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.

i) 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.
23. REPAIRS TO SEALED COMPONENTS
a) 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.
b) 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a󰀨ected.
This shall include damage to cables, excessive number of connections,
terminalsnotmadetooriginalspecication,damagetoseals,incorrecttting
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ammableatmospheres.
Replacement parts shall be in accordance with the manufacturer’s
specications.
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.
24. 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ammable
atmosphere.
The test apparatus shall be at the correct rating.
 Replacecomponentsonlywithpartsspeciedbythemanufacturer.
Other parts may result in the ignition of refrigerant in the atmosphere from a
leak.
25. CABLING
Check that cabling will not be subject to wear, corrosion, excessive pressure,
vibration,sharpedgesoranyotheradverseenvironmentale󰀨ects.
 Thecheckshallalsotakeintoaccountthee󰀨ectsofagingorcontinualvibration
from sources such as compressors or fans.

26. 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ame)shallnotbeused.
27. LEAK DETECTION METHODS
The following leak detection methods are deemed acceptable for systems
containingammablerefrigerants.
 Electronicleakdetectorsshallbeusedtodetectammable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conrmed.
 Leakdetectionuids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ames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o󰀨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.
28. 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ammability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ushed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lluntiltheworkingpressureisachieved,thenventingto
atmosphere,andnallypullingdowntoavacuum.
This process shall be repeated until no refrigerant is within the system. When
thenal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.
