No Access Signs

No Access Signs are prohibition signs used to restrict entry into specific areas and prevent unauthorised access. They provide a clear visual instruction that access is prohibited, helping businesses improve safety, security and operational control throughout their premises.

Commonly referred to as Restricted Access Signs, No Unauthorised Access Signs, Access Prohibited Signs or Authorised Personnel Only Signs, they are widely used in factories, warehouses, construction sites, offices, schools, hospitals and public buildings.

Manufactured in the UK, Rainbow Safety's range of no access signs is available in self-adhesive vinyl, rigid plastic, aluminium and photoluminescent glow in the dark materials. Suitable for indoor and outdoor use, these signs help clearly identify restricted areas and support workplace access management procedures.
