Hi, to assist in completing a fire risk assessment can anyone offer guidance on the most suitable documents for assessing multi storey external plant with open grid stairways and walkways etc.   These are open to the elements.   The CLG suite of documents has fire safety risk assessments: factories and warehouses, but are there more relevant guidance documents which I can research and apply??

Thanks

I am not aware of such a document but I would imagine the are other similar situations. It is now all about fire risk assessment so if you are experience enough simply apply fire safety principles and active fire safety devices. 

Hi Tom

Thanks for your reply, I have found some useful guidance in BS9999.  If any one needs it please look at Annex F (normative) Process plant and outdoor structures on Page   355.

Unfortunately I do not now have access to that document anymore.
