3 Identify the appropriate size, strength, type and length of rope to accomplish a fire fighting or rescue task requiring the use of rope: (4-10.1) A Requirements for rope: a) Life safety rope: i) Size: (1) One person- circumference between 1-1/8 and 1-1/2 inches. (2) Two persons- circumference between 1-1/2 and 2-1/4 inches. ii) Breaking strength: (1) One person lbs. (2) Two persons lbs. iii) Maximum work load: (1) Divide breaking strength by a factor of not less than 15. iv) Person classification: (1) Divide maximum working load by a factor of not less than 300.

4 Identify the appropriate size, strength, type and length of rope to accomplish a fire fighting or rescue task requiring the use of rope: (4-10.1) Question: Is manila rope a good type of rope for water rescue? Know Basics on ropes for water rescue and regular rescues. Question: Cotton Rope: Cotton’s tensile strength is slightly less than that of sisal and considerably less than that of manila. Water Rescue: Polypropylene!

5 Identify the appropriate size, strength, type and length of rope to accomplish a fire fighting or rescue task requiring the use of rope: (4-10.1) Question: Static kernmantle rope is most commonly used as rescue rope. T/F Question: Life safety rope is used to support rescuers and/or victims. Because these situations demand a high degree of safety. NFPA 1983!

10 Identify the appropriate size, strength, type and length of rope to accomplish a fire fighting or rescue task requiring the use of rope: (4-10.1) A Uses of knots: a) Bowline: i) Use- to form a loop that will not constrict using a natural fiber rope. ii) Examples: (1) Hoisting a rope. (2) Hoisting a smoke ejector. (3) Cannot be used in life safety situations.

15 Identify the appropriate size, strength, type and length of rope to accomplish a fire fighting or rescue task requiring the use of rope: (4-10.1) a) Clove Hitch: i) Use- to attach a rope to an object and will stand a pull from either direction. ii) Examples: (1) Hoisting an axe (along with half hitches). (2) Hoisting a pike pole (along with half hitches). (3) Hoisting a section of hose (along with half hitches).

22 Identify the appropriate size, strength, type and length of rope to accomplish a fire fighting or rescue task requiring the use of rope: (4-10.1) a) Half hitches: i) Use- to stabilize tall objects that are being hoisted. ii) Examples: (1) Hoisting an axe (along a with clove hitch). (2) Hoisting a pike pole (along a with clove hitch). (3) Hoisting a section of hose (along with a clove hitch).

23 Identify the appropriate size, strength, type and length of rope to accomplish a fire fighting or rescue task requiring the use of rope: (4-10.1) a) Double figure of eight: i) Use- connecting two ropes of equal diameter together. ii) Example: to rope off an area.

28 b) Figure of eight on a bight: i) Use- same as the bowline for synthetic rope and also as an anchoring attachment or harness tie- in. ii) Figure 8s are tighter and stronger than the bowline. iii) They are also not as apt to damage the synthetic rope as the bowline will. iv) Examples: (1) Hoisting a ladder. (2) Hoisting a smoke ejector.

32 Identify the appropriate size, strength, type and length of rope to accomplish a fire fighting or rescue task requiring the use of rope: ( ) a) Becket or sheet bend: i) Use- to attach two ropes of unequal diameter or a rope and chain together. ii) Examples: (1) Tag line. (2) Attachment of a rope to a chain. b) Overhand safety: i) Use- to add a measure of safety to any knot. ii) Examples- used with every knot already mentioned.

37 Overhand Safety Knot As an added measure of safety, use an overhand safety knot whenever tying any type of knot.

38 Question: Use a clove hitch around the head of the axe and at least on half hitch around the handle

39 A half hitch should be tied through the bale of a charged hoseline, so that it will hold the bale in the closed position as the hoseline is hoisted
