What is the meaning of standard operating procedure?

• A. A random checklist
• B. An informal rule book
• C. A government tax regulation
• D. A documented way of working or arrangement of facilities at the coal mine to achieve an acceptable level of risk, developed after consultation with coal mine workers

Answer: (D)

A standard operating procedure is a formal, documented method for how to work and how facilities are arranged to achieve an acceptable level of risk, developed with input from coal mine workers. It guides day-to-day tasks, equipment use, and safety controls in a consistent way, ensuring the operation maintains safety as a priority and that workers’ experiences are reflected in the procedures.

This is the best description because it emphasizes both the written, standardized nature of the method and the goal of managing risk in the mining environment, built with input from those doing the work. A random checklist lacks formal structure; an informal rule book isn’t official or consistently applied; a government tax regulation is unrelated to mining safety and operations.
