Operational system checks (rounds) are required, with the results recorded on log-sheets, as per the samples found in:

The correct answer pertains to ASME Section VI, which is specifically focused on the recommended practices for safety and operational checks in the field of power engineering. This section outlines the requirements and procedures for ensuring that equipment operates safely and efficiently.

Operational system checks, often referred to as rounds, involve systematic inspections or observations of equipment and systems to assess their current state and performance. The results of these checks must be documented on log sheets to maintain a reliable record of operations and any actions taken. This documentation is essential for troubleshooting, maintenance scheduling, and compliance with regulatory standards.

ASME Section VI emphasizes the importance of these operational checks and the need for thorough record-keeping. By following the guidelines set forth in this section, power engineers can ensure that proper safety protocols are followed and that any potential issues are identified and addressed promptly.
