What type of personnel protective equipment should an electrician own and use, when working on electrical systems under 600 volts?

Joe, 70E is a fair document, very concise. Myself, i like the charts & tables, which is a good overview , or place to start.

T 2-1.3.4 Approach Boundries to Live parts for Shock Protection, pg 70E-51

Flow Chart, 'Hazard/risk analysis procedure flow chart, pg 70E-72

These might be a good place to start discussing this concern, note the decision making process starts at 50 Volts!
perhaps this could be scanned & posted???

Does OSHA have any rules related to NFPA 70E and the 2002 NEC, Section 110.16 for Flash Protection?

When will OSHA adopt more recent standards such as the NEC?
I do not see why not, economically speaking, for a meager $30+ dollars 70E will proliferate the trade quicker, and not much to ask for during appreticeship.
