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
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 re-
pair 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
performed.
3)General work area
All maintenance staff and others working in the local area shall be instruc-
ted 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 flam-
mable material.
4)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 flam-
mable 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
associated parts, appropriate fire extinguishing equipment shall be available
to hand. Have a dry powder or CO2 fire extinguisher adjacent to the charging
area.
6)No ignition sources
No person carrying out work in relation to a refrigeration system which invol-
