No Ignition Sources

Avoid ignition sources during work on refrigerating systems to prevent fire or explosion. Keep ignition sources away from installation, repair, removal, and disposal areas. Survey the area for flammable hazards and display "No Smoking" signs.

Ventilated Area

Ensure the work area is open or adequately ventilated before breaking into the system or conducting hot work. Ventilation should continue during work to disperse refrigerant.

Checks to the Refrigerating Equipment

Electrical components must be fit for purpose. Follow manufacturer's maintenance and service guidelines. Checks for FLAMMABLE REFRIGERANTS include: refrigerant charge vs. room size, ventilation machinery operation, indirect circuit checks, legible markings, and component protection against corrosion.

Checks to Electrical Devices

Initial safety checks and component inspections are required for electrical components. If a safety-compromising fault exists, do not connect power until resolved. If operation must continue, use a temporary solution and report it. Initial safety checks include discharging capacitors safely, ensuring no live components are exposed, and checking earth bonding continuity.

Repairs to Sealed Components

Disconnect electrical supplies before working on sealed components. If power is needed, use permanently operating leak detection. Replace sealed electrical components with manufacturer-specified parts.

Repair to Intrinsically Safe Components

Do not apply permanent inductive or capacitance loads exceeding equipment limits. Replace intrinsically safe components with manufacturer-specified parts to prevent refrigerant ignition.

Cabling

Check cabling for wear, corrosion, pressure, vibration, sharp edges, and aging effects.

Detection of Flammable Refrigerants

Do not use potential ignition sources for leak detection. Electronic leak detectors may be used, but sensitivity may need calibration for FLAMMABLE REFRIGERANTS. Ensure detectors are suitable and not ignition sources. Calibrate detectors in a refrigerant-free area. Leak detection equipment should be set to the LFL of the refrigerant. Avoid detergents containing chlorine.

If a leak is suspected, remove naked flames. If a leak requires brazing, recover or isolate refrigerant remotely. Removal and evacuation procedures must be followed.

Removal and Evacuation

Conventional procedures apply for breaking into refrigerant circuits, but best practice is crucial for flammable refrigerants. Procedures include safely removing refrigerant, purging with inert gas (optional for A2L), evacuation (optional for A2L), flushing/purging with inert gas when using flame, and opening the circuit. Recover refrigerant into approved cylinders per local codes. Purge with oxygen-free nitrogen to render the system safe. Repeat if necessary. Do not use compressed air or oxygen for purging. Venting to atmosphere is allowed after purging. Vacuum pump outlets should be away from ignition sources, with ventilation available.

Charging Procedures

Ensure no refrigerant contamination. Use short hoses. Keep cylinders in position. Earth the system before charging. Label the system upon completion. Pressure-test before recharging and leak-test after charging and before commissioning.

Decommissioning

Technicians must be familiar with the equipment. Recover all refrigerants safely. Take oil and refrigerant samples if analysis is needed. Ensure electrical power is available. Familiarize with equipment, isolate electrically, and then proceed with decommissioning.

• Mechanical handling equipment and personal protective equipment should be available and used correctly.
• Recovery process supervised by a competent person.
• Recovery equipment and cylinders must conform to standards.
• Pump down refrigerant system if possible.
• If 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 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 REFRIGERATING SYSTEM unless it has been cleaned and checked.

Labelling

Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. For appliances containing FLAMMABLE REFRIGERANTS, ensure that there are labels on the equipment stating the equipment contains FLAMMABLE REFRIGERANT.

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 is 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. 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 the flammable refrigerant. If in doubt, the manufacturer should be consulted. 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. The recovered refrigerant shall be processed according to local legislation 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 compressor body shall not be heated by an open flame or other ignition sources to accelerate this process. When oil is drained from a system, it shall be carried out safely.
