Asbestos Exposure in School Environments
Asbestos has been a notable concern in school buildings, primarily due to its prevalence in construction products. This has led to exposure risks for millions of students and staff.
Historical Context of Asbestos in Schools
Before 1980, asbestos was commonly used in various building materials, coinciding with a period (1950-1969) when nearly half of all U.S. primary and secondary school buildings were constructed. At the time, asbestos use was at its peak. Following increasing awareness and regulation in the 1970s, the use of asbestos in new constructions significantly decreased in the 1980s.
Current State of Asbestos in Schools
Despite regulations, the average age of U.S. schools, approximately 44 years, means many still contain aging asbestos materials. These materials, if deteriorating, can release harmful fibers. An Environmental Protection Agency (EPA) survey in 1984 estimated that about 15 million students and 1.4 million teachers and staff across almost 35,000 schools were at risk of asbestos exposure
Common Asbestos-Containing Products in Schools
Asbestos was used in schools for its heat resistance and durability. Common applications included:
- Acoustic panels and asbestos boards
- Asbestos cloth and sprays
- Asbestos tiles (floor, wall, ceiling)
- Boilers and duct insulation
- Fireproofing materials and gaskets
- Heating systems and popcorn ceilings
- Sheetrock and school supplies (like crayons)
- Wiring insulation
Asbestos Exposure Risks in Schools
Exposure to asbestos in schools remains a health and financial concern. The true extent of asbestos hazards in U.S. schools is largely unknown
Who Faces Exposure Risks in Schools?
Asbestos exposure in schools potentially affects various groups, including:
- Students, who are more likely to inhale fibers due to their active nature and time spent on the floor
- Teachers, with mesothelioma rates comparable to high-risk occupations
- Other school employees like maintenance workers and janitors, particularly in older facilities with asbestos materials
The Ongoing Concern of Asbestos in Schools
While efforts have been made to regulate and reduce asbestos use, the presence of asbestos in older buildings poses ongoing risks. Awareness and proper management of asbestos-containing materials are essential to minimize exposure and safeguard health.
