When completing a diagram of the preincident survey, you should include specific features such as which statement to reflect accessibility limitations due to terrain?

• A. If topography makes one or more sides inaccessible to fire apparatus
• B. The operation at fire pump
• C. Names and location of key security personnel
• D. Type of elevator and service contractor used

Answer: (A)

Accessibility and terrain limitations are what this item highlights. When you map the preincident survey, noting which sides of the building are inaccessible to fire apparatus because of the terrain helps responders plan where engines and ladders can actually reach, where hose lays must be routed, and where rescue or entry will have to occur from accessible angles. This information directly influences apparatus placement, water supply strategy, and overall firefighter safety, since it shows early on which approaches are viable and which are not. Other details like pump operation, security personnel, or elevator information are important for other aspects of incident management, but they don’t convey how terrain affects access and approach on the diagram.
