Which of the following best describes "System Arrangement" in the PQS?

"System Arrangement" in the PQS refers to the organization of equipment and parts of a system. This concept involves how different components are positioned and related to each other within a set system, ensuring that everything functions efficiently and effectively. Proper system arrangement is crucial for both operational efficiency and safety, as it allows for easier access, maintenance, and understanding of the system's functionality.

The other options focus on different aspects unrelated to the structural organization of a system. The layout of emergency exits pertains to safety planning rather than equipment organization. A schedule for watchstanding tasks relates to personnel management and does not concern the physical arrangement of systems. Finally, a protocol for reporting emergencies is focused on communication and response strategies, which are important but distinct from the spatial or systematic organization of equipment and components. Understanding the correct definition of "System Arrangement" helps recognize the importance of having a well-organized system for effective operation.
