Afternoon, I am installing some outside playground seating at a school. This will be in an area which is used by pupils when exiting the sports hall and going to their fire evacuation point on the field. Are there any rules about how big a gap I would have to leave between the seating. To confirm this is outside, once they have left the building via the final fire exit.

It will depend on the width of the exit doors in sport hall, any seats adjacent to the exit doors, you must ensure there is an equivalent distance between the seats so person exiting the exit doors will not be impeded by the seats.
