That list could be pretty long if your a contractor and somewhat shorter if you sign on with a utility. The guys we hired brought their belt,hooks , climbing boots. Then we made sure that equipment was up to snuff. They needed a nine inch Kline pliers, a good screw driver, a folding rule, and a skinning knife. We supplied leather gloves, rubber gloves, protectors, sleeves, a hard hat, safety glasses. They also could check out rubber boots, a rain suit, and a hiVis vest.
tools like bolt cutters hack saws, large hammer, lag wrenches etc were stocked on trucks, or you could check that stuff out also.
you could get ear plugs or muffs, sun screen that was not harmful to the rubber goods. There was hand lotion for cracked dry skin also.
everyone was given an allowance to purchase FRC clothing, including shirts, pants,coats, overalls etc.
if I remember right you had to purchase the preferred fall arrest system and harness, but like belt and hooks were replaced by the company when they wore out.
there may be things I missed but good luck with your new career
