Learn More 🚀The Dangerous Chemicals and No Admittance Authorised Personnel Only Dual-Message Sign provides a vital dual safety message — warning individuals about hazardous substances while restricting entry to authorised personnel. Its clear visual design combines a yellow danger triangle and a red prohibition symbol, helping to prevent accidental exposure, legal liability, and site safety breaches.
Commonly displayed in chemical plants, laboratories, industrial cleaning zones, and hazardous materials storage areas, this sign helps ensure compliance with ISO 9001 standards while keeping both workers and the public safe.
Made in the UK from durable materials including 3mm Foamex, Corriboard, aluminium composite, and vinyl, this sign is suitable for both indoor and outdoor use. It’s available in a wide range of sizes and comes with fixing options like self-adhesive, pre-drilled plates, or channel rails to suit your site needs.
This sign delivers two essential warnings in one panel, saving space and reducing the risk of overlooked safety messages. The contrast of yellow and red colour blocks ensures maximum visual impact in busy or high-risk environments.
Engineered for chemical-resistant and weather-resistant performance, this sign maintains clarity and legibility over time — ideal for permanent installations or temporary hazard zones.
