Technical Rescue Field Operations Guide How to use this guide A stop sign icon indicates a hazard warning where improper technique may result in serious injury or death. 3 Text with a red check next to it denotes a key part of that specific procedure. 3 Text with a red check and colored red denotes a critical aspect of that procedure that must not be overlooked. !Red rope in this guide denotes working line. Belay line has no fill or is grey. On checklists: A black box indicates an operational level skill A red box indicates a technician level skill 3Remember that this is only a guide. The rescuer must adapt to each situation as common sense dictates! 3Always be sure the system passes the whistle test, which means if all rescuers were to let go of the systems, no catastrophic failure or injuries would occur. 3Always be sure all personnel tie in near the edge. *Metric measurements are included in parentheses in the rope rescue section and are converted to the nearest centimeter or half meter.

2 NFPA 1670 Standards NFPA 1670 1999 edition is the current standard for technical rescue operations. Skills and procedures in this guide are categorized according to NFPA 1670 standards where applicable. For example, a command checklist involves scene size-up and hazard recognition. This is an awareness level skill and will have an icon. High angle litter raising is a technician level skill and will have a icon. Some procedures are not specifically addressed in the NFPA standard and the categorization is interpreted from similar categorized procedures. An interpreted level will have an asterisk next to the icon. The intent is to make it easy for responders to assess different situations appropriately and to train according to standardized guidelines. The general definitions of the 1670 operational levels are in Appendix A. Refer to the NFPA 1670 document for complete definitions in each area and for each skill or procedure. The authority having jurisdiction has final say as to the categorization of each procedure. Awareness level skill Operational level skill Technician level skill NFPA 1983, 2001 Edition NFPA 1983 is the U.S. Fire Service standard for life safety rope and harnesses. It defines all rescue system components, their construction, use, labeling and testing. A two person system icon means that the procedure is intended for two person loads and any component that will bear the weight of two people must be rated for general use. Light duty components may be part of the system when they are used to support the weight of a single person. Two person (general use) components |

Risk Management Safety is always our first concern At the start of each operation, ask these questions; 1. What is the key problem? 2. What is our plan of action? 3. Why is that the safest plan? 4. What are the biggest risks that we need to watch out for? 5. What is your gut feeling about this plan? Remember _ We will risk our lives in a calculated way that is appropriate to the situation to save savable lives _ We will not risk our lives at all for that which is already lost Communicate _ Each operation must have a clearly defined leader _ A decision on rescue or recovery strategy must be made clear to everyone at the outset of every operation _ Speak up if you see a problem no matter how small or obvious it may seem Re-evaluate strategy whenever appropriate _ When new information becomes known _ When a significant event occurs _ After an extended time period has elapsed |

4 Incident Management Most technical rescue incidents are focused around a small number of subjects and can be easily handled with a simple Incident Command System (ICS) structure. Overall command can be any officer but a rescue technician should assume an operations level role and manage the technical rescue portion of the incident. Each discipline has a specific command checklist with key tactical benchmarks. Use the checklist. First Responders _ Take command and size up _ Focus on information gathering _ Identify hazards _ Be certain that the right resources are called early _ Avoid activities marked in red on checklists and in text Rescue Technician/Operations Officer (TSO) _ Assume operations control _ Review hazards and critical factors _ Assist with the formation of incident action plan and backup plan _ Assign sectors and deploy resources _ Keep command informed about all phases of the operation _ Communicate with sectors and revise plans as needed Rescue Technician/Sector Officer (i.e. Rescue Sector) _ Clearly understand the action plan _ Communicate the action plan to sector personnel _ Supervise task level activities _ Keep Operations Officer or Incident Commander updated on a regular basis Technical Sector Officer (TSO) is normally a term for the person in charge of a group or sector (i.e. Rescue Sector). In some cases the TSO may function as the overall rescue leader. |

Incident Management Mountain Rescue example Public Information Safety Command Liason Other sectionsOperations (TSO) Recon Rescue Treatment Extrication Landing Zone (LZ) The Operations Officer should be an experienced rescue leader. The Operations Officer will work with the Incident Commander to develop the incident action plan (IAP). The Operations Officer will be responsible for carrying out the IAP. Recon should be a light, fast two or three rescuer group. Their primary goal is to get physical contact with the subject and report to operations. The Technical Sector Officer has the tactical goal of removing the subject from the hazard area. They must coordinate the set- up and operation of the technical evacuation system. Recon can be re-assigned as treatment sector once they have gained access to the subject and begun stabilization. Extrication is a Technical Sector Officer who can be assigned to coordinate the next phase of transporting the subject to the Command Post. Landing Zone (LZ) Controller is a Technical Sector Officer who coordinates the set-up, operation and safety of the helicopter landing zone and any rigging and transportation performed by helicopter. 5 |

6 Time Management Time is a critical factor. History has proven that performing tasks sequentially to accomplish the objective consumes the greatest amount of time. Tips for a safe and fast rescue _ The Technical Sector Officer (TSO) has the big picture, coordinating and fine tuning all parts of the technical evacuation sector _ Multitasking with simultaneous performance of tasks is the goal _ Individuals must work as quickly as possible to accomplish their task, but must not compromise safety for speed _ The TSO must avoid performing hands-on tasks in order to retain overall control of the sector _ Frequent operation specific training is necessary for a safe, effective and efficient team Safety Attendant Working Line Belay Line TSO Edge Treatment |

Sizing Personal Purcells Harness loop navel to top of head Long leg loop cinched tight on boot to navel Short leg loop cinched tight on boot to upper third of thigh3These prusik lengths are approximate and will vary from individual to individual based on anatomical reference points and personal preference. The harness loop must be long enough to prusik onto the rappel line above the descent device and clip into your harness. Rope Rescue Purcell Prusik System 17 |

Rope Rescue Self Rescue 18Self Rescue A rescuer must always be prepared to perform self rescue procedures, specifically the ability to ascend a fixed rope, free a jammed descent device, pass a knot on rappel or any combination of the above. Warning! The belay rope has been left out of this illustration for clarity and also to make the point that in a self rescue situation a belay might not be available. Extremecaution is warranted when there is no belay. An option is to tie a bight into the rope below the leg purcell and clip it to the harness. Tie a new bight every 5 linear ft. (1.5m) of rope climbed and clip to harness. 3Always use a second rope belay whenever possible! Ascend fixed rope 1. Attach harness prusik loop to rope with prusik hitch. 2. Connect harness loop to harness with locking carabiner. 3. Attach climbing purcell to rope with prusik hitch. 4. Place foot into small loop and cinch tight onto foot. 5. Sit back onto harness prusik and move climbing prusik up toward harness prusik with free hand. 6. Stand up onto climbing prusik and move harness prusik up as far as possible. 7. Repeat this process until reaching destination or until problem is solved. ! |

Patient Packaging The following five points should be patient packaging goals. 1. Immobilize the patient to minimize movement no matter what position the litter is placed in. 2. Use plenty of padding under the patient and in all voids. 3. Protect the head and face from debris and vegetation. 4. Protect the patient from the elements both hot and cold. 5. Give special consideration to vital signs and airway management. Leave buffer space between the patients head and the end of the litter 15 ft. (4.5m) (Red) webbing has no tension. Used as restraint precaution to prevent patients head from pushing against end of litter. 20 ft. (6m) webbing for seat and upper body 30 ft. (9m) webbing for feet and lower body Pad all void areas Modify packaging if needed for injured extremities Commercially made strap systems also work well Cold weather Use a three layer system. 1. Vapor barrier against skin. 2. Insulation layer. 3. Weather barrier. Heat packs must be added if the patient is hypothermic or if the evacuation will take longer than 30 minutes.3This illustration is but one example of a number of techniques that can be used.

Rope Rescue Low Angle Evacuation 20 Low Angle Evacuation 0- 40 _ Majority of weight on ground _ 4 to 6 bearers _ Litter wheel optional depending on terrain _ 15 ft. (4.5m) carry strap for each bearer optional _ Single belay line optional depending on terrain _ Use tandem prusik for belay _ Do not load belay line or use to lower Apply litter wheel to head 1/3 rd of litter Six bearers are used when the wheel is not practicalAttach 30 ft. (9m) webbing to litter head for dynamic belay Caterpillar pass _ Consider caterpillar pass to negotiate short sections of technical terrain _ Get solid footing and stay in position while passing litter hand to hand _ Very effective on short sections of steep and high angle obstacles _ This is an effective technique but at least 10 or 12 bearers are desirable to accommodate personnel rotation _ Consider belay line |

Anchor Systems Definitions _ Natural anchors: naturally occurring trees and rocks _ Artificial anchors: anything placed by man including fire trucks and structural members _ Bombproof anchor: an anchor that you confidently believe will hold the intended load and any potential impact force unintentionally generated by the load _ Marginal anchor: an anchor that you do not believe to be bombproof _ Single-point anchor: single point of origin _ Multi-point anchor: a collection of marginal point anchors connected into a bombproof anchor system _ Back-tie anchor: a marginal anchor in a good location that is linearly connected with a tensioning unit to a bombproof anchor somewhere back from the edge Concepts _ Safety test all anchors in the direction of use with a force comparable to the working load _ Watch for signs of weakness or failure _ Distribute force equally between all anchors in a multi-point system _ On multi-point anchors, keep the distributing link small to minimize any potential impact force _ Always try to have independent anchors for the working line and belay line _ Choose strong points like joints and corners on structural members for anchors _ Avoid mid-span anchor points on structural members if possible _ When using pre-sewn straps, prevent side loaded or tri- loaded carabiners Rope Rescue Anchor Systems 21 |
|
Rope Rescue Anchor Systems 22 Anchor Systems _ Keep angle less than 90 _ Commercially made straps are acceptable _ Commit entire ropes to the anchor if necessary _ Pad all sharp edges High strength tie off Anchor extension, as long as necessary Wrap three pull two point anchors 1 in. tubular webbing Distributing link; keep as small as possible to minimize potential shock load Collection point (anchor plate) Overhand knot encompasing all loopsThree point, load distributing, multi-point anchor system (potential shock-load) Two point, load sharing, multi-point anchor system (minimizes shock-load) 3Always double-check everything! |

Back-Tie Anchors A back-tie anchor is used to focus a marginal anchor to a bombproof anchor. It is built with low-stretch rope and a system prusik. 1. Construct back-tie system as shown with ratchet prusik on line closest to haulers. 2. Three wraps of 1/2 in. (13mm) rope is ideal but distance between anchors and available rope may limit number of wraps. 3. Pull tension on system and set ratchet so that all ropes stay under tension but do not damage forward anchor. 4. Tie off back-tie tension unit. System attachment point Interwoven wrap 3 pull 2 Ratchet prusik on haul side Wrap 3 pull 2Bomb- proof anchor 3:1 without pulleys Tie off with double overhand on a bight 3Keep back-tie anchor in line with the fall line. 3As a rule, look for bombproof single-point anchors and linear anchors for rescue. 3Multi-point anchor systems made of marginal anchors should be the rare exception.

Rope Rescue Directional Anchors 24 Directional Anchors The fall line refers to the natural plumb line always present as a result of gravity. It is affected and changed by the angle and aspect of the slope. The location of suitable anchors relative to a suitable fall line is always a critical factor. Occasionally, it is safest to redirect the system into a directed fall line with a directional anchor. Caution: a change of direction can place up to 200% of the load on the directional anchor depending on the vector angle. A 90vector angle will place approximately 140% of the load on the directional anchor. Main anchorDirected fall line Directional anchor Original fall line Vector angle Change of direction |

Rope Rescue Belays 26 Fixed Belay for Edgemen Edgemen must have two points of contact while working near the edge. The rescuers feet count as one point provided the rescuer does not intend to put body weight on the belay line and that the edge is not sloping. An unweighted belay line is required if the edgemen intend to put body weight on their primary restraint. Personal anchors Fixed line Wrap 3 pull 2 Munter Hitch belay tied off with overhand knot or manned by belayer High strength tie offBelay line Fixed line Short purcell prusiked onto fixed line as primary attachment point Separate line to secure edge protection |

Tandem Prusik Belay Operation Lower 1. For lowering system, place one hand on both prusiks and create a z-turn with the rope on the load side with the otherhand. 2. Hold the z-turn and let rope out 1 to 2 ft. (~.5m) or 2/3 arm length. 3. Begin to turn z-turn hand while feeling and maintaining the tension on the rope. 4. Quickly move the z-turn hand back toward the prusik hand and make another z-turn. 5. Repeat this process always keeping a feel for the rescue package. Raise 1. Pull constant tension on the free end of the belay rope. 2. Let the prusik minding pulley (PMP) mind the tandem prusiks. |
