If there is a victim in the water, what is a safe assumption about the ice?

• A. The ice is very thick.
• B. The ice is moderately thick.
• C. The ice is irrelevant.
• D. The ice is weak.

Answer: (D)

When there’s a victim in the water, you must treat the ice as weak. The presence of water under or on the ice indicates structural failure zones and reduced strength, especially around the area where someone has fallen through. Water on or near the surface lowers the ice’s load-bearing capacity, and cracks or slush can propagate quickly. Adding any weight from rescuers or equipment makes collapse even more likely, so the safest assumption is that the ice is weak.

This isn’t about guessing thickness; a very thick-looking surface can still be compromised where cracks and water are involved. Saying it’s thick or moderately thick would ignore the risk signaled by a person in the water, and saying it’s irrelevant would ignore the clear safety cue. Treat the ice as weak and use safer rescue methods that don’t require stepping onto suspect ice.
