New Directions in Dust Control Concrete Construction

Over the long term, construction dust exposure can lead to chronic bronchitis, emphysema, or silicosis, a severely disabling and often fatal lung disease. Some studies suggest a link between crystalline silica inhalation and lung cancer. Personal protective equipment can reduce exposure, as long as equipment is chosen, fitted, and used properly.
