career guy here, i ride the engine backwards mostly, but if someone calls out or something they can ship me out to another piece in the city, but usually i stay in-house.
as far as stuff in my pockets,
heavy duty mechanix gloves
protech 8 titan gloves (my personal set
blazefighter gloves (dept issue, spares now)
one of those folding knives with the window punch and seatbelt cutter
some door chocks
couple sprinkler wedges
our gear is morning pride only, with the ranger rubber boots. they give us the morning pride helmets, but they sit wicked high on your head, so alot of guys buy their own leather helmets, like i just did with mine, cairns n5a new yorker, and i attached a rubber strip with a hole for my flashlight.
but everything aside, carry some wirecutters and a knife in your gear. you need to be able to save yourself, that is paramount
