Casques de sécurité bleus

If you are visiting a construction site that follows the head protection colour coding rules set out by Build UK then you will almost certainly be asked to wear a blue safety helmet. A blue hard hat meaning is defined by Build UK as being worn by someone who is a visitor or does not fall into the other key groups of users.

By wearing a safety helmet in blue you are quickly and easily identifiable as a visitor. This is important as it can vastly improve the safety standards on construction sites and can help site managers keep track of where visitors and unskilled operatives are.

If you are working on a network rail site then you will only see blue, black, and white safety helmets. The blue safety helmet has the same meaning on a Network rail site, with white also still indicating a competent operative.
