Stretchers in tree worker rescue
Vertical rescue technicians are trained to place casualties in stretchers to package for extraction .
In aerial tree rescue this system may not be effective :
• It can be difficult or impossible to effectively position and support a stretcher within the branch structure of a tree ’ s crown .
• It is challenging for enough rescuers to be ‘ in position ’ to manage the transfer of the casualty into the stretcher .
• A rapid , vertical descent is almost always possible in tree rescues . Placing the casualty in a stretcher may make it harder rather than easier to navigate the lower branch structure of the tree .
A rapid extraction to the ground is usually preferred , followed by packaging the casualty on the ground if needed for any subsequent extraction from site . For temporary casualty support during the descent , the use of a chest sling is normally preferred .
A casualty may be lowered directly from the tree into a stretcher placed ready on the ground below the tree . This is the best use of the stretcher and the most efficient use of time to rescue a casualty suspended in a tree .
Use of stretchers with rescue elevated work platforms .
Stretchers are very effective when used in conjunction with rescue EWP ’ s and other rescue appliances .
The stretcher can be installed on the platform extension prior to commencement of the rescue and the casualty can be ‘ scooped ’ by bringing the platform and stretcher directly upwards from below .
