Globally, Spray painting operation is the most common operation carried out in automobile body workshop for decorative and coating of vehicles body. The hazardous nature of spray painting is that emits voc in larger proportion causing destruction to both human health and environment. The voc emission rate is calculated thus ensuring safety to the environment. Threshold value for proposed or existing project should lay between the threshold limit as prescribed by EPA. (Under Title v permit- clean air act). when the emission rate is severe, it causes several health issues to the workers exposed to spray painting, the health study of workers along with economic and technical analysis is carried out in this project. A general feasibility study is carried out in the areas of Salem where 20 number of spray-painting shops were located. The waste manifestation of entire areas is to be analyzed thoroughly ensuring better environment and ensuring the workers a clear knowledge about personal protective equipment and other advanced coating operations.
