AMD2 - Clause 422.2 - Cables in protected escape routes.

pww235

Evening all,

So, this is causing me some head scratching. Why oh why did this make it through the DPC?

As soon as an escape route is required to be of fire rated construction, we can't use it for main containment routes. Or am I missing something?

  • From what I recall from the webinar a protected escape route is a very particular kind of escape route - designated by whoever is in charge of the fire design - and is likely to be places like sterile fire stairwells where's there's nothing but steel and bare concrete - rather than an ordinary corridor that happens to need 60/90/120-minute rated walls or whatever

    What I didn't quite follow is what you're supposed to do where there isn't a modern fire precautions design (say rewiring an existing building) which might have something fairly similar but was never formally described in those terms and you've no-one to ask.

    The provided definition of "protected escape route" in Amd.2 is woefully sparse if that is the case.
