Fire escape rope
A life safety rope that is no larger than 5/8 in. (16 mm) and no smaller than 7/16 in. (11 mm), with a minimum breaking strength of 8992 lbf (40 kN).
General use life safety rope
Rope used on extension ladders for the purpose of raising a fly section(s). (NFPA 1931)
Halyard
A knot that attaches to or wraps around an object so that when the object is removed, the knot will fall apart. (NFPA 1670)

Rope record

Round turn

Safety knot
An instantaneous load that places a rope under extreme tension, such as when a falling load is suddenly stopped as the rope becomes taut.
Shock load
The part of a rope between the working end and the running end.
Standing part
A rope generally made out of synthetic material that stretches very little under load.
Static rope
A separate rope that ground personnel can use to guide an object that is being hoisted or lowered.
Tag line
A life safety rope with a diameter that is 3/8 in. (9.5 mm) or greater but is less than 1/2 in. (12.5 mm), with a minimum breaking strength of 4496 lbf (20kN). Used by highly trained rescue teams that deploy to technical environments such as mountainous and/or wilderness terrain.
