No ignition sources
No person carrying out work in relation to a REFRIGERATING SYSTEM which
involves exposing any pipe work 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 refrigerant can possibly
be released to the surrounding space.
P.07
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.
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 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:
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.
Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety checks
and component inspection procedures.
P.08
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 no live electrical components and wiring are exposed while charging,
•
recovering or purging the system;
That there is continuity of earth bonding.•
Repairs to sealed components
Ⅰ. 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.
Ⅱ. Sealed electrical components shall be replaced.
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 must be replaced.
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 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.
P.09
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.
The following leak detection methods are deemed acceptable for all refrigerant
systems. Electronic leak detectors may be used to detect refrigerant leaks but, in
the case of FLAMMABLE REFRIGERANTS, 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 also 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.
Removal and evacuation
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;
–
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 .–
P.10
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.
The outlet for the vacuum pump shall not be close to any potential ignition
sources, and ventilation shall be available.
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 in an appropriate position according to the instructions.
•
Ensure that the REFRIGERATING 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 REFRIGERATING SYSTEM. •
Prior to recharging the system, it shall be pressure-tested with the appropriate
purging gas. 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.
P.11
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 recovered 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 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 REFRIGERATING
SYSTEM unless it has been cleaned and checked.
Labelling
Equipment shall be labelled stating that it has been de-commissioned and
emptied of refrigerant.
The label shall be dated and signed. For appliances containing FLAMMABLE
REFRIGERANTS, 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.
P.12
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
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.
