Asbestos in Vermont schools: findings of a statewide on-site investigation.

Materials containing asbestos were found in 75 per cent of 336 Vermont Schools constructed or renovated between 1946 and 1974, with two-fifths of the materials in student exposure areas. Findings from visits to all schools contrasted with an earlier investigation relying on self-reporting. Of 105 schools with student exposure disclosed by the current survey, only eight had been identified in the earlier effort. Ceiling tiles, previously not believed to contain substantial asbestos material, constituted a source of student exposure in 36 schools.
