Michael B. Thomas/Getty Images(EDWARDSVILLE, Ill.) The Occupational Health and Safety Administration has launched an investigation into the collapse of an Amazon delivery station in Edwardsville, Illinois, that left six people dead after a tornado pummeled the facility during the height of the busy holiday shopping season. OSHA spokesman Scott Allen told ABC News that compliance officers from the agency have been at the complex since Saturday to provide assistance. "OSHA has six months to complete its investigation, issue citations and propose monetary penalties if violations of workplace safety and or health regulations are found," Allen told ABC News in a statement. "No further information will be available until OSHA has completed their investigation." The Edwardsville Fire Department is still working to clear debris from the Amazon site and transition the property back to the company's control as of Monday, city officials said in a statement on Facebook,
Construction trucks and cranes returned to the Edwardsville Amazon Delivery Warehouse to continue searching through what remains of the building in Illinois.
