3. 3 2005 Asia-Pacific Conference on Risk Management and Safety  A compliment was sent to the organizer for inclusion in the proceedings.

4. 4 International Symposium, 7 th AOSFST We just finished successfully! We thank you for your support!  Some encouraging information:  450 attendees, where 15 - HKFSD & 31-BDHK.  Participants over the world such as Hong Kong, China, Taiwan, Japan, Korea, Singapore, India, France, US, Canada, UK, Russian, Australia, Netherland.

5. 5 12. Engineering Approach : A Brief Introduction  Construction industry in the Hong Kong Special Administrative Region (HKSAR) is developing rapidly.  There are new design features such as atrium buildings which were built and found in large scale development projects including shopping centres.  Green/Sustainable Buildings with glass façade, super tall buildings are examples.

6. 6 Many highrise buildings packed together EastWeek, 4 August 2004, pp. 76-77

7. 7  Fire safety features must be designed to the satisfaction of the local authorities as it is a key area to be considered seriously.  This topic has drawn public attention as a consequence to serious accidental fires occurred recently.  People started to aware of the hidden problem on fire safety and ask the question: Whether they are sufficiently protected while staying inside a building ?

8. 8 The Big Garley Building Fire 1996 Accidental fire Bus Fire: Burnt completely within 10 minutes  Solar heat cannot enter.  But in an accidental fire, heat generated by the fire would be trapped inside and time to flashover would be shortened.  Very big fire would be resulted in burning almost all combustibles.

10. 10 FSI Codes FRC Codes MoE CodesMoA Codes  may not be sufficient for providing fire safety in some buildings with special designs.  The prescriptive codes, basically on

11. 11 How can those codes apply to ultra highrise building? Might be OK for these !

Design rejected Design revised Figure 1: Process for approving fire safety designs  There is no engineering performance- based fire codes (EPBFC) yet.  The authorities (i.e. BD) accepted that “engineering approach” for passive fire safety design since 1998.
