Abstract(s)
Os princípios gerais da promoção da proteção e segurança e saúde dos trabalhadores,
consagrados na lei, estão presentes e desenvolvidos em regulamentação específica para
os setores económicos.
Com as lições aprendidas face às ocorrências industriais de grandes dimensões, e ao seu
estudo e investigação, foram produzidas diretrizes internacionais para a prevenção de
explosões e incêndios.
As explosões e incêndios provocados pela presença de atmosferas explosivas, derivados
a gases, vapores inflamáveis ou poeiras não são as causas mais frequentes de acidentes
de trabalho, contudo quando ocorrem têm consequências dramáticas em termos de perda
de vidas humanas, impactes ambientais severos e custos económicos elevados.
Na ocorrência de uma explosão, os trabalhadores ficam expostos a riscos devido aos
efeitos que surgem sob a forma de radiação térmica, chamas, ondas de pressão, projeção
de destroços, fumos e gases tóxicos da reação e dos reagentes, e à falta de oxigénio
existente no ar, indispensável à respiração.
Com base nos contributos das diretivas europeias e a transposição para direito interno
dessas regulamentações, foram estabelecidas regras para a segurança e saúde dos
trabalhadores no âmbito da proteção às atmosferas potencialmente explosivas.
No presente, as empresas têm a responsabilidade de elaborar um manual de proteção
contra explosões e mantê-lo atualizado de forma a proteger os seus trabalhadores na
presença de atmosferas potencialmente explosivas.
Para a elaboração desse manual, é necessário recorrer a um conjunto de documentos
normativos e legais para desenvolver e identificar essas áreas, bem como promover
medidas de prevenção e proteção.
The general principles of the promotion of workers' protection and safety and health, enshrined in the law, are present and developed in specific regulations for economic sectors. With the lessons learned from large-scale industrial occurrences, and their study and research, they have produced international guidelines for the prevention of explosions and fires. Explosions and fires caused by the presence of explosive atmospheres, which are derived from gases, flammable vapors or dust are not the most frequent causes of occupational accidents, but when they occur they have a dramatic impact in terms of loss of human life, severe environmental impacts and economic costs high. In the event of an explosion, workers are exposed to hazards due to the effects arising in the form of thermal radiation, flames, pressure waves, projection of debris, fumes and toxic gases from the reaction and reagents, and the lack of oxygen in the air, indispensable for breathing. Based on the contributions of European directives, the transposition into national law of these regulations, rules have been established for the safety and health of workers in the field of protection of potentially explosive atmospheres. At present, companies have a responsibility to develop an explosion protection manual and keep it up-to-date in order to protect its workers in the presence of potentially explosive atmospheres. For the preparation of this manual, it is necessary to use a set of normative and legal documents to develop and identify these areas, as well as to promote prevention and protection measures.
