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 satisfacto-
rily 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 possi-
bility of sparking;
– that no live electrical components and wiring are exposed while charging, recov-
ering 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 servic-
ing, 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 affected. This shall include damage to cables, excessive number of
connections, terminals not made to original specification, damage to seals, incor-
rect fitting of glands, etc.
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 can inhibit the effectiveness of some types of leak
detection equipment. Intrinsically safe components do not have to be isolated prior
to working on them.
Repair to intrinsically safe components
Do not apply any permanent inductive or capacitance loads to the circuit without
ensuring that this will not exceed the permissible voltage and current permitted for
the equipment in use.
Intrinsically safe components are the only types that can be worked on while live in
the presence of a flammable atmosphere. The test apparatus shall be at the correct
rating.
Replace components only with parts specified by the manufacturer. Other parts
may result in the ignition of refrigerant in the atmosphere from a leak.
Cabling
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibra-
tion, sharp edges or any other adverse environmental effects. The check shall also
take into account the effects of aging or continual vibration from sources such as
