A job safety analysis (JSA) is a one of the safety tools and techniques to evaluate the potential hazards associated with each work and provide the proper control measures for the recognized hazards. In cement industry, the job is categorized into nonroutine job, new job, and frequently occurring accident job, and this tool is applied.
