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 minimized. 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 minimize the risk of a flammable

gas or vapor 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

 Page 6



Safety

Precautions

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

 Page 7

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 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. Replace components only with parts
specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere
from a leak.

Safety

Precautions

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
refrigerant used. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant

shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25 %

maximum) is

the

and

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
