• 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 so
corroded.
• 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 no live electrical components and wiring are
exposed while charging, recovering or purging the system; That there is continuity
of earth bonding.
• Repairs to sealed components
During repairs to sealed components, all electrical supplies shall be disconnected
from the equipment being worked upon prior to any removal of sealed covers,
etc. If it is absolutely necessary to have an electrical supply to equipment during
servicing, then a permanently operating form of leak detection shall be located at
the most critical point to warn of a potentially hazardous situation.
Particular attention shall be paid to the following to ensure that by working on
electrical components, the casing is not altered in such a way that the level of
protection is aected. This shall include damage to cables, excessive number
of connections, terminals not made to original specification, damage to seals,
incorrect fitting of glands, etc. Ensure that apparatus is mounted securely. Ensure
that seals or sealing materials have not degraded such that they no longer serve
the purpose of preventing the ingress of flammable atmospheres. Replacement
parts shall be in accordance with the manufacturer’s specifications.
NOTE: The use of silicon sealant may inhibit the eectiveness of some types of leak
detection equipment. Intrinsically safe components do not have to be isolated prior
to working on them.
