Danny Long v. Quad Power Products, LLC
Danny Long suffered a severe arm injury, leading to amputation, when a ball valve mechanism broke while he was pressure testing. He and his wife, Geraldine Long, filed a product liability complaint against four companies, alleging negligence and failure to warn. Mr. Long's employer, Alstom Power, Inc., joined as an intervening plaintiff. After Mr. Long's death, Ms. Long continued the suit. The case eventually narrowed to a strict liability claim against Southern Fluidpower, Inc., based on failure to warn about pressure capacity and corrosion in water systems. The trial court granted summary judgment for Southern Fluidpower, finding no genuine issue of material fact that Southern's alleged failure to warn caused Mr. Long's injury, attributing the cause in fact to Alstom's negligence in assembling and using a known faulty valve. The Court of Appeals affirmed the summary judgment, agreeing that Alstom's actions were an intervening cause.
