Safety Precautions 2
2. Information servicing(For flammable materials)
2.1 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.
2.2 Work procedure
· Work shall be undertaken under a controlled procedure so as to minimise the
risk of a flammable gas or vapour being present while the work is being
performed.
2.3 Work procedure
· 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 work space
shall be sectioned off.
Ensure that the conditions within the area have been made safe by control of
flammable material.
2.4 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. no sparking, adequately sealed or intrinsically
safe.
2.5 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.
· 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.
2.7 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.
2.8 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.
2.6 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.
2.9 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:
Safety Precautions 3
· 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.
2.10 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. 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.
2.11 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.
2.12 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.
2.13 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.
2.14 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 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 or 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 systemremote from the leak. Oxygen free nitrogen
(OFN) shall then be purged through the system both before and during the
brazing process.
2.15 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.
Safety Precautions 4
· 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.
2.16 Charging procedures
· In addition to conventional charging procedures, the following requirements
shall be followed:
· Ensure that contamination of different refrigerants does not occur when
using charging equipment. Hoses or lines shall be as short as possible to
minimize the amount of refrigerant contained in them.
· Cylinders shall be kept upright.
· Ensure that the refrigeration system is earthed prior to charging the system
with refrigerant.
· Label the system when charging is complete (if not already).
· Extreme care shall be taken not to overfill the 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.
2.17 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.
· Become familiar with the equipment and its operation.
· Isolate system electrically.
· Before attempting the procedure ensure that:
· mechanical handling equipment is available, if required, for handling
refrigerant cylinders;
· all personal protective equipment is available and being used correctly;
· the recovery process is supervised at all times by a competent person;
· recovery equipment and cylinders conform to the appropriate standards.
· Pump down refrigerant system, if possible.
· If a vacuum is not possible, make a manifold so that refrigerant can be
removed from various parts of the system.
· Make sure that cylinder is situated on the scales before recovery takes
place.
· Start the recovery machine and operate in accordance with manufacturer’s
instructions.
· Do not overfill cylinders. (No more than 80 % volume liquid charge).
· Do not exceed the maximum working pressure of the cylinder, even
temporarily.
· When the cylinders have been filled correctly and the process completed,
make sure that the cylinders and the equipment are removed from site promptly
and all isolation valves on the equipment are closed off.
· Recovered refrigerant shall not be charged into another refrigeration system
unless it has been cleaned and checked.
2.18 Labelling
· Equipment shall be labelled stating that it has been decommissioned and
emptied of
· refrigerant. The label shall be dated and signed. Ensure that there are
labels on the equipment stating the equipment contains flammable refrigerant.
2.19 Recovery
· When removing refrigerant from a system, either for servicing or
decommissioning, it is recommended good practice that all refrigerants are
removed safely.
· When transferring refrigerant into cylinders, ensure that only appropriate
refrigerant recovery cylinders are employed. Ensure that the correct numbers
of cylinders for holding the total system charge are available. All cylinders
to be used are designated for the recovered refrigerant and labelled for that
refrigerant (i.e. special cylinders for the recovery of refrigerant).
Cylinders shall be complete with pressure relief valve and associated shut-off
valves in good working order.
Safety Precautions 5
· Empty recovery cylinders are evacuated and, if possible, cooled before
recovery occurs.
· The recovery equipment shall be in good working order with a set of
instructions concerning the equipment that is at hand and shall be suitable
for the recovery of flammable refrigerants. In addition, a set of calibrated
weighing scales shall be available and in good working order.
· Hoses shall be complete with leak-free disconnect couplings and in good
condition. Before using the recovery machine, check that it is in satisfactory
working order, has been properly maintained and that any associated electrical
components are sealed to prevent ignition in the event of a refrigerant
release. Consult manufacturer if in doubt.
· The recovered refrigerant shall be returned to the refrigerant supplier in
the correct recovery cylinder, and the relevant Waste Transfer Note arranged.
Do not mix refrigerants in recovery units and especially not in cylinders.
· If compressors or compressor oils are to be removed, ensure that they have
been evacuated to an acceptable level to make certain that flammable
refrigerant does not remain within the lubricant. The evacuation process shall
be carried out prior to returning the compressor to the suppliers. Only
electric heating to the compressor body shall be employed to accelerate this
process. When oil is drained from a system, it shall be carried out safely.
