New Developments in Explosion Protection Technology Robert Zalosh Worcester Polytechnic Institute Worcester, MA 01609 USA For Presentation at Fire and Emergency Services Asia 2005 Singapore February 22– 26, 2005 Abstract New developments in explosion protection technology during the last five-to- ten years include: new explosion prevention and suppression systems using either reticulated foam inserts, fine water mist, or onboard oxygen concentration reduction; explosion isolation systems; flameless deflagration venting devices; and new products and methods for design, construction and analysis of blast resistant structures. Key features of these new developments, and the corresponding explosion protection standards that provide guidance on their use, are summarized in this paper. Many of the developments and applications are pertinent to industrial facilities processing or storing large quantities of flammable gases, vapors, or combustible powders. Other applications include military and commercial aircraft, tanker trucks and rail cars, ship fuel tanks, and portable containers for flammable liquids. Blast resistant structure technology has the most diverse applications, encompassing blast and projectile resistant walls and buildings. Introduction Several international events and trends in the last five to ten years have stimulated the development of new explosion protection technology. These include: 1) more regional and international explosion protection standards, 2) some widely repo
