I'd never quite got this one as most cables are made orf some kind of
plastic,

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

In which case I suppose enough is enough.

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?
