NFPA 1001 Life Safety & Utility Knot Standards
Knots in the fire service are divided into life safety applications (supporting human loads) and utility hoisting (raising axes, halligans, charged lines, and ladders to upper windows and roofs).
Core Fire Service Knots
- Figure-8 on a Bight: Primary life safety tie-in knot; retains 75โ80% of rope tensile strength and remains easy to untie after loading.
- Bowline: Forms a secure, non-slip loop at the end of a utility line; excellent for securing equipment or hoisting uncharged hose.
- Clove Hitch: Two interlocking half hitches; optimal for anchoring around round objects like pike poles, axes, or timber posts.
- Becket (Sheet) Bend: Connects two ropes of unequal diameter together securely.
- Water Knot: The only approved knot for joining flat tubular nylon webbing loops.
