How to temperature map cold chain equipment and storage areas

For more information on the importance of temperature mapping, the following additional resources may be helpful:

• Cold room temperature mapping studies - This WHO-UNICEF evidence brief provides supply chain managers in low- and middle-income countries with examples of results of temperature mapping studies conducted in an existing cold room to control compliance, and in two newly-installed cold rooms where performance gaps were identified and addressed before vaccine was stored.
• Vaccine Management Handbook: How to monitor temperatures in the vaccine supply chain - This module of the WHO-UNICEF Vaccine Management Handbook focuses on temperature monitoring and provides updated implementation guidance on vaccine vial monitors, and various temperature monitoring tools for cold rooms and fridges, including the new devices which monitor and log temperatures electronically.
