What must be done before starting maintenance on equipment?

Before starting maintenance on equipment, it is essential to verify de-energization and perform a tag-out procedure. This step ensures that all sources of energy to the equipment are properly isolated and that it is safely inoperative before any maintenance tasks begin. This process protects workers from unexpected energization, starts, or the release of stored energy, which could lead to serious injuries or accidents.

The verification of de-energization involves checking that the equipment has effectively been disconnected from its power source. Tag-out provides a visual indicator that maintenance is being performed and alerts others not to energize the equipment while work is ongoing. Overall, performing this crucial step establishes a safe working environment and complies with safety regulations and best practices in maintenance operations.
