Kid is out camping/hiking/hunting
At some point decides to climb hydro tower
Option 1) Victim is electocuted and falls, on his way down he bangs off various pieces of metal. When he lands he lands on what?

Option 2) same as above but no electricity.

Possible injuries;
Electrical burns or other injuries
Fractures
Internal bleeding
Open wounds i.e. sucking chest, exposed internal organs such as intestines.

Twists
penetrating wound to underside of victim if rescuer doesn't do a proper exam.
Weather - cold, snow, freezing rain, hypothermia
penetrating wound such as impalement on large object that may require cutting
victim could be entangled in structure requiring lowering, if you can't do that option maybe you find him between trees, rocks ect that may require him to be taken out of. Similiar to a scenario where you use desks and chairs to simulate an auto accident

REAL TWIST
You find out he was in the tower because he was escaping graboids, NOW WHAT DO YOU DO

Incident involving heavy equipment such as a skidder
Unconsious or wounded victim that is located on a rock in a fast flowing river, rescuers have to remove victim without their assistance

I witnessed this one for real but it happened to a dog not a person.
Diver leaves speargun leaning against a log, victim jumps over log and impales themselve on the spear point.
