rect 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
- 4 -
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
compressors or fans.
Leak detection methods
Leak detection fluids are suitable for use with most refrigerants but the use of deter-
gents containing chlorine shall be avoided as the chlorine may react with the refrig-
erant and corrode the copper pipe-work.
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.
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-cali-
br
tion. (Detection equipment shall be calibrated in a refrigerant-free area.) Ensure
that the detector is not a potential source of ignition and is suitable for the refrigerant
used. Leak detection equipment shall be set at a percentage of the LFL of the refrig-
erant and shall be calibrated to the refrigerant employed, and the appropriate
percentage of gas (25% maximum) is confirmed.
Leak detection fluids are also suitable for use with most refrigerants but the use of
detergents containing chlorine shall be avoided as the chlorine may react with the
refrigerant and corrode the copper pipe-work.
NOTE: Examples of leak detection fluids are
- bubble method,
- fluorescent method agents.
