These individual efforts, costly and often duplicative, lead to the formation, in December of 1970, of the Asbestos Information Associ ation/North America: a group of asbestos companies in the United States and Canada working together for the com mon interest of a vital industry challenged by relatively new and often confusing information concerning asbestos and health.
