Emergency doors must not be so locked or fastened...

[Messy]

I would be careful if only considering designated fire exits during a FRA. I am not saying all exit doors must be a fire exit, but all routes to a place of safety should be assessed

People will use any door to the outside as a final exit , whether its signed as a fire exit and official or not

This is why fire alarms must have manual call points by every exit from a building - including loading bays etc, in order to meet the requirements of BS5839-1

I said I was out, but your post requires a further comment.

You're not explaining why anyone would lock the door behind them with a key while there were people inside!
If there's nobody inside when the door is locked, this whole thread is irrelevant.

Are you relaying in human behavior?

Because Mr.M is afraid that someone could try to get in to grab the car keys and the wallet. In fact, almost home time.

Apparently, no one was left inside, but Mr.F was doing protecting time in one of the meeting rooms. In fact, he was using one of the lasted headphones with noise-canceling for not getting distracted.
The roll call was conducted and believed that Mr.F left earlier since he wasn't seen since lunchtime.

Mission impossible?!

Totally agree.

Well it's not helpful to be drip fed aspects of the scenario.

There is still not a satisfactory explanation, because now you make it sound as though this door is never available for use from the inside, because people are always unlocking/locking it from the outside.

The more you throw titbits of the scenario in, the more confusing it becomes.
