This brochure provides information on silicosis for construction workers. Topics discussed include early deaths from dust exposure, symptoms of silicosis, exposure to silica (14808607), activities during which silica dust may be present, prevention of silicosis, medical examinations for exposed workers, and sources of additional information. Construction workers may be exposed to silica dust through their work with building materials. Abrasive blasting, chipping, hammering, drilling, sawing, grinding, crushing, loading, hauling, dumping, demolishing, and dry sweeping are activities which allow the dust to enter the air. The use of dust control systems during drilling and sawing can reduce dust exposures. Local exhaust ventilation is important; good work practices also reduce much of the exposure. Abrasives containing less than 1% crystalline silica should be used during abrasive blasting to prevent harmful quartz dust from being released. Respirators should only be used until adequate dust control measures are in place and should never be the primary method of protection.
