Final answer:
To safely climb trees and avoid incidents, you should use a harness with pouches or a secured backpack to carry equipment.
Step-by-step explanation:
When climbing up and down a tree, it is critical to use equipment specifically designed for carrying items safely. This equipment might involve a harness with pouches or a backpack that securely attaches to your body. Doing so ensures that your hands are free to hold on to the tree, reducing the risk of an incident. It's crucial to avoid carrying items in your hands, which could lead to drops or falls, potentially causing injury to you or others below. Safety should always be a priority, and this notion extends to assuring that you have other essential items such as water, sunscreen, and an emergency first aid for any outdoor climbing activity.
