O presente relatório descreve as atividades desenvolvidas no âmbito de um estágio curricular realizado numa indústria de panificação ultracongelada no contexto do Mestrado em Segurança e Higiene no Trabalho. O estágio teve como foco a avaliação do risco de atmosferas explosivas numa sala de silos de farinha, área considerada crítica devido à presença de poeiras combustíveis e ao elevado grau de confinamento. A metodologia utilizada seguiu uma abordagem prática e operacional, adequada ao contexto industrial e alinhada com os requisitos legais e normativos aplicáveis à prevenção em atmosferas explosivas. A avaliação do risco considerou a frequência de formação de atmosferas explosivas, a probabilidade de existência de fontes de ignição e a gravidade das possíveis consequências, de acordo com os princípios definidos na legislação e nas normas técnicas em vigor. Como principal resultado do estágio, foi elaborado um Manual de Proteção para Atmosferas Explosivas específico para a sala de silos de farinha, integrando a caracterização da área, a classificação de zonas de atmosferas explosivas, o inventário de equipamentos certificados e a definição de medidas de prevenção e proteção. Este documento constitui um apoio à gestão de risco em atmosferas explosivas na empresa e contribui para o cumprimento das obrigações legais em matéria de segurança e saúde no trabalho. O estágio permitiu ainda o desenvolvimento de competências práticas na identificação dos perigos, análise de riscos e aplicação de requisitos legais e normativos em contexto industrial, reforçando a importância de uma abordagem sistemática e preventiva na gestão dos riscos associados a poeiras combustíveis.
ABSTRACT This report describes the activities carried out within the framework of a curricular internship conducted in a frozen bakery industry, as part of the Master's degree in Occupational Safety and Health. The internship focused on the assessment of explosion risks in a flour silo room, an area considered critical due to the presence of combustible dusts and the high level of confinement. The methodology followed a practical and operational approach, suitable for the industrial context and aligned with the legal and regulatory requirements applicable to the prevention of explosive atmospheres. The risk assessment considered the frequency of formation of explosive atmospheres, the probability of the presence of ignition sources, and the severity of potential consequences, in accordance with the principles established in the applicable legislation and technical standards. As the main outcome of the internship, an explosion protection document was developed specifically for the flour silo room, including the characterization of the area, explosive atmospheres zone classification, an inventory of certified equipment, and the definition of prevention and protection measures. This document supports explosive atmospheres risk management within the company and contributes to compliance with occupational health and safety legal obligations. The internship also enables the development of practical skills in hazard identification, risk analysis, and the application of legal and regulatory requirements in an industrial context, highlighting the importance of a systematic and preventive approach to managing risks associated with combustible dusts.
