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 refrig-
erant charge. The maximum number of pieces of equipment permitted to be
stored together will be determined by local regulations.
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 minimised. For repair
to the refrigerating system, the following precautions shall be complied with
prior to conducting work on the system.
2)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 per-
formed.
3)General work area
All maintenance sta 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 of. Ensure that the condi-
tions within 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 associ-
ated parts, appropriate fire extinguishing equipment shall be available to hand.
Have a dry powder or CO2 fire extinguisher adjacent to the charging area.
