What is the purpose of a wall-following technique in zero-visibility conditions?

• A. To locate an exit or safe path by keeping one hand on a wall and moving toward known exterior openings.
• B. To locate water leaks in walls.
• C. To maintain maximum distance from walls for safety.
• D. To determine room scale by measuring wall lengths.

Answer: (A)

In zero-visibility conditions, wall-following is used to maintain orientation and guide you toward a safe exit by keeping a hand on a wall. This creates a consistent boundary you can trace as you move, helping you stay oriented relative to the building and move toward exterior openings or known safe paths. The wall acts as a navigational cue, so you’re more likely to reach an exit rather than wander into unfamiliar or hazardous areas. Locating water leaks isn’t the aim of this technique, and staying as far from walls as possible would defeat the purpose of using a boundary to navigate. Trying to determine room size by measuring wall lengths isn’t practical when fast, safe egress is the priority.
