 The Environmental Protection Agency, created in 1970, became the crusader. In 1973, it banned spray-on asbestos for insulating and fireproofing purposes. The 70s would also see them ban asbestos in cement pipes, artificial fire embers, and wall-patching compounds. In the 80s, it required schools to document asbestos and remove it if dangerous to protect children and teachers, though the cost of abatement was sometimes prohibitive.
