Stop the Bleed Save a Life

Compressing the Zones of Care

The Hartford Consensus recommends that an integrated active shooter response should include the critical actions contained in the acronym THREAT:

  • Threat suppression
  • Hemorrhage control
  • Rapid Extrication to safety
  • Assessment by medical providers
  • Transport to definitive care

A key component of the Hartford Consensus is this:

In the immediate aftermath of a mass casualty event, some lives may be lost through caution. The standard approach has been to cordon off the zone of casualties, a wide “hot zone,” until it’s been ensured that all threats are  suppressed. The Hartford Consensus suggested that the plan be modified to allow earlier access to victims outside the real hot zone, the location of the active shooter, or a possible bomb. Thus, agreement on new systems of integration and coordination between law enforcement and other teams of responders is needed to ensure the mutual understanding and sequencing of roles.*

By compressing the “hot zone” with the two other zones of care, the “warm zone” and the “cold zone,” less time is lost and more time is made available to begin bleeding control techniques so that more lives are saved (see diagram below).
