Which inspection is performed at least annually by a designated person under normal service conditions?

• A. Frequent
• B. Initial
• C. Periodic
• D. Individual

Answer: (C)

Periodic inspections are scheduled safety checks performed at least once a year by a designated person under normal service conditions. They provide a formal review to catch wear, damage, or deterioration before it becomes hazardous, verifying that insulation, grounding, wiring, labeling, and protective devices are in good condition and compliant. This type of inspection establishes an ongoing safety baseline after installation and during regular operation, which is why it’s done on an annual cadence by someone qualified to identify hazards. In contrast, initial inspections happen at installation to establish a starting point, frequent inspections occur more often during use to catch visible issues, and an individual inspection is typically a self-check rather than a formal safety review by a designated, competent person.
