9.1 Safety of the working environment
9.1.1 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 of the refrigerating system, the following precautions shall be complied with prior to
conducting work on the system.
9.1.2 Work procedure:
W
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.
9.1.3 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 condi-
tions within the area have been made safe by control of flammable material.
9.1.4 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 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.
9.1.5 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 CO2 fire extinguisher adjacent to the charging area.
9.1.6 No ignition sources:
No person carrying out work on a refrigeration system which involves exposing any pipe work that contains or has con
No person carrying out work on a refrigeration system which involves exposing any pipe work that contains or has con-
tained flammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk of fire or explo-
sion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of instal-
lation, 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 flam-
mable hazards or ignition risks. “No Smoking” signs shall be displayed.
9.1.7 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.
9.1.8 Checks to the refrigeration equipment:
Where electrical components are being changed, they shall be fit for the purpose and to the correct specification.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.
The following checks shall be applied to installations using flammable refrigerants:
– The charge size 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.
– Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected.
– Refrigeration 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 in-
herently resistant to being corroded or are suitably protected against being corroded.
9.1.9 Checks to electrical devices:
Repair and maintenance to electrical components shall include initial safety checks and component inspection proce-
dures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is sa-
tisfactorily 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 the possibility of sparking.
• that no live electrical components and wiring are exposed while charging, recovering or purging the system.
• that there is continuity of earth bonding.

9.2 Repairs to sealed components
9.2.1 During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked
upon prior to any removal of sealed covers etc. If it is absolutely necessary to have an electrical supply to equipment
during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of
a potentially hazardous situation.
9.2.2 Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is
9.2.2 Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is
not altered in such a way that the level of protection is affected. This shall include damage to cables, excessive number of
connections, terminals not made to original specification, damage to seals, incorrect fitting of glands etc. Ensure that the
apparatus is mounted securely. Ensure that seals or sealing materials have not degraded such that they no longer serve
the purpose of preventing the ingress of flammable atmospheres. Replacement parts shall be in accordance with the
manufacturer’s specifications.
NOTE:
NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection equipment. Intrinsically
safe components do not have to be isolated prior to working on them.
9.2.3 Repair to intrinsically safe components
Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the per
Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the per-
missible voltage and current permitted for the equipment in use. Intrinsically safe components are the only types that can
be worked on live in the presence of a flammable atmosphere. The test apparatus shall be at the correct rating. Replace
components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the at-
mosphere from a leak.
9.2.4 Cabling
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.
9.2.5 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.
9.2.6. Leak detection methods
The following leak detection methods are deemed acceptable for systems containing flammable refrigerants:
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 (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 bra-
zing, 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. Oxygen free nitrogen (OFN) shall then be purged through the system both before and
during the brazing process.
9.2.7 Removal and evacuation
When breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures shall be
used. However, it is important that best practice is followed since flammability is a consideration. The following procedure
shall be adhered to:
• Remove refrigerant
• Purge the circuit with inert gas
• Evacuate
• Purge again with inert gas
• Open the circuit by cutting or brazing
• Open the circuit by cutting or brazing
The refrigerant charge shall be recovered into the correct recovery cylinders.
The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be “flushed” with OFN to
render the unit safe. This process may need to be repeated several times. Compressed air or oxygen shall not be used
for this task. Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until the
working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum. This process shall be re-
peated until no refrigerant is within the system. When the final OFN charge is used, the system shall be vented down to
atmospheric pressure to enable work to take place.atmospheric pressure to enable work to take place. This operation is absolutely vital if brazing operations on the pipe-
work are to take place. Ensure that the outlet for the vacuum pump is not close to any ignition sources and there is venti-
lation available.

9.2.8 Charging procedures:
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 upright.
– Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.
– Label the system when charging is complete (if not already).
– 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.
9.2.9 Decommissioning:
Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its 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 the system electrically.
c) Before attempting the procedure ensure that:
• Mechanical handling equipment is available, if required, for handling refrigerant cylinders.
• 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 the cylinder is situated on the scales before recovery takes place.
g) Start the recovery machine and operate in accordance with the manufacturer's instructions.
g) Start the recovery machine and operate in accordance with the 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 is completed, make sure that the cylinders and the equip-
ment 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.
9.2.10 Labelling:
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.
9.2.11. Recovery:
When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that
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 availa-
ble. All cylinders to be used are designated for the recovered refrigerant and labelled for that refrigerant (e.g. special cy-
linders 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 the maany associated electrical components are sealed to prevent ignition in the event of a refrigerant release. Consult the ma-
nufacturer if in doubt. The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylin-
der, and the relevant waste transfer note shall be 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 evacuation process shall be car
ried out prior to returning the compressor to the suppliers. Only electric heating to the compressor body shall be emplo-
yed to accelerate this process. When oil is drained from a system, it shall be carried out safely.
