Industrial Computer Stations & Enclosures work policy

What do standards or some company policy’s say about an IT person accessing industrial computer stations?

I normally label such electronic cabinets as shock hazard only, and blank out the arc flash hazard on the label since over 50v and no arc flash exist.

The IT guy unplugs the computer to remove for service or works on it in the enclosure. The safety person wants to know if that is enough as far as safety.

My reply is as long as he does not touch any exposed conductors. Does he need electrical rated gloves? That does not seem feasible.

The safety person thinks it’s a mistake to put a warning label on such electrical enclosures containing industrial computers and devices what is the consensus?

Thanks for the help in advance.

Over 50V or less than 50V?

Sorry Zog,
I understood what I was asking perfectly
The industrial computer is 120 vac fed from a receptacle in the enclosure.

Unplugged, no safety required, however ESD controls should be used.

120V falls under the avoid contact rule, as long as he does not touch (or any conductive object he is holding) no gloves are required, if contact may be made, class 00 gloves shoul dbe worn for 120V.

Not a mistake at all, a little "over safe" if anything but I would do the same thing you are doing.

Agree with Zog's comments....don't see any difference in unpluging a computer and working on it at the enclosure than doing the same at home. Where could the flash/shock hazard come from?

Zog there is no difference you can do work at enclosure.
its very simple job.
