Danger — High voltage — Isolate elsewhere before opening

Product Description

Identify the electrical warning clearly with this “Danger — High voltage — Isolate elsewhere before opening” sign. The artwork combines a yellow electrical lightning bolt warning triangle above wording with the printed message, giving staff, visitors and contractors a recognisable notice at the relevant location. Select this design when the voltage, equipment or situation described in the artwork matches your installation.

Position the sign where the complete message can be read before people reach the affected equipment or area. Keep it visible on the normal approach and avoid placing it behind objects or competing notices. Review the display when the equipment, access arrangements or workplace layout changes, and replace missing or damaged signs promptly.

Choose from three finished sizes: 150 × 200 mm, 300 × 400 mm, 450 × 600 mm. Match the size to your mounting space and viewing distance. The original artwork is fitted proportionally, with white margins where needed to preserve the entire design and its printed message.

Four materials are available: Self Adhesive Vinyl, 3mm PVC Foamboard, 4mm Fluted Board and 3mm Aluminium Composite. Vinyl provides a sticker for a suitable smooth surface, while the board options provide a separate panel. Choose a suitable fixing method for the material, surface and conditions at your installation location.

Order your preferred size and material combination for a new display or a replacement electrical notice. Coordinate it with suitable isolation, access-control and first-aid signage where relevant to your premises. This is standard printed signage. It supports your own site procedures and competent-person arrangements; the product does not include electrical equipment and is not a substitute for isolation, maintenance or staff training.
