1) Checks to the area
Prior to beginning work on systems containing flammable refrigerants, safety checks
are necessary to ensure that the risk of ignition is minimized. For repair to the
refrigerating system, the following precautions shall be complied with prior to
conducting work on the system.
2) Work procedure
Work shall be undertaken under a controlled procedure so as to minimize the risk of
a flammable gas or vapor being present while the work is being performed.
3) General work area
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.
The area around the workspace shall be sectioned off. Ensure that the conditions
within the area have been made safe by control of flammable material.
4) Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerating detector prior to and
during work, to ensure the technician is aware of potentially flammable atmospheres.
Ensure that the leak detection equipment being used is suitable for use with
flammable refrigerants. (i.e. non-sparking, adequately sealed or intrinsically safe)
5) Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated
parts, appropriate fire extinguishing equipment shall be available to hand. Have a
dry powder or CO
2 fire extinguisher adjacent to the charging area.
6) No ignition sources
No person carrying out work in relation to a refrigerating system which involves
exposing any pipe work that contains or has contained flammable refrigerant 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 smoking, should be kept sufficiently
far away from the site of installation, repairing, removing and disposal, during which
flammable refrigerant can possibly be released to the surrounding space. Prior to
work taking place, the area around the equipment is to be surveyed to make sure
that there are no flammable hazards or ignition risks. "No Smoking" signs shall be
displayed.
6. Information on servicing
See transport regulations.
1. Transport of equipment containing flammable refrigerants
See local regulations.
2. Marking of equipment using signs
See national regulations.
3. Disposal of equipment using flammable refrigerants
4. Storage of equipment
Storage package protection should be constructed such that mechanical
damage to the equipment inside the package will not cause a leak of the
refrigerant charge. The maximum number of pieces of equipment permitted to
be stored together will be determined by local regulations.
5. Storage of packed (unsold) equipment
The storage of the unit should be in accordance with the applicable regulations
or instructions, whichever is more stringent.
07
7) Ventilated area
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 preferably expel it externally into the atmosphere.
8) Checks to the refrigerating equipment
Where electrical components are being changed, they shall be fit for the purpose
and to the correct specifications. At all times the manufacturer's maintenance and
service guidelines shall be followed. If in doubt consult the manufacturer's technical
department for assistance. The following checks shall be applied to installations
using flammable refrigerants: the actual refrigerant charge is in accordance with the
room size within which the refrigerant containing parts are installed; the ventilation
machinery and outlets are operating adequately and are not obstructed; if an
indirect refrigerating circuit is being used, the secondary circuit shall be checked for
the presence of refrigerant; marking to the equipment continues to be visible and
legible.
Markings and signs that are illegible shall be corrected; and refrigerating pipe or
components are installed in a position where they are unlikely to be exposed to
any substance which may corrode refrigerant containing components, unless the
components are constructed of materials which are inherently resistant to being
corroded or are suitably protected against being so corroded.
9) Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety checks
and component inspection procedures. If a fault exists that could compromise safety,
then no electrical supply shall be connected to the circuit until it is satisfactorily dealt
with. If the fault cannot be corrected immediately but it is necessary to continue
operation, an adequate temporary solution shall be used.
This shall be reported to the owner of the equipment so all parties are advised.
Initial safety checks shall include: That capacitors are discharged: this shall be done
in a safe manner to avoid possibility of sparking; that there no live electrical
components and wiring are exposed while charging, recovering or purging the
system; that there is continuity of earth bonding.
7. Sealed electrical components shall be replaced.
8. Intrinsically safe components must be replaced.
Check that cabling will not be subject to wear, corrosion, excessive pressure,
vibration, sharp edges or any other adverse environmental effects. The check shall
also take into account the effects of aging or continual vibration from sources such
as compressors or fans.
9. Cabling
08
When breaking into the refrigerant circuit to make repairs—or for any other
purpose - conventional procedures shall be used. However, for flammable
refrigerants it is important that best practice be followed, since flammability is
a consideration. The following procedure shall be adhered to:
-Safely remove refrigerant following local and national regulations;
-Evacuate;
-Purge the circuit with inert gas (optional for A2L);
-Evacuate (optional for A2L);
-Continuously flush or purge with inert gas when using flame to open circuit; and
-Open the circuit.
The refrigerant charge shall be recovered into the correct recovery cylinders if
venting is not allowed by local and national codes. For units containing flammable
refrigerants, the system shall be purged with oxygen-free nitrogen to render the
appliance safe for flammable refrigerants. This process may need to be repeated
several times. Do not use compressed air or oxygen to purge refrigerant systems.
For units containing flammable refrigerants, refrigerants purging shall be
achieved by breaking the vacuum in the system with oxygen-free nitrogen and
continuing to fill until the working pressure is achieved, then venting to
atmosphere, and finally pulling down to a vacuum (optional for A2L).
This process shall be repeated until no refrigerant is within the system (optional
for A2L). When the final oxygen-free nitrogen charge is used. the system shall be
vented down to atmospheric pressure to enable work to take place. The outlet
for the vacuum pump shall not be close to any potential ignition sources, and
ventilation shall be available.
11. Removal and evacuation
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.
The following leak detection methods are deemed acceptable for systems
containing flammable refrigerants. Electronic leak detectors shall be used to detect
flammable refrigerants, but the sensitivity may not be adequate, or may need
re-calibration. (Detection equipment shall be calibrated in a refrigerant-free area.)
Ensure that the detector is not a potential source of ignition and is suitable for the
refrigerant used. Leak detection equipment shall be set at a percentage of the LFL
of the refrigerant and shall be calibrated to the refrigerant employed and the
appropriate percentage of gas (25 % maximum) is confirmed. Leak detection fluids
are suitable for use with most refrigerants but the use of detergents containing
chlorine shall be avoided as the chlorine may react with the refrigerant and corrode
the copper pipe-work. If a leak is suspected, all naked flames shall be removed/
extinguished. If a leakage of refrigerant is found which requires brazing, all of the
refrigerant shall be recovered from the system, or isolated (by means of shut off
valves) in a part of the system remote from the leak. Removal of refrigerant shall
be according to Removal and evacuation.
10. Detection of flammable refrigerants
09
Before carrying out this procedure, it is essential that the technician is completely
familiar with the equipment and all its detail. It is recommended good practice
that all refrigerants 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 reclaimed refrigerant. It is essential
that electrical power is available before the task is commenced.
a) Become familiar with the equipment and its operation.
b) Isolate system electrically.
c) Before attempting the procedure ensure that: Mechanical handling equipment
is available, if required, for handling refrigerant cylinders; all personal protective
equipment is available and being used correctly; the recovery process is
supervised at all times by a competent person; recovery equipment and
cylinders conform to the appropriate standards.
d) Pump down refrigerant system, if possible.
e) If a vacuum is not possible, make a manifold so that refrigerant can be
removed from various parts of the system.
f) Make sure that cylinder is situated on the scales before recovery takes place.
g) Start the recovery machine and operate in accordance with manufacturer's
instructions.
h) Do not overfill cylinders. (No more than 80 % volume liquid charge).
i) Do not exceed the maximum working pressure of the cylinder, even temporarily.
j) When the cylinders have been filled correctly and the process completed, make
sure that the cylinders and the equipment are removed from site promptly and
all isolation valves on the equipment are closed off.
k) Recovered refrigerant shall not be charged into another refrigeration system
unless it has been cleaned and checked.
In addition to conventional charging procedures, the following requirements shall
be followed.
Ensure that contamination of different refrigerants does not occur when using
charging equipment.
Hoses or lines shall be as short as possible to minimize the amount of refrigerant
contained in them.
Cylinders shall be kept in an appropriate position according to the instructions.
Ensure that the refrigeration system is earthed prior to charging the system with
refrigerant. Label the system when charging is complete (if not already). Extreme
care shall be taken not to overfill the refrigeration system. Prior to recharging the
system it shall be pressure tested with OFN. The system shall be leak tested on
completion of charging but prior to commissioning. A follow up leak test shall be
carried out prior to leaving the site.
12. Charging procedures
13. Decommissioning
Equipment shall be labeled stating that it has been de-commissioned 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.

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
the flammable refrigerant. If in doubt, the manufacturer should be consulted. 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.
The recovered refrigerant shall be processed according to local legislation in the
correct recovery cylinder, and the relevant waste transfer note arranged. Do not
mix refrigerants in recovery units and especially not in cylinders. If compressors or
compressor oils are to be removed, ensure that they have been evacuated to an
acceptable level to make certain that flammable refrigerant does not remain within
the lubricant. The compressor body shall not be heated by an open flame or other
ignition sources to accelerate this process. When oil is drained from a system, it
shall be carried out safely.
