My question is whether an inoperative door qualifies as an entry, and thus needs a 7.5 m buffer area. My project site holds large events and needs to create a temporary fenced smoking area to accomodate large amounts of people for a short amounts of time (one evening a month for example). Does a smoking area need to be 7.5 from an entry if the door is locked and no one can enter or exit this door? Doing this seems to be the only way to satisfy this prerequisite, and hoards of people needing a smoke...
