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 explosion. All possible ignition sources, including cigarette smoking, should be kept
sufficiently far away from the site of installation, repairing, removing and disposal, during which flammable
refrigerant can possibly be released to the surrounding space. Prior to work taking place, the area around the
equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. No Smoking
signs shall be displayed.
