WARNING
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 steps shall be
completed prior to conducting work on the system.
Work procedure
• Work shall be undertaken under a controlled procedure so as to minimize the risk of a flammable gas or vapour
being present while the work is being performed.
General work area
• All maintenance sta 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.
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 toxic or flammable atmospheres. Ensure that the leak detection equipment being
used is suitable for use with all applicable refrigerants, i.e., non-sparking, adequately sealed, or intrinsically safe.
Presence of fire extinguisher
• If any hot work is to be conducted on the refrigerating equipment or any associated parts, appropriate fire
extinguishing equipment shall be available on hand. A dry chemical or CO2 fire extinguisher should be adjacent to
the charging area.
No ignition sources
• No person carrying out work in relation to a REFRIGERATING SYSTEM which involves exposing any pipe work 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 suciently far away from the site of installation, repairing,
removing and disposal, during which refrigerant can possibly be released to the surrounding space. Prior to work
taking place, the area around the equipment shall be surveyed to make sure that there are no flammable hazards or
ignition risks. “No Smoking” signs shall be displayed.
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.
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:
A. The actual REFRIGERANT CHARGE is in accordance with the room size within which the refrigerant containing
parts are installed,
B. The ventilation machinery and outlets are operating adequately and are not obstructed,
C. If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of
refrigerant,
D. Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be
corrected,
E. 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.
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:
A. That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;
B. That no live electrical components and wiring are exposed while charging, recovering or purging the system;
C. That there is continuity of earth bonding.

WARNING
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 aected. 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 the apparatus is mounted securely.
• Ensure that seals or sealing materials have not degraded to the point 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.
Cabling
• Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges, or any other
adverse environmental eects. The check shall also take into account the eects of aging or continual vibration
from sources such as compressors or fans.
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.
The following leak detection methods are deemed acceptable for all refrigerant systems:
• Electronic leak detectors may be used to detect refrigerant leaks but, in the case of FLAMMABLE
REFRIGERANTS, the sensitivity might not be adequate, or might 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 can 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 o valves) in a part of the system remote from the leak.
