See transport regulations.
2. Marking of equipment using signs
See local regulations.
3. Disposal of equipment using flammable refrigerants
See national regulations.
4. Storage of equipment/appliances
The storage of the unit should be in accordance with the applicable regulations
or instructions, whichever is more stringent.
5. Storage of packed (unsold) equipment
Storage package protection should be constructed such that mechanical damage

6. Information on servicing
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

conducting work on the system.
2) Work procedure
Work shall be undertaken under a controlled procedure so as to minimize the risk
of a flammable gas or vapor being present while the work is being performed.
3) General work area
nature of work being carried out. Work in confined spaces shall be avoided. The
the area have been made safe by control of flammable material.
4) Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerating 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)
5) Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or any
