Ropes And Knots Flashcards
What is a line?
A line is a piece of rope cut to a specific length.
What sort of ropes does ACTFR use and why?
Synthetic Fibre Ropes
Absorbs shock loads, little swelling in water, stores without deteriorating, good weight to strength ratio.
Name some parts of a line.
Coil, Standing Part, Round Turn, Turn, Underhand Loop, Overhand Loop, Bight, Running End.
What construction are ACTFR lines? And What does each part do?
Kernmantle Construction
Kern: core, takes load.
Mantle: Sheath, protects Kern.
What are three lines used by ACTFR and their specs/uses
GP Line: 13mm diameter, 15m long, 500kgs WL, Hauling.
Pocket Line: 6mm Diameter, 3-4 meters long, 100Kgs WL, Tying off ladder.
Rescue Line: 13mm Diameter, 50/100/200 meters long, 500kgs WL, used for rescue situations.
(All Kern-mantle)

Name two types of Line Deterioration and their causes.
Mechanical: dragging, kinking causing abrasions cuts. Overloading.
Chemical: mildew, heat, sun damage
What care is taken with Lines?
Stored away from industrial processes, not in sunlight. Washed throughly, stored in bags.
Name two ways of inspecting a line and what they involve.
Feeling for: cuts, lumps abnormalities and changes in diameter.
Look for: abrasion, exposed core, discolouration.
How would you wash a line?
In fresh cold clean water. Mild soap. Agitate in water. Hang to dry, not in sun. Don’t use dryer.
What are the four requirements of a knot?
Serve the purpose
Easy to tie
Easy to untie
Doesn’t damage the line
Where and how should lines be stored?
In their protective bag and on relevant appliance or appropriate area in station.
When should lines be inspected?
Monday check, before during and after use.
When should you report and replace a line?
Excessive sheath wear, subject to serve shock load, used above safe working load, line has been cut and line has become hard and brittle.
What are the 9 knots used by ACTFR?
Half Hitch
Overhand
Clove Hitch
Rolling Hitch
Bowline
