That’s a good idea, but if you’re not an employee of some kind (perhaps intern in some fields) it’s just a loss for them. If you’re lucky you might get a day or two, especially if there’s grunt work you can do in trade, or you might know someone who can grease the rails a bit. Otherwise, you can likely pay for the privilege if there aren’t significant safety (may break insurance policies) or legal (confidentiality etc.) issues. Best you can do is ask, perhaps repeatedly in different places.
