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.
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 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 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 CO2 fire 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.
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 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.
7.Repairs to sealed components
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.
8.Repair to intrinsically safe components
Do not apply any permanent inductive or capacitance loads to the circuit without e
nsuring 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.
07
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.
10.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.
11.Leak detection methods
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.
Oxygen free nitrogen (OFN) shall then be purged through the system both before
and during the brazing process.
12.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.
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.
08
14.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 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 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.
