Thanks for your reply Tom. And for the link. It's actually myself thats been tasked with the job of carrying out a fire risk assessment, but my experience is quite limited so i'm trying to gather as much information regarding the legislation as possible. With regards to the government guidance attached in your response, it seems to suggest that as long as the fire risk is normal i.e. offices with small numbers of people, that predominantly employees use the building, that there are alternative means of escape and that travel distances are within the suggested distance described in Table B, Page 68; then fire doors may not be deemed a requirement? The building is of typical layout, although the stairs are not protected, the travel distances are well within the recommendations in the above mentioned table and most if not all persons in the building will know the layout. There is L1 fire alarm coverage as well. I'm thinking the inner room, kitchen and head of the stairs are the only rooms that require fire doors?
