My day job as an E & I Tech. in a chemical plant has a very in-depth, although not necessarily always followed, procedure manual for working on electrical systems. This policy works in conjunction with NFPA 70E. Unfortunately, it took 3 deaths before any formal policy was implemented at all.
This policy includes everything from LOTO to flash suits and designated flash-zones. Mostly, to test or diagnose anything 240 volt or below, you must wear leather gloves and safety glasses, anything over that, voltage-rated gloves, flame-proof clothing, and an arc-shield for facial protection at a minimum. This is a VERY simple overview of the policy. If anyone is interested in this sort of program, let me know, and I will send copies of our procedures.
