Wyoming, as one of the states that plays host to a significant portion of the Rocky Mountains has a fairly high amount of naturally occurring asbestos as a result. The location of this asbestos risk is in a mineral called “serpentine”, which has been linked to asbestos related death. However, due to the sheer vastness of this State and it’s very low population in relation to its size most of the general population is well out of harm’s way.

Asbestos and Mesothelioma Related Deaths in Wyoming

There have been some reported cases of asbestos exposure in this State albeit most of which have come as a result of the oil-refining industry. Four main oil producers operate refineries in Wyoming; Standard, Sinclair, Texaco, and Stouffer. Also, the United States Navy has had drilling and refining operations here in the past.

In spite of all these apparent risks Wyoming remains to be the lowest across the country in asbestos related fatalities. Approximately seventy cases have been reported in the last twenty or some odd years which is hundreds below the national average. With that being said cases of mesothelioma account for nearly half of all of those reported so a certain amount of precaution would still be advisable.
