What techniques can be used to locate hazards?

• A. Circle, lane, cloverleaf, grid
• B. Zig-zag, lane, circle, grid
• C. Zig-zag, lane, cloverleaf, grid
• D. Zig-zag, line, cloverleaf, grid

Answer: (C)

Locating hazards effectively comes down to using systematic search patterns that ensure you cover the area without leaving gaps. Each pattern serves a purpose, and combining them gives you flexibility to detect hazards in different layouts and under various conditions.

The zig-zag pattern snakes through the space, providing thorough coverage and catching hazards that might be missed if you move in a straight line. The lane pattern moves along parallel strips, which is efficient for long, narrow areas where you can sweep one pass after another with minimal backtracking. The cloverleaf pattern loops around a central point and out into four lobes, good for ensuring you survey around obstacles or a central feature without neglecting the surrounding zones. The grid pattern lays out a uniform, square or rectangular network, guaranteeing consistent spacing and comprehensive coverage across the entire area.

Using these four techniques together lets you adapt to terrain, size, and obstacle layout while maintaining a high likelihood of detecting hazards. Other patterns like circular sweeps or simple straight lines can miss edges or blind spots, making them less reliable on their own.
