What must be done before conducting repairs on a system?

Before conducting repairs on a system, tagging out is a crucial step that ensures safety for workers and prevents accidental operation of the machinery. The tag-out procedure involves placing a warning tag on equipment to indicate that it is not to be operated until repairs or maintenance are completed. This serves as a communication tool, informing all personnel that the equipment is undergoing work and should not be activated.

Implementing tag-out protocols is part of a broader safety initiative known as Lockout/Tagout (LOTO), which aims to protect maintenance workers from unexpected startup of the machinery or the release of hazardous energy. By following this procedure, workers can work safely, knowing that others are aware of the ongoing repairs.

While notifying a supervisor, draining fluids, and wearing protective gear are also important considerations in the maintenance process, they typically follow the initial tagging out of equipment to ensure that the working environment is safe. Tagging out establishes a baseline for safety before any other actions are taken.
