Danger Mind Your Head sign
Warnings for every hazard. Electrical, flammable, gas, chemical and trip hazard warning signs for workplaces and sites. Made in the UK in 3 materials: rigid plastic, aluminium or high-tack sticker. Free UK delivery.
Which size do I need?
Each size reads at a different distance. Measure the space before you choose a larger size. A good rule: 1 inch of text height = 25 feet of viewing distance.
Choose your material
Rigid plastic1.2mm rigid plastic is light and waterproof, for indoor and outdoor use.
Aluminium (Dibond)3mm aluminium Dibond is a rigid aluminium composite panel - heavier and stiffer, our toughest option for exposed sites.
High-tack stickerThe high-tack sticker grips even rough, hard-to-stick surfaces.
Easy to fix
Fix rigid signs with screws, cable ties or double-sided tape; pre-drilled holes are available on request. For a sticker, clean and dry the surface, then peel and press firmly.
