Agricultural Grain Dryers & Farm Heating Equipment — Asbestos Exposure Crosswalk

What This Equipment Is

Modern agriculture depends on a substantial set of heated equipment that historically used asbestos materials:

  • Commercial grain-elevator drying systems — large fan-and-burner units drying truck-loaded grain at country and terminal elevators
  • On-farm continuous-flow grain dryers — Sukup, GSI, Brock, Hutchinson, Mathews, MFS, and other OEM dryer brands
  • Crop-drying batch bins — drying crops in storage bins
  • Livestock-barn heating — radiant tube heaters, hot-water heating systems
  • Greenhouse and nursery heating — boilers, distribution piping, radiant heating
  • Tobacco-curing barns — heated air systems for tobacco curing
  • Hop and malt kilns (see Malt Kilns)
  • Sugar-refining and processing equipment

These heat sources, ductwork, and surrounding piping historically used asbestos-bearing insulation, gaskets, and packing through the late 1970s.

Why Agricultural Heating Equipment Was an Asbestos Exposure Pathway

Farmers and farm workers performed their own equipment maintenance on grain dryers, livestock-barn heaters, and processing equipment — repairing burners, replacing chamber-insulation patches, servicing fan-motor and heating-element components. Each repair event disturbed asbestos at close range, often in poorly ventilated farm-shop or barn environments.

Commercial-grain-elevator workers performing major dryer maintenance, fan-rebuild, and ductwork repair on the larger-scale elevator drying systems encountered the same exposure pathways at industrial scale.

Tobacco-curing barn workers — including farm families and seasonal contract workers — operated and maintained asbestos-bearing curing equipment continuously during the curing season.
