Introduction
• Rope is one of the most important and routinely used tools in the fire service.
• Firefighters need to know about what ropes are used, knot tying, rope inspection, and storage of ropes.
CHAPTER
15Rope Materials and Their
Characteristics 1 of 2
• Rope characteristics will determine specific applications.
• NFPA 1983 standard for ropes used in the fire service.• Natural materials
• Manila.• Sisal.• Cotton.
CHAPTER
15Rope Materials and Their
Characteristics 2 of 2
• Synthetic materials:• Nylon.• Polypropylene.• Polyethylene.• Polyester.
CHAPTER
15Construction Methods and Their
Characteristics
• Rope categories:• Dynamic.• Static.
• Rope construction:• Laid (twisted).• Braided.• Braid-on-braid.• Kernmantle.
CHAPTER
15
Life Safety Rope
• Ropes, harnesses, and hardware must comply with NFPA 1983.
• NFPA 1983 categorizes ropes and sets strength requirements.
CHAPTER
15
Knots
• Half hitch.• Overhand (safety).• Clove hitch in the open.• Clove hitch around an
object.• Becket bend.• Double becket bend.
• Bowline.• Figure eight.• Follow-through figure
eight.• Figure eight on a bight.• Rescue.• Water.
CHAPTER
15
Inspection• Ropes must be inspected and properly maintained.• All life safety rope inspections should be logged.• Ropes must be individually identified.• Damaged rope should be removed immediately.• Training ropes should be inspected after every use.
CHAPTER
15
Maintenance
• Ropes must be properly maintained.• Follow manufacturer’s recommendations.• Natural fibers limited to brushing off.• Synthetic materials can be washed.• Ropes must be dried prior to use.• Ropes can be stored in coils or rope bags.
CHAPTER
15
Rigging for Hoisting
• One of the primary uses of rope is for hoisting.• Clove hitch, figure eight, and bowline are most often
used for hoisting.• Tag line may also be used.
