Posted By Stuart Nagle Andrew. As far as I am aware it is not. The only requirments I know that relate to final exits are: 1) Must be unlocked (if capable of locking) during occupation of premises 2) Must be fitted with 'push bar/handle' device if only intended as a fire exit 3) Must open outwards/in direction of travel along fire escape route

Posted By Ken Taylor Whilst the answer will be 'No', as far as Regulations are concerned, you should ensure that the open doors do not present a fire risk from, say, arson by intruders or allowing fire or smoke from a nearby fire to enter the building. I can recall a fire incident in a block of flats where a held-open final exit door allowed smoke from burning material, that had been stored nearby, to enter a stairway and then a corridor by a type of 'chimney' effect and resulted in a fatality and very considerable costs.
