Abstract

Article The aim of this study was to evaluate the exposure of individual workers to ergonomic risk factors associated with upper, lower extremities and trunk WRMSDs and to assess entire body posture for risk of WRMSDs. The company that produces finished metal products (ironing boards) was chosen for the research. Rapid Entire Body Assessment (REBA) was used to assess the entire body posture for risk of WRMSDs. Rapid Upper Limb Assessment (RULA) method was used for ironing boards employees to evaluate exposure of the neck, trunk, arms and legs in relation to physical load. Our study proved that employees are subjected to WRMSDs due to the load on certain body parts during the work: shoulder and neck area, lower back, legs and arms. Forced work postures are an essential risk factor at work. Assemblers and packers are subdued to high risk level, but inspectors – to medium risk level, which corresponds to evaluation with RULA and REBA methods.

Abstract

In Latvia because of increased health problems caused by physical load, interventions with ergonomics solutions at the workplaces are necessary, improving not only working conditions, but also work abilities, especially for older workers. For the ergonomics risk assessments were carried out using such methods as: Key Indicator Method (KIM), and the Work Ability Index (WAI). Inquiry data showed that workers in all age groups complain about discomfort or pain in the back, legs and hands. Assessing physical workload during operations of lifting or moving heavy loads, it was stated that the assemblers and loaders in elderly groups were exposed to most severe loads corresponding with the high KIM risk degree IV, but sawyers - middle risk degree II-III. The establishment of new technologies for workplaces and ergonomic aids (pneumatic and automatic lifting, etc.) remarkably decrease the KIM risk degree- down to I -II, especially for older workers. WAI analysis demonstrates differences within age group before and after the ergonomics interventions. In order to successfully retain employment and work abilities of older workers the improvement of manufacturing process by implementing ergonomic solutions is necessary. [ABSTRACT FROM AUTHOR]
