What details are included in complete operating records for screening equipment?

Complete operating records for screening equipment are crucial for proper maintenance and operational efficiency. The correct answer includes the date of inspection, the amount of material removed, and notations regarding debris. Each of these elements plays an important role in understanding the performance of the screening equipment.

The date of inspection helps identify when the last check-up occurred, allowing operators to schedule regular maintenance and mitigate potential issues before they escalate. Keeping track of the amount of material removed is essential for evaluating the equipment's effectiveness and determining if it is working within its designed parameters. Notations regarding debris provide context on the type and quantity of material being screened, which can indicate changes in influent quality or reveal specific operational challenges that need addressing.

In contrast, the other options do not include the comprehensive nature of the necessary records. For example, simply recording the last maintenance date and the amount of material removed might overlook important operational insights that could be gleaned from inspection notes. Similarly, while knowing the types of machines used and their performance metrics can be useful, it does not provide the same level of detail needed for effective maintenance management. Therefore, the inclusion of inspection dates, material removal amounts, and debris observations encompasses a more thorough understanding that is vital for operational success in managing screening equipment.
