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.

    Couldn't agree more. If you change the cable but do nothing about all the wooden furniture, etc. that hotels insist on putting in the rooms then the improvement in the event of a fire is minimal when you take into consideration the amount of cabling you are looking at. Specifying LSF cables is only part of the solution.


    Sure - but we all have a part to play - and most items in an hotel room will have classifications for ignitability and surface spread of flame - plus detection and alarm that should ensure the limited number of occupants are roused and can evacuate to a place of relative safety (ie the corridor) - and the door to the room plays an important part in containing the fire. Selecting the correct cabling plays an important part in protecting that corridor for other occupants should that room compartment be breached.
