What is the primary purpose of a permit-to-work system in a facility's maintenance program?

• A. To schedule routine maintenance activities in advance.
• B. To document employee training records.
• C. To authorize and control high-risk maintenance work by isolating hazards, assigning responsibilities, and ensuring controls before work starts.
• D. To track inventory levels for spare parts.

Answer: (C)

The main idea here is that a permit-to-work system formalizes and controls high-risk maintenance tasks by requiring authorization, hazard isolation, defined responsibilities, and pre-work safety measures before any work begins. It ensures that energy sources are locked out or otherwise isolated, that appropriate controls are in place for the specific hazards (like hot work, confined spaces, fall protection, or hazardous atmospheres), and that the person in charge has reviewed and signed off on the plan. This creates clear accountability and an auditable record that everything necessary to keep workers safe has been arranged prior to starting the task.

This approach isn’t about scheduling routine activities, keeping training records, or tracking spare parts. Those are important, but a permit-to-work system specifically targets ensuring high-risk work is planned, hazards are controlled, and work is authorized only when the controls are verified.
