AbstractThere are over 50000 Registered Electrical Workers (REW) in Hong Kong SpecialAdministrative Region (HKSAR). The average number of electrical accidents is 56 casesper annum over the past eight years. Electrocution has been one of the highest fatalaccident rate amongst all industrial mishaps. Uses of insulating gloves are often prescribedafter an electrical accident. In searching the documentation on 402 electrocution cases ofthe National Institute for Occupational Safety and Health of USA (NIOSH), concluded that95 cases could have been prevented with uses of insulating gloves and other personalprotective equipment (PPE).In Hong Kong SAR, the application of insulating gloves has neither been popular in theworkplaces or nor been appropriately placed in the hierarchy of hazard control. Instead ofbeing applied as the last line of defence, the apparent simplicity of insulating gloves wasused in common sense for live working without due electrical risk assessment. Furtherreview on international standards of insulation gloves for live working indicated that thestandards were mainly specification on manufacturing and testing of gloves underlaboratory conditions. There is no official guideline on the selection and use of insulatinggloves in work environments.Given the aforementioned, a study consisted of literature review, pilot interview andquestionnaire survey was conducted on a group of random sampled REW amongst thecontracting branch, servicing branch, power supply companies and trade unions. Salientfindings were:iv
• 90% of the electricians of the surveyed 216 samples had encountered live work and21% did not isolate the power in their daily work.• Inadequate risk assessment and electrical shock hazard elimination procedures in theirroutine jobs.• 81% of the electricians did not wear insulating gloves, with mostly the perception oflost of dexterity and lack of grip.• Incomprehensive knowledge in selection of suitable insulating gloves.• Inadequate training and skill in the use and maintenance of insulating gloves.The findings conclusively confirmed the need of guidelines on selection, and care ofinsulating gloves. Technical guides on the selection, use and maintenance were preparedand recommended for the REW in HKSAR, based on the survey results. For easy referenceof electrical workers in the trade, a draft “Guidance Notes” on the issues was also prepared,as an attachment of the project report.v
