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 minimised. 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 minimise the
risk of a flammable gas or vapour 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 cigarette smoking,
should be kept sufficiently far away from the site of installation, repairing,
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.
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.
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.
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.
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 appliances containing
flammable refrigerants, the system shall be purged with oxygen-free nitrogen
to render the appliance safe for flammable refrigerants. This process might
need to be repeated several times. compressed air or oxygen shall not be used
for purging refrigerant systems.
For appliances 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.
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 minimise 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.
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.
Equipment shall be labelled 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.
