If it is 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.
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 live in
the presence of a flammable atmosphere. The test apparatus shall be at the correct
rating.
- 8 -
CAUTION
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 consider 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 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.
- 9 -
CAUTION
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 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 minimize 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.

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.
- 11 -
CAUTION
