When did they stop using asbestos in buildings? Quick Answer. The first asbestos ban in the United States occurred in 1977 but was limited to very specific uses of the substance. In 1989, the federal government banned virtually all use and manufacture of asbestos in the country, including its use in building materials.
These desirable properties made asbestos a very widely used material, and its use continued to grow throughout most of the 20th century until the knowledge of carcinogenic effects of asbestos dust caused its effective demise as a mainstream construction and fireproofing material in most countries.mphiboles including amosite (brown asbestos) and crocidolite (blue asbestos) were formerly used in many products until the early 1980s. Tremolite asbestos constituted a contaminant of many if not all naturally occurring chrysotile deposits.
