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.

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.

Life Safety Rope
• Ropes, harnesses, and hardware must comply with NFPA 1983.
• NFPA 1983 categorizes ropes and sets strength requirements.

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

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.

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.
CHAPTER

WRAP-UP
• This is only basic rope information.• Knot tying and rope use should be practiced regularly.• Proper maintenance and inspection is essential.
