"No Unauthorised Persons" Prohibition Sign

Step confidently into safer workplaces with the “No Unauthorised Persons” Prohibition Sign. This indispensable safety sign draws a clear line between public and private areas, helping you maintain control over restricted zones at a glance. Designed for swift deployment, it fits seamlessly into any setting—be it corporate offices or industrial yards—to reinforce your security protocols.

By combining instant visibility with robust construction, it safeguards sensitive locations—from server rooms to construction sites—without the need for complex installation. Its clear messaging helps prevent accidental breaches and enforces strict access protocols at all times. Backed by materials built to last, this sign delivers reliable performance day in, day out. 

Manufactured in durable 1 mm PVC or as high-tack self-adhesive vinyl, this sign adapts to your specific environment without compromise. Choose PVC for long-term outdoor resilience against sun, rain and temperature changes, or opt for vinyl when you need rapid, tool-free mounting on rough or low-energy surfaces. Both options deliver the same crisp text and symbol quality, ensuring maximum legibility.

This versatility lets you roll out consistent safety measures across diverse settings without juggling multiple product lines. Whether applied to concrete walls, metal doors or plastic panels, the sign stays firmly in place. As a result, you save time on installation and maintenance, while keeping your workforce protected. 

The matte surface minimises reflections under bright overhead lighting and direct sunlight, keeping your message readable from any angle. By reducing glare, staff and visitors can absorb critical safety instructions at a glance, even when moving swiftly through busy areas. This anti-shine treatment also resists smudges and fingerprints, maintaining a professional appearance over time.

Whether placed indoors in warehouses or outdoors on fencing, the finish ensures your sign remains legible in all conditions. Regular cleaning won’t dull its warning message or impair visibility. You can rely on its persistent clarity to support ongoing safety and compliance efforts. 

Peel away the backing of the self-adhesive vinyl and press firmly in place—no drills, screws or fixings required. This tool-free mounting method saves time across multiple locations, letting you secure access points instantly without disrupting daily operations.

For scenarios demanding a more permanent fixture, the lightweight PVC version slips neatly into place with minimal effort, requiring only basic hardware. Both options deliver fast deployment and immediate functionality, ensuring restricted zones are clearly marked from the moment they’re needed. 

Designed in a 300 (H) x 200 (W) mm portrait format, the sign provides clear instructions without overwhelming narrow doors, machinery panels or fence posts. Its space-saving profile integrates neatly into busy environments, maximising visibility while keeping walkways and workstations uncluttered.

This balanced footprint ensures the message remains prominent at eye level without obstructing adjacent signage or safety equipment. As a versatile addition to your site’s visual hierarchy, it supports orderly traffic flow and enhances overall compliance with access restrictions.
