SAFETY INSTRUCTIONS
released refrigerant and preferably expel it externally into the atmosphere.
6-8 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 so corroded.
6-9 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 satisfactory 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 parts 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.
7. 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 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 coelectrical
components. The casing is not altered in such a way that the level of protection is
affected. 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.
