Which Trades Had the Highest Asbestos Exposure in Indiana?

Insulators (Heat & Frost)

The highest-risk trade. Insulators applied, removed, and repaired asbestos pipe covering, block insulation, and boiler lagging on virtually every industrial project. Fiber concentrations during pipe stripping regularly exceeded OSHA PELs by 10–100×.

Highest RiskHFIA

Boilermakers

Boilermakers built, repaired, and overhauled power plant boilers, industrial furnaces, and pressure vessels — all insulated with asbestos block and cement. Annual shutdown work at power plants created recurring high-exposure events throughout a boilermaker's career.

High RiskIBB

Pipefitters & Steamfitters

Pipefitters installed and maintained steam, process, and utility piping throughout industrial facilities. Working alongside insulators on every project, they disturbed asbestos pipe covering daily and were exposed to airborne fibers from neighboring trades' work throughout their careers.

High RiskUA

Electricians (IBEW)

Electricians worked in environments saturated with asbestos from adjacent trades, ran wiring through asbestos-insulated conduit, and worked alongside insulated electrical equipment at power plants, substations, and industrial facilities. Electrical panels and switchgear also used asbestos arc-suppression components.

High RiskIBEW

Ironworkers

Ironworkers erected structural steel in facilities where asbestos fireproofing was sprayed on structural members during construction. They were directly exposed during application and worked continuously in buildings where sprayed fireproofing remained in place for decades.

High RiskIronworkers

Carpenters

Carpenters worked in buildings throughout the construction and renovation era, disturbing asbestos floor tiles, ceiling tiles, joint compound (drywall mud), and insulated building components. Bystander exposure from other trades was also significant.

Moderate RiskUBC

Sheet Metal Workers

Sheet metal workers fabricated and installed HVAC duct systems lined with asbestos insulation board, and worked in boiler rooms alongside insulators. Cutting, bending, and fitting asbestos-insulated ductwork generated fiber clouds in confined mechanical spaces.

Moderate RiskSMWIA

Steelworkers (USW)

Steelworkers in Indiana's steel mills and basic metals industry faced asbestos refractory exposure at blast furnaces, coke ovens, and electric arc furnaces, plus asbestos gaskets throughout high-temperature process equipment.

Indiana Filing Deadline for Trade Workers
Indiana gives asbestos disease victims two years from diagnosis to file under Ind. Code § 34-20-3-1. Union members frequently work at dozens of jobsites across their careers — your full work history matters. Contact a Indiana asbestos attorney to document every facility before the deadline.
