What type of materials are life safety ropes made out of?
Synthetic ONLY: they must be made of continuous filament virgin fiber and woven of block creel construction.
(high stretch) used long falls, rock climbing, designed to stretch without breaking. Disadvantages when raising or lowering heavy loads due to tis elasticity.
(low stretch) rope rescue incidents designed for low stretch without breaking, used for repelling, hauling, low to no fall
- light use life safety rope - support weigh of one person

What is a loop?
