Body harnesses are the instantly recognizable body-cradling straps that provide the first line of defense. They support the user while they work and keep them suspended in the event of a fall. Many varieties are available, typically featuring D-rings on the back and hips to attach lifelines, lanyard, and tools, as well as an impact indicator that shows at a glance if the harness has been worn in a fall (at which point it is discarded).
