Abstract

The water treatment process involves the use of chlorine, a potent toxic substance and ecotoxicant, which classifies industrial sites that perform water chlorination as chemically hazardous sites. The aim of this study is to test an original methodology for assessing the environmental risk associated with a man-made emergency at a chemically hazardous site engaged in water chlorination. The study employed an environmental risk assessment methodology based on expert evaluation. The environmental risk level was determined by comparing the environmental hazard indices of the chemically hazardous site with its environmental vulnerability. The application of this methodology enables the scientifically grounded zoning of areas surrounding chemically hazardous sites according to environmental risk levels. For the environmental object located 200 meters from the chlorine tank, the risk level was assessed as low. This assessment is mainly attributed to the effective operation of the occupational safety management system at the studied industrial site and the low level of environmental vulnerability.
