Somehow I missed this thread when originally posted.
I'd just like "chime in" and throw in my 2-cents.
Don you are correct, an extension cord is considered to be temporary wiring. If the tool or equipment is plugged
directly into the wall receptacle, then a GFCI would not be required, but, an extension cord does require the protection.
As an aside MikeP never updated us on this situation, but, Greg may also be correct, which seems like a contradiction of my argument.
The reason Greg may be correct is that the OSHA construction standards are only applicable to activities similar to what Don referenced in his earlier post, which comes from the NEC. The OSHA definition of when this applies is:
1926.32(g)
"Construction work." For purposes of this section, "Construction work" means work for construction, alteration, and/or repair, including painting and decorating.
Maintenance is excluded and is considered to be a General Industry activity and there aren't any similar GFCI requirements in the General Industry standards.
Having said that, it is possible (but unlikely) that a compliance officer may attempt to issue a General Duty Clause citation for failure to provide a workplace "free from recognized hazards." Recognition in this case could be the inclusion of the requirement in the NEC or 70E.
