LESSON PRESENTATION · 1 / 8

Scope the work order

A reported symptom is the starting point, not a confirmed diagnosis. Before touching equipment, identify the site, asset, complaint, recent changes and access restrictions. Confirm who can authorize the work and whether occupants or critical operations may be affected. A complete work order helps the technician bring appropriate tools and training. If the request is unclear, ask focused questions before dispatch or beginning work. This course develops planning and documentation skills, not permission to perform licensed or hazardous tasks.

Scope the work order

Your goal: Apply the lesson to a realistic situation and explain your decision.

The complaint describes an observed condition. Confirm the cause with an authorized diagnostic process before selecting a repair.

Shutdowns can affect safety and critical operations. Coordinate the impact and obtain required authorization before proceeding.

Correct identification prevents work on the wrong asset. Check the equipment and location against the work order.

Clarification prevents wasted work and unsafe assumptions. Ask about the complaint, asset, changes and access requirements.

A GLI course certificate records introductory learning. Actual work requires the employer authorization, training and any legally required qualification.
