Is there minimum gap between items of furniture to enable escape from an office area. For some reason I thought the minimum gap was 1m. The question is not about the actual fire escape corridor but the the notional path to the corridor.

I am not aware of any minimum gaps between furniture however when considering the travel distance you must consider the actual route, around desks, and other furniture, not the direct route. The OSRA require a minimum space for each desk and there is guidance in the new metric book, on gaps between work stations. Check out http://www.docstoc.c...rategy-Document

(you do not need to download the document just go to section 14.)

In this these days of risk assessment I would think its up to the FR assessor to decide if the gap is adequate.
