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.
