Flashcards in Chapter 8 Deck (56)
What rope is designed exclusively for rescue and other emergency operations?
life safety rope
What is life safety rope used for?
to raise, lower, and support people at an incident or during training
What is NFPA 1983?
NFPA 1983, Standard on Life Safety Rope and Equipment for Emergency Services
What rope is designed for any use except rescue?
What is utility rope used for?
to hoist equipment, secure unstable objects, or cordon off an area
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
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
What is a dynamic, sudden load placed on a rope? (typically during a fall)
What must be kept for every life safety rope?
What rope loses its strength when it gets wet and rots rapidly?
natural fiber rope
What rope is made from continuous, synthetic fibers running the entire length of the rope?
synthetic fiber rope
What are synthetic fiber ropes resistant to?
water, mildew, mold, rotting, shrinkage, and UV light
What are advantages of synthetic fiber rope?
longer life span than natural fiber rope, strong yet lightweight, easy to maintain
What are disadvantages of synthetic fiber rope?
they will melt when exposed to heat
What is a utility rope made of manila, sisal, or cotton? (not accepted for life safety applications)
natural fiber rope
What are advantages of natural fiber rope?
resistant to sunlight, does not melt when exposed to heat, and holds a knot firmly
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
What are the most common type of rope construction?
kernmantle, laid, braided, and braid-on-braid
What rope is the only one used for life safety?
What rope consists of a protective shield (mantle) over the load-bearing core strands (kern)?
What rope is designed to stretch under load, reducing the shock of impact after a fall?
What rope is designed not to stretch under load?
What are the two types of kernmantle rope?
dynamic (high-stretch) and static (low-stretch)
What rope is constructed by twisting several groups of individual strands together?
What is a disadvantage of laid rope?
susceptible to abrasion and other physical damage
What rope is constructed by uniformly intertwining strands of rope together?
What rope consists of a braided core enclosed in a braided herringbone patterned sheath?
Why is braid-on-braid rope sometimes confused with kern mantle?
bc both are jacketed
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
