Robins prepping for exercises Published May 29, 2015 By Robins Public Affairs 78th ROBINS AIR FORCE BASE, Ga. -- The base will conduct a number of readiness exercises June 8 through 12. The exercises will evaluate, among other things, how the workforce and first responders react to active-shooter and hazardous-material scenarios. The active-shooter scenario will include the use of a new active-shooter alarm broadcast on the base's Giant Voice message system. The active-shooter alarm is a 15-second attack warning signal followed by the words "Lockdown, lockdown, lockdown." Both will be repeated every five minutes until the all clear is issued. The attack warning signal is a continuous wavering tone and should not be confused with the disaster warning signal - for things such as a tornado - which is a three- to five-minute steady tone. The hazard-material scenario will impact a limited number of personnel. However, all base organizations should review their shelter-in-place locations and procedures in preparation for the event, as well as for situational awareness should the need to shelter-in-place ever occur for real. As with all installation exercises, drivers may experience a temporary delay entering and exiting the base on at least one occasion during the week. Additionally, personnel may encounter restricted access and reduced services at some on-base facilities. WHAT TO KNOW: The installation command post will test its active-shooter alarm in advance of the actual exercise. It will test the alarm Wednesday at noon, as part of its weekly test of the base's giant voice message system. The active-shooter alarm is a 15-second attack warning signal followed by the words "Lockdown, lockdown, lockdown."
