Prohibition Signs

Construction Prohibition Signs communicate actions that are not permitted on construction sites and temporary work areas. Also known as prohibition safety signs, restricted access signs or construction site prohibition notices, they help prevent unsafe behaviour and reduce the risk of accidents.

Commonly used by contractors, developers, principal contractors, facilities managers and local authorities, these signs clearly identify prohibited activities such as unauthorised entry, smoking, mobile phone use and access to hazardous areas.

Typical installation locations include site entrances, perimeter fencing, access gates, welfare facilities, storage compounds, high-risk work zones and restricted areas.

Manufactured in the UK and available in durable materials suitable for indoor and outdoor use, construction prohibition signs provide clear visual instructions that help maintain a safer and more controlled site environment.
