Having worked for a REC/DNO , the only time I have needed Gloves and face mask is when pulling porcelain rewirable fuses with old cast iron enclosures or when I pulled reyrole fuses that supplied a whole tower block ,,
The training is though to use them all the time when pulling main fuses,,,

I should add to that that any other PPE is also to be used if required and the other requirement was long sleeved fire retardant polo shirts etc ....

I've just had a cheque from EDF for a meter change gone wrong (invoiced 3 months ago mind). My client of many years rang up saying night storage heaters not working and no hot water and that also meter had been changed day before. Get there and found E7 Contactor Tail left out and put in a Henley on its own. As it had just been tagged I told him what it was and I said ring them up. He said two guys from EDF were there for 2.5 hours the next day? They said they had never seen such a system but they did it in the end. Amazing.

Half the time they send out guys who are jointers or guys that have no knowledge of the metering side at all , and what I hear these meter monkeys haven't a clue, not like the old guys , I have worked with guys that where on stand by every 6 weeks , that didn't have a clue about metering and general wiring and controls like contactors , time clocks , tele switches or the newer tele meters , I often wondered how they got on when on standby , quite often it was a case of we will get someone else during the following day to attend ..
 
He had the gloves and shield on, I expect he was looking at you peculiar because you were stood next to him and did not :). They often never ask to isolate round here. Also I have temp seals from SSE (10 at a time), I inform them and they re-tag when convenient

So MM, PPE will save you from arc-flash will it?

PPE is secondary protection, knowing what you are doing is the prime consideration.

I’ve been involved in sorting out the aftermath of two arc-flash incidents. The first one fortunately no one was in the room, if there had been there would have been nothing left of them.
The second occasion the lad ended up in hospital for quite some time and he had full PPE. Caused simply by a terminal shroud being missing.

It’s about time you took a step back and think about what you are about to say before you say it.

Quite right too, there will always be no substitute of knowing what your doing along with experience ,,
PPE is to no avail without that,,

ppe would have done nothing for this poor guy
 
Seen that clip many times, it doesn’t get any better.

There are a few operational mistakes made that contributed to the aftermath. The cause from what I can gather is the breaker wasn’t fully open, not knowing the gear involved I can’t comment.
All the gear I’ve worked on it’s virtually impossible to operate the isolation mechanism unless the breaker has fully opened.

Arc-flash is a topic all of its own.
 
Where I work we have circuit breakers that break around 30,000 amps
It is very important to make sure that breakers close and open fully as we have problems with them sticking part way arc flash is taken very seriously
