Acid

A DANGER sign reading “Acid”, with the red DANGER oval on a black band above black lettering.

• Materials: self-adhesive vinyl or aluminium
• Sizes: 300 × 225, 450 × 300 or 600 × 450 mm

Self-adhesive vinyl sticks straight onto a clean, smooth surface like a door, wall or cabinet. Aluminium is tough and rigid, so it suits outdoors, gates and fences, and anywhere a sign might cop a knock.

Pick the size for how far away it needs to be read from, and if you are between two, go the bigger one.
