Final answer:
All of the items listed, including a map and compass, whistle, and cell phone, would help rescuers to locate someone who is lost on the trails.
Step-by-step explanation:
The items that might help rescuers find someone who gets lost on the trails are all of the above: a map and compass, a whistle, and a cell phone. A map and compass can help rescuers determine your last known location or planned route.
A whistle is useful as it can provide an audible signal that can be heard from far away, especially if the lost person is unable to shout. Lastly, a cell phone can be a critical tool for communication; it can send and receive messages, and in some cases, provide location details to rescuers. Together, these tools improve the chances of a successful rescue.
Hydraulic rescue tools date back to the early 1960s when they were first developed to speed up the process of freeing racing car drivers from crashed vehicles.
Today, they’re used by fire and rescue teams in response to emergency incidents, such as roadside accidents and building collapses. When working on life-changing emergencies there’s no time to lose. So having a wide selection of powerful hydraulic tools to cope with just about any emergency could be the difference that saves a life.
