What equipment isolation and lock off procedures apply to the functional testing activities?

During functional testing activities, equipment isolation and lock-off procedures are critical to ensure safety. These procedures typically involve de-energizing the equipment, securing it with appropriate lockout devices, and tagging it to indicate it is out of service. Additionally, a verification step must be conducted to confirm that the equipment is effectively isolated before testing begins. Compliance with established safety guidelines and protocols is essential throughout this process to prevent accidental startup or exposure to hazards.
