Lockdown is used when there is an immediate threat to the school (i.e. school intruders).  Lockdown minimizes the intruders’ access to the school and secures staff and students in rooms.  As part of this procedure, everyone must remain silent in rooms until the situation has been declared safe by an authorized person (i.e. principal or police personnel). Please note that during a lockdown it is important for students to not use cell phones – this is to ensure the safety of our students.
