Labelling
Equipment shall be labelled stating that it has been
decommissioned and emptied of refrigerant. The label shall be
dated and signed. Ensure that there are labels on the equipment
stating the equipment contains flammable refrigerant.
Recovery
When removing refrigerant from a system, either for servicing or
decommissioning, it is recommended good practice that all
refrigerants are removed safely.
When transferring refrigerant into cylinders, ensure that only
appropriate refrigerant recovery cylinders are employed. Ensure
that the correct number of cylinders for holding the total system
charge is available. All cylinders to be used are designated for the
recovered refrigerant and labelled for that refrigerant (i.e. special
cylinders for the recovery of refrigerant). Cylinders shall be
complete with pressure relief valve and associated shut-off valves
in good working order. Empty recovery cylinders are evacuated
and, if possible, cooled before recovery occurs.
The recovery equipment shall be in good working order with a set
of instructions concerning the equipment that is at hand and shall
be suitable for the recovery of flammable refrigerants. In addition,
a set of calibrated weighing scales shall be available and in good
working order. Hoses shall be complete with leak free disconnect
couplings and in good condition. Before using the recovery
machine, check that it is in satisfactory working order, has been
properly maintained and that any associated electrical
components are sealed to prevent ignition in the event of a
refrigerant release. Consult manufacturer if in doubt.
The recovered refrigerant shall be returned to the refrigerant
supplier in the correct recovery cylinder, and the relevant Waste
Transfer Note arranged. Do not mix refrigerants in recovery units
and especially not in cylinders.
