2.2.7 Ventilated area
Ensure that the area is in the open or that it is adequately ventilated before breaking into
the system or conducting any hot work. A degree of ventilation shall continue during the
period that the work is carried out. The ventilation should safely disperse any released
refrigerant and preferably expel it externally into the atmosphere.
2.2.8 Checks to the refrigeration equipment
Where electrical components are being changed, they shall be fit for the purpose and
to the correct specification. At all times the manufacturer's maintenance and service
guidelines shall be followed. If in doubt, consult the manufacturer's technical department
for assistance.
The following checks shall be applied to installations using flammable refrigerants:
• The charge size is in accordance with the room size within which the refrigerant
containing parts are installed;
• The ventilation machinery and outlets are operating adequately and are not
obstructed;
• If an indirect refrigerating circuit is being used, the secondary circuit shall be
checked for the presence of refrigerant;
• Marking to the equipment continues to be visible and legible. Markings and signs that
are illegible shall be corrected;
• Refrigeration pipe or components are installed in a position where they are unlikely to
be exposed to any substance which may corrode refrigerant containing components,
unless the components are constructed of materials which are inherently resistant to
being corroded or are suitably protected against being corroded.
2.2.9 Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety checks and
component inspection procedures. If a fault exists that could compromise safety, then
no electrical supply shall be connected to the circuit until it is satisfactorily dealt with.
If the fault cannot be corrected immediately but it is necessary to continue operation,
an adequate temporary solution shall be used. This shall be reported to the owner of the
equipment so all parties are advised.
