600x400mm Poly High Voltage Sign | Electrical Rooms

Unauthorised entry into high-voltage areas creates an immediate safety hazard for staff and visitors. This High Voltage/Authorised Personnel Only sign provides a clear visual barrier, ensuring that only qualified technicians enter restricted zones. It is a necessary addition to electrical rooms, switchboard cupboards, and substation perimeters within industrial workshops or commercial plant rooms.

Installing these safety signs reduces the risk of accidental contact with live equipment by clearly marking the boundary of a danger zone. The high-contrast layout ensures the message is visible from a distance, allowing site supervisors to manage foot traffic and restrict access to those with the correct permits. Because it is made from polypropylene, the sign resists the wear and tear of a busy industrial environment, meaning it stays legible without needing frequent replacement.

This specific model measures 600x400mm and is constructed from durable poly material. The sizing ensures the warning is prominent enough to be seen before a person reaches the door or gate. It is a reliable choice for facility managers overseeing high-risk electrical infrastructure.
