How do we sound?

Explanation:
A systematic left-to-right sounding is used to evaluate an opening for ventilation in a way that covers all areas and gives you a clear read on heat, smoke, and potential fire progression. Start at the left edge of the opening, then move to the center to assess the main area, and finish at the right edge. This sequence helps you catch any clues—like hollow sounds, heat pockets, or smoke patterns—that might be closer to one side, and it keeps your assessment organized so your team can coordinate door and window operations smoothly. Starting at the left edge and sweeping across ensures the boundary is checked first, then the core area, then the opposite edge, reducing the chance of missing a critical detail. Other sequences can be less reliable for quick, comprehensive evaluation and may disrupt the team’s mental mapping of the opening. In short, Left-Center-Right provides a consistent, thorough approach that aligns with how we systematically assess openings during vertical ventilation.
