The suit is there to reduce fatalities and minimize injuries, not to avoid every poasible injury.
Sometimes there are situations where touch and feel is critical, although my understanding is that the preferred approach today is remote detonation where even the suit is away from the likely blast radius.
I know someone who used to be a genius and apparently it was uncommon but not unheard of for someone to puncture a battery resulting in a violent fire that had to be put out by dumping a fuckload of sand onto it.
So this isn’t that far off from working at a Genius Bar normally.
