The word asbestos is first used in the 1600s which derives from the Ancient Greek meaning "unquenchable" or "inextinguishable" [1]. Asbestos was first used in the yarn manufacturing, and Louis Wertheim, a German industrialist adopted this process in his factories in Germany [2]. About 33 large - scale asbestos manufacturing
