Conception of ergonomic interventions and challenges during Covid-19 pandemic

ABSTRACT

Introduction: The Covid-19 pandemic shifted ergonomists’ focus from work optimization to health-related interventions. For over a year, safety measures were primarily linked to limitation of infection with the new coronavirus. The paper aims to propose a framework for conception and evaluation of ergonomic interventions and to present major challenges faced in implementation of the framework during the pandemic. Material and Methods: The proposed framework comprises comprehensive methodology for assessment of physical environment parameters and ergonomic risks, and proposal of solutions. Methods used are RNUR, software solution based on REBA and OWAS and proposed methodology for physical environment assessment based on ISO standards and Romanian standards for determination of noise, dust, lighting and microclimate. Analysis of key challenges faced during implementation and potential causes are also presented in a dedicated section. Results: The framework was applied for development of ergonomic interventions in two companies. The most prominent risks identified were noise, uncomfortable postures, standing, manual load handling (lifting, pushing, dragging, carrying), torso twisting/bending. Conclusions: The Covid-19 pandemic negatively impacted the success of implementing participatory ergonomics principles, imposing the need to re-adjust strategy and find creative solutions for ensuring success of the interventions. However, the interventions were successfully finalized, the remaining objective being long-term evaluation of the intervention.
