Have you ever think about Meaning of colour in helmets on the construction site?
Colors are important because it allows you to easily define what a given person does.
Black helmet - author's supervision inspector or architect;
Green helmet - OHS worker;
Orange helmet - surveyor;
Red helmet - apprentice, intern or guest;
Yellow helmet - manual worker;
Blue helmet - an electrician, machine operator, energy specialist or a person who works at heights;
White helmet - supervision inspector, engineers (including construction engineer) and construction manager.
In Poland the law does't say enything about the obligation to submit to such a coloration,but in fact every self-respecting company in Poland follows this color scheme.
