Technical work documents include which items?

• A. Maintenance procedure, formal work packages, controlled work packages
• B. Wiring diagrams and schematics
• C. Training manuals
• D. Safety data sheets

Answer: (A)

Technical work documents are the written guides that tell you exactly how maintenance work should be performed. The best example here is maintenance procedure, formal work packages, and controlled work packages. A maintenance procedure gives the step-by-step actions, required tools, parts, tolerances, and safety measures to complete a task. A formal work package outlines the scope, sequence, needed manpower, schedule, and acceptance criteria for a job, providing a clear plan. A controlled work package is a formal work package that’s under change control, with approved revisions and restricted distribution to ensure everyone uses the current instructions.

Wiring diagrams and schematics are essential references for understanding electrical layouts, but they aren’t the task-ready instructions for performing work. Training manuals are for teaching skills and knowledge, not for guiding a specific maintenance task. Safety data sheets provide hazard information about materials, not the procedural steps to do the work.
