What are the isolation and lock-off procedures or permit-to-work procedure that applies to the equipment being installed or commissioned?

Isolation and lock-off procedures involve ensuring that all energy sources to the equipment, such as electrical, mechanical, hydraulic, or pneumatic, are fully de-energized and secured. This typically requires the use of lockout/tagout (LOTO) devices to prevent accidental re-energization while maintenance or commissioning work is performed. A permit-to-work system may also be implemented, which outlines specific safety measures, necessary risk assessments, and authorization processes that must be followed before work can commence. These procedures are crucial for ensuring the safety of personnel and preventing accidents during installation or commissioning activities.
