which are inherently resistant to being corroded or are suitably protected
against being so corroded.
6-9 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
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.
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 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
Safety precautions
8
CAUTION
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.
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;
Safety precautions
9
CAUTION
– 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.
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.
Safety precautions
10
CAUTION
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 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.
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
Safety precautions
11

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.
