This Fire Door Keep Locked Sign—a premium square safety sign—is a must-have for ensuring compliance across UK workplaces. Designed for non-photoluminescent contexts, it clearly communicates mandatory safety instructions where keeping fire doors locked is essential for passive fire protection.

Ideal for riser cupboards, service areas or storage rooms, this sign supports responsible persons under the Regulatory Reform (Fire Safety) Order 2005 and Building Regulations to prevent unauthorised access and maintain fire door integrity. It also meets the Health and Safety (Safety Signs and Signals) Regulations 1996, following colour and symbol standards set by EN ISO 7010 and design guidance from BS 5499.

Made from durable materials suited to both indoor and sheltered outdoor use, the sign delivers long-lasting clarity and professional aesthetics. Its simple, bold layout ensures visibility and reinforces best-practice fire safety routines. With its clear mandate to 'keep locked', this sign plays a vital role in reducing fire risk and supporting swift, safe evacuation procedures.
