Silicosis is a debilitating lung disease caused by inhalation of crystalline silica.
This report summarizes the results of the survey conducted in response to this request, which identified eight workers with radiographic evidence of pneumoconiosis and indicated that inappropriate selection and use of respirators during abrasive blasting operations were common. The objectives of the survey were to identify workers with silicosis and to assess the workers' knowledge about proper use of respiratory protection and appropriate industrial hygiene practices for the prevention of exposures to silica. Participants were recruited from the membership rosters of a trade union, through the Cleveland office of the ODH, and through media advertisements. Screening consisted of a work history, a medical questionnaire, and a chest radiograph. Occupational questions focused on the intensity and characteristics of exposures to silica.
