Refrigeration equipment temperatures must be recorded how often?

• A. Once per day
• B. Twice per day
• C. Every hour
• D. Once per week

Answer: (A)

Regular temperature monitoring of refrigeration units is essential to protect stored materials and catch any equipment problems early. Recording the temperature once per day provides a consistent, auditable log that meets typical QA expectations for routine operation. It balances practicality with safety, ensuring there’s a daily record of the reading and any excursions or corrective actions.

Recording more often, like twice per day, is often a higher standard than the minimum for routine labs and may be required only in specific circumstances. Checking every hour is generally unnecessary for standard use and imposes extra workload, while once per week leaves too long a gap to reliably detect excursions or failures.
