In a zone and sector search, which description is correct?

• A. Large buildings/outdoor areas divided into sectors; start at the far side of the incident.
• B. Large buildings/outdoor areas divided into sectors; start where incident occurred.
• C. Small rooms only; no exterior search.
• D. Outdoor areas only; interior spaces excluded.

Answer: (B)

Zone and sector searches organize a large area by dividing it into manageable sections so each team can systematically cover everything without overlap. The best description matches this approach by saying large buildings or outdoor areas are divided into sectors, and you begin your search at the location where the incident occurred. Starting at the origin ensures that hazards or victims near the source are found quickly, allows immediate assessment of the incident’s primary conditions, and provides a logical progression as teams move outward into adjacent sectors. It also supports clear accountability—knowing exactly which sector each team is responsible for—so nothing is missed. Starting at the far side of the incident would risk delaying critical actions at the source, potentially missing hazards or victims right where they started. Focusing only on small rooms would ignore exterior areas that may contain hazards or victims, and excluding exterior spaces would leave large areas unchecked.
