Reviews
he sign itself is well made — bold hazard symbol, clear “Danger High Voltage” text, quality print. We used it on an electrical cabinet in our facility. My only minor criticism: for more open spaces or larger areas, the standard size we ordered might be a bit small. If mounting near a wall or door it works perfectly, but if you want to warn drivers or people from a distance, you might need a larger format. All in all, a dependable hazard sign if placed right.
I ordered the “Danger High Voltage Electrical Sign” for our electrical switch-room door and it looks excellent. The material feels sturdy (we went for the 3 mm aluminium composite version) and the print is bright and easy to read from a few metres away. It’s visible even in dimly lit areas, which is important near live panels. Installation was straightforward — we drilled it onto the door and it’s stayed put through regular site traffic. Solid sign and good value, especially considering the peace of mind it gives about site safety.
We used this High Voltage warning sign at a small substation facility in Ontario. The rigid-plastic version we selected is weather-resistant and held up well through rain and cold weather. The wording and the lightning-bolt hazard symbol are unmistakable - very clear hazard communication for workers and visitors. We positioned it where anyone entering the area sees it immediately. Very satisfied with quality and usefulness.
his Danger High Voltage sign from RainbowSafety gives our plant a more professional look while ensuring safety compliance. The text and symbol are crisp and legible from a distance; no blurring or fading even after weeks outside. We mounted the 1 mm rigid-plastic version on a metal fence near the transformer enclosure, and it’s survived wind and dust without damage. A simple but essential safety board - absolutely recommend for any electrical installation.
