The term describing keeping apparatus in a state of usefulness and readiness is

• A. Calibration
• B. Maintenance
• C. Inspection
• D. Repair

Answer: (B)

Maintenance is the process of keeping equipment in a usable and ready-to-operate condition by performing regular servicing, adjustments, lubrication, part replacements, and scheduled checks. This ensures the apparatus remains functional and available when needed, reducing downtime and improving reliability. Calibration, on the other hand, focuses on adjusting instruments to meet accuracy standards. Inspection is about examining condition to identify issues, which can lead to maintenance or repair but is not the ongoing practice of keeping equipment ready. Repair is the actions taken to restore equipment after a failure. For a fire apparatus, routine maintenance might include checking fluids, tire pressure, hose integrity, and pump performance to ensure readiness for operation.
