Proven Success

The Numbers Don’t Lie

No interior locked classroom door has ever been kicked in or breached by an active shooter.  Beware of salesmen selling cave-man technology school door barricades that break the law and violate NFPA 80 fire codes and Life Safety 101, along with ADA non compliance.  These school door barricades are a liability problem for schools and could cause unintended and very dangerous consequences if a predator used them. Staff and first responders may not be able to get into a classroom.

Old School door removal and replacement. Retrofit your school entrance and add a vestibule for an added layer of door security to your school entrance.

The main entrance of a school should be clearly marked and direct traffic through a secured vestibule that is visible from the main office where visitors are directed to walk through in order to gain entrance into the school.  Perimeter doors should be limited, and locked at all times.  Vestibules should  be transparent  for natural surveillance, and hollow metal window walls provide that surveillance and bolistic film can be added to the windows.  Bullet proof glass can be added at a reception window for optimum protection.

School main entrance doors should have vestibule doors

Good school entrance vestibule design


This is an example of a good design I found, published by the Texas Association for School Administrators.
