(2) If the casualty is lying on his stomach, keep him from moving until
medical help arrives. If the casualty is lying on his back, use padding to help immobilize
his back, neck, and head as described below.
(a) Roll or fold padding (such as a blanket) so that it conforms to the
shape of the arch of his back. Then carefully slide the padding under the arch of his
back. This padding will help to support and immobilize his back.
(b) Prepare and slide a roll of cloth under the casualty's neck to help
support and immobilize his neck. Figure 6-2 illustrates padding supporting a casualty's
back and neck.
Figure 6-2. Padding placed under a casualty's back and neck.
(c) Place padded rocks, small padded logs, or filled boots on each side
of the casualty's head to keep it from moving (figure 6-3). Filled boots are prepared by
removing the casualty's boots, filling the boots almost to the top with sand or small
rocks, place material (strip of clothing, sock, etc.) on top of the sand or rocks, and tying
the top of the boots to keep the material and filler from coming out.
Do not remove the casualty's boots if you are in a chemical environment.
