Which technique is used to locate hazards?

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

Answer: (A)

Systematic search patterns are used to locate hazards so you cover the area thoroughly and don’t miss hidden dangers. Zig-zag scanning sweeps across a space with back-and-forth motions, giving broad coverage quickly and helping catch hazards around corners or in clutter. The lane pattern follows defined paths or aisles, which is especially efficient in spaces with obstructing shelves or equipment, ensuring you don’t overlook hazards between sections. The cloverleaf pattern rotates around a central point, allowing a multi-directional sweep to reveal hazards that radiate from a center or are blocked from straight lines of sight. The grid pattern divides the area into small, manageable cells and guides you through a two-dimensional thorough check, ideal for open rooms or areas with defined boundaries.

Using these patterns together provides comprehensive coverage for locating hazards in varied layouts, which is why this set is the best choice. Other patterns, like relying on a single circle or a single straight line, don’t guarantee that all edges, corners, and obstructed areas are checked, so they’re less effective for thorough hazard detection.
