What can be used as improvised poles for carrying a casualty?

Strong branches are an effective choice for improvised poles when carrying a casualty due to their natural sturdiness and availability in many environments. Branches from trees can often support significant weight and provide a firm structure for lifting and transporting a person who is injured or unable to move. Their natural shape can also allow for comfortable holding points, which can be critical when maneuvering a casualty through various settings.

While other materials like fencing material and plastic rods might seem practical, they may present challenges such as being less readily available in a natural setting or lacking the necessary strength and support needed in a rescue scenario. Clothes hangers, on the other hand, are generally too flimsy to provide the needed support for carrying a casualty safely. Thus, strong branches emerge as the most reliable and accessible option for this purpose.
