In the paper the problems identified during the review and evaluations of correctness of applying safety at work regulations, and the correctness of the production processes on the production hall in the internal transport are analyzed. During the review a very high noise level which was close to the upper limit of the norm and amounted 83 dB in the production hall was verified [9]. To identify source problems a tool "5W+1H" was used - analysis 5 x why and Ishikawa diagram. Research results were a base of drafting the project of improving wagons for transporting production parts and components what allowed to lower the noise level in the production hall. In the project financial and immaterial benefits resulting from the project implementation were calculated, as well as few lowered occupational risks which occur in the unit. The project was carried out in a production unit in the household industry considering the data sensitivity the unit name where the project was carried out wasn't revealed. An identification of economic effects as a result of eliminating the exaggerated noise sources made during the in-house components transport from magazines into the factory floors was a purpose of the project research.(original abstract)
