Presentation Transcript

  1. Supporting the following conferences • Fire Conference 2004 - Total fire safety concept, Hong Kong December 6-7, 2004, organized by Professor W.K. Chow, Director, Research Centre for Fire Engineering, The Hong Kong Polytechnic University, President, Society of Fire Protection Engineers, Hong Kong Chapter • 2005 Asia-Pacific Conference on Risk Management and Safety, Hong Kong, 1-2 December 2005, organized by: The Hong Kong Association of Risk Management & Safety • 7th Asia-Oceania Symposium Fire Science & Technology, 20-22 September 2007, Hong Kong

  2. Offered in collaboration with • Research Centre for Fire Engineering, Areas of Strength: Fire Safety Engineering • University of Science and Technology of China • China Public Security • Over 160 attended • 1½ day Conference • ½ day Open Forum • 1 day Education Symposium on Fire Engineering

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

  4. International Symposium, 7th 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. 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. Many highrise buildings packed together EastWeek, 4 August 2004, pp. 76-77

  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. Accidental fire • 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. The Big Garley Building Fire 1996 Bus Fire: Burnt completely within 10 minutes

  9. Arson fire : Quite high frequency of occurrence? • Bank Arson 1994 • Karaoke 1998 Arson fire – MTR train vehicle EastWeek, 4 August 2004

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

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

  12. From Next Magazine, Taiwan, 10 July, 2003 508 m Taipei, Taiwan Ultra Highrise Buildings / Super Tall Buildings What to do?

  13. New project PBC design following MoE, MoA, FRC codes FSI design following FSI code Submission to BD Submission to FSD Design revised Design revised FEA Y FEA ? Approved ? Approved ? N Y Y N N Opportunities for revision ? Opportunities for revision ? Evaluation by fire consultant Y N N Y Considered by FSC, BD Approved ? N Y Opportunities for revision ? Design rejected Design rejected N Proceed to construction Design rejected Proceed to installation • 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.

  14. An Example: A shopping mall Shan Tung Street Entry Argyle Street Entry Discussed in more details later in a Cross-fertilizing meeting of SFPE Chapters in Asia-Oceanic Region.

  15. Long-throw sprinkler • No smoke reservoir • IR-detector • Water coverage • Atrium hot smoke test in site • 11 m smoke layer interface height • 2 MW design fire

  16. 137,000 m3 in volume Exceeding 60 m Height Fire safety provisions to comply with FSD/BD’s requirements

  17. Long throw sprinklers • Infra red flame detectors • Smoke curtain • Fire shutters • Smoke extraction system/Auto open make up air windows • Aspirating smoke detection system (VESDA) • Fully addressable digital automatic fire alarm system • Fire rated structural elements

  18. Sprinkler System Open Type Sprinkler Long Throw Sprinkler

  19. Long throw sprinklers distributed in 24 zones Arranged in parallel, 30o or 45o for each pair of long throw sprinklers Mounted at 3 m height Actuated by infra red flame detectors Long Throw Sprinkler Design Long Throw Sprinkler Head

  20. Infra Red Flame Detector Long Throw Sprinklers
