Large Area Search Line marking?
We are upgrading to a new Search Line kit with the Sterling Searchlite rope. It will be 220' long. I know one of the most popular ways to mark the rope is using knots and rings at 20' increments. We can deal with the knots, since they add no weight to the line and they are not a major hassle to smooth feeding of rope out of the bag. We are trying to avoid using rings because of the weight and rope feeding issues. I tried to find someone making aluminum rings but had no luck.
Does anybody have any tips or suggestions in regards to marking a rope for both distance and direction? One option that was suggested is to put knots close together for the distance marks and then have a seperate knot 10" away as the directional knot. It has to be something large enough to allow an easy feel with gloves.
Paint and tape will not work obviously.
Our Large Area Search Line
We are setting-up our Large Area Search Line to have clips/carabiners on both ends to secure the rope back onto itself.
At intervals of 50' we are making (1) knot for each 50' of line that has been deployed (we chose 50' because that is how long each section of our Fire Attack hoses is). To indicate which direction you are going it's fairly simple; the rings lead into the building and the knots lead out of the building.
From the beginning of the Kevlar Rope it goes like this: Clip/carabiner, rope, 50' in (1) knot, 6" after that is a knot with the 2" ring tied into it, rope, 50' (2) knots, 6" after that a knot with another 2" ring, rope, 50' (3) knots and then the end of the rope on the 200' bags. The 300' bags have (1) additional ring and the appropriate number of knots for the distance.
We have several "Wide Rises" that both bags work well for. If you're going to use them for Residential Occupancies I would recommend the same length as your Attack Lines.
