\nKnowing how a system works\/affect to the human body is as important as how to operate it.\nWhether you are an iron worker who has slipped off an I-beam or a rescuer whose fall is being arrested by a belay line, you will feel the arresting forces.

\n\u2022\tHarness Fit. Anyone who has actually fallen (or hung) in a full-body harness is keenly aware of one fact: The Fit Matters. If a harness is poorly adjusted – if there is slack in the straps or the leg or chest straps aren’t positioned properly – the transmission of the arrest forces will not be as clean and elegant as the harness designers intended. They designed the harness to transmit most of the forces to your pelvis which is the largest and strongest bone in your body. But if the straps slide up or down as you fall, other parts of the body may be the ones absorbing the impact. Chest straps positioned below the breasts (whether male or female), or leg straps that slide up and apply force to the wearer’s crotch can cause serious injuries.
\n\u2022\tContents of Your Pockets. Even a well-adjusted harness will slide to some degree. The question that the wearer needs to answer is: What will happen if the straps jam the contents of my pockets upwards? That ball point pen in your chest pocket or the Leatherman in your front pants pocket can ruin your day if they end up imbedded in your muscles. And in a fall there will a lot of force available to imbed those items. Cargos pockets on the sides of work pants shouldn’t be an issue, but other pockets need to be emptied. The fact that some of the newer harnesses include small pouches for these types of items is a step in the right direction.
