What is the purpose of maintaining calibration records for cold chain equipment?

• A. To ensure thermometers/refrigeration equipment remain accurate and within specified tolerances.
• B. To track energy consumption.
• C. To schedule maintenance visits.
• D. To calibrate staff understanding.

Answer: (A)

Maintaining calibration records for cold chain equipment ensures that temperature readings are accurate and stay within specified tolerances. In the cold chain, vaccines and other sensitive products must be stored within strict temperature ranges; even small sensor drift can push conditions into unsafe territory, potentially compromising potency or causing spoilage. Calibration records capture the results of checks, any adjustments made, and the equipment’s adherence to standards, providing proof for regulatory audits and internal quality control that the readings you rely on are trustworthy. They also help spot drift over time, triggering timely recalibration or servicing before problems arise. While such records can support maintenance planning, the primary purpose is to verify accuracy of measurements, not energy use or staff training.
