Site Prohibition Signage

Site prohibition signage clearly communicates actions that are not allowed across your premises, helping you control behaviour and prevent unsafe activity in restricted or hazardous areas. Recognised by its red circular design with a diagonal bar, these signs are widely used to highlight rules such as no entry, no smoking or no unauthorised access on construction sites, warehouses and industrial environments.

Using site prohibition signs helps you reduce risk, enforce site rules and ensure clear communication of restrictions to staff, visitors and contractors. Ideal for entrances, work areas, access points and controlled locations, these signs provide clear, immediate instruction where it matters most. Available in durable materials such as rigid plastic, aluminium and self-adhesive formats, they are designed for long-lasting visibility in demanding environments.
