SAFETYINSTRUCTIONS
4. The storage of equipment / appliances should be in accordance with the
manufacturer’s instructions.
5. Storage of packed (unsold) equipment Storage package protection should be
constructed such that mechanical damage to the equipment inside the package
will not cause a leak of the refrigerant charge. The maximum number of pieces of
equipment permitted to be stored together will be by local regulations.
6. Information on servicing.
6-1 Checks to the area
Prior to beginning work on system 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.
6-2 Work procedure
Work shall be undertaken under a controlled procedure so as to minimize the risk of
flammable gas or vapour being present while the work is being performed.
6-3 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.
6-4 Checking for presence of refrigerant
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 hte leak detection equipment being used is suitable for use with flammable
refrigerants, i.e. non-sparking adequately sealed or intrinsically safe.
6-5 Presence of fire extinguisher
If any hot work is to be conducted on the refrigerating equipment or any associated
partsappropriate fire extinguishing equipment shall be available to hand. Have a dry
powder or CO2 fire extinguisher adjacent to the charging area.
6-6 No ignition sources
No person carrying out work in relation to a refrigerating 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.
6-7 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.

SAFETYINSTRUCTIONS
6-8 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.
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 satisfactory 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 parts 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 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 coelectrical
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

-10-
SAFETYINSTRUCTIONS
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 whilelive in
the presence of a flammable atmosphere. The test apparatus shall be at the correct rating.
Replace components onlywith parts specified by the manufacturer. Other parts may result
in the ignition of refrigerant 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 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.
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 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 purged with OFN to render the appliance safe for flammable refrigerants. This
process may need to be repeated several times. Compressed air or oxygen shall not be
