This danger sign is exactly what you need when there are overhead high-voltage cables above. We placed it at the yard entrance on our small utility site. The sign is very visible even from a distance, which helps alert lorry drivers before they enter. The material feels sturdy, and even after a month outside the print and colours remain crisp. Worth the investment if you value safety
I ordered the vinyl-backed version for a temporary site I was working on. The sign went up easily and looked neat. Over a few weeks with rain and wind it stayed mostly in place, though I’d feel more confident if it were screwed or fixed with bolts rather than relying solely on adhesive. For short-term jobs or as a supplementary warning, it’s fine, but for long-term outdoor use, a rigid-plastic or drilled-mounted version would be safer.
On our construction site we used this sign to warn vehicle drivers and contractors of the overhead cables. The wording and hazard symbol are unmistakable. It’s easy to mount on a wooden post, and despite a few heavy showers the sign shows no signs of fading or damage. Definitely gives extra safety awareness and peace of mind on site.
We mounted this sign to a fence post outside a warehouse near Waterford. The sign looks good and the warning is obvious. However — if the sign is placed too low or in a cluttered area, it might be missed by taller vehicle drivers until too late. It works best when mounted high and clearly visible from a distance. Still, for price and build-quality, it’s a useful overhead-cable warning.
