accumulation of refrigerant leaks resulting in a risk of fire or explosion due to ignition of the refrigerant caused by electric
heaters, stoves, or other sources of ignition.
● The appliance must be stored in such a way as to prevent mechanical failure.
● Individuals who operate or work on the refrigerant circuit must have the appropriate certification issued by an accredited
organization that ensures competence in handling refrigerants according to a specific evaluation recognized by associations in
the industry.
● Repairs must be performed based on the recommendations from the manufacturing company.
● Maintenance and repairs that require the assistance of other qualified personnel must be performed under the supervision of
an individual specified in the use of flammable refrigerants.

● The appliance shall be stored in a room without continuously operating open flames (for example an operating gas appliance)
or other potential ignition sources (for example an operating electric heater, hot surfaces).
● All the work men who are engaging in the refrigeration system should bear the valid certification awarded by the authoritative
organization and the qualification for dealing with the refrigeration system recognized by this industry. If it needs other

● Compliance with national gas regulations shall be observed.
● Keep ventilation openings clear of obstruction.
● The appliance shall be stored so as to prevent mechanical damage from occurring.
● A warning that the appliance shall be stored in a well-ventilated area where the room size corresponds to the room area as
specified for operation.
● Any person who is involved with working on or breaking into a refrigerant circuit should hold a current valid certificate from an
industry-accredited assessment authority, which authorizes their competence to handle refrigerants safely in accordance with
an industry recognized assessment specification.
● Servicing shall only be performed as recommended by the equipment manufacturer.
● Maintenance and repair requiring the assistance of other skilled personnel shall be carried out under the supervision of the
