Filmes históricos

Vejam este excelente filme, publicado no Google Vídeo.
Stop Silicosis: Filme de 1938 que aborda o flagelo da silicose. Da autoria do US Department of Labor destina-se a prevenir esta fatídica doença ocupacional.
In 1938, the US Department of Labor released this film aimed at preventing the occupational disease of silicosis. That overexposure to silica dust caused this deadly disease had been known for more than 100 years, but many employers ignored workplace dust control methods. Sadly, almost 70 years later, hundreds of workers each year still develop this preventable lung disease. The current OSHA exposure limit for silica dust is based on science from the mid 1960s. Most of the information and prevention measures in this film are still relevant today.
Asbestos A Matter of Time: Um outro excelente filme foi criado em 1959, pelo US Department of Mines e é sobre o amianto. Muitas das coisas que aborda continuam, infelizmente, muito actuais. Quase 50 anos depois!!!

This 1959 film by the Bureau of Mines (US Department of the Interior.) describes how asbestos is mined and processed and the significant role it plays in our lives. Using diagrams and on location shooting, both open pit and block carving methods of mining asbestos are described, followed by a detailed examination of how the fiber is milled and undergoes its change from crude ore to refined fiber. The remainder of the film deals with the numerous ways this versatile mineral enhances our daily lives, from roofing materials to automobile brake linings. Note several mentions of dust control, but no specific mention of the occupational asbestosis, lung cancer or mesothelioma, diseases caused by inhaling asbestos dust. Asbestos manufacturers knew of these diseases by the 1930s. For more information, go to the Asbestos Disease Awareness Organization (ADAO) website.
Mais uma vez, ambas as referências chegaram-me através da Safety List. É um extraordinário recurso. Num próximo post, publicarei mais 2 filmes.
