Various problems regarding the process of loading baggage on aircraft have been identified in terms of functioning of the “man – machine – working environment” system, causing health problems in a number of workers. This study tries to offer an effective solution to the problem. We have tried to prove the connection between our subjects’ health problems and their working environment. We have compared their workload before and after the improvement of their working environment, calculating energy consumption in order to show the effectiveness of the improvement. An evaluation of the study’s scientific contribution within the consistent and comprehensive approach to observing and exploring the influence of various parameters on working ability is called for. SAŽETAK: Kako su u procesu utovara prtljage u zrakoplov uočeni brojni nedostaci u pogledu funkcioniranja sustava „čovjek-stroj-radna okolina“, zbog čega je došlo do zdravstvenih problema kod više radnika, nastojalo se u ovom radu ponuditi kvalitetno rješenje. U radu se nastojala dokazati povezanost obolijevanja naših ispitanika s radnom okolinom u kojoj oni rade, i to u funkciji opterećenja prije sanacije i poslije sanacije radne okoline, odnosno putem energetskog proračuna prikazati učinkovitost sanacije. S tim u vezi, potrebno je sagledati znanstveni doprinos rada u sustavnom i integralnom pristupu promatranja i istraživanja utjecaja svih parametara na radnu sposobnost zaposlenih.
