Ergonomic research of early wear in power field activities
Introduction: Paying attention to and precocious detection of the reversible symptoms in the health state represent one of the main actual challenges in the world of work, in order to maintain the work capacities, avoid risky behaviours and, especially, the risk of early wear of personnel. This paper presents some results of a longitudinal study concerning the survey of a group of employees in the power field, in order to identify the possible work related wear phenomena and the specific occupational risks. Objectives: The main objectives of the study: 1. establishing a system of exposure indicators and biological response to the identified occupational risks and risk factors; 2. establishing a long term monitoring procedure of the physical and psychophysical capacities and the health state of the personnel; 3. settling some measures to maintain the safety and health at work, the optimal usage of the human resources, in order to preserve the health state and working capacity all along the working life. Methods: The study involved a multidimensional methodology, taking into account the premise of the human operator situation in a complex work system which parts are interconnected and, as a consequence, the influence of work on health state should be analyzed during a holistic approach. Results: The task analysis emphasized the exposure of personnel to a cumulus of accident and illness risk factors. The accident risks are mechanical, chemical, thermal, emerging from the power equipment and installations characteristics and operative service. The activity is carried on inside and especially outside the buildings and the personnel are exposed to the work environment risk factors. The ergonomic risks are also involved in the work of the investigated personnel: high physical load, manual handling, awkward postures, high demanding gestures, height work, covering difficult routes in extreme climate conditions, long term static postural load in the absence of adequate ergonomic conditions. The psychosocial risks and risk factors were also identified: work difficulty, work rhythm and break regime, temporal demands, high precision, repetitive actions, high responsibility, mental demands as perceived by the employees etc. The existence of occupational risk and overload factors is reflected in the personnel morbidity. The cardiovascular disorders are rated as being on the first place. The musculoskeletal disorders are also pointed out. The mental health analysis showed that the whole investigated group is situated in the limits of a total normality, with the absence of eventual significant psychopathological symptoms, with good mental health and comfort state. The physical and physiological capacities were investigated and analyzed in relation with the general population norms, showing good physical effort capacity, depending on the task demands and correlating with the periodic medical investigations. Conclusions: By correlating the health state and work demands and work conditions analysis the study emphasized the occupational risk factors which can contribute, together with the extra-occupational and individual factors, to the etiological-pathogenesis of the investigated personnel possible illnesses. In the perspective of health state, the investigated personnel are able to effectively carry on the specific work tasks.
