What type of emergency situation is indicated by a "Full Emergency" alert in airport firefighting?

In airport firefighting, a "Full Emergency" alert signifies a Major Fire or Incident. This type of alert is issued when there is an imminent threat to life, safety, or property, typically involving significant danger from fire, hazardous materials, or critical situations that require an immediate and coordinated response from emergency services.

When such an alert is activated, it indicates that firefighters must be prepared to mobilize all available resources to handle a severe situation, potentially involving multiple casualties, aircraft accidents, or large-scale fires. This higher level of alert ensures that all necessary personnel and equipment are ready to respond effectively to contain the situation and protect lives and property.

Other scenarios, like a Minor Incident or an Aircraft Incident, do not trigger the same level of urgency or resource allocation as a Full Emergency does. Critical Aircraft Failure might be serious but may not necessarily involve a fire or immediate danger, which is why it does not equate to the level of a Major Fire or Incident recognized in a Full Emergency alert.
