Posted By Ed Carter David as far as I remember, and dependant on circumstances such as numbers of persons etc. it is; maximum direct distance from any point in a room to room exit 12m maximum distance between fire doors in a corridor 30m Unprotected corridor: maximum distance room exit door to protected route/stairway 18m maximum direct distance from any point to protected lobby/stairway alternative exits or final exit 30m Protected corridor:30m any point to lobby/staircase, alternative exits final exit 42m (Source Building Bulletin 7) Hope this is of help.

Posted By David White Thanks very much Ed, much appreciated.

Posted By Ken Taylor The principle in operation here is that (as per Approved Document B to the Building Regulations) direct distance is to be taken as 2/3 travel distance when layout and fittings are unknown. Table 3 of B1 gives maximum distances for a range of types of premises for both single direction and more than one direction of travel. Generally for one direction these range from 9m for institutional, bedroms and places of special fire hazard through 18m for offices, shops, commercial, schools,recreation, etc to 25m for industrial and storage premises. It is also notable that BS5588 Part 11 may be used instead for new defined small workplaces. If still in doubt after reading the literature, a question to the local fire officer would be advisable!
