Police explain meaning of ‘Major Incident’ after Saturday’s serious collision on A55 at Holywell

Police in North Flintshire responded to 72 calls for service in the past 24 hours, including 10 urgent incidents requiring blue-light attendance.
Officers dealt with eight domestic incidents, four concerns for safety, and four reports of anti-social behaviour.
Two arrests were made, one for a warrant relating to a breached order and one for drug driving.
Twenty-four incidents required reports to be written, with six recorded as crimes so far.
Police also addressed public queries about the term ‘Major Incident’ following Saturday’s serious collision on the A55, which has continued to cause disruption while emergency barrier repairs are carried out.
A spokesperson said that a ‘Major Incident’ can be declared by any emergency service when significant resources are needed to manage an incident.
It triggers protocols and procedures, ensuring all relevant agencies, such as ambulance, fire, highways and Traffic Wales, are involved.
As part of the process, a M/ETHANE message is sent, containing:
- Major Incident – is it one?
- Exact location
- Type of incident
- Hazards present
- Access and egress routes
- Number of casualties and severity of injuries
- Emergency services present or required
Police stressed that a Major Incident does not always mean there are multiple casualties or a serious crime, but rather that the situation requires substantial coordination between agencies.
