WARNING
!
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.
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.
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.
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.
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.
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.
Page 11
SAFETY INSTRUCTIONS
11
EN
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.
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 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.
- 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 inherently resistant to
being corroded or are suitably protected against being so corroded.
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:
- Capacitors are discharged: this shall be done in a safe manner to avoid possibility of
sparking.
- No live electrical components and wiring are exposed while charging, recovering or
purging the system.
- Continuity of earth bonding.

Repairs to sealed components
• 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.
• 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.
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 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.
Cabling Check
• 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 ageing or continual vibration from sources such as compressors
or fans.
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.
Leak detection methods
• The following leak detection methods are deemed acceptable for systems containing
flammable refrigerants.
Page 13
SAFETY INSTRUCTIONS
13
• 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.
• Oxygen free nitrogen (OFN) shall then be purged through the system both before and
during the brazing process.
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.
• 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.

SAFETY INSTRUCTIONS
14
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.
Decommissioning
• 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 the 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.
Page 15
SAFETY INSTRUCTIONS
15
EN
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.
Labelling
• Equipment shall be labelled stating that it has been decommissioned 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.
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 are 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
