13 Artificial High- Points and their effect on efficiency! 13

14 What are artificial High Points 14

15 Artificial High Directionals, or AHD s, allow a qualified rescue team to redirect the path of their load lines around and over obstacles. 15

16 They can include: Tripods Davit arms Monopoles Bi Pods Ladders Aerial Ladders Just about anything strong enough to support a load! 16

17 Why do we use Artificial High Points? 17

18 Although the uses for a versatile AHP are limitless, the most frequent is to reduce edge trauma in raising and lowering systems 18

19 As Firefighters.When do we use them? 19

20 Mostly during training evolutions & real rescue situations. 20

21 Where do we use them? 21

22 Off a Highrise! 22

23 Wilderness 23

24 Vehicle Incident 24

25 Confined Space 25

26 Water 26

27 Industrial 27

28 Animal 28

29 Three Questions about Artificial Highpoints that Firefighters should always ask themselves! 29

30 Do they make us faster? 30

31 Do they make us safer? 31

32 Do they make us more efficient as first responders? 32

33 Lets Start with Tripods! 33

34 Do Tripods make us faster? 34

35 Yes! 35

36 Yes and No! 36

37 A traditional industrial Tripod is not glamorous! Yet it is quick and easy to set up! 37

38 They are: -Quick to deploy -Relatively easy to store -Have a Low training curve -Inexpensive -Are relatively stable if the resultant stays within the base. 38

39 Resultant 39

40 However: -They can be too low! -Have a poor rated capacity -Generally not very versatile! 40

41 So we embrace Technology! 41

42 So we embrace Technology! -TerraDaptor -Air Shore/Hurst -Arachnipod -Arizona Vortex -Paratech 42

43 We gain: -Strength -Durability -Versatility 43

44 But we also gain: Complexity 44

45 With it comes a larger learning curve. And Slower deployment!!!!! 45

46 Do Tripods make us safer? 46

47 Again.. Yes & No! 47

48 Protects the ropes & equipment Creates easier access 48

49 Tripods are only stable if the resultant remains within the footprint. : 49

50 Often the biggest challenge is to visualise the resultant for the entire operation. It may be well defined for 90% of the task but the other 10% may include movement outside of the base. 50

51 Crews that use high directional frequently understand the effects of resultants. Those that don t.make mistakes! 51

52 Do Tripods make us more efficient as first responders? 52

53 Depends!!! 53

54 Does your event require a sense of urgency? 54

55 A simple system can be set up in less than a minute 55

56 Complex tripod systems use up valuable time. 56

57 Ladders & Aerials as High Directionals 57

58 Are they safe to use as a High directional? 58

59 The ladder only becomes an issue when it is not used vertically. 59

60 The flatter the angle the higher the resultant force on the horizontal plane of the 60 ladder..

61 When rigging the haul system or the Mechanical Advantage the resultant force is always in line with the beam of the ladder. 61

62 Back tie all four corners Directional anchors incorporate both rails 62

63 63

64 64

65 65

66 Aerials as a high point 66

67 Can rope rescue damage an Aerial ladder? 67

68 Yes! 68

69 Can we safely use an Aerial Ladder for rope rescue? 69

70 Yes 70

71 Fulcrum point An aerial is essentially a Class 1 Lever 71

72 72

73 73 OK

74 74 Better

75 75 Best

76 Tips to reduce stress on the fulcrum point of a ladder 76

77 Get as close as possible to your subject This may include backing in to get your turntable closer 77

78 Increase the angle of the ladder Keep as much of the fly in the bed as possible 78

79 Balance your anchor points from both rails Limit your load to a single person 79
