Like Conqueror I would be happy to offer advice but would need a bit more info to go on.
Like how big is the area outside the logistics area, how far is it from the furthest point of the area to the exit, are there any flammables/ combustibles etc, how many people are present.
It is ok for a room to have only a single exit/ entrance provided there are no high risk items stored or used, no more than about 30 persons and if nobody has to travel more than 18 metres approx from the furthest part of the room to the final exit to the street.
But if it needs to be an exit then keys are not permissible.Theres just far too much chance of things going wrong. But many other solutions are possible- it all depends from which side of the door the emergency exit is required.
