Robinson v. APV Crepaco. Plaintiff was seriously burned when a diverter valve for a plate heat exchanger failed. Pig skin was grafted to the plaintiff to help heal the burns. His medical bills were over $1,000,000. After deposing plaintiff’s employer about the operation of the plate heat exchanger and the location and installation of the diverter valve, both plaintiff and his workers’ compensation carrier (which had voluntarily asserted a lien against any settlement proceeds or judgment) dismissed APV Crepaco from the lawsuit.
