Cables and reaction to fire

lyledunn
Why do you suppose that the MHCLG did not feel it necessary to mandate levels of performance for cables with respect to their reaction to fire as was their prerogative under CPR?

Clearly the current non-prescriptive approach is either working or there is no significant evidence that cables and wiring systems have unduly contributed to the propagation of a fire or resulted in emissions that made a situation untenable when it would not have otherwise been. 

Further, what does it actually mean in the note in 422.2.1 that cables need to satisfy the requirements of the CPR in terms of their reaction to fire? I can find nothing specific in the CPR other than the need for CE marking and the requirements placed on the manufacturers for technical information.

    ps On the whole I agree with all that you said, though having been in hotels where the fire alarm has gone off I generally find myself wondering, as I wander towards the assembly point, whether everyone else in the building is happy to be burned alive - you can only do so much to protect the other occupants.


    Very true Alasdair...


    Working for a previous employer and a workman while cutting off bolts in the warehouse floor inadvertently set fire to a stack of boxes (sparks flying everywhere caused a slow smoulder that then escalated rapidly). Alarm activated and everyone evacuated. During the roll call a colleague was found to be missing. Fire Brigade turn up and on entering the building find said colleague sitting in the canteen eating his sandwiches.... ?


    I believe a formal warning was issued.
