Abstract
This study provides a comparison and analysis of the predicted damages related to hazardous chemical substancesused in “A” solar cell manufacturing process. In order to predict potential damages, different accident scenarioswere established using the ALOHA model and the KOSHA guideline. This study evaluates chemical spills andleaks from cylinder and pipeline. Maximum distance of chemical movement, based on an initial concentration of150ppm, was estimated as up to 258m in summer and 251m in winter. The impacts of the leakage of chemicalssuch as ammonia, were dependent on the initial concentration of the chemical leaked, the atmospheric stabilityand temperature, and the wind speed. All of those however, were affected by air humidity.
