Abstract(s)
Os colaboradores que realizam a sua atividade profissional, no setor das águas residuais,
reconhecem que a sua atividade é perigosa.
Esse conhecimento, foi adquirido pela experiência obtida ao longo dos anos, pelas várias
formações e pelas notícias de acidentes, muitas vezes mortais, que têm acontecido na
atividade.
Muita das vezes, os colaboradores têm dificuldade em aceitar o risco, porque na
realidade não existe um histórico conhecido do que se passa no interior das redes de
drenagem de águas residuais e consideram que o risco é apenas teórico.
Os portugueses são um Povo muito ligado à Cultura Popular,e são os ditados populares
que melhor sintetiza as ideias expressas pelos trabalhador português “Ver para Crer,
Como São Tomé” (SOUSA, Marcelo Rebelo de, Os Evangelhos de 2001, Lisboa,
Bertrand Editora, 2001].
O objetivo principal com este trabalho, foi evidenciar que existem gases no interior das
caixas de visita, mas principalmente, demostrar que seu aparecimento e respetiva
concentração, é variável e que ocorre sem aviso prévio!
Tornando assim, os trabalhos no interior das caixas de visita e das redes de drenagem
de águas residuais domesticas, locais perigosos para quem opera no seu interior, sem a
correta utilização dos equipamentos de proteção individual, (Epis e Epc). Sendo necessário, reforçar, a constante informação e formação para a utilização dos
equipamentos de proteção individual e coletiva.
Com o presente estágio, pretendeu-se iniciar um registo histórico de medições nas redes
de drenagem de águas residuais domésticas.
Com o resultado das medições que serão obtidas, pretende-se uma “Radiografia
Fotográfica” ao interior das caixas de visitas das redes de drenagem de águas residuais.
Com os resultados deste estudo, pretende-se contribuir de forma clara e objetiva, para
os perigos iminentes que existem efetivamente, no interior das redes de saneamento,
com a presença de altas concentrações de gás sulfídrico, nocivo para a vida humana!
Employees who perform their professional activity in sewerage systems, recognize that their activity is dangerous. This knowledge has been acquired through experience gained over the years, some by training event, other by the news of accidents, many of them deadly, which have happened in the activity. Much of the time, employees have difficulty accepting the risk, because in reality there is no known history of what goes on inside the sewerage systems, and consider that the risk is only theoretical. The Portuguese are a people very connected to the Popular Culture, “I accept that, but I am from the school of Saint Thomas and prefer, when it comes to these things, to see before believing” (SOUSA, Marcelo Rebelo, The Gospels, 2001, Lisbon, publisher by Editora Bertrand, 2001]. This study was carried out, for the primary purpose of the exhaust concentration of gases inside visit boxes, but mainly, shows that its appearance and respective concentration, varies and occurs without warning! Without the correct use of personal protective equipment, work inside visit boxes is dangerous. If necessary, reinforce constant information and training on the use of personal protective equipment and collective. This work intends to initiate a historical record of measurements of hydrogen sulfide present inside visit boxes. With the results of measurements, intends to take a “Radiography Photo” to the sewerage systems. With the final results of this study, intended to demonstrate clearly and objectively, imminent dangers causes by exposure to high concentrations of hydrogen sulfide gas.
