Helmet colours identifying roles on a construction site.
Also known as: Helmet colour code, Safety helmet colours, Site helmet convention
Hard hat colours identify roles on a construction site: broadly, white for supervisors and managers, blue for supervised operatives and visitors, orange for slingers and signallers, green for first aiders, and black for site supervisors on schemes that use the British industry convention. It is a convention rather than a rule, adopted by industry agreement and applied differently between countries and companies, so the induction rather than the colour is the authority on any given site.
Identifies roles on a construction site by colour, so that a person needing a slinger, a first aider or a supervisor can find one across a working area without asking.
