Which technique is recommended to map rooms during a search in smoke-filled conditions?

• A. Visual mapping from the doorway only
• B. Rely on memory of room layouts
• C. Use touch and tools to map rooms
• D. Shout directions to others to guide the search

Answer: (C)

When visibility is lost to smoke, you can’t rely on sight to understand the interior. The best way to map rooms is by using touch and appropriate tools. By keeping a hand on walls, doors, and other features as you move, you physically trace the layout, noting how spaces connect and where obstacles lie. This tactile sense builds an on-the-spot map of the building even when you can’t see clearly. Using tools to probe openings or measure spaces reinforces what you feel and helps confirm the layout, preventing misinterpretation. Relying on memory or trying to map from a doorway with limited visibility can lead you astray, and shouting directions doesn’t substitute for a usable interior map.
