OR
7. Whenever possible, always use one of the above methods. If this is not
possible, then the following method can be applied. Flame the bases and lids
of the dishes with a lighter or gas burner using the tweezers to hold the bases
and lids. Assemble while still hot.
3.6 Disposal of Contaminated Material
Note: To minimise the risk of infection from contaminated materials, take care not
to touch contaminated membranes directly with your hands. Do not eat, drink or
smoke while handling contaminated materials. Wash your hands immediately after
you have touched any contaminated material and after you have finished your
work.
Contaminated material, such as used membranes and pads, MUST be made safe
before disposal. DO NOT discard non-sterile membranes and pads into the
environment since they pose a major risk to public health.
After you have completed the analysis, stack the petri-dishes in the straps and
sterilise the dishes and contents at 121°C for 30 minutes using an autoclave,
steriliser or pressure cooker. Alternatively, plunge the petridishes, pads and
membranes into boiling water and heat for at least 30 minutes (use a dedicated pan
for this procedure. DO NOT use a pan that will subsequently be used for food
preparation or other domestic purposes). After sterilisation, the used membranes
and pads may be destroyed by incineration.
The petri-dishes must be carefully washed with detergent after use, rinsed with
clean water and dried.
3.7 Absorbent Pads and Dispenser
The pads are supplied sterile in packs of 100 units. A pad dispenser is also supplied
with the kit. Never leave the dispenser without a pack of pads attached as it will
increase the possibility of contamination.
You might find it more convenient to dispense the pads into the petri dishes at your
base to avoid the need to take the dispenser and pads into the field.
If it is necessary to dispense pads in the field, take care not to contaminate the
dispenser assembly. If the dispenser is lost or damaged, pads may be dispensed in
the field using the sterile tweezers (see Section 5.4.4[3] for sterilisation methods).
Some kit operators prefer this method to using the dispenser.
