Reviews
The sign works nicely on our electrical distribution box — bold, clear, and looks professional. But if placed too low or on a cluttered wall, it’s easy to miss. So for maximum effect you have to think about placement (eye‑level, clear of obstacles). For inside rooms or fenced-off electrical cupboards it’s sufficient and gives a good warning.
We mounted the sign on a metal panel in our warehouse in Hamilton. It sticks and stays put even after a few weeks, through dust and occasional damp conditions. The warning text and symbol are clear. The only drawback is that the board feels a bit thin compared to more heavy‑duty signage, so if I were installing in a very industrial or outdoor environment with frequent knocks, I’d consider upgrading to a heavier material.
Ordered this “Danger 240 Volts” sign for our maintenance room door in Wellington. The print and hazard icon are crisp and unambiguous, so there’s no risk of someone misunderstanding the risk. Installation was easy — we used screws onto the metal panel — and after several weeks it still looks new. Having a proper hazard sign helps ensure we meet safety standards and reminds everyone to stay cautious around live wiring.
We put up the Danger 240 Volts sign on the electrical cupboard at our workshop near Auckland. The bright yellow and black design with hazard symbol makes it instantly noticeable - even in dim light. The material feels sturdy and weather‑resistant, so it stood up fine when we mounted it outside next to the mains panel. It’s a small investment but gives a strong safety impression - would definitely recommend for any site dealing with mains voltage.
