Asbestos in American Schools: The Buildings That Exposed a Generation

An estimated 107,000 US school buildings still contain asbestos. Most were built before 1980. The students who attended those schools are now in their fifties and sixties — entering the window when asbestos-related disease, with its 20-50 year latency period, begins to appear. Teachers and custodial workers who spent careers in those buildings face elevated risk. The mesothelioma diagnoses being made in this age group today are, in part, the product of asbestos installed in American schools during the post-war building boom.

This investigation documents how it got there, why it’s still there, and what legal rights the people affected have today.

The Post-War School Building Boom

Between 1950 and 1975, hundreds of thousands of new school buildings were constructed across the country to accommodate the baby boom generation. These buildings used the materials of their era — and their era’s primary fireproofing and insulation material was asbestos. Ceiling tiles from Armstrong World Industries and Celotex Corporation, floor tiles, pipe insulation from Johns-Manville, spray-applied fireproofing from W.R. Grace’s Monokote product line — asbestos was present in the typical school building in multiple forms, in multiple locations.

The EPA has estimated that approximately 107,000 US schools contain asbestos-containing materials. An estimated 15 million students and 1.5 million employees were exposed to asbestos in school environments during the peak exposure decades.

The Exposure Pathways

Not all asbestos in school buildings poses equal risk. Intact, undisturbed asbestos-containing materials typically do not release fibres at dangerous concentrations. The risk comes from disturbance — and schools are environments of constant disturbance. Ceiling tiles in older buildings are routinely displaced. Floor tiles crack and chip. Pipe insulation in boiler rooms deteriorates over time. Renovation and repair projects disturb materials that were safe when undisturbed.

Building maintenance workers are the group at highest risk: custodians and maintenance staff who work in boiler rooms and utility spaces, and who perform the repair and renovation work that disturbs asbestos-containing materials. This group has documented elevated rates of asbestos-related disease that is only now becoming fully apparent as the latency period matures.

AHERA and Its Limits

Congress passed the Asbestos Hazard Emergency Response Act in 1986, requiring school districts to inspect for asbestos, develop management plans, and notify parents and employees. AHERA was significant — but it required management, not removal. Asbestos in good condition could stay in place under an approved management plan.

Forty years after AHERA’s passage, the majority of the asbestos installed in American school buildings during the post-war construction boom is still there. It is managed. It is monitored. But it has not been removed. Every year that it remains, maintenance workers and renovation contractors face exposure risk.

The Trust Fund Connection

Teachers, school administrators, and building maintenance workers who developed mesothelioma as a result of school-environment asbestos exposure may have trust fund claims against the manufacturers of the specific products in their buildings. Armstrong World Industries, Celotex, Johns-Manville, and W.R. Grace all established bankruptcy trusts that cover school-environment exposures. Identifying the specific products in a specific building — a requirement for trust fund claims — is the work of experienced mesothelioma attorneys with access to building records, construction archives, and product databases.
