We wear orange on the railways and yellow if it's civils/roads.
I am back to working in water and waste water plants (wear it all started for me). I love it and since the company I work for is on the smaller side the safety feels more like a culture and not a religion. Its nice being able to boot a guy out that's an unsafe idiot and not making everyone else pay for some other dummy.
I understand hard hats, gloves, glasses, and safety toe but some of the safety stuff is crazy. Go to work in a petrol/chem plant, they dont mind if a group of guys sit and do nothing if some college grad who graduated 2 days ago deemed it "unsafe" but will not help to resolve the situation.
