The pattern search helps prevent overlapping by dividing the area into smaller blocks. This statement is:

• A. True
• B. False
• C. Sometimes
• D. Not applicable

Answer: (A)

Pattern search uses a systematic approach to cover a collapse site by breaking the area into smaller blocks and searching each block in a defined sequence. This organization defines boundaries so teams don’t retrace the same ground, helping ensure every portion is checked and reducing duplication. While a little overlap between blocks may occur to confirm safety or adapt to irregular terrain, the primary purpose of the pattern is to prevent excessive overlapping and to deliver efficient, complete coverage. So the statement is true.
