Multiple Casualty Incident
Mass Casualty Incident (Significant Incidents)
Major Incident
Where the number of casualties (temporary) exceeeds the capacity available of the healthcare resources (at the incident)
For example: you could be covering a running event, at the finish line medical post you may have 10 patients in quick succession who collapse, and there is only 4 responders covering the area. At this point you could argue you have a multiple casualty incident, as you have 10 collapsed patients and only 4 people to treat them.
However, this a temporary issue - you can call in additional support from surrounding medical teams, such as cycle responders, other medical posts and ambulances.
So you have a temporary incident but can cope with the resources available
Multiple casualty incidents often:
need more resources deployed to the scene to help out
containable in a short time
Where three or more casualties in close proximity are incapacitated with no obvious reason.
A first responder includes any member of the emergency services who is likely to be the first operational resource to be deployed to a CBRN incident.
The person is unlikely to be trained in specialist CBRN response or have specific CBRN Personal Protective Equipment (PPE). This also includes staff at Health Care premises who may be required to carry out the role of a first responder. It focuses on the multi-agency first response and the initial life-saving phase of a CBRN incident, and is intended to enable control room personnel and first responders to facilitate or undertake life-saving actions as soon as possible.
This approach also promotes close inter-agency working, which is vital in responding effectively to a CBRN incident.
Previous protocols for the response to a CBRN incident, dictated that unprotected emergency responders should withdraw from the scene and await the arrival of specialist trained and equipped assets (STEP 1,2,3). However, recent evidence has pointed to a need for a more rapid and flexible approach to a CBRN incident.
Visual Indicators
Visual Indicators Visual indicators of a CBRN event may include all or some of the following:
Dead or distressed people, birds and animals
Multiple individuals showing unexplained signs of skin, eye or airway irritation; nausea; vomiting; twitching; sweating; pin-point pupils; runny nose; disorientation; breathing difficulties; and convulsions
The presence of hazardous materials or unusual materials/equipment
Unexplained vapour or mist clouds
Unexplained oily droplets or films on surfaces or water
Withered plant life and vegetation
Note: Symptoms of exposure to a biological or radiological attack may not be present within the first minutes and hours of an attack occurring. Chemical releases are often, but not always accompanied by a more rapid onset of symptoms.
In the early stages of an incident, it may be difficult to establish whether a CBRN event has occurred
STEP 1-2-3 Plus - Safety Triggers for Emergency Personnel
STEP 1-2-3 is a familiar and well-established protocol for assessing the likelihood of hazardous materials being present at an incident scene, and determining subsequent actions. In this guidance, first responders are directed to consider a range of life saving actions once they have established that the situation requires a STEP 3 response.
This is known as STEP 1-2-3 Plus:
Step 1: One person incapacitated with no obvious reason
Approach using standard protocols
Step 2: Two people incapacitated with no obvious reason
Approach with caution using standard protocols
Step 3: Three or more people in close proximity, incapacitated with no obvious reason
Use caution and follow plus Plus:
Follow the CBRN First Responder Flow Chart to consider what actions can be undertaken to save life, using the following principles:
Evacuate – get people away from the scene of contamination
Communicate and advise – immediate medical advice and reassurance that help is on its way
Disrobe – remove clothing
Decontamination – dry decontamination should be the default process
Incidents that require significant medical resources to be deployed to the scene
Examples include:
Significant transport incident
Terrorist attack
Definitions
"Emergency means an event or situation which threatens serious damage to a place in the UK" [Civil Contingenceis Act]
"An event or situation requiring a response under one or more of the emergency services major incident plans" [Cabinet Office]
"An event or situation with a range of serious consequences which requires special arrangements to be implemented by one or more emergency responder organisation" [JESIP Definition]
In health service terms, a major incident is: "an incident where the number, severity and type of live casualties requires extra ordinary resources"
The word 'live' makes a big difference -multiple dead patients would not trigger a major incident response from health (ambulance, medical and hospitals), however would from Fire or Police
Major incidents can be natural or man-made
Natural: Floods, fires, earthquakes (can be long lasting events)
Man-made: Terrorism, transport, mass gatherings or industrial (usually self contained incidents)
Major incidents can be simple or compound in their nature
Simple: hospitals, communications, infrastructure remain intact
Compound: damage to transport, communications or ineffective health services
Major incidents can be compensated or uncompensated
Compensated: where the load is less than the extra ordinary capacity (most UK incidents)
Uncompensated: load of live casualties exceeds surge capacity (rare in the UK)
For each of the incidents below, can you categorise them as:
Natural or Man-Made
Simple or Compound
Compensated or uncompensated
You can reveal the answers using the downward arrow
Man-made- Terrorist act
Simple - hospitals, roads, communications needed remained intact
Compensated - very quickly they had more than sufficient resources to deal with immediate casualties
Natural: Fire is categorised as a natural incident
Compound - communications on site (due to metal sheeting and thick concrete) adversely effected, the video link from the helicopter deployed for SILVER commanders to view the incident also went down on the day
Compensated - very quickly they had more than sufficient resources to deal with immediate casualties
