06
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
The storage of equipment should be in accordance with the manufacturer's instructions.
4.Storage of equipment/appliances
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
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 vapour
being present while the work is being performed.
3)General work area
All maintenance staf 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 of.
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.
6.Information on servicing
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;
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.
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.
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, 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
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:
07
08
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
are 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
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 efectiveness of some types of leak detection equipment.
Intrinsically safe components do not have to be isolated prior to working on them.
8.Intrinsically safe components must be replaced
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.
9.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.
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
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 n
flammable refrigerants. This process might 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.
11.Removal and evacuation
09
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. Ensure that the outlet for the
vacuum pump is not close to any potential ignition sources and that ventilation is 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.
12.Charging procedures
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.
13.Decommissioning
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.
10
11
g)Start the recovery machine and operate in accordance with 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.
14.Labelling
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.
15.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 labeled 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.
Non-duct connected appliances containing A2L refrigerants with the supply and return air openings in the
conditioned space may have the body of the appliance installed in open areas such as false ceilings not being
used as return air plenums, as long as the conditioned air does not directly communicate with the air of the false
ceiling.
