FF 1 Test Review (Statements)

• Fire service rope is either constructed of natural or synthetic materials.
• Natural fiber rope is only acceptable for utility applications.
• Polyethylene rope is characterized by a slick and oily feel and is manufactured in bright colors.
• Manila rope increases in tensile strength by 15% when wet.
• The advantage of cotton rope is that it is inexpensive.
• Nylon rope has the best shock load ability.
• Polypropylene rope is popular with water rescue incidents because of its ability to float.
• Polyester rope resists rot and sunlight damage.
• Aramid fiber displays resistance for knot tying and has poor shock-absorbing capabilities.
• Static rope is preferred for rescue work because of its low-stretch factor.
• Dynamic rope is not practical for hauling applications.
• Laid rope is usually constructed of 3 strands.
• Braid-on-Braid rope contains 1/2 of its strength in its sheath and 1/2 in its core.
• Braided rope resists twisting which is common in laid ropes.
• Laid rope is also called twisted construction.
• Braided rope has 3/4 of its strength in its core and 1/4 in its sheath.
• Laid rope is easiest to inspect, however it is most susceptible to physical damage.
• Static Kernmantle is most commonly used as rescue rope.
• Natural fiber ropes should be cleaned by wiping or gently brushing.
• Rope can be dried by air drying, drying in a hose tower, drying on hose racks, or drying in a hose dryer.
• When using a clothes washer to clean rope, cold water should be used.
• Front-loading clothes machines should be used when cleaning rope.
• Mild soap should be used when washing rope.
• The best way to clean synthetic rope is a clothes washing machine.
• Rope logbooks should be kept in a waterproof envelope in a pocket on the rope's bag.
• Utility rope is used to hoist tools and equipment, not for rescue line.
• Rappelling requires the use of life safety rope.
• The becket or sheet bend knot can be used to join ropes of unequal diameter or to join rope to chain.
• A figure-eight follow through is commonly used to join ropes of equal diameter.
• A figure-eight on a bight is commonly used to secure a loop in the middle of a rope.
• A bowline can be used when a non-constricting loop is needed around an object.
• The overhand knot is the most commonly used safety backup knot.
• A clove hitch is most commonly used for attaching ropes to objects and hoisting operations.
• During hoisting operations, the hand-over-hand method should be used to maintain control.
• H. Spectra® rope fiber is most resistant to abrasion.
• Another name for Dacron® rope is polyester rope.
• Polyester rope is most resistant to the sun's ultraviolet rays.
• Nylon rope is the most dynamic (high-stretch).
• H. Spectra® and polyethylene fibers are most susceptible to heat deterioration.
