Be sure to follow the rule before you head out.
Rule: You must post before you leave.
TIL there are colour-coded helmets on worksites. Makes sense, I suppose. If you need a first aider or something it's probably easier to look for a particular colour helmet than just Jim.
A lot of the time you don't even know Jim, never met him. So wearing the hat for what your job is let's people know who to ask for what without everyone needing to know each other.
