10.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 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 manufacturer. Other parts
may result in the ignition of refrigerant in the atmosphere from a leak.
11.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.
12.Leakage detection for 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.
13.Leak detection methods
The following leak detection methods are acceptable for systems containing
flammable refrigerant.
Electronic leak detectors shall be used to detect flammable refrigerants, but
the sensitivity may not be adequate, or may need recalibration (Detection
equipment shall be calibrated in a refrigerant-free area.) Ensure that detector
is not a potential source of ignition and is suitable for the refrigerant used.
Leak detection fluids are 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.
If a leak is suspected, all naked flames shall be removed/extinguished.
If a leak of refrigerant is found which requires brazing, all of the refrigerant
