Simplify Analysis
In a perfect world, your team would fully analyze every failure, identifying the root cause and contributing causes with pinpoint accuracy. Unfortunately, the realities of time and money don't make this feasible.

Traditional failure analysis procedures exceed what's reasonably achievable in the field. A tech confronted with a complex, time-consuming post-mortem procedure won't follow it, especially when there are fires to put out.

The solution is to create simple procedures that repair techs can use to quickly collect relevant data, plus do basic diagnosis. They might find only contributing causes this way, but at least they’re doing something post-mortem. When you aggregate the data of several repairs, you can focus limited resources for root cause analysis on the problems identified by trending.

NEC in the Facility
Provide adequate overhead clearances from buildings to overhead service conductor final spans. The NEC doesn't allow you to run these conductors under openings through which materials might move or where they might obstruct such openings [230.9].

The NEC also requires that conductors maintain a vertical clearance of 3 ft from doors, porches, balconies, etc., and from windows that open. That distance isn't nearly as much as it might seem. If you want to ensure you're protecting someone who's standing in a door or opening a window, allow for that additional distance.

Safety
Where can you take breaks? On construction sites, electrical rooms often serve as makeshift breakrooms. From an industrial hygiene standpoint, this is a bad idea because it introduces food and thus vermin into these spaces. From an electrical safety standpoint, it's not an immediate problem if these rooms don't contain energized equipment. However, taking breaks in such rooms with energized equipment unnecessarily exposes you to flash and arc blast hazards.

Even if you took breaks fully decked out in a flash suit (not likely), just being in the area introduces unnecessary risk. Always take breaks in areas specifically designated as breakrooms.
