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.
6.Information on servicing
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
1.Transport of equipment containing flammable refrigerants
See transport regulations
2.Marking of equipment using signs
See local regulations
3.Disposal of equipment using flammable refrigerants
See national regulations.
4.Storage of equipment/appliances
The storage of equipment should be in accordance with the manufacturer's instructions.
5.Storage of packed (unsold) 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.
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 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.
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 CO2fire extinguisher
adjacent to the charging area.
6)No ignition sources
No person carrying out work in relation to a refrigeration 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, 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.

Safety Precautions
Page 8 
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.
8)Checks to the refrigeration equipment
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;
Refrigeration pipe or components are installed in a position where they are unlikely to be exposed
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.
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 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: 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)Checks to electrical devices
7.Repairs to sealed components
Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will
not exceed the permissible voltage and current permitted for the equipment in use. Intrinsically safe
components are the only types that can be worked on while 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 atmosphere
from a leak.
8.Repair to intrinsically safe components
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.

Safety Precautions
Page 9 
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.
Oxygen free nitrogen (OFN) shall then be purged through the system both before and during the
brazing process.
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.
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 repeated 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. 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
ventilation available.
10.Detection of 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
11.Leak detection methods
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
12.Removal and evacuation
13.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).
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.
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.

Safety Precautions

cylinders. (No more than 80 % volume liquid charge). i) Do not exceed the maximum working
pressure of thecylinder, 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.
15.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.
16.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. 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 carried out prior to returning the
compressor to the suppliers. Only electric heating to the compressor body shall be employed to
accelerate this process. When oil is drained from a system, it shall be carried out safely.
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.
14.Decommissioning
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
