Safety precautions
Precautions for using R32 refrigerant
The basic installation work procedures are the same as the conventional
refrigerant(R22 or R410A). However, pay attention to the following points:
1.Transport of equipment containing flammable refrigerants
Compliance with the transport regulations 2.Marking of equipment using signs
Compliance with local regulations 3.Disposal of equipment using flammable
refrigerants
Compliance with national regulations 4.Storage of equipment/appliances
The storage of equipment 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
determined by local regulations. 6.Information on servicing 6-1 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 minimised.
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 minimise the risk of
flammable gas or vapour being present while the work is being performed.
2
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. 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.
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 the 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
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.
6-6 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.
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
6-8 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. 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 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 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 affected.

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
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;
presence of a flammable atmosphere. The test Purge the circuit with inert gas;
apparatus shall be at the correct rating.
Evacuate;
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 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
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 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 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. 13.Charging procedures In addition to conventional charging
procedures, the following requirements shall

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. b) Isolate system electrically. c) Before attempting the procedure
