-
Particular attention must be paid to the following to ensure that, when working on
electrical components, the housing is not altered in such a way as to affect safety. This
must include damage to cords, an excessive number of connections, terminals not
conforming to the initial specification, damage to seals, incorrect fitting of the stuffing
box, etc.
-
Ensure that the instrumentation is securely mounted.
-
Ensure that seals or sealing materials have not degraded until no longer being useful
to preventing the penetration of flammable atmospheres. Spare parts must be in
accordance with the manufacturer's specifications.
NOTE: the use of silicone sealant may inhibit the effectiveness of some types of leak-
detection equipment. Intrinsically safe components do not have to be isolated before work.
3. Repair of intrinsically safe components
-
Do not apply any permanent inductive or capacitive load to the circuit without ensuring
that it will not exceed the permissible voltage and current rating for the equipment in use.
-
Intrinsically safe components are the only type of components that can be worked on
in a flammable atmosphere. The test instrumentation must have the correct assigned
features.
-
Replace components only with parts specified by the manufacturer. Other parts can
ignite the refrigerant in the atmosphere from a leak.
4. Wiring
Verify that the wiring is not subject to wear, corrosion, excessive pressure, vibration, sharp
edges, or any other environmental effects. The verification should also take into account the
effects of ageing or continuous vibration from sources such as compressors or fans.
5. Detection of flammable refrigerants
Under no circumstances should potential ignition sources be used in the search for or
detection of refrigerant leaks. Do not use a halide lamp or any other detector using a naked
flame.
6. Leak-detection methods
-
The following leak-detection methods are considered acceptable for systems containing
flammable refrigerants.
-
Electronic leak detectors should be used to detect flammable refrigerants, but the
sensitivity may not be adequate, or may need recalibration (the detection equipment
should be calibrated in a refrigerant-free area). Ensure that the detector is not a potential
ignition source and that it is suitable for the refrigerant used. The leak-detection
equipment must be set to a percentage of the lower flammability limit of the refrigerant
and calibrated for the refrigerant used with the appropriate percentage of gas (maximum
25%) confirmed.
