What Is a Photoluminescent Keep Locked Sign?

The Photoluminescent Keep Locked Sign is a mandatory glow-in-the-dark safety notice used to indicate that a specific door, cabinet, or area must remain locked at all times. This helps control access and maintain safety in high-security or hazardous environments.

Charged by ambient light, this sign illuminates clearly in darkness, power failures, or smoky conditions—making it ideal for low-visibility areas. It plays a critical role in UK workplace safety, especially for doors to electrical rooms, storage units, or chemical stores.

Available in standard sizes—100×100, 200×200, and 300×300 mm—this sign is UK-manufactured and ISO 9001-certified for quality, performance, and durability.
