The most successful implementations of 30DTR have devoted considerable time and resources to training but this paid off. Some experts estimate that training and governance could represent as much as 80% of the resources needed for an effective temperature monitoring system based on 30DTR. A lot of material has now been developed and you can find examples in the related resources at the bottom of this page.
Distributing the 30DTR devices without any training was clearly identified as a major bottleneck during early deployments. 30DTR devices are not complicated but their functionality is not intuitive for all. As a consequence there were either not even activated and used or not placed correctly in the refrigerators and health workers did not know how to read them, or at least not how to read the alarms and the information on previous days temperatures.
Based on early experiences, effective 30DTR training should be:
- Classroom-type training with one device per participant (for hands-on manipulation) during monthly meetings or
- On-site training (on-the-job training) during health facilities supervisory visits to provide supportive supervision.
- Training of trainers (or cascading training) can work but obviously the trained trainers should be absolutely clear about the manipulation of the devices. When possible women-to-women peer mentoring could be introduced.
For Health workers at facility level training must include:
- Ability to perform the spot temperature reading for the current day, as well as the reading of minimum/maximum temperature and alarms for a few past days;
- Knowledge of which procedure to follow to take basic corrective actions when 30DTR readings show heat excursion or freeze risk in the refrigerator (for example, check power source, defrost, check the door and door seals, adjust thermostat or make sure the refrigerator is properly loaded allowing air circulation);
- Knowledge of where the 30DTR devices should be placed in the refrigerator;
- Ability to record the 30DTR readings in the temperature monitoring chart.
Extra elements can be added, when necessary either for health workers or supervisors/technicians depending on the distribution and activation strategy chosen:
- Ability to activate and set date, time and temperature scale;
- Ability to change date, time and temperature scale;
- Ability to download data from the 30DTR devices and to understand it;
- Ability to carry out technical corrective action and preventive maintenance;
For health managers or supervisors
On top of the skills above, supervisors/health managers need to be trained in their new routine procedures and checks, that should be recorded in a SOP. The EVM SOP manual provides templates for high level SOPs but these need to be completed by simpler documents for daily use.
- Check that the temperature monitoring charts are filled in and done so correctly (learn how to recognize bogus data);
- Check that extra supplies of the temperature monitoring chart are available;
- Check that the teaching aids are still placed in the correct locations;
- Check that the correct device is still in the correct refrigerator and appropriately placed;
- Check that the correct vaccines are still in the correct refrigerator;
- In order to build accountability, it must be made clear to health workers that these activities are part of the job description and that their performance will be assessed based on these criteria.

This sample Jobaid from from the ColdTrace pilot in Mozambique is a one-page poster on the routine maintenance of refrigerators and corrective measures in case of temperature excursions.
Those one-pagers have been specially developed by PATH to allow in-country cold chain technicians to get at a glance a summary of key maintenance tasks across the various types of cold chain equipment they are handling.
This document provides an example of a table/job aid with suggested actions for health workers in case of temperature alarms in refrigerators.
