Other tips

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
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 performed.
3)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.
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 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 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 involves exposing any pipe work that
contains or has contained
flammable refrigerant shall use any sources of ignition in
such a manner that it may lead to the risk of fire or
