Basic Firefighting Knots : Firefighting Knots: Prusik

[myurechko]

that is about the only way to mess up a prussik knot.

Next time tie it with out the knot in your loop being in the middle of the prusik knot. Also, you use this as a way to secure to another rope, to ascend, descend or to belay. Not to tie off onto a crow bar. that would be a girth hitch. I like the smoke at the end though.

Nice try though. There are a number of good books you should check before coming across as someone who knows what he is talking about.

it is the right know he was just showing how it is done and tell you where it can use it not where it should use the knot.next time you try to tell some 1 there wrong watch the video

@myurechko --- I really appreciate these guys taking the time to demonstrate all these knots, and I have learned a few new ones by watching this channel, but myerechko is right. Your prussik will not work with your double over-hand bend smack in the middle! May work for tying off a halogen bar but not as a brake on a main line while hauling a patient and three rescuers.

[jasonhodgen]

(Not sarcastic) Why is it necessary for the bight to go around the halogen more than just once? Is that just so that you can balance it better?

[trekhardfilms]

The more times your prusik knot goes around,the tighter and more secure it will be.

@jasonhodgen: 3 wraps is the best for holding. I've seen a test where 4 loops were used and the hitch only moved about 1/2 inch in a drop. The three loop prusik slipped about 12 inches. BUT the load on the rope with the 4 loop was about 4X that of the 3 loop. As the three loop slipped a bit, it absorbed the pressure. Something like a dynamic rope does during a climbing fall. PS if I ever to be rescued, send me a climber, not this fire captain. What a nasty looking prusik.
