POST 00694E : PIS EQUIPMENT PERFORMANCE FEEDBACK
Follow-up on Posts 00670E, 00676E and 00688E

Abdoulaye Djigo (mailto:[email protected]) from Sénégal gives his point of view
on the performance of some refrigerators. The example he gives of a private
fridge highlights, in my opinion, a widespread problem around the world,
the attitude towards public property. We could as well talk about vehicles.
How many old models still roam the roads of the world because they are
private while public ones (governments', etc...) have been scrapped long ago.

In 2002 we had the opportunity to carry out, during a cold chain training
workshop, a control of the working condition of refrigerators SIBIR 170
litres and collect data from head nurses at health centres. There were 186
refrigerators donated by the African Development Bank for a project
covering three regions in Senegal. The refrigerators were installed in
September 2001 and helped to improve immunization coverage in recipient areas.
Generally they worked in a satisfactory manner. Out of the 186
refrigerators, 3 were found defective and replaced by the manufacturer.
During the course of our tours in 2004, five refrigerators were reported to
be out of order. Officials reported excessive cooling for three of these.
Our experience indicates that it is more often the result of poor
operation, leading to thermostat and electrical resistance damage. There is
a real problem of utilization.
In 2002, we came across a nurse who said he had bought a refrigerator
from an expatriate. It was an absorption refrigerator 30 years old at the
time. He had used it for 16 years and sold it still in good working condition.
This shows the reliability of some equipment cannot be questioned. However
operations methods need to be reviewed. Nevertheless, we should not
exonerate so easily the manufacturers as they should always follow-up on
their equipment in order to understand and take into account problems of
premature deterioration of some parts (resistance, thermostat, needle
thermometers, piezoelectric lighting, etc.
