What is the minimum requirement for an engineer to log operational readings?

The minimum requirement for an engineer to log operational readings is once per shift. This ensures that there is a consistent and reliable record of the operational status of equipment during each work period, which is crucial for safety and efficiency. Logging readings only once per shift allows for regular monitoring, early detection of any anomalies, and enables engineers to respond promptly to potential issues. This practice aligns with safety regulations and standards set by fire safety authorities, ensuring that all operational parameters are tracked throughout the day.

Logging readings once per hour, twice a day, or at the end of the week would be insufficient for effectively monitoring operations, as they would not provide a complete view of the equipment's performance during the critical hours of operation.
