A personal injury claim was filed concerning an accident at the San Francisco International Airport during final construction of a baggage handling conveyor belt system. Dr. Vardi was the court qualified expert witness called in to investigate and provide expert testimony regarding proper Lock-out, Tag-out safety procedures, OSHA requirements and construction industry standards. This multi discipline work site included a general contractor, electrical contractor and millwright installers. Each of them worked separately and together in the installation of this complex computer operated material handling system. Due to ongoing airport operation our investigation included early AM inspection and conclusion before the start of the new operating day. The jury trial took place at the San Francisco County Superior Court and the case is now pending in the California Court of Appeals. Dr. Vardi has provided trial testimony in Los Angeles County Superior Court, Ventura County Superior Court, Orange County Superior Court, San Diego County Superior Court, San Bernardino County Superior Court, San Luis Obispo County Superior Court, Riverside County Superior Court, Sacramento County Superior Court, U.S. Federal District Court – San Francisco, and U.S. Federal District Court – Los Angeles
