Fair enough. He put on his polycarbonate glasses. Still fair enough.

Then, he donned thick elbow length rubber gauntlets, plus a full face
polycarbonate shield. THEN, he removed the main fuse.
Given that he had turned off the consumer unit, this struck me as
excessively cautious, but what do I know?

Clearly not as much as you think.
He was taking adequate precautions against the fuse carrier/fuse/cut-out
falling apart when he pulled it.

I can see the need to do this with some old installations but is it
necessary with current designs of main fuses?

If you have the gear to hand, why would you *not* do it? It must be all
of 20 seconds extra to put on the gloves and visor.

Yes, if you have the PPE gear available it makes sense to use it but I
was wondering if lack of suitable PPE would be a reason to not pull the
main fuse from a modern cutout.

In other words which would be the greater risk on a modern domestic
installation. Working inside a consumer unit with its main switch turned
off but still live at the input side or pulling the main fuse after
switching off the consumer unit main switch.
