The incidence of pleural fibrosis among school maintenance and custodial workers was studied. Chest radiographs and demographic, employment, and exposure histories were reviewed and analyzed statistically from 457 school maintenance and custodial workers. Radiographs were evaluated by two B-readers. Abnormalities consistent with asbestos caused disease were recognized in 29 radiographs; 26 radiographs showed pleural abnormalities. An association was seen between the presence of radiographic abnormalities and length of school employment as well as between profusion of irregular opacities and increasing mean years of employment. Laborers and maintenance workers had the highest prevalence of radiographic changes among the group of workers who had been employed in schools for more than 20 years; while laborers and building service workers had the highest abnormality prevalence rate among those with less than 20 years of employment. School buildings had friable and nonfriable asbestos (1332214) containing materials. The authors conclude that custodial and school maintenance workers are at risk of developing asbestos related disease.
