What are the different types of lanyards?
Types of lanyards include self-retracting (eliminates excess slack in the lanyard), shock absorbing (slows and eventually stops decent and absorbs the forces), synthetic rope (absorbs some force by stretching), and synthetic webbing (strong but not flexible; absorbs little force).
What are the parts of a harness?
Harnesses include shoulder straps and leg straps, a sub-pelvic assembly, adjustable buckles or fasteners, and one or more D-rings to connect to a lanyard. The dorsal D-ring (between the worker's shoulder blades) is used with a fall arrest system.

This type of fall protection allows a worker to have both of their hands free to work while they remain connected to the work area. It should be noted that this system is not the same as fall arrest, but instead this system is a form of fall restraint.
Travel Restraint
- If workers need to access an area that is near a fall hazard, a safety manager may decide to use a travel restraint system. A harness designed for travel restraint functions will usually have a D-ring in the center of the back at waist-level.
