A Study on Human Behavioral Pattern and the Design of Escape Stair
Fire Science and Engineering, volume 12, issue 4, 1998, Pages 3~12
The purpose of this study is to examine that the escape stair of high-rise buildings has to be designed as a left-handed stair(a stair being designed to turn left whicle we go down the ground floor) judging from fire-safety point of view. Most of Korean people are right-handers. In case of right-handers it was found that the occupant's escape speed using a left-handed stair is more convenient and fast than of a right-handed stair(a stair being designed to turn right while we go down the ground floor). But most of the escape stair of high-rise buildings in Korea was designed as a right-handed stair. The fire code therefore should be provided that the escape stair of high-rise buildings should be a left-handed stair.
Explosion Riskiness with Flying of Carbon Black Dust by Hartman
Fire Science and Engineering, volume 12, issue 4, 1998, Pages 13~19
We investigated the weight loss according to temperature using Thermal Gravimetric Analysis(TGA) in order to find the thermal hazard of carbon black(Hi-Black 10, Hi-Black 50L) dusts, and the properties of dust explosion in variation of the surface functional groups and specific surface area of their dust with the same particle size. Using Hartman's dust explosion apparatus which estimate dust explosion by electric ignition after making dust disperse by compressed air, dust explosion experiments have been conducted by varying concentration and size of carbon black dust. The explosion pressure of both carbon black increased as the specific surface area increased. The results indicated that Hi-Block 50L of which specific surface area was larger three to four times than that of Hi-Black 10 was much easier of dust explosion.
Planning for Safety Control on LPG Distribution Depot
Fire Science and Engineering, volume 12, issue 4, 1998, Pages 21~30
The safety of LPG vessel storage has been simply designed and controled with blast wave barrier structure concept regardless of its quantity or hazardous situation. The limit of regal controls on LPG vessel storage need to be identified in terms of safety buffer distance from LPG explosion. The level of overpressure effect and heat radiation to the neighbouring structure and human activity required to be estimated to find the gap between existing controls on such storage. PHAST and IAEA manual for risk rankings and assessment had been applied to get the required safety distance for neighbouring facilities, Japanese legal control for such facilities were also investigated. To this context the issues on LPG vessel storage required additional safety distance between existing blast wave barrier structure and safety separation distances.
Microstructure Characteristics of Concrete Exposed to High Temperature
Fire Science and Engineering, volume 12, issue 4, 1998, Pages 31~40
Very often, whether accidentally or intentionally set fire, according as building are elevated, varied or complicated day by day. It is of primary importance that we have a treatment of fire damaged structure. In general, strength and elasticity modulus of heated concrete are reduced. Product background of cement, sand and coarse aggregate differ from country to country, so that thermal behaviour of concrete make a difference in high temperature. To cope with demand, this paper is a study on relation to microstructure and strength reduction. In consequence of experiments, concrete exposed to high temperature are estimating the reduction of mechanical properties in comparison with microstructure characteristics which are abtained from the SEM/EDX, XRD and DSC-TG analysis of heated specimens under various temperature.
A Study on the Effects of Flame Retardants in Unsaturated Isophthalic Acid Polyester Resin
Fire Science and Engineering, volume 12, issue 4, 1998, Pages 41~49
In this study, the thermal improvement of an isophthalic acid polyester resin by the incorporation of flame retardants has been investigated. Aluminium hydroxide, antimony oxide and alumina powder were used to formulate the flame retardant systems. The improvement of an isophthalic resin by incorporating aluminium hydroxide is dramatic(burning rate and smoke emission are reduced), although the mechanical property is decreased significantly. The addition of small amount(2.5 phr) of antimony oxide produces high char yield(31%) which acts as a protective layer on the surface of the resin.
Flammability Characteristics of Unsaturated Polyesters for FRP
Fire Science and Engineering, volume 12, issue 4, 1998, Pages 51~57
The thermal behavior and the flammability characteristics of four different unsaturated polyester resins were studied by performing a series of thermal analysis experiments and laboratory scale fire tests. The results of TGA and DSC reveals that the vinylester type resins have superior thermal performances when compared to the isophthalic type resins. The vinylester type resins formed a network shaped char surface after the thermal decomposition up to 55
. Consequently, the vinylester type resings have shown lower value of burning rate than that of iso type resins. Due to the high level of flammability and toxic smoke emission, the appropriate flame retardant system should be applied to the unsaturated polyester resings.
A Case study on the Escape Performance of Apartment Buildings
Fire Science and Engineering, volume 12, issue 4, 1998, Pages 59~69
As high-rise Apartment buildings increase the importance of fire prevention and escape performance. While these buildings provide dwellers with much more houses, they have the basic escape safety problem in their apartment buildings. In these respect, this study aims to present the Principles of Fire protection for the escape performance of apartment buildings. This study reviews basic theories of escape in apartment buildings. I figure out the characteristics of the fires in apartment buildings by case studying the fire in the apartment buildings, and find out the existing problems for escape performance and fire prevention by surveying. In this study, the major findings are as follows: The planning method should be based on the escape performance. In the planning stage, fire safety should be considered more seriously than law and economic factors.
