Ensure fire door security with our Keep Locked Shut Sign—a must‑have in any UK workplace. Featuring bold white text on a blue background, this mandatory safety sign clearly instructs that the door must remain locked, supporting fire safety and compliance under the Health & Safety (Safety Signs and Signals) Regulations 1996, the Regulatory Reform (Fire Safety) Order 2005, and BS EN ISO 7010 standards.

Manufactured in the UK from durable 1 mm rigid plastic or long‑lasting self‑adhesive vinyl, it’s ideal for both indoor and sheltered outdoor use. Choose from multiple sizes to suit fire doors, cupboards or riser rooms. Easy to install with self‑adhesive backing or pre‑drilled options.

Fire safety is a legal responsibility—this essential sign helps responsible persons fulfil their duties and maintain safe evacuation routes. Trusted by site managers, facilities teams and safety officers across schools, offices, and public buildings, our sign delivers clarity and peace of mind—and no chance of accidental access or blocked fire doors.
