SOUD, J. Appellant Priscilla Lewis brought a wrongful death action against Appellee Norfolk Southern Railway Company under the Federal Employers’ Liability Act, 45 U.S.C. §§ 51 et seq., claiming that her husband Clarence Lewis died from chronic lymphocytic leukemia caused by occupational exposure to diesel exhaust during his 39-year career as a railroader. The trial court ultimately entered summary judgment in favor of Norfolk after excluding the testimony of Lewis’s liability expert under Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579 (1993).

Mrs. Lewis appeals the summary judgment and argues the trial court erred in its conclusion that her liability expert’s testimony did not satisfy Daubert’s requirements. We have jurisdiction. See Art. V, § 4(b)(1), Fla. Const.; Fla. R. App. P. 9.030(b)(1)(A). We reverse the summary judgment and remand the case to the trial court for further proceedings, concluding the expert’s testimony was admissible under Daubert, thus precluding summary final judgment.

I.

Mr. Lewis worked for Norfolk from May 1975 until June 2014, working primarily out of the Simpson Yard in Jacksonville, Florida. 1 At various points, Mr. Lewis worked as a coal laborer, switchman, conductor, and engineer. According to his wife, Mr. Lewis worked mainly as an engineer. The record before us describes a demanding job—one that involved working near running engines and other diesel-powered machinery while switching cars, building trains, and operating trains locally. Mrs. Lewis presented evidence that in this work, Mr. Lewis was exposed to diesel exhaust daily, often returning home with diesel fuel and soot on his clothes and in his hair.

Coworkers testified in depositions that diesel spills in the yard also were not uncommon. One coworker, Bobby Jamison, testified that Mr. Lewis was taken to a local hospital after one particular

2 chemical spill, after which Mr. Lewis suffered from a severe cough “for years.” Further, another coworker testified that employees never received any warning about risks associated with exposure to diesel exhaust.

In 2011, at 57 years of age, Mr. Lewis was diagnosed with chronic lymphocytic leukemia, a form of cancer. His treatment regimen required he retire from Norfolk in the summer of 2014. Just three months after retiring, in September, Mr. Lewis died.

In 2017, Mrs. Lewis, as the personal representative of her husband’s estate, filed a FELA wrongful death action against Norfolk. She alleged Norfolk was negligent in causing Mr. Lewis’s long-term exposure to known carcinogens—diesel exhaust and benzene, a component of diesel exhaust—throughout his employment. She further claimed Norfolk was negligent by failing to provide a reasonably safe workplace by failing to take certain protective measures and by failing to warn of the risk of cancer when exposed to diesel exhaust and benzene, a component of diesel exhaust.

To support her cause of action, Mrs. Lewis designated two experts: Dr. Paul Rosenfeld, as a liability expert, and Dr. Mark Levin, as her medical expert on causation. Pertinent here, Dr. Rosenfeld opined that the railroad industry has known since the 1950s that diesel exhaust is a human carcinogen. He cited evidence linking its exposure to increased cancer risk, particularly among railroad workers. Considering these recognized risks, numerous agencies and industry groups recommend protective measures such as respirators and air-conditioned cabs.

Nevertheless, Dr. Rosenfeld says that despite knowing diesel exhaust exposure’s carcinogenicity since 1955 and industry and government findings, Norfolk did not adopt any internal policy about it until 2006, in which it claimed to its employees in a “Diesel Information Sheet” that there is a “lack of evidence of chronic, non- cancer health effects at occupational exposure levels” and “[t]here also remains a question in the scientific community as to whether diesel exhaust causes lung cancer.”

Based upon the Environmental Protection Agency’s Superfund Risk Assessment tool, Dr. Rosenfeld further opined that

3 Mr. Lewis was subjected to long-term exposure to significant, above-background levels of benzene from locomotive diesel exhaust emissions, which placed Mr. Lewis at a substantially elevated risk of getting cancer. In forming this opinion, Dr. Rosenfeld quantified the “inhalation unit risk factor” by calculating the ambient diesel particulate matter (“DPM”) concentration in the occupational environment. According to Dr. Rosenfeld, DPM is “used as a surrogate measure of exposure to whole diesel exhaust.” Dr. Rosenfeld did note that his assessment considered potential liability based on exposure and did not determine the specific risk of contracting chronic lymphocytic leukemia.

Dr. Rosenfeld ultimately concluded that Norfolk did not meet a reasonable standard of care throughout Mr. Lewis’s career. More specifically, Norfolk failed to: (i) provide a reasonably safe place to work; (ii) warn of the health risks associated with exposure to diesel exhaust and benzene; (iii) implement controls to minimize diesel exhaust; (iv) comply with the Federal Locomotive Inspection Act and OHSA standards; and (v) provide air monitoring/exposure monitoring.

Norfolk moved to exclude Dr. Rosenfeld’s testimony, arguing that his methodology of converting elemental carbon (“EC”) to DPM was unreliable because it is untested and has not been subjected to peer review or publication. Specifically, Norfolk argued below, as it does here, that the generally accepted method for calculating diesel exhaust exposure is by measuring EC and comparing that measurement to exposure guidelines. Dr. Rosenfeld’s methodology of converting the EC levels to DPM was unreliable because he “took the elemental carbon number from various studies he looked at from other railroads, [and] convert[ing] it to diesel particulate matters[,] [h]e’s basically doing the opposite or going backwards.” Further, Norfolk argues that literature provides no consensus for rates of conversion for Dr. Rosenfeld’s conversion method.

Norfolk also argues that Dr. Rosenfeld’s analysis was not reliably applied to the facts in this case because he: (a) utilized an EPA Superfund Risk Assessment tool meant for Superfund sites

4 and not railyards; and (b) his data and assessment tools related to risks of lung cancer rather than chronic lymphocytic leukemia.

The learned and conscientious trial judge granted Norfolk’s motion, concluding that Dr. Rosenfeld’s testimony must be excluded under Daubert. In its written order, the trial court determined that Dr.
