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 preferable expel it externally into the atmosphere.
8. Checks to the refrigeration equipment
Where electrical components are being changed, they shall be fitted 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 ventilator 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.
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. Initial safety checks shall include:
•
That capacitors are discharged: this shall be done in a safe manner to avoid possibility
of sparking.
•
That there are no live electrical components and wiring exposed while charging,
recovering or purging the system.
•
That there is continuity of earth bonding.
