A recent Court of Appeals case illustrates that trying to make a Tennessee product liability claim against a product that did not technically cause the injury can be quite difficult. In Long v. Quad Power Products, LLC, No. E2013-02708-COA-R3-CV (Tenn. Ct. App. March 20, 2015), plaintiff was injured while pressure testing a product at work. Plaintiff tried to turn a ball valve in the test, and when the valve would not turn he “used an extension or cheater bar to continue his attempt to relieve pressure.” A mechanism attached to the valve then broke, which caused extremely high-pressured water to hit plaintiff, injuring his left arm and shoulder. Plaintiff eventually had to have his left arm amputated. At the time of appeal, there was only one defendant remaining in the case: the distributor from whom plaintiff’s employer purchased the ball valve used in the testing system. According to this defendant, however, this ball valve would have only been in its possession for around 24 hours and was not “assembled, designed, manufactured, or altered” by defendant. After some procedural history, the case eventually boiled down to a strict liability failure to warn claim on which the trial court granted summary judgment to defendant, and the Court of Appeals affirmed.
When granting summary judgment for defendant, the trial court made certain relevant findings of fact: that the “failed component was not a part of the valve sold by defendant;” that the ball valve had actually been removed from service several days before the accident because it was difficult to use, but that in violation of the employer’s own safety rules it was later put into the test panel used by plaintiff; that a “simple inspection” by the employee who put the valve in the test panel would have showed that it was corroded; and that if the employer “had properly supported the valve in its test panel, the stress in the connected components would not have been sufficient to cause the connecting components to fracture.” In affirming summary judgment, the Court of Appeals relied on these facts and addressed four issues raised by plaintiff.
