Ebenhoech v. Koppers Industries, Inc. (2002)
According to Quimbee, Albert Ebenhoech (plaintiff) slipped and fell 15 feet off the side of a train tank car, severely injuring his leg. Ebenhoech was working as chief chemical operator at Solutia, Inc., at the time of the accident. Ebenhoech sued Koppers Industries, Inc. (Koppers) (defendant) for spilling a chemical on the car and not cleaning it off before shipping it to Solutia. After the accident, Solutia created an incident report stating the chronology of the incident and claiming the primary cause was Ebenhoech working without full protection. Koppers attempted to admit the report into evidence as part of its defense. Ebenhoech objected, arguing that the report was inadmissible hearsay.

Appellees are each administrators of the estates of their deceased husbands, who had been employed by Bethlehem[2] as coke oven workers. Appellees commenced these actions on December 13, 1977.

The causes of action were grounded in negligence, strict liability in tort and breach of warranty and were based upon alleged defects in the coke ovens. It was revealed during discovery that all decedents had died more than two years before the actions were brought. In fact, the instant litigation was instituted more than five years after the most recent death.
