Secure the Perimeter
All students and staff should be brought into the main building. ALL exterior doors to the building should be locked and verified to the extent that it can be done safely. Class changes, if applicable, should be allowed only within the main building. No one should be permitted to go outside to portables or engage in any outside activity. An announcement will be made “All personnel, we are under a Lock Out.” Arrangements must be made to bring in all students from the outside and or temporary classrooms. The announcement should be repeated at least once.
