Along with access security utilities and exposures, what other site consideration comes into play when developing a pre-incident plan?

A pre-incident plan is a comprehensive document used by emergency responders to manage an incident effectively. The plan gathers critical data about a site before an emergency occurs. Along with site access, security features, utility shutoffs, and surrounding exposures, the water supply is a fundamental consideration. Information regarding the location of hydrants, fire department connections (FDCs), static water sources (e.g., ponds, tanks), available flow rates, and system pressures is essential for developing a viable fire attack strategy. This data directly influences apparatus placement, hose lays, and the overall tactical approach, making it a primary component of the site assessment.

B. Parked vehicles: This is a transient condition that affects site access, which is already a listed consideration, rather than being a distinct primary category.

C. Vegetation: This is typically evaluated as a type of fuel load or an exposure hazard, a category already included in the question's premise.

D. Environment: This term is overly broad. While specific environmental factors like topography are part of a plan, "water supply" is a more distinct and critical resource category.

1. NFPA 1620, Standard for Pre-Incident Planning, 2020 Edition.

Section 4.4.2.2, Site Considerations. This section lists the key data points to be collected regarding a site. The list explicitly includes: "(1) Access, (2) Security... (4) Water supply, (5) Utilities, (6) Exposures..." This directly supports that water supply is a primary site consideration alongside the others mentioned in the question.

2. International Fire Service Training Association (IFSTA), Oklahoma State University. Fire and Emergency Services Company Officer, 6th Edition.

Chapter 6, "Company-Level Preincident Planning," Page 201. The text outlines the process of conducting pre-incident surveys. Under the section "Gathering Information," it details the essential elements to document, stating, "The survey should begin on the outside of the building... Note the locations of fire hydrants and other potential water sources." This reinforces the water supply assessment as a foundational step in pre-incident planning.

3. University of Cincinnati, Fire Science & Emergency Management Program Courseware (FST 3033 - Fire Protection Systems).

Module on "Water Supply for Fire Protection." Course materials emphasize that a critical component of pre-incident planning and building assessment is the evaluation of the available water supply. The curriculum details the need to identify public and private water sources, test hydrant flow, and verify the operational status of all water-based fire protection systems, confirming its status as a key planning element.
