1. Transport of equipment containing flammable refrigerants
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 equipment should be in accordance with the manufacturer's instructions.
5. Storage of packed (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.
6. Information on servicing
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 minimised. For repair to the refrigerating system, the
following precautions shall be complied with prior to conducting work on the system.
1) 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) 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 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.
4) 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 CO
2
fire
extinguisher adjacent to the charging area.
5) No ignition sources
No person carrying out work in relation to a refrigeration system which involves exposing any
