    Good Heavens - put the knives away and lighten up. It's okay to take the job seriously, just take yourself lightly. The 80% just told you they didn't know where to suggest to look.

    What you are asking about is dead freaking normal through the industry. You might find a housekeeping OSHA regulation. It is not an NEC issue, and likely never will be.

    Interestingly, even this won't make housekeeping an NEC issue. Once the sign gets painted on the transformer, and the inspector is satisfied, that is the end of it. No electrical inspector is going to check back and make sure the house is clean. OSHA might have a fit, the NEC won't.

    I personally don't think stacking stuff on top of a transformer is inherently dangerous. However, I have heard of a bunch of research showing the sloppy workplace have increased accidents. And that makes it worth while to generally cleanup - not just the tops of the transformers.

    Best I could suggest is to read up on a 1000 pages of OSHA regs - unless it is 2000 pages. And it likely won't be in the electrical section.

    However, I suspect the answer is to find a manager with ovaries to step up and say, "We are cleaning this place up. Every day, pickup your work area. Friday afternoon pick up, put away, mop. Everybody is on deck. Areas are assigned." Roll it out slow as a safety issue.

    A couple of my clients do this. Works well. Only two issues I've seen:
    At the start, older journeymen aren't interested - they want the kids to do it. "You're going to pay me to mop." Uhhh, yeah, that's what I said - unless you are telling me you can't do it.

    Management has to schedule time every day for cleaning. Outrageous Example: You got 8 guys and girls. And you want an hour of cleanup every day. You have to hire another person to makeup the 8 hours. What manager is going to suggest that? No, it isn't that bad, but the point is true. If management wants the place cleaned up - they have to pay the bill.

    As for the poor responses, Internet advise is worth what you paid for it. Except for mine. It's worth somewhat less.

    I think the worst part about the example is probably the dust from being a couple feet away from a bench grinder.

    And if you want the crews to stop using the top of the transformer, you are going have to build them a shelf.

    In Canada, fire regulations state that you must have at least 6" from any surrounding walls and at least 36" of clearance after that, also nothing to be left on top of the TX.

    The farther south you go, the colder the air conditioning is set. Some places I work in I have to wear a sweater.

    You are correct that this is the right place. You'll find no finer place on the internet to ask such questions. But you didn't do enough research on us. If you had, you would know that joking around and humorous comments are a normal part of this forum. There was no attempt to offend you. Being responsible, serious, and helpful 100% of the time is tiring and boring.

    Why would this not be considered a violation of 110.26.B, space above electrical equipment?

    (B) Clear Spaces. Working space required by this section
    shall not be used for storage.

    Is the top side of such a unit in the required working space?

    Is there a required working space for all transformers?

    Before you walk in a room that you know has transformers humming, have you ever tried the 60 cycle hum before you enter? I have it down to one to two cycles in pitch! I would screw up if I went to Canada at 50 cycles! lol
