Explanation:

When it comes to incident management, we can define situational awareness as the ability of taking in as much information as possible upon arriving at the scene. That will include understanding objects, environmental conditions, people, interactions, etc. so as to act in a proactive (as opposed to reactive) manner. This ability is crucial to avoid negative impact and prevent aggravating the situation.
