During some emergencies, it may become necessary to “Lockdown” a building or buildings on an installation to protect lives and minimize the overall exposure to danger.
A Lockdown, similar to Shelter in Place (SIP), is a temporary sheltering technique utilized to limit exposure to a threat, such as an Active Shooter incident. It is the immediate movement or removal of all personnel from the outside to inside structures. When alerted, occupants of any building within the subject area will lock all doors and windows, barring entry or exit to anyone until the “all clear” has been sounded. This procedure converts any building into a large “Safe Room.” A Lockdown can last from a few minutes to several hours, depending on the situation.
