Critical Incident Stress Intervention and Support (CrISIS)


Critical Incident Stress Intervention and Support (CrISIS) - is a comprehensive, integrated, systemic and multi-component approach to addressing psychological trauma.

Consisting of seven protocols which are applied dependent on the context of the situation encountered, CrISIS provides a coherent and evidence-based system of assisting people and organisations through a crisis experience.

Applied and developed in the aftermath of the London terror attacks of  2017 and the Grenfell Tower disaster, CrISIS represents an evolutionary development in resolving trauma after a critical incident.

Unlike older trauma risk management models, CrISIS provides evidence-based and effective resolutions for those who have suffered a traumatic reaction, preventing the need for clinical referral.

What is a critical incident?

A critical incident is an incident with the potential to overwhelm an individual’s usual ability to cope.

From a person-centred point of view, it is the subjective reaction that determines the impact and not the event itself; how individuals label, assign meanings to, or are disrupted physically and psychologically by an event will contribute to whether it is experienced as a ‘critical’.

Examples of critical incidents that could be experienced in an operational environment include, but are not limited to:

  • Multiple/mass fatality
  • Death of a colleague
  • Death of a child
  • Failed rescue operation
  • Violent crime
  • Terror attack/PLATO responses
  • Involvement in a series of critical incidents over a short period of time
  • Incidents which have a personal connection (e.g. victim known)
  • A murder scene, suicide or witnessing of a violent crime
  • Incidents involving operational difficulties (e.g. flashover, near misses or contamination, handling a survival call)
  • Incidents which have heightened media attention or public response
  • Failed resuscitation/s
  • Incidents involving people suffering from abuse and/or neglect

Example of critical incidents that may be experienced in a non-operational environment include, but are not limited to:

  • Sudden bereavement
  • Divorce/relationship closure
  • Serious breach of trust
  • Bullying/harassment
  • Personal injury
  • Road traffic collision
  • Violence
  • Childhood sexual exploitation
  • Rape
  • Natural disaster
  • Hostage situations
  • Near miss/close calls
  • Domestic violence
  • Significant business failure/financial loss

CrISIS facilitates continued organisational performance throughout and beyond incidents that would otherwise threaten the mental health of your people and thus, business continuity. To date, we have provided key infrastructure organisations and businesses with effective support during and in the aftermath of the following major incidents:

CrISIS facilitates continued organisational performance throughout and beyond incidents that would otherwise threaten the mental health of your people and thus, business continuity. To date, we have provided key infrastructure organisations and businesses with effective support during and in the aftermath of the following major incidents:


  • All of our CrISIS facilitators have emergency service and military backgrounds, so understand better than most the difficulties your people and organisation can face during and following a critical Incident
  • Your people need to have confidence in those commissioned to help them - because we’ve ‘been there’, we tend to be more trusted than normative counsellors or psychiatrists.
  • CrISIS protocols are designed to interface with any command and control or business management systems.
  • CrISIS has been used to deal with arguably the highest profile critical incidents of the last decade.
  • The effectiveness of CrISIS has been proven in the field – real people, real trauma, real recovery.
  • Our CrISIS team is available to deploy at short notice to support your organisation during a critical Incident, and throughout recovery operations thereafter.
  • Our CrISIS team have received commendations for their effectiveness, and their experience is second to none.
  • CrISIS provides a unique assurance during periods of intense stress and organisational strain.
  • CrISIS facilitates effective recovery from trauma, not clinical referral, like older trauma risk management systems

Westminster Houses of Parliament

The tragic killing of PC Keith Palmer and a number of innocent civilians at the hand of Khalid Masood at Westminster Palace resulted in a great deal of distress for officers involved in the incident.

Mobilised quickly after the attack, we were able to provide effective trauma support in a situation which had the added and awful caveat of the loss of a colleague in highly public circumstances.

Key officers involved in the attack and its aftermath were provided with 1-1 CrISIS interventions in order to resolve their traumatic reactions prior to the need for clinical referral.

All officers receiving CrISIS interventions returned to work their very next duty shift save one, whose physical injuries prevented it.

CrISIS Case Study - The London Bridge/Borough Market Terror Attack
Borough Market

Mobilised to support responders involved in the second major terror attack of 2017 in London, our CrISIS team responded quickly following the multi-zoned, multi-agency, and multiple-fatality incident.

Our experts advised senior commanders regarding a progressive and highly co-ordinated CrISIS recovery operation, utilising our Multi-Agency Strategic Support (MASS) protocol.

Following the initial MASS operation, Our CrISIS facilitators provided 1-1 support for those who were assessed to be enduring trauma as a result of their involvement in the attack, including 999 Call Handlers who had received survival calls from members of the public who were at the time being attacked themselves.


Grenfell Tower - London

Our CrISIS team was mobilised to provide support for responders immediately following the emergency phase of what was arguably London’s greatest disaster for many years.

After strategic consultation, we carried out psychological assessments of officers involved, followed by a highly-structured process of multiple and concurrent group crisis interventions.

Individuals identified through full psychological assessment and CrISIS protocols found to have suffered a traumatic reaction were then provided with further 1-1 support, and returned to active duty within 28 days of the incident taking place.

1-1 Support was also provided for senior Incident commanders, in order to ensure that they could continue to function optimally, thus assuring business continuity at a crucial time of organisational strain.

Grenfell was itself a challenge due to its ongoing nature throughout the victim recovery phase, and we were able to provide support to professionals from the Disaster Victim Identification (DVI) teams and forensic anthropologists involved in the recovery phase of the operation. Advice and guidance was provided to maximise psychological well-being within the inner cordon of Grenfell Tower, which ranged from guidance on working conditions and welfare provision during very challenging operations.

Levels of sickness due to mental health issues fell in the aftermath of the incident, and our CrISIS team members were awarded commendations for their effectiveness.
