Nothing in Sections 34-200 through 34-235 of this Code prevents the district from taking emergency action to protect the health and safety of students and staff in an attendance center. In the event of an emergency that requires the district to close all or part of a school facility, including compliance with a directive of a duly authorized public safety agency, the chief executive officer or his or her designees are authorized to take all steps necessary to protect the safety of students and staff, including relocation of the attendance center to another location or closing the attendance center. In such cases, the chief executive officer shall provide written notice of the basis for the emergency action within 3 days after declaring the emergency and shall publish the steps that have been taken or will be taken to address the emergency within 10 days after declaring the emergency.
