ROPES AND KNOTS L.B.F.D. TRAINING DIVISION
OBJECTIVES • ABILITY TO TIE KNOTS 1-8 ACCORDING TO GRADING CRITERIA. • IDENTIFY THE ROPE WEAKENING CHARACTERISTICS OF KNOTS 1-8. • UNDERSTAND THE CARE, MAINTENANCE, HANDELING AND STORAGE OF ROPE. • IDENTIFY THE TYPES OF ROPE CARRIED ON L.B.F.D. ENGINE CO. • EXPLAIN HOW SPLICES ARE USED IN LADDER HALYARDS.
ROPES USED BY THE L.B.F.D. ARE MADE OF MANILA, COTTON AND NYLON
MANILA ROPE • 3/8” MANILA ROPE IS USED FOR LADDER HALYARDS. • 1/2” & 3/4” 100-200’ LENGTHS ARE USED FOR UTILITY LINES, SHORTER LENGHTS ARE USED FOR SECURING THE HOSE ROLLER.
CARE AND MAINTENANCE • AVOID PULLING OR DRAGGING OVER ROUGH OR SHARP EDGES. • PROTECT ROPE FROM ACIDS SOLVENTS OR HARSH CHEMICALS. • AVOID OVERLOADING AND SHARP BENDS OR KINKS IN ROPE. • THOROUGHLY DRY ROPE AND STORE IN AREA FREE OF MOISTURE.
NYLON ROPETWO AND HALF TIMES STRONGER THAN MANILA LINE OF THE SAME SIZE.
NYLON ROPE • LIFE LINES • HOSE STRAPS • RESCUE WEBBING • FIRE BOATS
ROPE/DROP BAGS • 75’ OF DOUBLE BRAIDED 5/16” NYLON LINE. • USED AS A UTILITY LINE.
LIFE LINESHALF INCH STATIC KERNMANTLE NYLON LINE.150-600 FOOT LENGTHS
KERNMANTLE80/20 MANTLE KERN
STATIC KERNMANTLE LIFE LINE SPECIFICATIONS • MAXIMUM SAFE WORKING STRENGTH 1,000 POUNDS. • MINIMUM TENSILE STRENGTH 9,000 • MAXIMUM AVERAGE STRETCH 1.5% AT 200 POUNDS. • 10% OR MORE STRETCH AFTER LOAD HAS BEEN RELEASED, REMOVEL FROM SERVICE.
STAIC KERNMANTLE LIFE LINE SPECIFICATIONS • MELTING POINT 480 DEGREES. • MAINTAIN PROPERTIES AND STRENGTH TO 350 DEGREES. • ABRASION RESISTANCE IS THREE TIMES THAT OF LAID MANILA ROPE.
STATIC KERNMANTLECARE,MAINTENANCE AND STORAGE • DO NOT STAND, WALK, JUMP ON OR DRAG ROPE. • AVOID GAS, GREASE , OIL AND HARSH CHEMICALS. • AVOID DIRECT SUN CONTACT. • AVOID HEAT FROM FRICTION.
STATIC KERNMANTLECARE, MAINTENANCE AND STORAGE • CLEAN WITH ROOM TEMPERATURE WATER 40 DEGREES, MAY USE MILD DETERGENT OR FABRIC SOFTENER. • INSPECT AND INVENTORY AFTER EACH USE. • STORE LOSE AND DRY, AVOID KINKS AND VIBRATIONS. • ALTERNATE END OF LIFE LINE AFTER USE.
INSPECTION OF KERNMANTLE ROPE • INSPECT AFTER EACH USE • FEEL ROPE FOR FUZZINESS AND CHANGES IN DIAMETER ( HOURGLASS) • LOOK FOR: PUFFS- CORE FIBERS THAT PROTRUDE FROM THE SHEATH. • LOOK FOR: BOOGERS- SEVERLY WORN PLACE POSSIBLY SHOWING CORE STRANDS. • EXAMINE FIBER BUNDLES ( PICS) IF MORE THEN 50% ARE BROKEN , IT IS TIME TO RETIRE THE ROPE.
INSPECTION OF KERNMANTLE ROPE • IF A ROPE HAS TAKEN A HARD FALL OR HAS BEEN USED FOR A NON-STANDARD TYPE USE, SUCH AS TOWING A CAR, IT SHOULD BE RETIRED.
