are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken
in case analysis is required prior to re-use of recovered refrigerant. It is essential that electrical power
is available before the task commences.
When removing refrigerant from a system, either for servicing or decommissioning, it is
recommended good practice that all refrigerants are removed safely.
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 all appropriate refrigerants
including, when applicable, FLAMMABLE REFRIGERANTS.
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.
Refrigerant class A3 per ANSI/ASHRAE 34
Warning: Risk of fire / flammable materials, taking care to avoid causing a fire by igniting
flammable material.
All maintenance staff and others working in the local area shall be instructed on the nature of
work being carried out. Work in confined spaces shall be avoided.
If any hot work is to be conducted on the refrigerating equipment or any associated parts,
appropriate fire extinguishing equipment shall be available on hand. A dry chemical or CO2 fire
extinguisher should be adjacent to the charging area.
Notice: Any person who is involved with working on or breaking into a refrigerant circuit should
hold a current valid certificate from an industry-accredited assessment authority, which authorizes
their competence to handle refrigerants safely in accordance with an industry recognized assessment
specification.
Notice: Servicing shall only be performed as recommended by the equipment manufacturer.
Maintenance and repair requiring the assistance of other skilled personnel shall be carried out under
the supervision of the person competent in the use of flammable refrigerants.
No person carrying out work in relation to a REFRIGERATING SYSTEM which involves exposing
any pipe work shall use any sources of ignition in such a manner that it may lead to the risk of fire or
explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far
away from the site of installation, repairing, removing and disposal, during which refrigerant can
possibly be released to the surrounding space. Prior to work taking place, the area around the
equipment shall be surveyed to make sure that there are no flammable hazards or ignition risks "No
Smoking" signs shall be displayed.
Checking for presence of refrigerant, the area shall be checked with an appropriate refrigerant
detector prior to and during work, to ensure the technician is aware of potentially toxic or flammable
atmospheres. Ensure that the leak detection equipment being used is suitable for use with all
applicable refrigerants, i.e., non-sparking, adequately sealed, or intrinsically safe.
Ensure that the area is in the open or that it is adequately ventilated before breaking into the
system or conducting any hot work. A degree of ventilation shall continue during the period that the
work is carried out. The ventilation should safely disperse any released refrigerant and
Where electrical components are being changed, they shall be fit for the purpose and to the correct
specification. At all times, the manufacturer's maintenance and service guidelines shall be followed. If
in doubt, consult the manufacturer's technical department for assistance.
Detection of flammable refrigerants: Under no circumstances shall potential sources of ignition
be used in the searching for or detection of refrigerant leaks. A halide torch (or any other detector
using a naked flame) shall not be used.
