Considering the wide variety of lines that'd be good for life support, maybe they should just mark the one's that are NOT good for life support.

Right, but you'd have to be able to trace the line to who made it and what "model" it is first to get that information; isn't this where unique traceability would come into play?
I mean, we can pick up a white and orange line with a blue core, look at the tracer inside and see it's NE Saftey-Blue Hi-V; then look up it's specs.
Same with say, ArborPlex- you can spot it a mile away as being exactly that brand/model.
I just wondered if it was a requirement because the ropes are INTENDED to human support, that's all.
Like saddles always have the manufacturer and model and DOM on a label that's darn hard to remove.

Okay, now I see where you're going with this.
From what I've seen, rope makers try to make their lines as unique as possble. Yes, they all have an all while double braid polyester but similarities don't extend much further. It takes a familiarity with all the lines available to be able to figure it out.
On many an occasion, I've found rope in marine stores that had the manufacturers name on the side, but no clue as to what the line was. I would jot down all the rope info (construction, color of cover and core. Tracer strand colors, single/double/triple ended strands, diameter, number of strands, etc) and call the manufacturers directly and ask them. It's like detective work. I have many times considered creating a database that has ALL the rope ID's throughout history. (I've shyed away from this because it seems that the energy required to do it would not get used by enough people to make it worthwhile...though it would be an awesome reference!)
I onced worked for a guy in WI that had a spool of rope in one of his store rooms. He asked if I could splice any rope. He says, "I got some rope that I'll give you 150.00 if you can splice an eye on some of this rope I got in the back." I say, bring it on!
He takes me back there and before me stood a 5 foot tall spool of 300' of a 3" nylon three strand! Yikes! I told him I'd like to talk with the manufacturer before I splice it. I cut off 6" went home and tried to figure out who made it. It took a while, but I eventually found a tiny labeled tracer (like the one they put in 20 dollar bills). It had the manufacturer, year it was made, the type of nylon...everything!!! I called them right up (I don't remember who it was) and found out what I needed to know, made a big fid for it, and spliced it the next day (It was raining, so I had some time!)
How nice would it be if every manufacturer did that?
So, yes, I totally agree that manufacturers should make their lines identifiable. Also, people should buy lines that area identifiable. I always avoid buying all white ropes (these are the most common). Yale does a good job in some of their catalogs of describing the lines.
"Double Esterlon is identified by two adjacent green strands braided into the cover structure. The date of manufacture is denoted by colored yarn between the core and the sleeve."
That came from their Industrial cordage catalog. That info could be very valuable to the right person.
Ok. I'll stop there.

seanlarkin, did you call me a rope nut?

unidentified ropes/straps
Gabbster, just remember that your life is in the balance when you use an unknown. What is your life worth? You do the right thing to ask but until you know who made it and what it is rated for don't use it where a life could be lost if it fails.

Very true, I had never planned to use it in a situation that could be life threatening. Light rigging, in just small branches maybe. I just wanted to take the oppurtunity to learn about rope makes and strengths. I work for municipal government, I will just buy appropriate materials. We have a well developed safety program here and we are reviewed on it.
Thanks for all the info guys, I learned a lot.
Wish me luck, I take the CA test this Wed.
