Learn More 🚀The Danger High Voltage and No Admittance Authorised Personnel Only Dual-Message Sign is a vital safety display designed for electrical hazard zones and restricted areas. Combining a yellow high voltage triangle with a red no admittance panel, this sign delivers two critical warnings to protect workers, contractors, and the public from risk.
This sign is ideal for use in substations, switchgear rooms, electrical panels, construction zones, and industrial facilities. It helps site managers comply with ISO 9001 standards and reduce liability by warning of high voltage and enforcing entry restriction for non-authorised individuals.
Manufactured in the UK using premium materials including 3mm Foamex, Corriboard, composite aluminium, and vinyl, this sign is weather-resistant and suitable for both permanent and temporary use. Available in multiple sizes with mounting options like self-adhesive backing, pre-drilled holes, and channel rails.
This dual-message sign saves space while enhancing clarity. The bold icons and colour contrasts maximise visibility from a distance, ensuring safety protocols are understood before entry.
Its durability and customisation options make it a top choice for utility companies, commercial contractors, and facility managers needing to display essential electrical safety information.
