Este trabalho académico aborda o estudo da relação de dois tipos de riscos ocupacionais, os riscos ocupacionais e os riscos psicossociais. Com este trabalho procurámos determinar se os riscos psicossociais influenciavam os riscos ocupacionais a que os trabalhadores estão expostos e se dessa forma contribuíam para o aumento dos acidentes de trabalho, falhas humanas, atos inseguros, na execução das suas tarefas.
O contexto laboral permitiu que observássemos as tarefas que os profissionais executavam mas, devido à programação de trabalhos interna, parte das tarefas tiveram de ser estudadas tendo por base as instruções de trabalho, que servem de referência para a certificação de qualidade e ambiente. O horário de trabalho, o tempo de pausa, o horário de refeição, os turnos rotativos, o horário de piquete, todas estas informações foram fornecidas pela organização. A metodologia para a recolha de dados foi por observação direta, intensiva e por preenchimento de um questionário específico para a avaliação dos riscos psicossociais. Utilizámos dois métodos de avaliação matricial em que depois de fazermos a análise estatística dos dados podemos valorar o risco através da conjugação dos fatores de formação de risco.
Avaliados os riscos, verificámos que são necessárias medidas corretivas urgentes, tanto preventivas como de proteção, na execução da amostra de tarefas definidas no estudo. Através da análise estatística do absentismo e acidentes de trabalho, confirmámos a necessidade da avaliação de riscos tanto na execução das tarefas como em aspetos organizativos do trabalho.
Não conseguimos relacionar os riscos psicossociais com as falhas ativas, atos inseguros, mas estão diretamente relacionados com as condições latentes, fatores organizacionais que constituem uma barreira entre o perigo e o acidente.
This academic work talks about the study of the relation of the relation between these two types of occupational risks, the occupational risks and the psychosocial risks. With this study, we sought to determine if psychosocial risks influenced the occupational hazards to which workers are exposed to and if this contributed to the increase in work accidents, human failures, unsafe acts, and the execution of their tasks. The work context allowed us to observe he tasks that the professionals performed, but due to the programming of the internal work, part of the tasks had to be studied based on the work instructions, which serve as a reference for quality and environmental certification. Work Schedule, break time, rotating shifts, picket hours, all this information was provided by the organization. The methodology for data collection was by direct observation, intensive and by filling a specific questionnaire for the evaluation of psychosocial risks. We used two matrix evaluation methods in which after performing the statiscal analysis of the data we can assess the risk through the combination of risk formation factors. After evaluating the risks, we verified that urgent corrective methods are necessary, both preventive and protective in the execution of the sample of tasks defined in the study. Through the statistical analysis of absenteeism and work accidents, we confirmed the need for risk assessment both in the execution of the tasks and in the organizational aspects of the work. We couldn´t relate psychosocial risks to active failures, unsafe acts, but are directly related to latent conditions, organizational factors that constitute a barrier between danger and accident.
