Which of the following is NOT included in the important pre-incident information?

The correct response highlights that available staffing resources are not typically classified as important pre-incident information. Pre-incident information primarily focuses on aspects that are vital for immediate tactical decision-making in response scenarios.

Water supply details are crucial because they directly affect firefighting efforts, determining how much water is available for suppression and where to access it. Hazards to personnel are essential to identify in order to ensure the safety of responders and to plan appropriate safety measures. Similarly, knowledge about building construction is critical. It helps incident commanders understand how fire might behave within a structure and informs strategies for response.

Staffing resources, while important for operational planning, are generally more relevant to organizational capacity and logistics rather than immediate incident response procedures. Thus, they do not fall into the category of information that is typically gathered and evaluated before an incident occurs.
