6 Safety 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 should be connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used, but this must be reported to the owner of the equipment so all parties are aware. Initial safety checks should be as follows: • Ensure that capacitors are discharged. This should be done in a safe manner to avoid the possibility of sparking. • Do not work on “live” electrical components and wiring whilst charging, recovering or purging the system. • Continuity of earth bonding. During repairs to sealed components, all electrical supplies must 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 forewarn the individual of a potentially hazardous situation. For repairs to sealed components, particular attention should be paid to the following: • Ensure that by working on electrical components, the casing is not altered in such a way that the level of protection is affected. This should include damage to cables, too many connections, terminals not made to the original specification, damage to seals, incorrect fitting of glands, etc. This includes the secure mounting of the apparatus. • Ensure that seals or sealing materials have not degraded such that it is no longer serving the purpose of preventing the ingress of flammable atmospheres. • Replace only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak. Check that cabling will not be subject to wear corrosion, excessive pressure, sharp edges or any other adverse environmental effects. This should also take into account the effects of ageing or continual vibration from sources such as the compressor or fans. Detection of hydrocarbon refrigerants Under no circumstances should potential sources of ignition be used in the searching or detection of refrigerant leaks. A halide torch (or any other detector using a naked flame) must not be used. The following leak detection methods can be used on systems containing hydrocarbons: • Electronic leak detectors may be used to detect hydrocarbons, but the sensitivity may not be adequate, or may need calibration (detection equipment should be calibrated in a refrigerant- free area). Ensure that the detector is not a potential source of ignition and is suitable for hydrocarbon refrigerants. 134 Safe Refrigerant HandlingPDF Image | Manual for Refrigeration Servicing Technicians
