AMD2 - Clause 422.2 - Cables in protected escape routes.

pww235 over 3 years ago

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?

I think this is one of the biggest changes that has far reaching consequences. In my field - railways, this is a huge change.

Protected escape routes can only be defined by the Responsible Person (RP) for the fire safety of the building, not the electrician or designer. So the RP will need to be consulted so as to ascertain where the protected escape routes are. Without that information, the designer will have to detail the lack of this information in their designers risk assessment and move on.
