Which order is recommended when performing searches away from the fire in a multi-story building?

• A. Vertical Plane First, Then Horizontal Plane
• B. Horizontal Plane First, Then Vertical Plane
• C. Diagonal Plane First, Then Vertical
• D. Vertical Plane First, Then Diagonal

Answer: (A)

The method being tested is to move through the building using the vertical plane first, typically by using the stairs, and only after establishing access to a floor to then sweep that floor horizontally. This vertical-first approach ensures you reach every level and establish a safe, repeatable path of egress before you begin room-by-room clearance. Stairwells usually offer a more controlled, tenable route than smoke-filled corridors, so prioritizing vertical progression reduces the risk of missing occupants on upper floors and keeps teams together as conditions change. Once you’ve reached a floor, you then perform a thorough horizontal search to clear rooms and corridors on that level, ensuring no space is left unchecked on that floor before moving to the next. Starting with horizontal search or attempting a diagonal pattern does not guarantee complete floor or building-wide clearance and can leave upper levels unchecked or complicate retreat paths.
