The computer program of disaster simulation was developed and the calculational results were shown in the previous paper. But, the function of extinguishment was not included in the developed program. Therefore, a computer simulation program which takes extinguishment into consideration has been developed and their effects are analyzed by using sprinklers in this paper.
The total amount of supplying water and the amount for each tank have to be determined to calculate the effect of fire-extinguishment. Therefore, the distributions of supplying water for each tank are assumed as follows;
(1) Water is distributed only to the nearest tank from the first broken tank.
(2) Water is distributed proportionally to each broken time of tanks that can be calculated by heat of fire.
(3) Water is distributed in order to delay the time when the second tank is broken.
As an example, the damage progression for a model chemical plant based on the water distribution by the above methods is simulated. As a result, it is clear that the water supply of type (3) is suitable to extinguish. It is revealed that the proposed program in this paper is very useful for safety evaluation and protection against calamities for plants.
