What is the first step to ensure before entering a scene?

Determining scene safety is the first step before entering any situation, particularly in a law enforcement or criminal justice context. Before assisting anyone or taking further action, an officer must ensure that the environment is safe for themselves and others involved. This involves observing the surroundings for potential hazards, such as weapons, aggressive individuals, or environmental dangers (like fire or unstable structures).

By prioritizing scene safety, the officer can avoid becoming another victim or increasing the chaos, which allows for a more organized and effective response. Once safety is established, the officer can then focus on assessing victims, calling for backup, or providing assistance as needed. In emergency situations, acting without assessing safety can lead to additional danger, making this step essential for effective first response.
