1

What rope is designed exclusively for rescue and other emergency operations?

life safety rope

2

What is life safety rope used for?

to raise, lower, and support people at an incident or during training

3

What is NFPA 1983?

NFPA 1983, Standard on Life Safety Rope and Equipment for Emergency Services

4

What rope is designed for any use except rescue?

utility rope

5

What is utility rope used for?

to hoist equipment, secure unstable objects, or cordon off an area

6

What is a single use rope intended for emergency self-rescue situations? This rope is designed to carry the weight of only one person and must be destroyed after its use

escape rope

7

What is a method of manufacturing rope without any knots or splices? A continuous strand of fiber runs the entire length of the rope's core

block creel construction

8

What is a dynamic, sudden load placed on a rope? (typically during a fall)

impact load

9

What must be kept for every life safety rope?

rope log

10

What rope loses its strength when it gets wet and rots rapidly?

natural fiber rope

11

What rope is made from continuous, synthetic fibers running the entire length of the rope?

synthetic fiber rope

12

What are synthetic fiber ropes resistant to?

water, mildew, mold, rotting, shrinkage, and UV light

13

What are advantages of synthetic fiber rope?

longer life span than natural fiber rope, strong yet lightweight, easy to maintain

14

What are disadvantages of synthetic fiber rope?

they will melt when exposed to heat

15

What is a utility rope made of manila, sisal, or cotton? (not accepted for life safety applications)

natural fiber rope

16

What are advantages of natural fiber rope?

resistant to sunlight, does not melt when exposed to heat, and holds a knot firmly

17

What are disadvantages of natural fiber rope?

prone to mildew and mold; deteriorates when exposed to chemicals and burns when in contact with ember or flames

18

What are the most common type of rope construction?

kernmantle, laid, braided, and braid-on-braid

19

What rope is the only one used for life safety?

kernmantle

20

What rope consists of a protective shield (mantle) over the load-bearing core strands (kern)?

kernmantle rope

21

What rope is designed to stretch under load, reducing the shock of impact after a fall?

dynamic rope

22

What rope is designed not to stretch under load?

static rope

23

What are the two types of kernmantle rope?

dynamic (high-stretch) and static (low-stretch)

24

What rope is constructed by twisting several groups of individual strands together?

laid rope

25

What is a disadvantage of laid rope?

susceptible to abrasion and other physical damage

26

What rope is constructed by uniformly intertwining strands of rope together?

braided rope

27

What rope consists of a braided core enclosed in a braided herringbone patterned sheath?

braid-on-braid rope

28

Why is braid-on-braid rope sometimes confused with kern mantle?

bc both are jacketed

29

What is a disadvantage of braid-on-braid rope?

doesn't resist abrasion as well as kernmantle; sheath may slide along the inner core of the rope

30

How do you inspect laid rope?

by untwisting it so that all sides of each strand can be inspectd
