Before conducting maintenance on equipment, it is essential to ensure safety by turning off the power to the equipment. This step is critical as it prevents accidental startup or electrical shock, creating a safe working environment for the technician. De-energizing the equipment eliminates the risks associated with moving parts, electrical hazards, or stored energy that could be released during the maintenance process.

While reviewing the maintenance log, testing the equipment, or inspecting the surrounding area may be important steps in the overall maintenance process, they should come after ensuring that the equipment is powered down. Safety is paramount, and turning off the power is the foundational step that enables any further inspection or maintenance activities to occur without risk to the technician's safety.
