Dr Alex Tse, Honorary Advisor of the Institution of Occupational Safety and Health (IOSH) Hong Kong Branch was invited by the CA Division to make a presentation at the captioned webinar on 16 March 2022 from 6:30 pm. Around 200 participants joined in.


Ir Louis Yiu was the Facilitator, Miss Crystal Chan was the MC and Ir Prof Louis Lock, CA Division Past Chairman and the CAI Discipline Advisory Panel (CAI DAP) Chairman delivered the ‘Vote of Thanks’.


First, Dr Tse started by introducing the concept of ‘Ergonomics’. He explained that ergonomics was applied information about human behaviour, abilities and limitations and other characteristics in the design of tools, machines, tasks, jobs, and environments for productive, safe, comfortable, and effective human use.


As the COVID-19 situation has caused an abrupt shift in working practices, many staff have been working from home. With often less than ideal working conditions, this has resulted in a lot of people suffering ergonomic problems such as back, neck, shoulder and upper extremity pain. Dr Tse explained how physical and cognitive ergonomics, and other human factors such as the demands of the work, physical movements and even the overall environment can all affect health and safety. He also mentioned that there were two legislations with ergonomic contexts in Hong Kong.


Dr Tse pointed out that as human beings we are all different in terms of our body structures, and anthropometric data varied in different populations groups. If office furniture and tools do not offer the right comfort level for each individual user, it reduces productivity and causes muscle stress.


This means that factors relating to anthropometry, posture, repetitive motion, and workplace injury should be considered in achieving an ideal ergonomic design. He demonstrated how ergonomic workplaces could be achieved and he elaborated on the health effects of vibration. He also explained the five fundamental fallacies in ergonomics.


Miss Chan moderated the question-and-answer session and Dr Tse responded to participants’ questions. Finally, Miss Chan invited Ir Prof Lock to draw his conclusion and he expressed his eagerness to work with IOSH Hong Kong in the future.

The PM Session of the captioned Summit started in the afternoon of 26 February 2022. MC Miss Crystal Chan gave a brief introduction, after which the Vice President Ir Dr Barry Lee delivered the Keynote Address. The members of the Organising Committee (OC) and the CA Division, and the participants were deeply impressed by our Ir Dr Lee’s message.


Ir Dr Ming Ge, General Manager of The Hong Kong Productivity Council, then gave a presentation on ‘AI-powered Real-time Tunnel Surface Inspection Using Edge Computing and Drones’. He mentioned that this had been developed for efficient and accurate tunnel surface inspection and defect detection. He highlighted that the proposed sensor-fusion method and SAHI-based method could be used to detect small cracks, spalling and leaks in tunnel surface. The methods were successfully applied in the pilot study of the Cha Kwo Ling Tunnel.


Ms Ivy Li, the Founder of Wildfaces Technology Ltd., explained ‘AI for Facility Management’ and demonstrated some successful cases.


Then, Mr Graham Lui of the Electrical and Mechanical Services Department (EMSD) presented a paper ‘Digital Logbooks for Lifts and Escalators’ which concerned many professionals in the control/lift industries. He explained how Digital Logbooks could help professionals accomplish their tasks more efficiently by providing them with instant data, for better communications and work planning. For the EMSD, detailed data and analytical results on lifts and escalators could be used to help set policies for improving lift/escalator safety.


Mr C C Tang, an OC Member then presented souvenirs and appreciation certificates to the Speakers. Ir Prof Eddie Lock, OC Chairman, took care of the question-and-answer session. While Ir Prof The Hon Sun Dong the Division Chairman, and Ir Prof Eddie Lock showed their gratitude to the Division, OC Members and the participants.


During his closing address, Ir Prof Louis Lock conveyed his sincere thanks to the InstMC HK, the Co-Organiser, the sponsors: China Mobile Hong Kong, CLP Power Hong Kong, Schneider Electric Hong Kong and Hongkong Electric; and the supporting organisations: MC and MI Divisions and AMC.
