2) The appliance shall be stored in a room without continuously operating ignition sources (for
example open flames, an operating gas appliance, or an operating electric heater)
3) Do not pierce or burn.
4) Be aware that refrigerants may not contain an odor.
5) Appliance shall be installed, operated, and stored in a room with a floor area larger than X
m2
6) The installation of pipe-work shall be kept to a minimum of X m2
7) Spaces where refrigerant pipes shall be in compliance with national gas regulations.
8) Servicing shall be performed only as recommended by the manufacturer.
9) The appliance shall be stored in a well-ventilated area where the room size corresponds
to the room area as specified for operation.
10) All working procedures that affect safety means shall only be carried out by competent
persons.
2. Requirement of Flammable Refrigerant
1) Transport of equipment containing flammable refrigerants: Compliance with the transport
regulations
2) Marking of equipment using signs: Compliance with local regulations
3) Disposal of equipment using flammable refrigerants: Compliance with 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 flammable refrigerants, safety checks are
necessary to ensure that the risk of ignition is minimized. 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 minimize the risk of flammable
gas or vapor 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
the 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.
iv. Checking for the 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.
v. 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.
vi. No ignition sources
No person carrying out work in relation to a refrigeration system that involves exposing any
