When is the greatest chance of survival for trapped victims?

• A. First 24 hours
• B. First 72 hours
• C. During nighttime
• D. After 24 hours

Answer: (A)

Survivability after a collapse is highest when help arrives quickly. Immediately after the event, a trapped person may still have breathable air, manageable heat, and the potential to be extricated before serious injuries or medical deterioration set in. The chances of successful rescue depend on rapid search, access, and medical stabilization before conditions inside the rubble worsen—dehydration, hypoxia, crush injuries, and shifting debris can rapidly reduce life expectancy. As time passes beyond the early hours, the window for a live rescue narrows and the environment becomes more hazardous for both victims and rescuers. Nighttime can complicate operations, but it does not improve survival odds; the primary factor is how much time has elapsed since the collapse. So the best chance of survival for trapped victims is within the first 24 hours.
