RESCUE SYSTEMS 1 CHAPTER 13 THE RESCUE LITTER CHAPTER 13 - THE RESCUE LITTER The rescue litter, or Stokes basket as it is often referred to, has been the standard for victim removal over rough terrain for many years. It is designed for lifting and lowering the victim with a rigging system or for being hand carried. This device is not used by itself for spinal immobilization. It may be used, however, with other devices to achieve spinal immobilization. Due to its size, it is not easily used in a confined space or limited access area. This device is bulky and will require at least two rescuers to carry it to the victim unless it is transported by a rigging system. There are a variety of rescue litters designed for rescue work. The steel frame rescue litters are the most commonly used in the rescue field. Steel frame rescue litters can be found in different configurations. There are rectangular litters for accommodating large back boards, break-apart litters for ease of storage or carrying in the wilderness, split leg litters which limit the use of standard back boards, and plastisol-coated litters which have a rubberized coating for nonsparking and nonconducting requirements. Plastic rescue litters are typically not considered the best choice for rope rescue operations due to lack of structural durability. There are two basic types of plastic rescue litters. One type has a metal frame, which provides structural support designed for rope rescue operations. The other type has a metal top rail only. While suitable for water or snow rescues, plastic rescue litters generally are not suitable for rope rescue operations. Regardless of the rescue litters being used, their components need to be inspected prior to use.

Normal cleaning can be accomplished by using soap and water. Decontamination shall be done as per department procedures. Rescue litters should remain out of direct sunlight when not in use. VICTIM LASHING The victim lashing in a rescue litter consists of a pelvic lash and a chest lash, which is referred to as the interior lash. The interior lash keeps the victim from sliding out of the rescue litter at the head or foot ends. The exterior lash keeps the victim from coming out of the top of the rescue litter. All three lashes can be made with 20' lengths of webbing. Depending on the size of the victim different lengths of webbing may be necessary. In order to lessen abrasion to the lashing from other surfaces, do not wrap the main frame. Chest Lash 1. Before beginning the chest lash, the webbing used for the pelvic lash should be placed in the litter. 2. Lay a 20' piece of webbing across the litter with the middle at the point where the victim's crotch will be. 1. Form an 18" in the middle of a 20' piece of webbing and lay it in the litter so that the top of the loop is where the top of the victim's head will be. 2. Pass the loop over the victim's head to nipple line. 3. Wrap the webbing ends under each arm and pass through loop at chest. 4. Remove slack ensuring crossed webbing at victim's shoulder blades does not ride up on neck. 5. Tie an overhand knot in the webbing around the loop at the point it passes over the nipples on each side. 6. Tie a round turn and two half hitches at the ends of the webbing around a rib below the victim's waist where the rib meets the main frame. (Figure 13.3) - 116 - December 2000 RESCUE SYSTEMS 1 CHAPTER 13 THE RESCUE LITTER Figure 13.3 Litter, Chest Lash Pelvic Lash 1. Pull midpoint of webbing between legs up to victim's waist creating a 6" triangle. 2. Pass ends of webbing around thighs and through triangle pulling up towards shoulders to remove slack. 3. Tie an overhand knot in the webbing on each side at the point it passes through the triangle. 4. Tie a round turn and two half hitches at the ends of the webbing around a rib near the victim's shoulders where the rib meets the main frame. Figure 13.4 Litter, Pelvic Lash December 2000 - 117 - RESCUE SYSTEMS 1 CHAPTER 13 THE RESCUE LITTER Exterior Lash 1. Place a 20' piece of webbing across the victim's legs with the mid point at or below the knees. 2. Pass the ends of the webbing around the rib at or below the victim's knees on both sides where the rib meets the main frame. DO NOT WRAP THE MAIN FRAME! 3. Cross the webbing and pass the ends of the webbing around the next rib moving towards the head. 4. Repeat this operation until webbing passes around the ribs near the victim's shoulders. 5. Tie a round turn and two half hitches at one end of the webbing around the rib to secure the end. 6. Remove slack by pulling webbing from secured end toward free end. 7. Tie a round turn and two half hitches with the free end around the rib to secure the webbing. Figure 13.5 Litter, Exterior Lash RESCUE LITTER RIGGING The rescue litter can be rigged for horizontal lift, vertical lift, and low angle carry. To rig the rescue litter a commercial stretcher harness, rope pre-rig, or improvised pre-rig is required to connect the rescue litter to the rope rescue system. In this class, we will be using the rope pre-rig. Figure 13.6 Rope Pre-Rig Pre-Rig Construction Rope Pre-Rig (Two Are Required To Rig A Rescue Litter) 1. Tie a figure eight on a bight in the middle of a 16' rescue rope. 2. Tie a figure eight on a bight at the end of each leg of the pre-rig. 3. Attach a prusik loop above each figure eight on a bight with a three-wrap hitch. - 118 - December 2000 RESCUE SYSTEMS 1 CHAPTER 13 THE RESCUE LITTER 4. Attach a carabiner to the bight and the prusik loop on each leg of the pre-rig. Improvised Pre-Rig with Webbing (Two Are Required To Rig A Rescue Litter) 1. Tie a figure eight on a bight in the middle of a 20' length of webbing. 2. Tie an overhand on a bight 1' down from the center knot on each tail. 3. Pull the webbing ends through the same attachment points on the litter as those used for the rope pre-rig. 4. Pass the ends of the webbing through the overhand on a bight and adjust length so that the victim's head is slightly higher than the feet. 5. Tie off the ends of the webbing with two half hitches. Low Angle The low angle rescue litter rigging can be rigged for a three or a four-person carry. The number of litter tenders may depend on the victim's weight or available personnel. Three Litter Tenders 1. Rig a litter for vertical raising at the head of the litter. A 5' length of webbing is the preferred length for this sling. 2. Attach the figure eight on a bight knots in the end of the main and belay lines to an anchor plate or multi-directional ring with a steel carabiner. Figure 13.7 Litter Rigging, Low Angle, 3 Person 3. Attach the sling at the head of the rescue litter to the anchor plate with a steel carabiner. December 2000 - 119 - CHAPTER 13 THE RESCUE LITTER RESCUE SYSTEMS 1 4. Attach the center figure eight on a bight from one half of a pre-rig to the anchor plate. The ends of this half pre-rig are where the front two litter tenders will be attached to the system with carabiners to their pelvic harnesses. One rescuer will be positioned on either side of the litter. The prusiks attached to these tails will allow the tenders to better position themselves along the side of the litter. 5. Untie the middle figure eight on a bight in the other half of the pre-rig. This length of rope will secure the third rescuer at the foot of the rescue litter. Attach the figure eight on a bight and prusik loop at one end of this pre-rig to the anchor plate with a carabiner. Use a carabiner to clip the rope into the main frame of the litter at the victim's elbow. This will keep the rope from passing over the victim's body when it is attached to the rescuer at the foot of the litter. The rescuer at the foot of the litter uses the prusik at the end of the pre-rig attached to his pelvic harness to adjust his position. Four Litter Tenders 1. Rig a litter for vertical raising at the head of the litter. A 5' length of webbing is the preferred length for this sling. 2. Attach the figure eight on a bight knots in the end of the main and belay lines to an anchor plate or multi-directional ring with a steel carabiner. 3. Attach the sling at the head of the rescue litter to the anchor plate with a steel carabiner. 4. Untie the middle figure eight on a bight on each half of the pre-rig. 5. Attach the figure eight on a bight from the end of one half of a pre-rig to the right side of the anchor plate. The prusik hitch from this end and the figure eight on a bight at the opposite end of this half pre-rig are where the right front and rear litter tenders will be attached to the system with - 120 - Figure 13.8 Litter Rigging, Low Angle, 4 Person December 2000 RESCUE SYSTEMS 1 CHAPTER 13 THE RESCUE LITTER carabiners to their pelvic harnesses. The front litter tender will be positioned near the victim's shoulder. The rear person will be positioned near the victim's thighs. The prusiks attached to these tails will allow the tenders to better position themselves along the side of the litter. Use a carabiner to clip the rope into the main frame of the litter at the victim's elbow. This will keep the rope from passing over the victim's body when it is attached to the rescuer at the foot of the litter. 6. Attach the figure eight on a bight from the end of one half of a pre-rig to the left side of the anchor plate. The prusik hitch from this end and the figure eight on a bight and prusik at the opposite end of this half pre-rig are where the left front and rear litter tenders will be attached to the system with carabiners to their pelvic harnesses. The front litter tender will be positioned near the victim's shoulder. The rear person will be positioned near the victim's thighs. The prusiks attached to these tails will allow the tenders to better position themselves along the side of the litter. Use a carabiner to clip the rope into the main frame of the litter at the victim's elbow. This will keep the rope from passing over the victim's body when it is attached to the rescuer at the foot of the litter. Vertical Attachment Webbing Sling Method 1. Wrap a 5' length of webbing around the main frame at the head of the rescue litter. Beginning outside one of the skids and ending outside the opposite skid. Avoid weld in the middle. 2. Secure with an overhand bend. 3. Pull the webbing from the center of the main frame (at the weld point) until it reaches the end of the sling. 4. Rotate sling until knot is off to one side 5. Attach to rope with a carabiner clipped into figure eight on a bight. Figure 13.9 Litter Rigging, Vertical Raise December 2000 - 121 - RESCUE SYSTEMS 1 CHAPTER 13 THE RESCUE LITTER Direct Attachment to Rope Method 1. Tie a figure eight stopper knot about 3' from the end of the rope. 2. Wrap the end of the rope around the main frame at the head of the rescue litter. Beginning outside one of the skids and ending outside the opposite skid. Avoid weld in the middle. 3. Secure with a figure eight follow through with the end of the rope using the stopper knot. Figure 13.10 Litter Rigging, Vertical Raise, Improvised - 122 - December 2000 RESCUE SYSTEMS 1 CHAPTER 13 THE RESCUE LITTER Horizontal Attachment 1. A rope pre-rig is attached to the rescue litter with steel carabiners. 2. Carabiners clip around the main frame, between small rib (stops) provided to prevent carabiners from sliding up and down on the main frame. The carabiner gates go toward the inside of the basket. 3. The pre-rig is adjusted to keep the victim's head slightly higher than the feet or as patient care dictates.
