Nelson, D. v. Airco Welders Supply
107 A.3d 146
Pa. Super. Ct.2014Background
- James Nelson, a long‑time steelworker and welder, developed mesothelioma and sued multiple manufacturers alleging asbestos exposure from welding rods (Hobart, Lincoln) and Crane Co.’s asbestos sheet gasket (“Cranite”); verdict for plaintiff: $14.5 million.
- Trial used reverse bifurcation (liability first), consolidated with other mesothelioma cases; Nelson’s sole causation expert at liability phase was Dr. Daniel DuPont.
- Dr. DuPont testified mesothelioma results from "significant" asbestos exposure and endorsed that any exposure above ambient ("no innocent fibers") is a substantial contributing factor; he conceded he could not quantify incremental exposures or prove which specific product "did it."
- Defense experts disputed release of respirable fibers from encapsulated flux in welding rods and testified about destruction of fibers by welding temperatures; Crane presented experts distinguishing chrysotile (Cranite) from more toxic amphiboles and disputing significant exposure from Cranite.
- Jury found products defective and awarded damages; defendants appealed arguing (inter alia) that Dr. DuPont’s "any‑exposure" causation was inadmissible under Pennsylvania law, that evidence of exposure to respirable fibers was insufficient, Crane’s product was not used as intended, and plaintiff counsel’s damages argument was improper.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of expert causation ("any‑exposure" theory) | DuPont testified that "significant" exposures (visible dust, above ambient) are substantial causes and therefore his testimony supports causation. | Appellants argued any‑exposure testimony is scientifically and legally insufficient under Betz/Gregg and should be excluded; urged JNOV or new trial. | Court held Dr. DuPont’s testimony tracked the disfavored any‑exposure theory (each incremental exposure is substantial) and was inadmissible; liability verdict vacated and new trial ordered. |
| Sufficiency of evidence that defendants’ products released respirable asbestos fibers | Nelson relied on lay testimony about visible dust from products and Dr. DuPont’s hypothetical linking visible dust to respirable fibers. | Defendants presented technical and industrial testimony that encapsulated flux and high welding temperatures prevented release or destroyed fibers; argued plaintiff failed frequency/regularity/proximity proof. | Court declined to resolve sufficiency on the record and remanded for a new trial where parties may present a different evidentiary record. |
| Crane Co. — intended use / intended user for strict liability and failure to warn | Nelson argued Cranite was distributed in sheet form and required user cutting (an intermediate step), so Nelson’s cutting/use could be an intended use and Crane owed a warning to such users. | Crane contended Cranite’s intended use was gasket sealing (not welding shields) and Nelson was not an intended user; asked for exclusion on that ground. | Court held the intended‑use doctrine applies to failure‑to‑warn claims; factual questions about whether Nelson’s use was within intended use must be decided by jury on remand and Crane may present its evidence. |
| Improper remarks in damages phase (suggesting specific amounts / formula) | Nelson’s counsel argued non‑economic damages were "infinitely more" than stipulated economic damages and suggested starting at $1 million and adding amounts for multiple elements. | Defendants objected that counsel suggested a specific formula/amounts, referenced settlements, and improperly appealed to passion/punitive considerations; sought mistrial/new trial. | Court found counsel’s formulaic suggestion and repeated $1 million prompt inappropriate and prejudicial; failure to give a curative instruction was an abuse of discretion; damages verdict vacated and new trial on damages ordered. |
