Learn More 🚀The Caution High Voltage and Keep Out and No Entry Triple-Message Sign delivers a powerful safety warning using a combination of caution, mandatory, and prohibition symbols. Designed to keep unauthorised personnel away from dangerous high-voltage areas, this sign communicates three essential safety instructions in a single, space-saving display.
Ideal for substations, power rooms, plant facilities, and electrical enclosures — this UK-manufactured sign meets ISO 9001 compliance and is built for durability and clarity. It uses high-contrast colours and universally recognisable icons to ensure maximum visibility and recognition on any site.
Manufactured using robust vinyl, Corriboard, Foamex, or composite aluminium, this 500×300 mm sign is available with multiple fixing options including adhesive and drilled. Its weather-resistant design makes it suitable for both indoor and outdoor use.
This triple-message sign features a yellow triangle for high voltage, a blue “Keep Out” circle, and a red “No Entry” prohibition symbol. Each message reinforces the others, creating a clear multi-layered safety directive that supports hazard avoidance and access control protocols.
Perfect for any site that requires strong electrical safety communication.
