Which crew-rotation arrangement minimizes simultaneous relief of hands-on rescuers?

• A. Part
• B. Overlapping
• C. Sequential
• D. Rotational

Answer: (B)

Overlapping rotation keeps a transition window where both the outgoing hands-on rescuers and their replacements are on scene at the same time. That built-in overlap lets relief happen in small, staggered steps rather than as one big block. By spreading relief over time, you maintain continuous scene protection and reduce the chance that a large number of rescuers are taken off active duty at once, which helps manage fatigue, maintain situational awareness, and preserve rescue capability in a dynamic collapse environment. Other patterns tend to pull people off duty in larger blocks or without a controlled overlap, increasing the potential for coverage gaps and fatigue-related errors.
