I'm a consultant who specializes in industrial hygiene issues; no expert in electrical safety at all.

I have a client who has a LO/TO program which is in woeful shape. I'm giving them some advice about getting up to speed, and one of the issues that I raised was the lack of labeling (with regard to purpose) they have on their electrical disconnects. Talked to them about it.

Someone raised the issue that this requirement [29 CFR 1910.303 (f)] doesn't apply to circuit breakers. I disagree, at least from a safety perspective.

Thoughts? Opinions?

Appreciate the advice greatly.
