As the mining and manufacturing of asbestos exploded, so did its dangerous health effects on those who mined and refined the mineral, as well as those who worked with it. Asbestos' resistance to chemicals, heat, water and electricity made it an excellent insulator for the steam engines, turbines, boilers, ovens and electrical generators that powered the Industrial Revolution.
