A Study on Combustion Characteristics of Starch
Fire Science and Engineering, volume 15, issue 2, 2001, Pages 1~5
We had investigated combustion properties of starch. Decomposition of starch scavenged by pre-cipitator of spinning factory with temperature were investigated using DSC and TGA. Combustion properties of starch according to amount were checked as temperature variation according to time using spontaneous ignition apparatus. Moreover, combustion properties with blowing or without blowing condition were checked in spontaneous ignition apparatus. As results of thermal analyses, increase in raising temperature causes initial smoldering temperature to move towards low temperature section. In addition, as amount of starch was increased, initial smoldering temperature was lowered. All of combustion forms were smoldering combustion. Initial smoldering temperature was low more slightly with blowing condition than without blowing condition in spontaneous ignition apparatus, which condition made heating value high.
A Study on the Cooling Effect of a Water Fire Extinguishing Agent Containing NaBr
Fire Science and Engineering, volume 15, issue 2, 2001, Pages 6~12
The objective of the present work is to examine the cooling effect of a water fire extinguishing agent containing NaBr(30%, w/w). The carbon steel and teflon were used as a hot solid. The temperature on the hot solid surface ranged from
and water droplet size was 2.6 mm in the experiments. It is suggested that regardless of the hot solid material, the indepth temperature of the case of NaBr solution is lower than that of pure water and the variation of indepth temperature of teflon is higher than that of carbon steel. Regardless of the hot solid material, the time averaged heat flux of the case of pure water is higher than that of NaBr solution. the apparent evaporation time of the case of pure water is shorter than that of NaBr solution.
Deregulation of the Fire Prevention Legislation; and Its Impact on Fire Occurrence - Case of the United Kingdom -
Fire Science and Engineering, volume 15, issue 2, 2001, Pages 13~19
The OECD defines regulatory reform as both better regulation and deregulation, and emphasizes that governments must continue to regulate in areas such as environmental quality and safety. In contrast, Korean regulatory reform in fire services in the 1990s shows quite a strange trend, having been carried out only to the direction of softening and abolishing regulations. In the UK, fire prevention legislation has been strengthened since the enactment of the Fire Precautions Act 1971, and the Building Regulations 1991, which apply to all new buildings including a private house, require that there should be at least one smoke alarm on each floor. This research shows that the tightening of fire prevention legislation in the UK has promoted fire safety, which is very instructive for Korean fire services. In order for Korean fire services to protect citizens'lives and property from fires, one of basic directions of regulatory reform, to improve the quality of regulations relating to safety, health and the environment, should be observed strictly. Moreover, the flexibility of the basic direction of regulatory reform should be ensured so that the regulations concerning safety could be even increased under the overall reform strategy of reducing all regulations.
Managing the Vulnerability of Megacities in North America and Europe to Seismic Hazards
Waugh, William L. ;
Fire Science and Engineering, volume 15, issue 2, 2001, Pages 20~30
The science and technology of seismic hazard mitigation are increasingly being shared among scientists and policy makers around the world. Administrative expertise is also being shared. While there is still tremendous unevenness in technical and administrative capacities and resources, a global community of emergency managers is developing and there is a globalization of expertise. Hazards are better understood, tools for risk assessment are improving, techniques for hazard mitigation are being perfected, and communities and states are implementing more comprehensive disaster preparedness, response, and recovery programs. Priorities are also emerging and hazard mitigation has emerged as the priority of choice in North America and Europe. An increasingly important component of hazard mitigation is resilience, in terms of increased capacities for disaster mitigation and recovery at the community and even individual levels. Each year, more is known about the locations and natures of seismic hazards, although there are still unknown and poorly understood fault lines and limited understanding of related disasters such as tsunamis and landslides. More is known about the impact of earthquakes on the built environment, although nature still provides surprises to confound man's best extorts to reduce risk. More is known about human nature and how people respond to uncertain risk and when confronted by certain catastrophe. However, despite the increased understanding of seismic phenomena and how to protect people and property, there is much that needs to be done to reduce the risk, particularly in major metropolitan areas.
A Study on Characteristics and Prevention of Arson
Fire Science and Engineering, volume 15, issue 2, 2001, Pages 31~45
A purpose of this study is to enhance the concern and cognition of people and to search for the effective approach on the control of crime arson which is increasing recently. To accomplish this purpose, it is important to organize three other factors, such as enforcement and strengthening of residents self defense system about fire, establishment of more complicated arson control system of the public agency, and strengthening the correction activity of arson psychologically. It is necessary to construct the cooperation system between community police and fire police and to enforce the friendship between residents and public agency.
A Comparison of the Prediction of Sprinkler Response Time Applying Fire Models
Fire Science and Engineering, volume 15, issue 2, 2001, Pages 46~52
To evaluate the usability of compartment fire models for predicting sprinkler response time, fire experiment was conducted and measured sprinkler response time. The experimental data was compared with zone model "FASTLite"and field model "FDS"and field Model "SMARTFIRE" A Compartment fire conducted in a 2.4 m by 3.6 m by 2.4 m ISO 9705 room and measured H.R.R was approximately 100.3 kW. In test, Sprinkler activation temperature used is
and responded at 198s. The output of FASTLite, SMARTFIRE and, FDS for this fire scenario were 209s, 183s, and 192s, respectively. As a results, prediction using FDS model approached to that of test very closely and other models showed good approximated results also.
An Evaluation of Flame and Fire Retardant Performance for Welding Blanket
Fire Science and Engineering, volume 15, issue 2, 2001, Pages 53~58
This study was undertaken to evaluate the performance of flame retardant for fire precaution from sparks at welding-cutting process in industry sites such as shipbuilding yard and chemical factory. As the results of the performance experiment, six kinds of welding blanket in samples that are used commercially had enough in the performance of flame retardant. Nevertheless, the performance to fire precaution un welding blanket shows that the coaling product of two kinds with fiber glass is not sufficient. The lower oxygen index to welding blanket is considered that it is more than 30 in domestic standard. We suggested that the performance improvement of flame retardant for welding blanket need continuously, and the guideline of the flame retardant to welding blanket should be considered and established.
Distribution of Heat and Smoke Related to Openings in Hise-Rise Apartment Building Fires
Fire Science and Engineering, volume 15, issue 2, 2001, Pages 59~79
The paper proposes alternatives for fire safety in architectural planning through heat-smoke distribution related to openings so that we decrease casualty and property loss by fire and lay a great emphasis on building high-rise apartments with consideration of fire safety in Korea. An analysis program(HFA-Heat Fluid Analysis) is built to perform simultaneously numerical analysis and experimental analysis on rooms, units and buildings. In consequence, on the first, fire prevention methods are required to be set up related to openings for design rooms since the flow of heat and smoke is influenced by the type of openings in high-rise apartments. Second, the numerical analysis showed that different planning types cause to show differences in the spreading time of heat and smoke to design the units of high-rise apartments. On the third, each unit building showed different fire behavior depending on openings by numerical analysis and small scaled experiment on heat and smoke flow.
A Study on the Safety Measures of Fire Protection in Hotel Buildings
Fire Science and Engineering, volume 15, issue 2, 2001, Pages 80~90
It is expected that hotel buildings will be large-scale, luxurious and multiplex according to the needs of modern functions. In addition, building users, who are many and unspecified persons, are short of information on the buildings, so that they may be injured or killed at the occurrence of fire accident. Therefore, in order to overcome such problems, hotel buildings need systematic fire protection facilities concerning particulars to pay attention to the safety on a fire and an evacuation. This study has investigated the following matters. First, it examined hotel use records, statistics relevant to fire accidents, a case investigation related to fire accidents, survey on actual performance of fire protection awareness. Second, it investigated the design planning matters of hotel buildings. Third, it demand to amend the law and regulations related to physical Protection after analyzing them. The purpose of the study is to protect human being and properties at the occurrence of fire accident, and to present basic material for design of hotel buildings to minimize damages and losses.
Modeling of the Velocity of the Ceiling Jet Front
Fire Science and Engineering, volume 15, issue 2, 2001, Pages 91~95
Decays of the ceiling jet front velocity under a circular ceiling are investigated. To simulate the ceiling jet in fires He and
gas were injected from a nozzle to the center of the ceiling. The jet fronts in the form of turbulent eddies were traced by a high-speed camera system. The instantaneous locations of the front were obtained from visual readings of visualized front, and the radial velocity was calculated from the information of the time and the location with respect to the front. The similarity and dimensional analysis were also carried out to reveal the relationship between the velocity decay and the radial distance. It was shown that the radial velocity of the front was inversely proportional to the radial distance in the fully developed region from the experimental results and the theoretical analysis.
