5.6 Integrating the Incident Command System (ICS)

Key Takeaways

  • Incident command coordinates roles and interfaces with the responding agencies.

  • Emergency warnings should not wait for a media holding-statement approval process.

  • A verified holding statement states known facts, safety actions and the next update route.

Integrating the Incident Command System (ICS)

During a major crisis, private event organizers must interface seamlessly with public safety agencies (police, fire, EMS, municipal emergency management). The Incident Command System (ICS) is the standardized, modular, all-hazard management framework utilized across public and private sectors under the National Incident Management System (NIMS).

The Event ICS Organizational Hierarchy

Under ICS principles, command is structured around a single Incident Commander supported by Command Staff and four operational General Staff sections:

ICS Leadership Roles and Authorities

  • Incident Commander (IC): The individual holding overall command authority and responsibility for managing the incident scene, establishing strategic objectives, approving resource allocation, and coordinating with the municipal public safety incident commander.
  • Safety Officer: A critical command staff role with the independent legal authority to immediately halt, modify, or terminate any operational activity that poses an imminent life safety danger. The Safety Officer monitors hazardous environments, ensures personal protective equipment (PPE) compliance, and reports directly to the Incident Commander.
  • Public Information Officer (PIO): The single designated individual authorized to gather, verify, coordinate, and release official information to the media, public, and attendees. No other staff member may speak publicly.
  • Liaison Officer: Serves as the primary operational point of contact for assisting and cooperating agencies, including municipal fire departments, police liaisons, hospital networks, and utility providers.
  • Operations Section Chief: Manages all tactical operations directly focused on executing life safety actions, including crowd evacuation, first-aid administration, search and rescue, and access control.
  • Planning Section Chief: Collects, evaluates, and disseminates incident intelligence; tracks resource status; maintains incident documentation; and develops the ongoing Incident Action Plan (IAP).
  • Logistics Section Chief: Secures all necessary physical facilities, transportation, medical supplies, fuel, telecommunications equipment, food, and water for emergency responders.
  • Finance / Administration Section Chief: Tracks all financial expenditures, contracts, worker time logs, vendor compensation claims, and legal documentation for post-incident insurance recovery.

The Crisis Communications Plan

In an era of ubiquitous smartphones and real-time social media streaming, information—and false rumors—spreads within seconds. A disciplined Crisis Communications Plan ensures accurate information dissemination, maintains life safety instructions, and mitigates long-term reputational damage.

The Three Phases of Crisis Communications

  1. Pre-Crisis: Establish the crisis communication team (CEO, Meeting Director, Legal Counsel, Head PR Director). Draft, review, and pre-approve standardized holding statements for the top 10 identified risks in the Risk Register. Configure mass notification technology.
  2. During Crisis: Activate notification systems, enforce the sole spokesperson rule, deploy holding statements within the initial 15-minute window, monitor social media channels for dangerous disinformation, and hold structured media briefings.
  3. Post-Crisis: Conduct comprehensive stakeholder debriefs, provide ongoing support updates to affected attendees and families, release after-action reports, and transition communication channels back to regular messaging.

Prompt, Verified Holding Statements

Core Elements of a Professional Holding Statement:

  1. Acknowledge the Situation: State the verified event that has occurred without speculating on cause or assigning blame.
  2. State Current Life Safety Actions: Describe the immediate actions being taken by organizers and emergency responders.
  3. Provide Clear Attendee Directives: Issue actionable instructions to attendees (e.g., stay indoors, proceed to Assembly Area B, avoid North Concourse).
  4. Commit to Next Update: Specify the exact time and official digital channel where the next verified update will be published.

Sample Holding Statement: "At 10:15 AM, an electrical transformer malfunction occurred in the South Exhibition Hall of the Convention Center, resulting in localized smoke and an automated alarm. Emergency responders from the City Fire Department are on scene. All attendees in the South Hall have been evacuated to outdoor Assembly Area B. Please remain clear of the South Concourse. Our next official update will be released via the event mobile app and website at 10:45 AM."

The Rule of the Sole Spokesperson

All public, media, and digital communications must flow exclusively through the designated Public Information Officer (PIO) or named corporate spokesperson. Mandate strict internal discipline:

  • All event staff, temporary crew, contractors, and volunteers must be trained to decline comment politely and immediately direct all media inquiries to the official Media Center.
  • Enforce a strict social media blackout policy prohibiting staff and crew from posting personal photographs, videos, or commentary regarding the crisis from personal accounts.
  • Uncoordinated or speculative statements by unauthorized personnel can be deemed binding admissions against the organization in subsequent tort litigation and can compromise commercial insurance coverage.

Mass Notification Infrastructure

Emergency messaging must be delivered across redundant, omnichannel communications pathways:

  • Push Notifications & In-App Alerts: Automated mobile event application broadcast alerts.
  • SMS Gateway: Priority text messaging deployed to all registered mobile numbers.
  • Digital Signage Override: Centralized override of all electronic lobby boards, meeting room display monitors, and LED video walls with prominent emergency instructions.
  • Public Address (PA) Audio Announcements: Standardized, clear vocal instructions repeated across facility-wide public address speakers.

The Media Holding Center

Designate a physical media room located away from the Incident Command Post, victim triage zones, and attendee assembly muster points. Isolating the media protects attendee privacy, prevents journalists from filming traumatized individuals or medical interventions, and ensures public safety officials can brief reporters in a controlled, professional environment.

Warning

Never say "No Comment" to journalists during an unfolding crisis. "No comment" projects guilt, indifference, and lack of operational control. Instead, state: "Our primary priority is the life safety of our attendees and staff. We are actively coordinating with emergency responders to secure the area, and we will provide our next verified operational briefing at [specific time] in the Media Briefing Center."
