Because it was cheap and versatile, asbestos was considered a miraculous, indestructible substance with powerful wartime applications, and used in Navy ships since the mid-1930s. The major application has been as an insulating material around steam boilers and as insulating lagging wrapped around steam and hot water piping. It is this thermal insulation material that has the greatest potential for concentrations of asbestos fibers in the air when seriously damaged or removed.
