LINCOLN -- When school starts next Tuesday (Aug. 12) in Lincoln's public schools, teachers, staff and students will be learning a new emergency response protocol. Instead of a generic CODE RED, the new protocol is a clearly defined and consistent response to various school incidents. The district will use four, consistent actions which can be performed during emergencies. They are LOCKOUT, LOCKDOWN, EVACUATE and SHELTER. LPS Security Director, Joe Wright, says plain language responses will allow people to be quicker and more efficient for emergencies.
