from electricity in work activities. Regulation 14 of EAWR specifies that no person shall beengaged in any work activity on live work that danger may arise unless:• It is unreasonable for it to be dead.• It is reasonable for him to be at work on it live.• Suitable precautions (including where necessary the provision of suitable protectiveequipment) are taken to prevent injury.In Hong Kong, there are no similar safety clauses in our Electricity Ordinance. Isolation ofelectrical equipment is encouraged in the Code of Practice for the Electricity Regulations(1997). It is, however, remarked that where serious inconvenience would arise fromisolating circuits, adequate precautions should be taken to avoid danger for work involvingthe handling of energized parts or working within touchable distance, direct or indirect, ofenergized parts at low voltage. The Code allows live works with the following precautions:• Live works should be done only by Registered Electrical Workers (REW), or under hissupervision.• Screen or other means to avoid danger from inadvertent contact with energizedconductors should be provided.• Fixing of warning notices for repair, barriers and screens.It is, however, according to the Occupational Safety and Health Branch of LabourDepartment (2002), comparatively high percentage of live work were executed withoutproper isolation of electricity source at work, mainly due to the following reasons.• Deliberately not isolating power supply source−Under-estimate the hazards and the consequence of accidents.29
−−Over estimate one’s competency and carefulness at work.Cut comers to save time and for convenience.• No Lock Out Procedure−The isolate power source has not been locked out so that it could be connectedback accidentally.−No warning notice, signs or tags posted at the isolated power source to alertothers not to disturb it.• Deficiency in the working system−Inadequate house rules and working system to govern the isolation of powersupply for electrical work.−Lack of supervision such that workers committed danger acts instead offollowing safety procedures.−Lack of management control on the access of power supply source/electricalswitch room.It would seem “worker behaviour” and “system of work” are the two key issues to beincluded in the survey to help the understanding of the live work practices of REW inexecution of their routine jobs.In Mainland China, 6kV-10kV distribution networks are the most common supplyinfrastructure for industries and households. To ensure supply securities and avoidance ofregional power interruption, the repairs and upkeep of which are frequently executed in live(Wu, 2001). Special trainings are provided to workers by provincial power supply units.According to Wu (2001), the specified conditions for live works are:30
