WARNINGS (for using R290/R32 refrigerant only)
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 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.
2)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.
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 conned spaces shall be avoided. The area
around the workspace shall be sectioned o. Ensure that the conditions within the area
have been made safe by control of ammable 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 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.
5)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.
6)No ignition sources
No person carrying out work in relatio
n 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 suciently 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.
