What aspect of health and safety does the AHERA primarily focus on?

The AHERA, or the Asbestos Hazard Emergency Response Act, specifically focuses on asbestos exposure in school settings. This legislation was enacted to protect the health and safety of students and staff by mandating that schools conduct inspections for asbestos-containing materials and develop management plans to address any identified hazards. The intent is to ensure that schools minimize risks related to asbestos exposure, which can lead to serious health issues such as asbestosis, lung cancer, and mesothelioma.

In the context of the other options, while asbestos use in industrial settings, asbestos levels in residential buildings, and the management of asbestos in commercial properties are all important health and safety concerns, they are not the primary focus of AHERA. This act is specifically aimed at ensuring safe environments for school-aged children and personnel, thus addressing the unique risk factors associated with school environments.
