Prohibition Signs

Prohibition Signs are used to prevent unsafe behaviour and communicate actions that are not permitted within a workplace or public environment. Also known as no entry signs, forbidden action signs or prohibition safety signs, they help reduce risks by clearly identifying activities that could cause injury, damage or non-compliance.

These signs are widely used by factories, warehouses, construction sites, offices, schools, hospitals, retail premises, contractors and facilities managers to promote safe working practices.

Common installation locations include entrances, restricted areas, hazardous zones, machinery locations, loading bays, fire exits, pedestrian routes and workplace facilities.

Available in self-adhesive vinyl, rigid plastic, aluminium and selected photoluminescent materials, many of our prohibition signs are manufactured in the UK for excellent durability, visibility and long-term performance.
