Practicing for an emergency. Hundreds of first responders in Lynchburg spent the day learning what to do in the event of a worst case scenario. WDBJ7's Tim Saunders was at today's drill and joins us live in our Lynchburg Bedford Newsroom. Tim, who organized this event? It's put on by the Virginia Department of Emergency Management. They run through scenarios like this in different parts of the state every year. Today, they're putting Central Virginia to the test. Swat teams surround Sandusky Middle School. Armed with heavy weapons, they carefully survey the campus before making their way in through a back door. This is only a drill, but it's giving police a chance to put their emergency plans into action. Lieutenant Dave Gearhart/Lynchburg Police Department: "Drills such as thi always reveal flaws in your system, because no system is perfect." Wednesday is the first day of a regional emergency drill. Police and rescue workers from Lynchburg and surrounding counties are testing their ability to handle a major crisis. The scenario involves a mass shooting and hostage situation at a public school. Organizers used details from incidents that have happened around the country to give participants a realistic experience. Steve Smallshaw/ Broadcast Services Coordinator: "Thi has been good practice. It has almost been too real." Actors played the part of shooting victims, who were taken to Lynchburg General Hospital. Doctors, nurses, and EMT's learned how to treat a large number of injured people at one time. The drill also tested the city's communication skills. Public relations workers from local governments and private agencies practiced methods of sharing information. Smallshaw: "a lot o these folks have done this for many years, but even still this practice can be very invaluable." Computer simulations gave city workers a taste of what they might see on social media. a mock Twitter post shows a victim pleading for help inside the school, while a fake YouTube video shows a person being held at gunpoint. Smallshaw: "Thes are the kinds of situations that we're going to face, if this kind of incident does come up." While they hope this kind of situation never happens, organizers of the drill say Lynchburg would be well prepared. Gene Stewart/Virginia Department of Emergency Management: "Lynchburg reall has a great group of people here working together." The drill wraps up tomorrow with meetings to discuss lessons learned today and ways to improve for the future. Live in the Lynchburg Bedford Newsroom, Tim Saunders, wdbj7.
