Are Oil Refinery Workers at Risk for Mesothelioma?
Yes. Oil refinery workers face substantial mesothelioma risk due to the widespread use of asbestos insulation on pipes, vessels, heat exchangers, and equipment throughout petroleum refineries. The high-temperature processes involved in oil refining required extensive thermal insulation, and asbestos was the material of choice for decades.
Asbestos in Oil Refineries
Petroleum refineries process crude oil at extreme temperatures and pressures, requiring extensive thermal insulation throughout the facility. For most of the 20th century, asbestos was the primary insulating material used on pipes, process vessels, heat exchangers, distillation columns, storage tanks, valves, and flanges. A large refinery could contain thousands of tons of asbestos-containing insulation and materials.
Oil refinery workers in every trade were exposed to these materials. Insulators applied and maintained asbestos lagging. Pipefitters worked around insulated piping systems. Boilermakers maintained vessels wrapped in asbestos. Operators monitored equipment surrounded by asbestos insulation. Even general laborers who cleaned work areas and handled debris encountered asbestos fibers regularly.
Turnaround and Maintenance Exposure
The most intense asbestos exposures in refineries occurred during scheduled maintenance shutdowns, known as turnarounds. During these events — which could last several weeks — workers stripped old asbestos insulation from equipment to access it for inspection, repair, or replacement. After maintenance was complete, new insulation was installed. The stripping process generated massive quantities of airborne asbestos fibers in the outdoor and semi-enclosed work areas of the refinery.
Turnarounds employed hundreds or even thousands of workers simultaneously, many of them contract workers from insulation and maintenance companies. These workers often moved from refinery to refinery, accumulating exposures across multiple facilities and multiple employers over their careers.
Gulf Coast refineries in Texas, Louisiana, and Mississippi employed particularly large workforces and used vast quantities of asbestos materials. Workers in these facilities have been disproportionately affected by mesothelioma and other asbestos-related diseases.
Health Monitoring
Current and former refinery workers should maintain awareness of their asbestos exposure history and communicate it to their healthcare providers. The long latency period of mesothelioma means that workers exposed in the 1960s through 1980s may still be at risk for developing the disease today. Regular chest imaging and pulmonary function monitoring can aid in early detection.
Legal Rights and Compensation
Refinery workers diagnosed with mesothelioma have strong legal claims against the manufacturers and suppliers of asbestos insulation and other products used in the refineries where they worked. Compensation may be available through product liability lawsuits, asbestos trust funds, and workers’ compensation claims. An experienced attorney can investigate your work history and pursue all available avenues of recovery at no upfront cost.
- Asbestos locations: Pipe insulation, vessel lagging, gaskets, refractory materials, and heat exchangers
- Turnaround exposure: Scheduled maintenance shutdowns involved stripping and replacing asbestos insulation
- Texas refineries: Gulf Coast refineries employed hundreds of thousands of workers exposed to asbestos
- Multiple trades: Insulators, pipefitters, boilermakers, operators, and laborers were all at risk
