Our superb range of Mandatory signs are part of the Regulatory Infrastructure and are a powerful way to encourage staff, visitors and contractors to follow safety procedures.
A "mandatory sign" means a sign prescribing behaviour. These signs are required to be blue. A mandatory sign shall show only what action is required. Mandatory signs generally use a white safety symbol on a blue background. Mandatory safety signs are not, as some people believe, 'those which are required by law'.
