Abstract
A disaster simulation program by using a personal computer has been developed in order to investigate the safety evaluation for accidents in plants. The devised matters for program are as follows;
(1) The difference of the effects of location, capacity and kind of tanks on disaster can be calculated.
(2) The effect of dyke height on disaster can be calculated.
(3) The computational results can be graphically shown by personal computer.
(4) The affected region for human body by heat and explosive pressure can be calculated.
If a tank and pipes in plant have been destroyed by earthquake and so on, the gas or liquid in it will be leaked and fire or explosion will occur. The effects of the damaged tank on another ones are calculated by both heat and pressure of explosion.
As an example, the damage progression with time for a model petrochemical plant has been calculated. As a result, the effects of oil dyke and location of tanks on disaster have been analyzed. It is revealed that this program is very useful for safety evaluation and selection of site of fire monitoring system for plants.
