COMPETENCE OF SERVICE PERSONNEL
General
• Procedural information additional to standard information regarding
refrigeration appliance installation, repair, maintenance, and decommission
procedures is required when an appliance with flammable refrigerants is in
question.
• Training for these procedures is carried out by national training
organizations and manufacturers that are accredited to teach relevant
national competency standards.
• The achieved competence should be documented by a certificate.
Training
Training should include the following:
• Information about the explosion potential of flammable refrigerants to show
that flammable substances may be dangerous when handled without care.
• Information about potential ignition sources, especially those that are not
obvious, such as light switches, vacuum cleaners, or electric heaters.
Information about various safety concepts:
• In the case of unventilated enclosure– (see Clause GG.2) Safety of the
appliance does not depend on ventilation of the appliance housing.
Switching off the appliance and opening the housing has no significant effect
on the safety. Nevertheless, it is possible that leaking refrigerant could
accumulate inside the enclosure and that flammable refrigerant could be
released when the housing is opened.
• In the case of ventilated enclosure – (see Clause GG.4) Safety of the
appliance depends on ventilation of the housing. Switching off the appliance
and/or opening the enclosure has a significant effect on safety. Care should
be taken to ensure sufficient ventilation before housing is opened.
• Ventilated room – (see Clause GG.5) Safety of the appliance depends on the
ventilation of the room. Switching off the appliance or opening the housing
has no significant effect on the safety. The ventilation of the room should
not be shut off during repair procedures.
• Information about the concept of sealed components and sealed enclosures
according to IEC 60079-15:2010.
