I’ve got Skol but I’m not a Scholar
Scary shit, but frankly I've been expecting to see something like this for a long time having seen how some of these systems work, and also worked in buildings where it's clear that many trades don't give a toss about maintaining fire seals when running their cables etc. I remember one job where we were diligently putting the insulation back into the fire breaks around our cables only to look up and see an entire 1.2m wide roof to ceiling strip of fire sealing material missing completely - reported it but I bet it's still missing. I also see they've now exempted soil stacks from being in fire proof enclosures, because a 5 inch plastic soil stack / vent is completely fire proof by itself and in no way would simply burn and create a 5 inch diameter hole in any fire break.
There was a new build block up here in Leeds (private not social) where they had the gas supply running in plastic pipes on the building exterior.
(They did get prosecuted for it, but still)
