Which of the following is NOT a type of search pattern?

• A. Spiral
• B. Grid
• C. Random
• D. Zone/quadrant

Answer: (C)

Systematic search patterns are used to ensure every area is covered and actions are traceable. A spiral starts at a point and moves outward in expanding rings, ensuring nearby areas are checked in a logical sequence. A grid divides the area into lanes in two directions, allowing thorough, repeatable coverage and easy recording of what has been searched. Zone or quadrant patterns split the space into named sectors, making coordination and safety management more straightforward by assigning each sector to team members. Random, on the other hand, has no predefined path, so it can miss spots, duplicate effort, and make it hard to document where searches were conducted.
