Report on technical seminar of electrical energy isolation through Lockout-tagout (LOTO)

By Ir Wallace POON

It was our pleasure to have invited Ir Richard TSE to give a technical seminar on electrical energy isolation through lockout-tagout at CITAC in Kowloon Bay on 10 October 2019. It is a common sense that any industrial machines or equipment has the potentials to cause harm if it is not isolated or operated correctly. Experiences from the accidents, incidents or even near-misses in the industry alerted that the employees or contractors may be suffered from risks while operating heavy machinery and the type of energy in the working environment. The seminar was jointly organised by the CAD, EVD and AMC. Around 20 participants attended this seminar.

After a warm welcome by seminar chairman - Mr C C Tang (Rep from CAD), Ir Richard TSE gave a brief introduction to why lockout-tagout (LOTO) is important to the industry operations. He highlighted that LOTO is a technique used to prevent energy from being released during the servicing of equipment. This is accomplished by placing locks on energy isolation devices prior to starting work. In some articles on the study of injuries, around 80% of incident or accidents were occurred due to the improper electrical isolation of heavy industrial equipment or machines during servicing. Other injuries were caused by the start of the machines accidentally by their co-workers or the stored energy in the machines or batteries, etc.  Ir TSE also indicated that the relationship among the role of authroised employees, affected employees and other employee in LOTO mechanism. He also gave an example on general procedures for LOTO to indicate the major issues related to the risk of improper LOTO. Attendees felt the seminar is fruitful and informative.     

During the end of session, Ir TSE showed a video demonstrated how the LOTO techniques to be considered and implemented in mainland China. Finally, the seminar chairman presented a souvenir to Ir TSE and a photo with the organising parties was taken.
