In certain situations, it may be essential for crew members to aid in the safe descent of a climber. Various systems and techniques can be employed to achieve this objective. The fundamental principle of ground-assisted rescue is that team members possess the ability to securely lower an individual from an elevated position, ensuring they are placed in a safe, appropriate, and comfortable location.

Spur climbing is a widely utilized method for ascending trees, particularly for removal tasks. The scenario of a spar pole rescue is a realistic situation that merits practice, as many tree service companies regularly engage in such removals. Rescuing an individual who is incapacitated while using spurs presents distinct challenges. A primary concern is lifting the weight of the individual off the spurs, which can frequently become embedded deeply in the wood.

If the life support system of the patient climber is compromised or absent, the rescuer may need to either establish a new system, restore the existing one, or execute a pick-off technique. Prior to undertaking any of these actions, several critical factors must be considered, including additional weight, friction management, and the overall functionality of the system. During a pick-off, the rescuer will secure and load the patient directly into their own system. While pick-offs can be efficient, failing to adhere to proper protocols and techniques can significantly increase risks for both the rescuer and the patient. If a pick-off is not feasible, transferring the patient to a separate system may be a more prudent choice. This process involves bringing in an additional system that can be safely installed and then connected to the patient climber. Alternatively, if the rescuer determines that the patient’s current system components are functional and safe, simply reconfiguring and reinstalling the existing system may be an appropriate solution.

A climber becoming trapped and pinned can happen in various environments, not solely while aloft in trees. When such incidents take place in a tree, the rescue protocol faces specific challenges. The climber may be pinned or crushed by debris, machinery, or other objects. Ensuring the stabilization of both the individual and the object is crucial for the health of the patient, as well as the safety of the rescuers and their team. It is vital not to hastily remove any object that is compressing or pinning the patient, as this could lead to a sudden deterioration in their condition. Without appropriate medical interventions readily available, this could significantly decrease the chances of survival. In situations where a person is trapped and pinned, adhering to the protocols established by a higher medical authority regarding the timing and method of object removal is essential. Rescues involving trapped and pinned individuals present a range of unique and complex challenges, often requiring a highly coordinated response, which complicates preparation efforts.

A climber may find themselves significantly distanced from the central tie-in point or another tree, creating a challenging scenario. This situation can complicate the rescuer's access line, which, while close to the patient’s tie-in point, remains far from the patient’s actual location. In a re-directed rescue, it is crucial for the climber to assess the angles and loads affecting the anchor points that provide life support. Various techniques can be employed to safely and effectively redirect and transfer either the rescuer, the patient, or both to a designated area. This process often involves horizontal redirection or transfer along a system in a controlled and secure manner. Re-directed rescues are particularly useful for establishing contact with a patient when the climber is positioned at a considerable distance from the rescue access line. Additionally, this method can facilitate the horizontal transfer of the patient down a system, which is beneficial for evacuating areas where a direct vertical descent is not feasible.

It is crucial to evaluate the canopy and tree species in the context of an arborist emergency rescue situation. Various tree species possess distinct structural characteristics, which can influence the effectiveness of the rescue operation. Always ensure that these factors are taken into account prior to initiating the rescue. This includes the final two scenarios, open and confined canopy rescue.

To effectively practice and prepare, a climber must possess an understanding of all mentioned various rescue scenarios and principles. This knowledge will enhance decision-making during an arborist rescue emergency. Sound judgment is crucial for ensuring the safety of all involved and for the successful execution of a rescue operation.
