Locked Shut Signs

Keep locked shut signs are designed to reinforce site security and fire safety protocols in areas where restricted access is essential. Commonly used on electrical cabinets, plant rooms, storage areas, and hazardous zones, these signs clearly instruct personnel to keep doors securely locked, helping to prevent unauthorised access and reduce risk. The premium range of fire safety notices includes keep locked shut signs finished in brushed aluminium for a sleek, professional appearance, as well as durable rigid plastic and self-adhesive vinyl options for versatile installation across different surfaces. The high-contrast designs feature clear, bold lettering and industry-standard safety symbols to ensure the message is instantly recognisable. For added safety in low-light or emergency conditions, photoluminescent keep locked shut signs are also available, offering reliable visibility even during power outages. Built to withstand demanding environments, Firechief® keep locked shut signs combine durability, clarity, and compliance, making them an essential component in maintaining safe and secure premises.
