In which year was spray-applied and TSI application/installation of asbestos banned?

The ban on the spray-applied and thermal spray insulation (TSI) application and installation of asbestos occurred in 1978, which is critical in understanding the regulatory framework surrounding asbestos use. This year marked a significant step in public health policy as it acknowledged the hazardous effects of asbestos exposure and aimed to protect workers and the general population from the associated health risks, such as asbestosis, lung cancer, and mesothelioma. The decision to implement this ban was informed by increasing evidence of the dangers of asbestos, leading to more stringent regulations in subsequent years regarding its use in various applications.
