Which of the following best describes the purpose of a permit system in LPWS?

• A. To log maintenance requests after completion.
• B. To authorize and control high-risk activities with risk assessment and approvals.
• C. To schedule supplier audits.
• D. To track energy consumption.

Answer: (B)

A permit system is a formal process to authorize and control high-risk activities through risk assessment and approvals. It ensures hazards are identified, necessary precautions are planned, and only trained, authorized people carry out the work. The permit documents describe the task, location, hazards, required controls, and who is responsible, often including isolation or lockout/tagout steps and ongoing monitoring while the work is performed. This approach prevents unsafe tasks from starting or continuing without the right safeguards and clear accountability.

Other options describe different functions: logging maintenance after completion is simply record-keeping, scheduling supplier audits is about supplier management, and tracking energy consumption is about energy management.
