Which sequence best describes an effective lockdown procedure?

• A. Announce lockdown, secure all access points, account for personnel, and communicate status to emergency responders.
• B. Close the building and ignore access points.
• C. Only lock doors without communication.
• D. Lockdown only after arrival of police.

Answer: (A)

In an active-threat situation, the priority is to protect people quickly through a coordinated, all-hazard response. The best sequence focuses on four critical actions in rapid order: announce the lockdown so occupants shelter in place and minimize movement, secure all access points to prevent intruders from entering or exploiting openings, account for everyone to know who is safe, missing, or in danger, and communicate the current status to emergency responders so they have real-time information to plan a precise, safe intervention. These elements work together to limit exposure, reduce risk, and enable responders to act effectively. Alternatives that skip communication, leave access points unsecured, or wait for police before locking introduce gaps and delays that can put people at greater risk.
