    • External and internal load in the context of methods for assessing musculoskeletal load
    prof. dr hab. inż. DANUTA ROMAN-LIU

    The article presents the concept of the relationship between the load defined as external and the internal load, defined as the reaction of the employee's body to this impact. Methods for assessing the impact resulting only from work activities (methods for assessing external load) and those that take into account the individual characteristics of the employee (methods for assessing internal load) have been characterized. Particular attention was paid to the input variables to the external load assessment methods relating to the body position (joint angles) and the forces exerted. The presented analysis discusses the differences and similarities in both types of methods.

     



    Eye hazards during manual laser welding – analysis of methods for determining exposure to laser radiation
    dr inż. GRZEGORZ OWCZAREK , dr inż. JOANNA SZKUDLAREK , dr inż. MARCIN JACHOWICZ , dr MAŁGORZATA OKRASA

    Manual laser welding, one of the latest advancements in welding technology, poses specific occupational hazards, particularly for welders' eyes exposed to harmful optical laser radiation. Despite the widespread use of this technology, there is a lack of clear and consistent methods for assessing occupational risk. This article aims to fill this gap by analyzing various methods of determining the maximum permissible and expected exposure to laser radiation, as well as defining the required protection level for filters protecting against laser radiation. The results of this analysis may assist in creating more effective safety protocols for welders conducting manual laser welding, which is crucial for their health and safety.
