Recommended daily inspections and activities include:

• A. Overfill alarms
• B. Visual checks
• C. Gauge readings
• D. All of these examples

Answer: (D)

Overfill alarms, visual checks, and gauge readings are all part of daily inspections because they cover different angles of safety and operation. Overfill alarms help prevent spills by alerting when a tank is approaching capacity during filling. Visual checks provide a hands-on, eyes-on review for leaks, corrosion, damaged fittings, venting issues, and surrounding hazards that gauges might miss. Gauge readings give the numeric data needed to track liquid levels, confirm inventory, and verify that process conditions match expectations. Relying on all three creates redundancy and a more complete early-detection system for issues, making all of these daily activities essential.
