what to do. In most major fires, 1 minute would have been pushing it.

I know a lot about fire codes because it's my job. Every four years the NFPA (National Fire Protection Association) comes out with a new code book. And every new version has tons of changes. Know how they come up with these changes? They review every death due to fire, and investigate how the lives could have been saved. They then re-write the codes to include the changes. The codes are said to be "written in blood" for that reason.

That was me talking about how little time one has.

the 90 seconds the Discovery Channel gave was very optimistic.

I would be tempted to ignore a fire alarm if in low risk premises from which escape is easy.
In a higher risk situation I would evacuate promptly.

Low risk IMHO includes ground floor, small simple premises with plenty of exits and daylight.
Small shops, bars and restaurants (ground floor only) especialy if I am familiar with the premises.
The ground floor only of large retail outlets.
Ground level railway stations.

In higher risk premise I would probably evacuate promptly, examples of what I would consider to be high risk include theatres, cinemas and similar crowded places, anything not on the ground floor, and workplaces handling hazardous materials.

I do the same thing!
