Wyoming is known for its wide open spaces, cattle ranches, and breathtaking mountains, and it is a predominately rural and agricultural state.  As you might expect, Wyoming residents were less likely to be exposed to asbestos than residents of more heavily industrialized states.

However, asbestos was still widely used in the Cowboy State. Wyoming has numerous oil refineries, chemical plants, and electrical power plants. At least until the 1980s, these industrial facilities used large amounts of asbestos insulation on their machinery, boilers, and steam lines.

Asbestos was also a common ingredient of many construction materials. Builders used asbestos insulation as a barrier against Wyoming’s long cold winters. Asbestos pipe-covering was used on water lines, and asbestos insulation, gaskets, and packing were used on residential and commercial boilers.  Asbestos was also used in cement, plaster, drywall joint compound, shingles, siding, floor tile, and many other building products.


Below is a list of occupations that put Wyoming workers at a known risk of asbestos exposure. If you worked in one of these occupations in the 1980s or earlier, there is a good chance that you were exposed to asbestos:

  • Automobile Mechanics
  • Boilermakers
  • Chemical Plant Workers
  • Construction Workers
  • Electricians
  • Insulators
  • Oil Refinery Workers
  • Pipefitters
  • Plasterers
  • Power Plant Workers
  • Railroad Workers
  • Sheetmetal Workers
  • Welders


There are many Wyoming job sites with a documented history of asbestos use. Some of these sites are listed below. Asbestos was used at these sites, and many others in Wyoming.

If you or a family member worked in one of these places, or if you believe that you may have been exposed to asbestos at your own job, please contact one of our mesothelioma attorneys for more information. The sites include:

Fortunately for Wyoming residents, the state has relatively low incidence of mesothelioma and other asbestos disease, due to its small population and relatively low use of asbestos.

The Centers for Disease Control have reported 44 mesothelioma deaths in Wyoming in the years 1999 to 2005 alone. Although this is lower than most other states, it is still far too high.

Moreover, mesothelioma has a long latency period. It usually takes anywhere from 10 to 50 years to develop mesothelioma after the initial exposure to asbestos. Thus, Wyoming residents may be diagnosed with mesothelioma well into the twenty-first century, although asbestos is rarely used today.
