IMO (International Maritime Organization) recognized that chronic exposure to benzene vapor in air may cause leukemia even if the concentration is very low, such as a few parts per million. Since benzene is widely used to make some types of pesticide, paint, medicine and so on, large quantity of benzene is produced in Japan. About 1.3 million tons of benzene are transported by the chemical tankers for one year in Japan. The concentration of benzene gas emitted from the cargo tank of the chemical tanker engaged in the bezene loading operation isn't the order of ppmv, but percent in volume. An estimation tool is needed to evaluate the working environment level on the chemical tanker. Taking acount of mechanism of diffusion in the cargo tank, we developed a new calculation model to estimate the concentration of benzene gas emitted from the cargo tank placed in the chemical tanker during the benzene loading operation.
