2.3 Repairs to sealed
components
2.3.1 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.
2.3.2 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, incorrect fitting of glands, etc.
Ensure that the apparatus is mounted securely.
Ensure that seals or sealing materials have
not degraded to the point 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.
C
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.
2.4 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.
2.5 Cabling
Check that cabling will not be subject to wear,
corrosion, excessive pressure, vibration, 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 compressors or fans.
2.6 Detection of flammable
refrigerants
Under no circumstances shall potential sources
of ignition be used in the searching for or
detection of refrigerant leaks. A halide torch (or
any other detector using a naked flame) shall not
be used.
2.7 Leak detection methods
The following leak detection methods are deemed
acceptable for all refrigerant systems.
Electronic leak detectors may be used to detect
refrigerant leaks but, in the case of flammable
refrigerants, the sensitivity may not be adequate,
or may need re-calibration. (Detection equipment
shall be calibrated in a refrigerant-free area.)
