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.
Checks to the refrigerating equipment
Where electrical components are being changed, they shall be fit for the purpose and to the
correct specification. At all times, maintenance and service guidelines shall be followed. If in
doubt, consult a professional for assistance.
The following checks shall be applied to installations using flammable refrigerants:
•
The actual refrigerant charge 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.
•
The marking of the equipment continues to be visible and legible. Markings and signs
that are illegible shall be corrected.
•
Refrigerating pipes/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 that are inherently resistant to
being corroded or are suitably protected against being so corroded.
Checks to electrical devices
Repair and maintenance of 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 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.
Initial safety checks shall include:
•
That the capacitor is discharged: this shall be done safely to avoid the possibility of
sparking.
•
That no live electrical components and wiring are exposed while charging, recovering,
or purging the system.
•
That there is continuity of earth bonding.
