The shoulder straps of the middle or two middle rucksacks should be released, which
may require cutting the security seams at the ends of the straps.
Figure 7-2. Single rucksack technique for carrying an injured person
The shoulder straps of each rucksack except the top one should be run through the
shoulder straps of the one above it and reattached ( Fig. 7-3 ).

The person to be carried should be placed flat on the stretcher. Lifting by clothing may
be easiest. The person's head can be placed between the upper ends of the straps of the
first rucksack or can be stabilized by the waist belt of the lowest rucksack. If the person
is unconscious, the neck should be stabilized with a SAM Splint®.
