Understanding that a flash analysis must be wrought before a definitive response can be rendered regarding the exact type PPE one wears, what are you commercial electricians wearing to protect yourself? What type/ brands / model coats, coveralls? Say for instance-- and once again, I understand the proximity to transformer, service, size of transformer, etc; must be considered.....but what if you need to test a breaker --how are you removing panel covers on 400a panels and testing current and voltage readings now? With what baseline PPE coverage do you consider worthy of entry -PPE?
I'm a licensed electrician and just starting my business. Been out of the field for awhile and just trying to gather some insight into makes of clothing, brands and types, which may be recommended by those in the field. Although Im from the old school where I used to place my left hand in my pocket while working in 480 volt panels with a clean-shanked screwdriver in the right..dumb I know. We all were so ill-informed, sad its taken so many burns for someone to say, "Hey!" Anyway, I'm sure there are enough of those stories to go around by member's of this forum for all.
At anyrate, all of the literature from the NFPA and the sites which sale protective clothing, seemingly make deriving at a choice a daunting task. I'm all for safety and certainly don't mind protecting myself by wearing said gear, just trying to reach a decision on the type which might be a good fit for me and what it is that I will be exposed to.
Working in commercial and industrial environs, leaves me with no other choice but to remove panel covers and check voltages/ measure currents, etc; Let me clarify, I don't plan on working in larger industrial environments, I'm just a one man show for now. There will be opportunity to work in small scale industrial environments for there are a lot of woodworking and machine shops in the region.
As long as I've been doing electrical work 480 has always had my respect. That being said, with all the literature surrounding arc flashes and the depth of studies which have arisen over the past ten years, its left me with a greater concern than I've ever had. Concerns like--what is the probability of arc flashes occurring between meter probes in/and around panel boxes when taking voltage readings....proximities of meter lead probes, even if using the minimal exposure tips (4mm) inside 480 cans? A special concern is- if one is checking phase to phase. I know how I've always done it-on the main lugs as many of my predecessors did and some still do, I presume. But, certainly doesn't mean that's the better approach.
What are your thoughts? Means and methods when working by yourself and such?
