We bought the self‑adhesive plastic version for a small maintenance room in Hamilton. Application was simple and the sign looked neat. However, compared with heavy‑duty metal signage I’ve used before, this feels a bit light. I’d be cautious about using it outdoors long‑term or in places with heavy foot traffic or equipment nearby. For indoor or protected use though — solid enough.
I ordered this sign for our small woodworking shop near Wellington. The wording and symbol are unmistakable and easy to read from a few metres away. Installation was straightforward — we screwed it onto the wall beside the main switch. It gives a clear warning to anyone who might be tempted to mess with the panel, which helps keep safety awareness high. I’m satisfied with the quality and clarity — a great safety addition.
We installed this Danger Mains Voltage sign on our electrical distribution board at our shed in Auckland. The classic yellow and black design with the hazard lightning‑bolt icon grabs attention immediately — exactly what’s needed when there’s live mains electricity. The rigid‑plastic version we chose feels solid and weather‑resistant. Even after weeks with occasional humidity and dust, the sign remains firmly fixed and the print is crisp. Definitely a simple but essential safety measure — worth adding to any place with mains wiring.
We attached the sign to our mains switch cupboard in Tauranga. The warning is clear and the sign looks professional. My only caveat - if you place it too low or behind clutter it could be overlooked, which defeats the purpose. For maximum safety, I’d recommend fixing it at eye‑level and keeping the area around the sign clean and visible. Otherwise, a good, functional danger sign
