Hi all,

I was wondering if anybody has experience and/or could point me in the direction of any authorative guidance or exisitng strategies? 

I have a client who has got themselves into a pickle by not considering how their roof-top emergency generator will be serviced and maintained, including refuelling. I have explained their designer should have considered this as part of their design (CDM Regulaton 9) and suggested where properly planned, a suitably protected fuel line would normally have been part of the original design.

However we are where we are and now they are proposing methods such as carrying the fuel internally via the internal staircase. I have commented this is unlikely to be acceptable and should be subject to thorough risk assessment to confirm, and to be considered by  the client's Responsible Person whom will be responsible for ongoing building safety, under the RRO Fire Safety.

Any real world examples of strategies I can use going forward would be greatly appreciated!

Thanks in anticipation!

David.

We ran two buildings with on roof generators

Building No 1:  We owned and it was a large building with a proportionately large genny on the roof. We installed a double skinned riser pipe within a fire resisting enclosure up through 13 floors of the building to feed the rooftop tank. The outer layer of the pipe was charged with compressed air, so leaks in the outer skin were monitored 24/7

Building No 2 was also a large 10 storey multple use commercial premises where we were tenants of a small demise, but one with critiacl IT. We carried fuel through the building out of hours when the building was virtually empty.  The fire risk was low, but spillage risk higher and in any case the landlords wanted to keep corporate clients in suits and a grubby drum of fuel separated
