Sometimes there are warning signs of an active threat event before an attacker enters the building. These warnings could be:

• A warning call from the BOEC (911 dispatch), or from the Security Operations Center.
• Staff observing a gun being loaded or prepared outside the building.
• Staff hearing someone outside make explicit threats to engage in killing.

In these or similar scenarios staff may perform a "lockout," closing and locking the exterior doors to slow down or prevent an attacker from entering. If it is safe to do so, staff would perform a lock out by:

• Getting door key(s) and securing the door(s) quickly as possible before moving away from doors or windows.
• While moving to the safest position possible, making best attempts to alert others to the danger and to warn them away from vulnerable doors and windows, as well.
• The PIC should be notified as soon as possible if a lockout will occur. And the longer a lockout is in effect the more people in an employee's chain of command should be notified (as soon as practical) from the Person In Charge (PIC), to location leaders, up to the Executive Management Team Person In Charge (EMT PIC).
• Patrons who wish to leave during a lockout cannot be detained and must be allowed to exit the building. If it is safe to do so these patrons should be warned of the risks of opening doors. Staff may direct patrons who wish to leave to an alternate exit that poses less of a risk.
• An incident report will always be written for a lockout.
• If the original warning of danger did not come from 911 dispatch or the Security Operations Center, staff should report the imminent danger as soon as possible by calling 911.
