Fire recurrence experiments are conducted to investigate the causes of fire caused by the fumes of organic chemicals in small and medium-sized factories using volatile organic compounds (or organic solvents). Gas diffusion rates of volatile organic compounds are measured at temperature ~ 200°C. As a result, xylene is ignited in the fume generated above 180°C and ethyl acetate is ignited even at room temperature. The diffusion rate of the gas is increased rapidly as the temperature increases, so that the diffusion rate of the fire is increased exponentially when the temperature of the container and the surrounding of the organic solvent are increased. Measures should be taken by rapid cooling of the fire ignition point, blocking of air, and formation of an upper barrier film in the container containing organic compounds.
