How often should you rotate teams during operations?

• A. Every 2 hours
• B. Every 15-30 minutes
• C. Every 60 minutes
• D. Every 5 minutes

Answer: (B)

Maintaining safety and performance in hazardous environments relies on timely team rotations to prevent fatigue and loss of situational awareness. In structure collapse operations, crews face shifting hazards, limited air, and intense physical demands. Turning teams over every 15 to 30 minutes keeps at least one team fresh enough to continue critical tasks, perform quick hazard assessments, and uphold communication and coordination with the rest of the crew.

This interval also fits with rehab needs—water, rest, hydration, and equipment checks—without sacrificing progress. Rotating too infrequently (like every hour or more) allows fatigue to erode decision-making and stability, while rotating too often (every few minutes) disrupts continuity and productivity. So, a 15- to 30-minute cycle strikes the right balance between safety and mission advancement.
