Ergonomic solutions to support forced static positions at work

Abstract

Abstract. The article analyzes the available ergonomic constructions used for the support of the musculoskeletal system during static, prolonged work performed in forced positions. Possible evaluation methods are presented as well as ergonomic considerations of work performed in inclined positions, where there is no possibility of influencing the working plane. As a result of the presented work, a set of criteria has been proposed and the requirements for methods which can be used to evaluate the technical constructions supporting the worker during tasks performed in forced and static positions.

Success Factors of Ergonomic Committee's Performance within Production Companies

“…The use of an ergonomic approach in an organization gives many benefits that the organization and its individual divisions can achieve in managing the quality of work (Górny, 2020), but also beyond this scope, especially in the industries where ergonomics was not the key consideration (Suszyński, Butlewski, and Stempowska, 2017). Integration of ergonomics in the management system results, among others (collected by Domingues, Sampaio, and Arezes, 2012), efficiency and effectiveness improvement, bureaucracy decrease, costs reduction, objectives, processes and resources alignment, decrease in disruptions to plant operations, synergistic "energies" maximization, redundancies elimination, resources optimization.…”

Role of Ergonomics in Inducing Dynamicity by Transforming Sedentary Computer Workstation

“…This is calculated by parameter called percentage of Maximum Holding Time (MHT). Loads are said to be acceptable if the duration of the load is less than 20% MHT [1]. The amount of time after which the body under observation and experiencing certain load can no longer uphold the burden helps acquire the MHT.…”

“…The amount of time after which the body under observation and experiencing certain load can no longer uphold the burden helps acquire the MHT. Prolonged static load on the body can lead to physical discomfort in turn affecting the workers ability to work efficiently and increasing the risk of musculoskeletal system disorders [1].…”

“…This review paper discusses about the problems caused from having a stationary, desk-bound job for prolonged working hours without the appropriate and convenient work environment and how their physical and mental health are adversely affected by it, along with statistical justification to support the information. The need to maintain a rigid and unhealthy posture at work has been researched upon and results provide us with information regarding its effects on the musculoskeletal system that lead to illnesses known as WRMSDs (work-related musculoskeletal disorders) [1]. It will also cover potential solutions in helping reduce the musculoskeletal system disorders.…”

Proposal of a System for Estimating the Assembly Time in Small and Medium-Sized Enterprises

“…The assembly process, as a part of the production process, is characterized by specific aspects to be considered in all phases and procedures relating to the design, operation, assembly sequence determination, ergonomics and rationalization of the assembled product and the entire assembly process [1][2][3][4]. In this regard one of the key concepts whose application is required and extremely useful in assembly is the so-called Lean Manufacturing.…”
