Maryland’s industrial heritage is centered on Baltimore’s steel and shipbuilding complex. Bethlehem Steel’s Sparrows Point plant — once the largest integrated steel mill in the world — employed tens of thousands of workers surrounded by asbestos-laden insulation, pipe lagging, and fireproofing for most of the 20th century.

Maryland asbestos cases are concentrated in Baltimore City Circuit Court, which maintains an active asbestos litigation docket. Maryland applies a discovery rule, so the 3-year window does not begin until a confirmed mesothelioma diagnosis is received.
