Danger - Back of this Panel Is Live Labels - Safety Signs by Caledonia Signs

These labels are used to warn personnel that the rear side of an electrical panel remains energised, even if the front or accessible areas appear de-energised. This label plays a crucial role in preventing accidental contact with live components, which can lead to severe electric shock, arc flash, or even fatal injuries.

The primary reason for using this label is to highlight hidden electrical hazards. In some cases, only part of a panel may be isolated, while the back or internal terminals remain live due to their connection to other active circuits. This warning alerts maintenance staff and electricians that extra caution is needed when opening or accessing the rear of the panel.

These labels are typically placed on the front cover of electrical panels, switchboards, control cabinets, and enclosures where the back side remains energised. They are especially important in industrial, commercial, and utility settings, where complex wiring or busbar systems are common and partial isolation is a possibility.

Using “Danger – Back of This Panel Is Live” labels supports a safer working environment by preventing false assumptions about electrical isolation. It reinforces proper lockout/tagout procedures, ensures compliance with electrical safety regulations, and reduces the risk of injury for anyone performing maintenance or inspection tasks.
