Rope Rescue Confined Space Rescue Trench Rescue
Personal Protective Equipment for Specialized Rescue Operations Personal protective equipment – Structural fire fighting turnout gear worn by most fire fighters is often not appropriate for most rescue situations.
Personal Protective Equipment The type of fire fighting personal protective equipment that is most appropriate for Special Rescue would be a style that most resembles wildland fire fighters.
Personal Protective Equipment Helmet – regular structural fire fighting helmets are not recommended due to their size and weight so a hard hat style that resembles a wildland helmet but have chin straps and are specifically designed for rescue work.
Personal Protective Equipment Eye protection – in operations there are numerous opportunities for flying debris to enter the rescuers eyes.
Personal Protective Equipment Footwear Turnout boots are not recommended Leather boots which provide a good combination of function and protection. When selecting boots, ensure that is lightweight, has non-slip tread, provide ankle support, and be appropriate for the environment they are being used in.
Personal Protective Equipment Gloves – A medium-weight leather glove with reinforced palms are the best for rope rescue. They combine movement with good dexterity while giving good protection.
Qualifications of a Rescue Technician For certification, the rescue technician shall perform all of the job performance requirements in Chapter 5 of NFPA 1006 and all job performance requirements listed in at least one of the specialty areas.
Background Regulations- NFPA 1983, Standard on fire service life safety rope, harness, and hardware, is the primary standard covering the types of equipment used. The standard also covers the minimum performance standards for the life safety rope, harness, and hardware the rescuers use to support themselves and victims during actual or exercise rope rescue operations.
Background WAC Life Safety ropes, harnesses, and hardware protection. WAC Rope rescue operations. WAC Appendix B- Life safety ropes. See Handouts
Rope Rescue Equipment Rope Rope falls into two classifications: a. Life Safety b. Utility
Rope Rescue Equipment Life safety rope is used to support rescuers and victims during an actual incident or training. Utility rope is used for hoisting tools and equipment.
Rope Rescue Equipment The inspection of the rope shall be performed before the rope is put in to service, also before and after each use to ensure that the rope has not been compromised.
Rope Rescue Equipment The following items below should be considered before the life safety rope is put back in use. 1. The rope has not been visibly damaged 2. The rope has not been exposed to heat, direct flame impingement, or abrasion. 3. The rope has not been subjected to any impact load
Rope Rescue Equipment 4.The rope has not been exposed to liquids, solids, gases, mists, or vapors of any chemical or other material that can deteriorate rope 5.The rope passes inspection when inspected by a qualified person using the manufactures specifications
Rope Rescue Equipment Life safety rope is generally ½ “ in diameter and of kernmantle construction. The minimum breaking strength for two-person rope is 9,000lbs. The maximum working load for life safety rope is the maximum amount of weight that may be supported by the rope in use.
Rope Rescue Equipment There has traditionally been two types of rope used in life safety situations. Dynamic rope Static rope
Rope Rescue Equipment Dynamic rope is used when long falls are possible like in a rock climbing situation due to it’s high elasticity Dynamic rope is designed to stretch up to 60% of its length without breaking
Rope Rescue Equipment Static rope is the rope of choice for most rescue incidents. It is only designed to stretch 20% of its length before breaking thus it is better suited for heavy haul applications
Rope Rescue Equipment Life safety rope logs The log tracks the use and maintenance of that piece of rope and will help determine when to retire the rope.
Rope Rescue Equipment Webbing Flat webbing Mainly used in rescue work for straps and harnesses. Tubular webbing Most commonly used webbing in the fire service
Rope Rescue Equipment Harness Class I – fastens around the waist, and is intended for emergency escape for one person. Class II – Fastens around the waist and around the thighs and may be used in two person rescues Class III – Fastens around the waist and thighs and also over the shoulders. It is designed to support two-person loads
Rope Rescue Equipment Hardware – Mechanical devices needed to fully and safely utilize rope rescue and to construct mechanical advantage systems The following are types of hardware
Hardware Carabiners Consist of a metal loop with a hinged gate to close the opening
Hardware Rescue Ring Steel ring specifically designed for rescue applications
Hardware Rigging plates Used for attaching systems or multi- directional loads
Hardware Figure 8 plates consists of a double ring of steel or anodized aluminum, with one ring larger then the other
Hardware Brake Bar Rack Repelling device using a U-shaped rod with six friction bars between
Hardware Pulleys Single-sheave, Double-sheave
Hardware Edge rollers
Knots To use the equipment just described in the last section, rope and webbing must usually be tied into knots See Handout
Knots Becket bend

Systems Anchor systems – Provides a safe and dependable means of securing the rescue rope to a “bomb proof” anchor point. The most common types of anchor systems used are single point, and load sharing.
System The most common type of single point anchor is the tensionless anchor.
Systems Load sharing anchors are used when there is doubt about the anchor point being able to carry the expected load. Load sharing anchors also distribute the weight between two different points.
Systems A third type of anchor is the self adjusting anchor point. This is used when the load point is expected to change direction of pull. In a multi anchor system the critical angle must be watched so that it does not exceed 120 degrees. The optimal angle is 90 degrees.
Systems Mechanical advantages – Various types of hauling systems using rope, pulleys, carabiners, and webbing. Mechanical advantage systems are broken into two groups simple and compound.
Systems 1. Simple systems Simple systems are your 4:1, 3:1 systems. 2. Compound systems Compound systems are when one simple system is attached to another to multiply the mechanical advantage. One disadvantage to the compound systems are that they take a lot of rope.
Any Questions About Ropes?
Confined Space Rescue Awareness Confined space Is large enough and so configured that an employee can bodily enter and perform assigned work. Has limited or restricted means for entry or exit. Is not designated for continuous occupancy
Confined Space Rescue Awareness Permit required confined space In addition to meeting all the criteria for a confined space, have one or more of the following: Contains or has a potential to contain a hazardous atmosphere. Contains a material that has the potential of engulfing an entrant. Has an internal configuration such that an entrant could be trapped or asphyxiated by inwardly converging walls or by a floor that slopes downward to a smaller cross section. Contains any other recognized safety hazard.
Confined Space Rescue Awareness Permit required confined space The written entry permit must be posted at the entry point and Must list more than a dozen essential items of information about the space. Work to be done in the space Who will do it
Confined space hazards Environmental Hazards Darkness Temperature extremes Noise Moisture Dust
IDLH IMMEDIATELY DANGEROUS TO LIFE OR HEALTH Any condition which poses an immediate threat to the health of life on an entrant, or; Would cause irreversible adverse health effects, or; Would interfere with an individual’s ability to escape unaided from a permit space.
CONTAMINANTS: ROUTES OF ENTRY l Inhalation l Ingestion l Absorption Injection
Always test the air at various levels to be sure that the entire space is safe. Good Air Poor Air Deadly Air Good air near the opening does NOT mean there is good air at the bottom!
Confined Space Rescue Awareness PPE requirements
How important is your attendant?
Tactical considerations Phase 1: Assessment on arrival Primary assessment (size-up) Information gathering How many victims- are they injured or merely trapped? How long have they been down? Are they conscious and if so can they communicate? Are they all in the same confined space? Is there an entry permit available?
Tactical considerations Decision Making Contact victim Interview witnesses Examine permits Monitor atmosphere within the space Identify hazards Evaluate what has been done and is being done Weigh risks vs. benefits of available options Evaluate adequacy of initial response Contact expert assistance from Operations or Technician level experts
Tactical considerations Secondary assessment (size-up) Type of space Condition of space Contents of space Mode of operation- rescue vs. body recovery
Tactical Considerations Phase 2: Pre-Rescue Operations Finalizing the incident action plan Gathering the necessary resources- both personnel and equipment Monitoring and managing the atmosphere inside the space Oxygen concentration Flammables Toxics Ventilation through mechanical means
Tactical Consideration Making the space structurally stable enough to enter Lockout/Tag out procedures Internal hazards Shoring Lighting
Tactical Considerations Ensure that there is adequate communications capability to allow the action plan to be carried out safely Voice communication Lifeline Hard-wired phones Portable radios
Tactical Considerations Phase 3: Rescue Operations Personnel should be prohibited from entering except to assist trained rescuers Accountability of team members Search Victim treatment/stabilization Victim removal
Tactical Considerations Phase 4: Termination Equipment retrieval vs. equipment abandonment Investigation- review and critique the operation Release of control Critical Incident Stress Debriefing
Any questions about confined spaces?
Trench Rescue Awareness Definition of a trench
A trench according to OSHA
Not a trench
Types of collapses Slough-in Sidewall-in Shear-in Spoil-in
Shear-in AKA: Lip-in
Spoil-in To prevent a spoil-in the spoil pile is to be at least 2 feet from the lip and laid back less than 45 degrees
What hazards could you encounter in this environment?
Trench Rescue Awarenes Trench rescue hazards Physical hazards Secondary collapse Bulges in trench wall Horizontal cracks or fissures in trench wall Loose chunks falling from trench wall Water seeping into trench Loose material suddenly falling from the lip of the trench Unstable Debris Unsupported utilities
Tactical Considerations Phase 1- Assessment on arrival Information gathering have all workers been accounted for how many victims are there is their location known are they fully or partially buried how much time has elapsed since cave-in what has been done so far
Tactical Considerations Decision making Can the units on scene or en route handle the situation? Do additional units need to be called?- call them immediately He first-in officer MUST assume command and begin to form an IAP
Tactical Considerations Scene control Isolate the area of the collapse- establish hot, warm, and cold zones Shut off all vehicles and prevent traffic within 300 feet of the trench
Tactical Considerations Secondary Assessment Type of soil- may have to rely on workers at the scene Condition of trench What type of cave-in occurred? Did one or both walls collapse? What type of shoring will be needed? Are there hazards in and around the trench? Mode of Operation- rescue or recovery?
Tactical Considerations Phase 2- Pre-rescue Operations Incident action plan-MANDATORY Backup plan should be available Gathering resources- the sooner they are called, the sooner they will get there. Call for everything that might be needed. Personnel- specially trained Equipment- specialized
Tactical Considerations Ventilation Positive- blowing fresh air into the trench Negative- draw contaminants out Preparing the scene Mitigating hazards- such as leaking gas or water pipes and electrical lines Fire protection- hose lines or extinguishers on stand-by Shoring Ladders- should be placed at both ends of the protection system, no farther than 25 feet apart
Tactical Considerations Phase 3- Rescue Operations Personnel accountability Search/rescue Personnel should not enter the trench unless assisting properly trained rescue personnel
Tactical Considerations Phase 4- Termination Equipment retrieval Identifying/collecting Dismantling Investigation- review and critique Release of Control Critical Incident Stress Debriefing
