Overview
Ironworkers — tradespeople who erect structural steel, install reinforcing bars, and work on metal construction — faced significant asbestos exposure from fireproofing materials, welding products, and structural insulation. Asbestos spray-on fireproofing was standard for protecting steel structures from fire.
Asbestos in Ironwork
| Product | Application | Exposure Level |
|---|---|---|
| Spray-on fireproofing | Structural steel protection | Very High |
| Welding blankets | Fire protection during welding | High |
| Fireproof coatings | Steel beam protection | High |
| Deck insulation | Metal deck assemblies | Moderate |
How Ironworkers Were Exposed
Fireproofing Exposure
Asbestos spray-on fireproofing was applied to structural steel:
- Ironworkers worked while fireproofing was being applied nearby
- Overspray contaminated entire work areas
- Fibers remained airborne in enclosed buildings
- Touch-up work disturbed dried fireproofing
Welding Operations
Ironworkers performed extensive welding:
- Used asbestos welding blankets for fire protection
- Cut through steel with asbestos coatings
- Worked with asbestos heat shields
Even ironworkers who didn’t directly handle asbestos products were heavily exposed when spray fireproofing was being applied to steel structures they were erecting.
Work Environments
Ironworkers faced exposure in:
- High-rise construction: Office buildings, hotels
- Industrial facilities: Factories, power plants
- Shipyards: Ship structural work
- Bridges and infrastructure: Structural steel projects
- Renovation and demolition: Disturbing existing structures
Related Occupations
Ironworkers worked alongside:
- Welders — Structural welding
- Carpenters — Building construction
- Laborers — General assistance
- Operating engineers — Equipment operation
- Boilermakers — Industrial structures

Health Consequences
Ironworkers are at elevated risk for:
- Mesothelioma: Cancer of the chest or abdominal lining
- Asbestosis: Progressive lung scarring
- Lung cancer: Especially combined with smoking
- Pleural disease: Thickening of lung lining
Legal Options
Ironworkers diagnosed with mesothelioma may pursue:
Asbestos Trust Funds
Fireproofing and building material manufacturers have established trusts.
Additional Claims
- Product liability lawsuits: Against fireproofing manufacturers
- Premises liability: Against building owners
- General contractor liability: Against contractors
- Workers’ compensation: Through employer coverage
