Abstract

Through a survey of perception of environmental risks in the casting sector of aluminum alloy wheels in an Automobile company. It was concluded that the employees were not satisfied with the conditions of the place due to the high noise of the sector. This work proposes an analysis of the improvement process in the work environment, preventing occupational diseases and making the environment of the company's foundry sector effective without changing the manufacturing process. When it comes to a High Sound Pressure Level or more commonly called noise, it must be understood that acoustic trauma, temporary partial hearing loss can occur as well as permanent total hearing loss. For this to be avoided, it is necessary to monitor the exposure of workers with or without protection, whether environmental through measurements of the noise level using their own instruments and / or biologically through audiometric exams. Through this bad condition, which turned our attention to applying the improvement in the operational sector to reduce the noise level where it caused a sensation of discomfort in all employees.
