Objectives. Musculoskeletal disorders (MSDs) are prevalent among airline baggage handlers due to manual materials handling. In this study, the Nordic musculoskeletal questionnaire (NMQ), the revised National Institute for Occupational Safety and Health (NIOSH) lifting equation, and the University of Michigan 3D Static Strength Prediction Program™ (3DSSPP) were used to analyze MSDs among baggage handlers. Methods. The NMQ was filled out by 209 baggage handlers and 46 arbitrarily selected baggage handlers were evaluated using the NIOSH method and 3DSSPP. Results. The obtained results showed that the most common MSDs occurred in the lower back region. The next risky regions included knees, neck, and upper back, respectively. The NIOSH results confirmed that the subjects lifted loads heavier than the permitted limit and their lifting postures were inappropriate. The results of the 3DSSPP also indicated that compression forces exceeded the NIOSH limit in these awkward postures. Conclusions. Relying on this study, holding compulsory ergonomic lifting training courses could be proposed for workers and regulations adjusting an upper limit for maximum baggage weight must be also enacted in order to improve occupational health and prevent the prevalence of increasing MSDs.

Ergonomiczne czynniki ryzyka w zawodzie górnika

Artykuł jest zarysem problematyki schorzeń narządów ruchu uwarunkowanych ergonomicznymi czynnikami ryzyka obecnymi w sposobie wykonywania pracy. Przedstawiono w nim wyniki badań i zastosowań realizowanych w USA. W syntetyczny sposób przedstawiono zagrożenia ergonomiczne towarzyszące pracy górnika oraz ich skutki dla zdrowia - dolegliwości mięśniowo-szkieletowe. Wskazano również na wybrane aspekty interwencji ergonomicznej w pracy górnika.

In this paper authors discuss work related musculoskeletal disorders among mineworkers. Some effects of scientific investigations and practices in mining conducted by NIOSH and MHSA in USA are presented. Ergonomics risk factors that accompany mineworker occupation are described. Issue of ergonomics intervention and some practical aspect of application ergonomics criteria in evaluation cab of construction equipment is presented.
