In our operation
(a) flight line folk wear hi viz kit - pilots and maintainers alike
(b) if one ventures out without the kit, be prepared for a bollocking from whomever
(c) culture is such that, on the odd occasion when I have so ventured (and I'm the boss-man) I get said bollocking from whomever.
Healthy culture, I suggest.
The aim is not to die or end up in court.
