Warning Power Supply Has Been Locked Off Sign

The Warning Power Supply Has Been Locked Off Sign is essential for informing staff and contractors that an electrical power source has been safely isolated and locked out. This sign helps prevent accidental reconnection or operation of equipment during maintenance or servicing, significantly reducing the risk of electric shock or injury. It supports the safe application of lockout/tagout (LOTO) procedures and reinforces a safety-first approach in any work environment.

Ideal for use in engineering plants, manufacturing facilities, workshops, and construction sites, the Warning Power Supply Has Been Locked Off Sign provides a clear visual alert to everyone on-site. When displayed near control panels, isolation switches, or machinery, it helps ensure that energy sources are not restored until work is complete and proper authorisation has been given.
