What to Do in a Telephone Bomb Threat

Receiving a telephone bomb threat can be a high-stress situation requiring calm, precision, and prompt action. This article provides practical, evidence-based steps for individuals and organizations across the United States to handle a bomb threat over the phone. It emphasizes preserving life, protecting property, and ensuring proper reporting and follow-up while complying with official guidelines. The guidance is designed to be actionable for staff, administrators, and security teams who may face such threats in schools, offices, hospitals, or public venues.

Immediate Actions Upon Receiving A Threat

When a bomb threat is received by phone, the priority is safety and information gathering. Do not hang up or confront the caller; instead, try to elicit useful details while remaining calm. Use the following steps:

• Keep the caller on the line as long as safely possible and do not reveal sensitive information about security measures.
• Note the exact time of the call and the caller’s voice characteristics (gender, age, accent, speech patterns).
• Avoid promising or denying anything during the call; collect facts instead.
• Ask targeted questions such as:
  • Where is the bomb right now?
  • What does it look like?
  • What is the size and made of the device?
  • When will it explode?
  • Why was it placed here?
  • What is your name and your phone number?
• Record the caller’s language, background noises, and any suspicious details without interrupting the flow of conversation.
• Notify a supervisor or security immediately after the call ends, following the organization’s protocol.

Evacuation Procedures And Assembly Points

Evacuation decisions depend on the assessment of risk and official guidance. In many cases, evacuation is recommended if a credible threat is detected or if a device is found. Follow these best practices:

• Adhere to the organization’s emergency plan and local fire or police advisories.
• Evacuate calmly using the designated routes; avoid using elevators during a threat.
• Assist individuals with disabilities and communicate clearly about safe assembly areas outside the building.
• Take only essential personal items; keep hands visible and move away from the building in a predictable, orderly manner.
• Account for all personnel at the assembly point and report any missing persons to responders.
• Do not re-enter the building until authorities declare it safe.

Communication And Reporting

Effective communication with emergency responders and within the organization is critical after a bomb threat. Use these guidelines to ensure accurate and timely reporting:

• Call 911 or the local emergency number and provide the caller information you collected, the building layout, and the threat details.
• Share the time of the threat, the suspected location, and any observed suspicious items, if applicable.
• Inform on-site security leadership and facility management about the status of evacuation and assembly.
• Separate sensitive communications from the public area to prevent panic. Use a pre-approved incident number or code word to indicate ongoing threats.
• Coordinate with local authorities to determine when to resume normal operations.

Evidence And Documentation

Thorough documentation supports investigations and helps improve future responses. Capture and preserve relevant information:

• Record the exact wording of the caller’s statements when possible, without editing for tone or content.
• Document environmental clues such as the location of the call, the phone used, and any alarms triggered.
• Secure CCTV footage, entry logs, and access records that may be related to the threat.
• Maintain a log of all actions taken, including times of evacuation, shelter-in-place orders, and communications with authorities.
• Hold a post-incident debrief to review what worked well and what needs improvement, updating the emergency plan accordingly.

Post-Threat Coordination And Recovery

Once authorities have assessed the risk, the focus shifts to recovery, communication, and resilience. Key steps include:

• Receive and implement official clearance before resuming operations.
• Provide ongoing support to staff and students, including counseling resources if needed.
• Review the incident in a formal after-action report, noting response times, decision-making, and safety outcomes.
• Update security measures and evacuation routes based on lessons learned, including training for new staff and regular drills.
• Educate all stakeholders on recognizing suspicious behavior, reporting channels, and the importance of staying composed under pressure.

Preventive Measures And Preparedness

Proactive planning reduces risk and improves response quality. Consider these preventive strategies:

• Develop a comprehensive bomb threat response plan aligned with local laws and federal guidelines.
• Train staff and students with regular drills, focusing on calm communication, situational awareness, and orderly evacuation.
• Install and maintain security systems, such as access control, surveillance, and alarm systems, while ensuring they do not impede safe evacuations.
• Designate a crisis communications team to manage internal and external messages during an incident.
• Coordinate with local police, fire departments, and emergency management agencies to synchronize procedures and share best practices.
