3.2 Weekly tasks
(a)
Check the amount of ice forming around the freezer compartment .it is normal
for a little ice to from in the freezer, but if the ice is thicker than 5mm(1/4 inch) then
move the vaccine to another refrigerator or store it in a cold box with ice packs. The
refrigerator must be switched off, and the refrigerator cabinet defrosted.
The proper steps for DEFROSTING THE REFRIGERATOR CABINET are as
follows:
(I) Move the vaccine to another refrigerator or store it in a cold box
With frozen icepacks.
(ii) Switch the refrigerator OFF
(iii) Open the lid/door of the refrigerator and freezer compartment, and
Remove separator if possible.
(iv) As soon as it is possible to remove ice with your fingers, do so. Do not
remove ice with knives or any other sharp objects.
(v) Wipe the freezer compartment dry after all the ice has melted.
(vi) Clean the refrigerator inside with soap and water, and then dry it carefully.
NEVER use scouring powder, steel wool or abrasive cleaners. Remember to clean
the lid/door-sealing gasket and put some talcum powder on it to prevent it sticking to
the doorframe.
(vii)
Switch the refrigerator back ON.
(viii) Wait until the inside temperature in the refrigerator compartment is less than
8
0
C.
(ix) Return the vaccine to the refrigerator and close the door/lid.
If defrosting is necessary every week, the lid is probably not sealing properly. See
CHECKING THE LID OR DOOR SEALING GASKET described later in this section
under Six-Monthly Tasks.
