Ir K T Leung has over 36 years' experience in fire engineering and fire safety management field. He is now a registered professional engineer in fire discipline Hong Kong with fellowship of Institution of Fire Engineers. He is not only a Chartered Fire Engineer, but also holds Chartered qualification in Safety and Health, Environmental Engineering, Energy Engineering, Gas Engineering, Petroleum Engineering and Building Services Engineering. He was a fire officer of HKFSD and served in New Projects Division, Regional Office and Dangerous Goods Licensing. He took part in processing fire safety design of numerous mega projects and fire investigation of major fires. He was also the Head – Corporate Risk Management of the Hong Kong and China Gas Company Limited. Currently, he is the Technical Director of Chem Tech Fire Consultants and focuses on fire engineering and risk consultancy services. He has intensive knowledge and experience on passive fire protection and fire resisting construction. He is now the President of Passive Fire Protection Research Centre and the Chairman of the Product Conformity Certification Scheme for Passive Fire Production Products Task Group under the Joint Technical Committee.
Fire resisting coating system has been applied for passive fire protection for quite a long time. However, its application is limited to steel only. Under the development of advanced technology, the new intumescent fire resisting coating system has widely extended its application to timber, fibre glass, plastic, cement, aluminum, glass, load bearing timber floor and staircase. It is far more than a fire retardant paint. It has been tested to BS476 Part 20, 21 and 22 as well as EN 1363-1, 1364-1, 1365-2 and 1365-6 for 30 minutes, 60 minutes and 90 minutes stability, integrity and insulation. It is foreseeable that it will be further developed to achieve the fire resisting rating of 120 minutes in near future. It does not only provide fire resisting performance but also eliminate all the fire loads of combustible contents to ZERO, which is the key problem in handling performance based fire engineering design of the old timber structures of heritage building and those premises over 50 years under Fire Safety Ordinance Chapter 502 and 572. It also significantly reduces the dead load of fire resisting structures in buildings, which is another key problem on enhancement of fire safety measures of old buildings. The new development in light weight fire and smoke curtains and other intumescent fire resisting products can achieve fire resisting rating of 60 minutes, 120 minutes and up to 240 minutes. They also provide wide range of selections in light weight passive fire protection. Nowadays, there are imminent needs for the building industry, building authority , fire authority, architects and fire engineers in Hong Kong to update their advanced technology in passive fire protection.
In this talk, Ir Leung will cover the following areas of advanced technology of passive fire protection.
1. The new development of technologies and products of passive fire protection in Europe which is considered to be suitable and applicable to Hong Kong construction industry.
2. The current problems with application of advanced technologies and new products in passive fire protection.
3. Cost effectiveness of applying advanced technology of passive fire production products.
