What definition fits the term 'incident' in emergency management?

In the context of emergency management, the term 'incident' is defined as an occurrence that requires a response. This definition is crucial because it underscores the role of emergency management in addressing and mitigating situations that arise and could impact safety, health, or the environment. By focusing on the need for a response, it emphasizes that an incident is more than just an event; it is a situation that necessitates action to prevent harm or to manage the consequences.

Other options present distinctions that do not align with the established definition of 'incident.' For instance, a planned event does not inherently imply urgency or the need for a response, making it more of a scheduled occurrence rather than an incident. Similarly, labeling something as a minor issue suggests that it does not require significant attention or action, which contradicts the essence of an incident. Finally, a situation without a response needed cannot meet the definition of an incident, as the core concept revolves around the necessity for some form of action or intervention. Therefore, recognizing an 'incident' as an occurrence that requires a response accurately encapsulates its relevance in emergency management practices.
