Kentucky Trades & Asbestos Exposure
Kentucky's union construction trades and industrial workers handled, installed, removed, and worked alongside asbestos-containing materials on virtually every major industrial project from the 1930s through the 1980s. The trade you worked — and the specific tasks you performed during normal duty — determines which asbestos products you encountered and which manufacturers may be responsible. Below: documented exposure pathways per trade, drawn from public litigation records, OSHA inspection histories, and industrial hygiene literature.
Trade tasks listed below describe job functions documented in public records as routes of asbestos exposure for workers in these crafts. They are general exposure pathways, not claims about any individual worker's case.
