1 Confined Space Rescue

2 CONFINED SPACE RESCUE INSTRUCTIONAL GOAL  The participant will understand the need for an efficient and coordinated response to a confined space rescue operations.

3 ENABLING OBJECTIVES  List five priorities for emergency rescue operations.  Explain the three types of confined space rescue.  Identify specific rescue situations requiring special consideration.  Explain anchor and rigging systems.  Describe basic hand signals used during confined space rescue operations.  Described basic rescue safety rules.

4 Emergency Rescue The Change in Perspective  First priority is to keep all rescuers alive  Do not substitute emotion for intellect  Do not take shortcuts  The person in charge may choose to isolate themselves  Preplanning and training

5 Confined Space Rescue  Confined space emergencies are one of the leading causes of multiple deaths in the workplace  60 percent of victims are would-be rescuers.  Regulation mandates an employer ensures the availability of rescue services prior to space entry.  The rescue team may be from within the plant or from an outside agency.

6 Confined Space Rescue  Rescue team is trained to perform the assigned rescue functions and has received the training required for authorized entrants.  Rescue teams should practice making permit space rescues at least once every 12 months by means of simulated rescue operations.

7 Confined Space Rescue  Employer shall have access to all permit spaces so the rescue service can develop rescue plans and practice operations.  The employer shall also evaluate the response capabilities and training of the off-site response team. (Appendix F to 1910.146)

8 Three Types of Rescue  Self-rescue  Non-entry rescue - external  Entry rescue - internal

9 Self-Rescue Entrant is capable of recognizing a hazard and is able to exit from the space with no assistance.

10 Non-Entry Rescue - external  Rescue performed from outside the space.  Prior to entry, retrieval systems and body harnesses should be in place.

11 Entry Rescue - internal Entry rescue is clearly the form of rescue that presents the greatest risk Entry rescues should be avoided whenever possible Entry rescue requires a considerable amount of equipment

12 Specific Rescue Problems  Vertical entry into tanks and vessels  Dikes or vertical walls  Manholes

13 Anchor and Rigging Systems “Anchor” means to secure ropes and equipment of the rescue system to something that is solid and will not fail under the stress of loading. “Rigging” is the system of rescue ropes and hardware attached to the anchor system.

14 Anchor Rigging  A tensionless tie-off utilizes the friction generated by coils of rope wrapped around the anchor as a means of anchoring a rope.  A 4:1 tensionless anchor requires a minimum of three (3) wraps of rope around an anchor that is at least four (4) times the diameter of the rope.

15 Anchor Rigging  All other rigging must have a backup rig.  If an anchor point has sharp edges, rigging should be padded.

16 Rigging Cautions  Do not run nylon over nylon rigging.  Pad sharp edges as any bend under 4:1 weakens the rope  Avoid hard linking, that is, three (3) or more carabineers linked together.  Double check by sight and touch.  Keep it simple.  A pulley in rigging systems should always be backed up.  Angles greater than 120° cause extra load on anchors.

17 Belaying, Lowering, and Raising Systems  Purpose is to arrest the fall of the load should failure occur in the working line.  Working line and belay line should be established at the same time.  Weight of load determines relationship between working line, belay and anchor.

18 Working Line - Lowering  Performed when rescuers are sent to retrieve a victim  Must be done in a deliberate and controlled manner  Figure – 8 or Rescue – 8 system  Rappel rack  Tandem Prusik belay

19 Raising Systems  Both rescuers and victims must be raised  Winch devices  Rope rescue raising systems  Mechanical advantage system used to reduce the workload on topside rescuers

20 Mechanical Advantage Systems  Simple Series of ropes and pulleys that begin at the anchor or the load and terminates in the hands of those doing the hauling.  Compound Simple mechanical advantage system pulling on a simple mechanical advantage system.
