metal cable clips, 18th edn
 

Metal cable clips are required for cables that could otherwise collapse in a fire in an escape route. My question is, can one use just enough of them to keep the cable there in a fire, or does every single clip have to be metal?

Enough to stop the cable drooping to get in the way of anyone trying to
get in/out of the entrance/route.

I'd never quite got this one as most cables are made orf some kind of
plastic, In which case I suppose enough is enough.

Sure, but its better if they don’t fall down and
obstruct the movement of people in a fire.

When a flat in a tower block in SOuthampton caught fire, the
firefighters wearing breathing gear got ensnared by cables that
had drooped down from the ceiling because the trunking and or
clips had melted.

Metal core inside the plastic. Plastic & clips burn away, leaving copper
wires.

or a bent nail in lieu of the occasional cable clip.

A problem with that kind of approach is if you end up abrading the cable
with thermal expansion cycling.

OK, the nail can be sleeved :) It's 10mm2 main earth bond cable.
