Which of the following should be included in initial response objectives?

In the context of initial response objectives, conducting a scene size-up is crucial for assessing the situation upon arrival. This objective involves quickly evaluating the scene for safety hazards, identifying victims, determining the nature of the incident, and taking note of any witnesses or evidence. A thorough scene size-up allows officers to formulate an appropriate response strategy, prioritize actions, and ensure the safety of all involved, including first responders. This foundational step equips officers with the necessary information to make informed decisions as the situation unfolds.

While other options may also play a role in an effective response, they are not primary objectives during the initial phase. For instance, contacting local businesses may take place later, charging individuals typically occurs after investigation and evidence collection, and arranging for road closures is a logistical detail that can be managed once a clearer assessment of the scene is established. Thus, the emphasis on conducting a scene size-up highlights its critical importance in ensuring a safe and effective response in the initial stages of any incident.
