I'm sure most of you would have found out... ----------------------------- This message contains a contribution from Søren Spanner (mailto:[email protected]) ___________________________________________ As for the control of the temperature in the fridge, ILR and freezer it can be controlled by an electronic thermostat and that is readily available and installed in some appliances. All new equipment should be fitted with an electronic thermostat, that will control the temperature as long as electricity is available. Without electricity there is nothing much to do other than what can be helped with the ice-lining, gen-set or solar power. The thermostats should not be user adjustable. For cold climate areas, it would be useful installing a heating element, controlled by a second thermostat. Because of the manual monitoring (twice per day and usually not in week-ends and holidays) most temperatures outside the specified range are not detected. That means that most of the vaccines that should be discarded are not being discarded, that means a possibility of administration of ineffective vaccines. I have seen lots and lots of cold rooms and freezer rooms without continuous monitoring or alarm systems, that means a possibility administration of ineffective vaccines to regions, districts and PHC level where there is a lot of freezing in ILRs and cold boxes Taking the cost of vaccines and the risk of administration of ineffective vaccines into consideration, it is a must that an effective monitoring system and equipment that is able to maintain the correct temperature be introduced.
