1. Checks to the area
   Prior to beginning work on systems containing flammable refrigerants, safety checks are neces-sary to ensure that the risk of ignition is minimized for repair to the refrigerating system, the following precautions shall be complied with prior to con-ducting work on the system.
   Work procedure
   Work shall be undertaken under a controlled pro-cedure so as to minimize the risk of a flammable gas or vapour being present while the work is being performed.

2.  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.

3.  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 flam-mable atmospheres. Ensure that the leak detection equipment being used is suitable for use with flam-mable refrigerant, i.e. non sparking, adequately sealed or intrinsically safe.

4. Presence of fire extinguisher
   If any hot work is to be conducted on the refrigera-tion equipment or any associated parts, appropri-ate fire extinguishing equipment shall be available to hand. Have a dry powder or CO2 fire extinguish-er adjacent to the charging area.

5.  No ignition sources
   No person carrying out work in relation to a refrig-erant 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, remov-ing and disposal, during which flammable refrig-erant 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.  Ventilated area
   Ensure that the area is in the open or that it is ade-quately ventilated before breaking into the system or conducting any hot wok. 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.

7.  Checks to the refrigeration equipment
   Where electrical components are being changed, they shall be fit for the purpose and to the correct specifi-cation. 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:

8.  the charge size in accordance with the room size within which the refrigerant containing parts are installed;

9.  the ventilation machinery and outlets are operating adequately and are not obstructed

10. Checks to electrical devices
    Repair and maintenance to electrical components shall include initial safety checks and components inspec-tion 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:

11. that capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;

12. that there no live electrical components and wiring are exposed while charging, recovering or purging the system;

13.  that there is continuity of earth bonding

14. 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 pro-tection 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 de-graded such that they no longer serve the purpose of preventing the ingress of flammable atmos-pheres, 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.

15. . Repair to intrinsically safe components Do not apply any permanent inductive or capaci-tance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted for the equipment in use.
    Intrinsically 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 manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.

16. . 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.

17. . Leakage detection for 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.

18. . Leak detection methods
    The following leak detection methods are accept-able for systems containing flammable refrigerant. Electronic leak detectors shall be used to detect flammable refrigerants, but the sensitivity may not be adequate, or may need recalibration (Detection equipment shall be calibrated in a refrigerant-free area.) Ensure that detector is not a potential source of ignition and is suitable for the refrigerant used.
    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 leak of refrigerant is found which requires braz-ing, all of the refrigerant shall be recovered from the system. Oxygen free nitrogen (OFN) shall then be purged through the system both before and during the brazing process.

19.  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 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 atmos-pheric pressure to enable work to take place.
    This operation is absolutely vital if brazing operations on the pipework are to take place. Ensure that the outlet for the vacuum pump is not close to any igni-tion sources and there is ventilation available.

20.  Refrigerant Charging procedures.
    In addition to conventional charging procedures, the following requirements shall be followed.

21.  Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to mini-mize the amount of refrigerant contained in them.

22.  Cylinders shall be kept upright.-

23. Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.

24.  Label the system when charging is complete (if not already).

25.  Extreme care shall be taken not to overfill the refrig-eration 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 commissioning. A follow up leak test shall be carried out prior to leaving the site.

26. Decommissioning

    • Before carrying out this procedure, it is essential that 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 reuse 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: me-chanical handling equipment is available, if repaired, for handling refrigerant cylinders; all personal protec-tive 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 accord-ance 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 an-other refrigeration system unless it has been cleaned and checked.

27.  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 la-bels on the equipment stating the equipment contains flammable refrigerant.

28. 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 number of cylinders for holding the total system charge are available. All cylinders to be used are designed 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 value and associated shut-off values in good working order. 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 equip-ment 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 work 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 main-tained and that any associated electrical compo- nents 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 re-turning 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.

29. Transport of equipment containing flammable refrigerants.
    Determined by local regulations.

30.  Discarded appliances supplies flammable refrigerants.
    See National Regulations.

31.  Storage package (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.
