AJJewsbury:Your item 4. Why a C2 only for an "escape route"
I was thinking of the BS 7671 idea of an escape route
- Andy.
BS7671 never defined an escape route, then electricians and others tried to apply their own definitions ands in the end it was just easier to make the requirement apply everywhere, says the guy who generally puts fire clips in mini-trunking for new work in airing cupboards which nobody can physically get into.

AJJewsbury:BS7671 never defined an escape route,
My copy seems to - both in 17th AMD 3 & 18th.
- Andy.
Sorry Andy, but 95% of the electricians and designers don't understand that to be a definition or be able to interpret it and they definitely think there can only be one in a house or flat.
Sparkingchip:Chris Pearson:
Bear in mind that most private houses don't have escape routes,I am not picking on Chris, but I rest my case.
My first thought was that the requirement to prevent premature collapse everywhere had rendered a definition of "escape route" otiose, but see 422, which clearly does not apply to ordinary private houses. So a definition is still required.
I could bore you with the difficulties I encountered in getting a licence for a student bar 40 years ago. The problem was that the doors giving access to a designated escape route were not permitted to open outwards into said route. Given that the building was new, one might have thought that the architects would have got that bit right. (The other bit that somebody got wrong was that the ramp into the cellar was so close to the ceiling at one point that even a firkin would not pass. ? )
John Peckham:
Morning Chris
Have a look at the explanatory note on Page 5 in respect of Chapter 52. Then go to Regulation 521.10.202.
Even if you are not in your workshop as you have gone to make an emergency purchase at Screwfix in the event of a fire firefighters may enter your smoke logged workshop in their BA sets to look for you.
Morning John!
The workshop in question is only 12 ft x 8 ft with a 9 ft ceiling. All cables are in PVC mini-trunking.
I understand all about the reasons for the reg and the tragic deaths of firemen in tower blocks, but I don't see that the definition of "premature" is the same for all rooms in all buildings; and maybe not even for all cables in the same room.
So how would you code my cables?
