Fire-hazard Materials as a Cause of Fire in Buildings and Cities and Their Related Modeling in Fire-pattern to Grow Big Fire

Abstract

Recent developments in petrochemical and automobil industries have stimulated the use of many new plastic materials in building constraction and the increase in the stocks of fuels in and around cities. Increasing population in and around cities as the result of the prosperity in the expanding economies and industrial activities have stimulated the constraction of many tall buildings and apartments and under-ground marketing centres, which have changed used-to-be fire patterns particularly concerning smokes. Heavy traffics in down-town areas caused by the over-crowding cars will be expected to be a cause of the serious fire-sources by the sudden big earthquake and to prevent the evacuation of citizens. Consequently, the rechecks on the fire-hazardness of those materials in tall buildings and cities relating the city-constraction plan and the change in the fire-patterns will be the serious problems for the civil-safety. Therefore, in the present paper the fire-hazardness of organic building-materials and fuel-stocks in cities will be referred to as a criterion of fire-source and the characterization of fire-patterns in the above liquidous and solid fire-hazard materials will be surveyed for the criterion on the fire-modeling of big-fires in buildings and cities.Finally, the necessity in the development of the studies on control-technique of fire between elements and systems will be emphasized for the earlier prevention of big fire based on the above fire-pattern modelings to exclude the excess fear and limitation in the use of plastic materials and fuel-stocks necessary for the modern civil livings.
