To maintain a safe and secure environment for district students and staff, the Superintendent or designee shall ensure that the district's emergency and disaster preparedness plan and/or each school's comprehensive safety plan includes procedures for dealing with bomb threats. He/she also shall provide training regarding the procedures to site administrators, safety personnel, and staff members who customarily handle mail, telephone calls, or email.

The District has provided each school site with Emergency Procedures and Information Packets that contain specific procedures related to bomb threats and other emergencies. Online training is also available regarding bomb threats and emergencies.

Receiving Threats

Any staff member receiving a telephone bomb threat shall try to keep the caller on the line so as to gather information about the location and timing of the bomb and the person(s) responsible.

If the bomb threat is received through the mail system or in writing, the staff member who receives it should handle the letter, note, or package as minimally as possible. If the threat is received through electronic means, such as email or text messaging, the staff member should not delete the message.

Staff members who customarily receive telephone calls or handle packages shall receive training related to bomb threats.

2. Any student or employee seeing a suspicious package shall promptly notify the principal or designee.

3. The principal or designee shall immediately use fire drill signals and institute standard evacuation procedures as specified in the emergency plan.
