1. Service information
1.1 Area verification
Before starting work on systems containing flammable refrigerants, safety checks are
necessary to ensure that the risk of ignition is minimised. Before repairing the cooling system,
the following precautions must be observed:
1.2. Work procedure
The work must be carried out in accordance with a controlled procedure to minimise the risk of
a flammable vapour or gas being present while the work is being carried out.
1.3. General workspace
All maintenance personnel and others working in the area should be briefed on the nature
of the work to be carried out. Work in confined spaces must be avoided. The area around the
workspace should be divided into sections. Ensure that conditions within the workspace are
safe by keeping flammable material under control.
1.4. Refrigerant verification
The area should be checked with an appropriate refrigerant detector before and during
work to ensure that the technician is warned of potentially flammable atmospheres. Ensure
that the leak-detection equipment used is suitable for use with flammable refrigerants, i.e.,
non-sparking, adequately sealed, or intrinsically safe.
1.5. Presence of fire extinguishers
If any high-temperature work is to be carried out on the refrigeration equipment or any
associated parts, suitable extinguishing equipment must be available. Always have a
dry-powder or CO2 fire extinguisher nearby the load area.

1.6. Absence of ignition sources
No person carrying out work related to a refrigeration system involving the exposure of piping
containing or having contained flammable refrigerant should use any source of ignition in
such a manner as to create a risk of fire or explosion. All possible sources of ignition, including
cigarette smoking, should be kept far enough away from the installation, repair, pick-up, and
disposal site, where flammable refrigerant can be released into the surrounding space. Before
work starts, the area around the equipment must be thoroughly examined to ensure that no
danger or risk of ignition is present. "No Smoking" signs must be displayed.
1.7. Ventilation
Ensure that the area is outdoors or adequately ventilated before intervening in the system
or carrying out any work at high temperature. Proper ventilation must be kept at all times
during work. Ventilation should safely disperse any refrigerant released and preferably expel
it externally to the atmosphere.
1.8. Verification of refrigeration equipment
When electrical components are replaced, they must be fit for purpose and to the correct
specification. The manufacturer's maintenance and service guidelines must be followed at all
times. In case of doubt, refer to the manufacturer's technical department for assistance.
The following checks must be applied to installations using flammable refrigerants:
- The charge size is in accordance with the size of the room within which the refrigerant
containing parts are installed.
- Ventilation machinery and outlets are properly operated and unobstructed.
- If an indirect cooling circuit is used, the secondary circuit must be checked for the presence
of refrigerant.
- Equipment marking remains visible and legible. Markings and symbols that are illegible
should be corrected.
- The components or refrigerant piping are installed in a location where they are not
susceptible to exposure to any substance that may corrode the refrigerant containing
components, unless the components are constructed of materials that are inherently
corrosion resistant or are adequately protected against corrosion.
1.9. Verification of electrical devices
Repair and maintenance of electrical components should include initial safety checks and
component-inspection procedures. If there is a fault that may compromise safety, then no
power supply should be connected to the circuit until the fault is satisfactorily dealt with. If
the fault cannot be corrected immediately, but continued operation is necessary, a suitable
temporary solution must be used. This should be reported to the owner of the equipment so
as to inform all parties.
During initial safety checks, make sure
- that capacitors are unloaded–this must be done in a safe manner to avoid sparks;
