22

What determines the need for a rope rescue

Any event where a patient or rescuer has a possibility of a fall

23

What unit of force is used to rate strength of equipment used by EFRS

KiloNewton (kN)

24

What is the formula to calculate the KiloNewton?

F=m x a

F= kg x m/s2

25

'P' rated carabiners are rated at

26.67kN

(27kN)

26

'G' rated carabiners are rated at

40kN

27

What is the strongest part of the carabiner?

It's long (or major) axis

28

Why is it necessar to use padding over edges when performing a rope rescue?

The rope must be protected from damage during operation

29

Define natuarl anchors

The most common type of natural anchors are trees, large rocks, and outcroppings that can be wrapped with webbing or ropes.

30

Describe Structural anchors

A place of structural integrity such as major load bearing beams and billars, window washer anchros, window/door frames, roof scuppers etc.

31

Describe Pseudo anchors

These are anchor points that may be used as an anchor, but under certain conditions it may move.

32

What does the acronym IDEAS stand for?

  • Integrity
  • Direction of force
  • Equalization and no Extension
  • Angles
  • System of Anchors

33

What are the three tests of a rescue system?

  • White board analysis
    • Does the system function as intended?
    • How do you know for sure?
  • Critical points examination
    • are all points backed up by another system
    • could one point fail and cause a serious accident
  • Whistle test
    • if every rescuer let go of their system, would the system still protect the patient and the rescuer?

34

What does SSSF mean?

Static System Safety Factor

35

Name the equipment used to construct a proper anchor?

  • Webbing
  • Rope
  • Industrial slings
  • Carabiners
  • Rigging plate
  • Swivel

36

What is the SSSF followed by EFRS?

10:1

37

Who on the team can call for a STOP?

Anyone

  • Everyone has the responsibility to call stop if they recognize a hazard. The team leader must inquire the reason for the stop.

38

Explain the I in IDEAS

Integrity

  • Integrity of anchor point
  • How is it rooted to ground/building
  • Does it have sufficient mass to suppor the force that may be applied to it?

39

Explain the D in IDEAS

Direction of force

  • Direction of the force of the load upon the anchor
  • anchor should be in line with the force being applied, or any anticipated direction of force

40

Define the A in IDEAS

Angles

  • Examine for Critical angles
    • These may cause failure in the system

41

Explain the E in IDEAS

Equalization and No Extension

  • Anchor legs should have equal tension
    • This shares the load
  • No Extension in the system
    • Extension is movement of the focal point.
    • Should one anchor leg fail there should not be any extension of the anchor legs causing high impact forces to be placed on teh remaining anchor point

42

What are the degrees of force on each leg of an anchor with a critical angle of:

  • 0
  • 30
  • 90
  • 120
  • 150
  • 180

 

0 = 50%

30 = 52%

90 = 70%

120 = 100%

150 = 200%

180 = Infinite

43

Explain the S in IDEAS

System of Anchors

  • What type of anchor system is required
    • What are the advantages/disadvantages of the system
