1. Transport of equipment containing ammable refrigerants - See transport regulations
2. Marking of equipment using signs - See local regulations
3. Disposal of equipment using ammable 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
i Checks to the area
Prior to beginning work on systems containing ammable 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.
ii Work procedure
Work shall be undertaken under a controlled procedure so as to minimise the risk of a ammable gas or vapour
being present while the work is being performed.
iii 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 conned 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 ammable material.
iv 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 ammable atmospheres. Ensure that the leak detection equipment being used is
suitable for use with ammable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.
v Presence of re extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate re
extinguishing equipment shall be available to hand. Have a dry powder or CO2 re extinguisher adjacent to the
charging area.
vi 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 ammable refrigerant shall use any sources of ignition in such a manner that it may lead
to the risk of re or explosion. All possible ignition sources, including cigarette smoking, should be kept sufciently
far away from the site of installation, repairing, removing and disposal, during which ammable 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 ammable hazards or ignition risks. No Smoking signs shall be displayed.
vii Ventilated area
Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or
conducting any hot work. A degree of ventilation shall continue during the period that the work is carried
out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the
atmosphere.
