Mass fatality incident

Mass Fatality Incident (abbreviated MFI) is an emergency management term used to identify an incident involving more dead bodies and/or body parts than can be located, identified, and processed for final disposition by available response resources.

Although it is a somewhat relative term in that there is no widely accepted number of fatalities that define an MFI, it is generally recognized that if the number of fatalities exceeds the local city or county's resource capabilities causing them to request assistance, or mutual aid, from neighboring jurisdictions, the term applies.

Mass fatality incidents may or may not be a result of a mass casualty incident (MCI), which is considered a different type of incident and usually focuses more on managing the surviving victims of an incident. MFI and MCI may, and often do, occur simultaneously. MFI differ from MCI in that most, if not all, of the victims of the incident are deceased. A catastrophic plane crash with no survivors is one example of an MFI. Part of the distinction between MFI and MCI is because different kinds of resources are needed to manage each. Living victims are attended to by medical personnel such as EMS, deceased victims are attended to by medical examiners or coroners.

Mass fatality incidents may be either human-caused, such as hazardous materials releases, transportation accidents, or terrorist attacks, or they may be the result of natural disasters such as earthquakes, floods, or severe weather.

Some significant mass fatality incidents are:

One of the naturally occurring incidents with great potential to cause a MFI is pandemic influenza (flu). The Spanish Flu pandemic of 1918 killed millions and overwhelmed response resources on a global level. A modern pandemic could have similarly overwhelming impacts. Catastrophic incidents that result in mass fatalities usually also result in mass injuries and/or illnesses. While it is more important to dedicate resources to care for the living, many people have public health concerns about the dead. This is one important reason why jurisdictions usually include mass fatality planning as part of their overall emergency preparedness efforts.

After some MFIs authorities have conducted hasty mass burials, and research has shown this is a generally unsatisfactory response. Mass burials are usually not required for public health reasons, they increase distress among survivors and interfere with long-term community recovery. In all cultures there are customs and rituals for dealing with the dead. Universally survivors want to know what happened to their loved ones, and that their loved ones' remains were treated with respect. These are important reasons to plan for mass fatality management.
