Most recently, the railroad industry has been faced with litigation arising from allegations of low-dose and cumulative exposures to diesel exhaust in shops and on-board locomotives. Various studies have suggested that these exposures can cause COPD (obstructive lung disease), asthma or reactive airways disease (a.k.a. diesel asthma), cognitive dysfunction (a.k.a. diesel encephalopathy), and/or any number of cancers (lung, stomach, kidney, larynx, brain, or colon). Additionally, some studies have proposed that diesel exhaust exposure can trigger cardiovascular disease. As these lawsuits have increased, Gallagher Sharp’s attorneys have been at the forefront developing defense strategies and retaining expert witnesses to defend these allegations. Our attorneys are well-versed in peer-reviewed literature and can provide epidemiological and causation defenses on the failure of these studies to prove such relationships. Gallagher Sharp defends and/or assists in the defense of diesel exhaust cases in Ohio, Michigan, Illinois and Tennessee.
