WARNINGS (R290/R32 REFRIGERANT ONLY)
1. Transport of equipment containing flammable refrigerants
See transport regulations.
6. Information on servicing
1. Checks to the area
Prior to beginning work on systems containing flammable refrig-
erants, safety checks are necessary to ensure that the risk of igni-
tion is minimized. For repair to the refrigerating system, the fol-
lowing 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
minimize the risk of a flammable gas or vapor 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 work space
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 detec-
tor prior to and during work, to ensure the technician is aware of
potentially flammable atmospheres. Ensure that the leak detec-
tion equipment being used is suitable for use with flammable re-
frigerants, 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 equip-
ment 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.
5. Storage of packed (unsold) equipment
Storage package protection should be constructed such that me-
chanical 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 de-
termined by local regulations.
4. Storage of equipment/appliances
The storage of equipment should be in accordance with the
manufacturer's instructions.
3. Disposal of equipment using flammable refrigerants
See national regulations.
2. Marking of equipment using signs.
See local regulations.
