If there’s a safety threat at Fort Lauderdale-Hollywood International Airport, there’s now multiple ways for officials to warn visitors of the danger and to tell them what to do. Passengers and other visitors will also be able to reach out quickly to airport managers if they find themselves in the middle of an emergency. The changes are meant to prevent the mass confusion and chaos that forced the airport to close after five people were killed in the baggage claim area in January 2017. The shooter was captured in minutes, but passengers were stranded on the tarmac for hours. “Now we have a way of notifying everybody with a smart phone if there’s an emergency,” Mayor Mark Bogen said. “Now they’ve put communication devices throughout the airport.”
