A webbing sling is used primarily to provide grip around which part of a victim’s body?

The use of a webbing sling is primarily focused on providing a secure grip around the victim's upper body. This design allows rescuers to effectively secure and lift the victim while minimizing the risk of injury. The upper body includes key areas such as the torso, which helps in maintaining balance and stability during the rescue operation.

Focusing on the upper body allows for better control when performing extrications, especially in challenging or rugged environments where support and maneuverability are critical. Ensuring the webbing sling is correctly positioned across the upper body also aids in distributing the weight evenly, which is essential for safety during lifting and carrying processes. This technique is particularly useful in situations involving spinal injuries, as it allows rescuers to stabilize the victim while extracting them from a hazardous location.

Other body parts such as the legs, head, or waist might not provide the same level of stability, control, or safety during the lifting process, which is why securing the upper body is the preferred method.
