There are many ways we’ve developed evidence to show asbestos insulation was on all steam engines, diesel/freight engines, was a component of brake shoes for many years, was an insulating material on cabooses, and that asbestos insulation was used in many yard offices or buildings including the old round houses. There are industrial hygiene/industrial safety experts that also understand where asbestos was located. Furthermore, there are times when we must refer our clients to medical doctors with experience with asbestos exposures and have to determine whether certain lung diseases are connected to asbestos for example. And, in cases of lung cancer, mesothelioma and other cancers, we are always seeking out the top professionals in order to make analysis.
