Hazardous Area and No Admittance Authorised Personnel Only Dual-Message Sign – Two-in-one safety message sign for high-risk zones. ISO 9001 compliant and durable.
Professional design, supply, and installation of all types of traffic signs across the UK.
Learn More 🚀The Hazardous Area and No Admittance Authorised Personnel Only Dual-Message Sign provides a bold and efficient way to communicate two critical safety warnings in one sign. Combining a yellow hazard triangle with a red access prohibition panel, this layout alerts viewers to both danger and entry restriction — helping maintain full compliance with UK site safety regulations.
Ideal for use in chemical plants, electrical facilities, workshops, warehouses, and construction zones, this sign ensures only authorised personnel may enter potentially dangerous environments. It supports ISO 9001 safety management standards and reduces the need for multiple signs on limited wall space.
This sign is manufactured in the UK from durable materials like composite aluminium, Corriboard, Foamex, and adhesive vinyl. It’s available in a range of sizes and fixing options including self-adhesive backing, pre-drilled plates, and channel rail systems — suitable for temporary or permanent placement indoors or outdoors.
With its two-part visual message, this dual-message sign provides layered protection: alerting workers or visitors to a hazard and reinforcing that only authorised personnel may proceed.
Its layout maximises space efficiency and reduces the risk of overlooked warnings, making it a preferred option for high-risk workplaces that demand clarity, control, and compliance.
