A safety harness is a form of protective equipment designed to safeguard the user from injury or death from falling. The core item of a fall arrest system, the harness is usually fabricated from rope, braided wire cable, or synthetic webbing. It is attached securely to a stationary object directly by a locking device or indirectly via a rope, cable, or webbing and one or more locking devices. Some safety harnesses are used in combination with a shock-absorbing lanyard, which is used to regulate deceleration and thereby prevent a serious G-force injury when the end of the rope is reached.
An unrelated use with a materially different arresting mechanism is bungee jumping. Though they share certain similar attributes, a safety harness is not to be confused with a climbing harness used for mountaineering, rock climbing, and climbing gyms. Specialized harnesses for animal rescue or transfer, as from a dock to a vessel, are also made.
Safety harnesses have restraints that prevent the wearer from falling from a height. By wearing the belt or harness the risk of injury from a fall is greatly reduced. The harness allows the user to attach themselves to an object that is stationary, ensuring they will not hit the ground in the event of a possible fall. Falling from high areas is one of the most common causes of injuries in the workplace, so it is very important to make sure you are properly equipped when working up high.
Before safety harnesses were required by OSHA (The Occupational Safety and Health Administration), workers wore body belts to connect to fall protection systems. Workers had the belts fastened around the waist, resulting in the entire force being exerted on the abdomen and often causing significant injury.
OSHA implementing this requirement really made sure the amount of casualties decreased from falling, as well as injuries caused from the old belts they used to wear. Safety harnesses are essential while working in high areas to prevent significant injury or death, and OSHA making these a requirement made everyone understand the importance of safety-harnesses

In North America, safety harnesses designed for protection against falls from heights in industrial and construction activities are covered by performance standards issued by the American National Standards Institute (ANSI) in the United States and by CSA Group (formerly known as the Canadian Standards Association) in Canada. Specifically, the standards issued are ANSI Z359.1,[1] and CSA Z259.10.[2][3] These standards are updated approximately every four to five years. The main purpose of the safety standards is to "act as a standard to drive best-in-class harnesses through rigorous design and test requirements. in addition to having requirements for manufacturers to create an ANSI-approved full body harness." The update to Z359.11 includes revisions and new requirements, including A modified, headfirst, dynamic test procedure, New stretch-out requirements for frontal connections, Alternative fall arrest indicator testing and new label requirements, Allowance for harnesses with integrated energy absorbers, and Changes to labeling requirements. It. requires harness label packs to have pictograms showing the approved usage of different connections and diagrams explaining the difference between deployed and non-deployed visual load indicators. These new standards help give the user a level a confidence, while knowing it has gone through rigorous testing to ensure that what you are using is completely safe and effective.

A video on the importance of fall protection in occupational settingsA fall arrest harness is the equipment which safely stops a person already falling.
A window cleaner who can be working up high on buildings need to use harnesses to keep them from falling many stories if they slip. That is the most common safety harness. A theatrical fly crew member will need a harness because they are up above the theater floor and they need to be safe in case they slip as well. Construction workers might need a harness because they could be building on the higher floors and without the harness they could fall to the ground. Crane operators will be at a height that will cause great injury or death if they were to fall off, so they need something to ensure their safety as they are working. A lineman has to climb power lines and they need to be secured in place so they can work on the high voltage lines without moving around. Harnesses are used when sailing to prevent the crew from being thrown overboard in case the seas are rough.

A climbing harness is a device which allows a climber access to the safety of a rope.
Rock climbers use harnesses to belay each other, this is when they use a rope to connect to one another so if the climber falls they can catch them with the rope instead of falling all the way to the ground.

A jackstay harness is a substantial line between two points used to guide or support.
Bungee jumping requires a harness to get the person to bounce back up, without it there would be no way to prevent the jumper from falling straight to the ground. In motorsport harnesses keep the driver secure in the event of a crash, keeping the driver secured in place gives the person more of a chance to leave without injury.

A lifeline harness is a rope connecting the diver to an attendant, usually at the surface.
A professional diver would use a safety harness to keep close to something they are working on underwater, without the harness they could be pulled away from their work by a current.

To be sure that a safety harness is not going to fail when in use there are things the user needs to check before they put their lives in the hands of said equipment. The main problem would most likely be frying from prior usage. Another problem would be from improper storage and that would be cracks in the harness, this would make the harness much less durable and much weaker. Finally the wearer needs to be sure to check the fasteners for damage so that part does not fail independently from the harness itself.

What is a Full Body Harness?
A full body harness is a safety harness that connects the worker to the fall protection system anchored into the structure they&#;re working on. Using a series of straps that fit around the thighs, hips, chest, shoulders, and back, these harnesses arrest falls while minimizing injury to the worker. Full body harnesses are also designed to keep wearers upright after a fall to prevent suspension trauma and facilitate faster rescue.
As you&#;ll see below, however, the harnesses recommended today haven&#;t always been the most common option. It took several decades to develop a full body option that doesn&#;t prolong the danger caused by a workplace fall.
Full Body Harness vs. Body Belt
Initially, fall protection systems relied on a single belt, usually made of leather or canvas and worn around the waist, to prevent falls. Though this did arrest some falls, it wasn&#;t always successful. And when it did work, it often created new dangers, including:
Internal injuries or death from the impact and/or being suspended for too long
Further injury if the worker slipped out of the belt
Asphyxia if the belt shifted under the armpits
Impacts, particularly to the head, if the wearer flipped upside down
In the s and s, workers began using two lanyards for additional safety. Known as a &#;100% tie-off system,&#; the second lanyard offered backup protection if anything happened to the first. It didn&#;t, however, prevent the hazards of using body belts. If you fell &#;correctly,&#; horizontally, you were often fine, but falling in any other position put you at serious risk.
Several safety organizations, including OSHA, tested body belts throughout the late s. In one test performed by the British Standards Institute&#;s National Engineering Lab, the body belt folded the dummy in half, slamming its head against the surface below. In another study by OSHA, engineers determined that an average-sized woman could survive for 2.5 minutes while suspended in a body belt. The average-sized man would only last 32 seconds.
Though some companies used safety harnesses rather than just body belts as early as the s, they didn&#;t become common until OSHA banned body belts as the only form of fall protection in . Inspired by the harnesses used by paratroopers, manufacturers developed harnesses that strapped across the upper and lower body to distribute weight more evenly.
Over the years, we have seen not just an evolution of the harness, but a revolution in comfort. Manufacturers use materials that are lightweight and strong enough to withstand regular use. The straps are arranged to arrest falls with minimal injury and maximum comfort during use. The dorsal D-ring is used universally because of the convenience it offers and the way it helps to distribute weight.
Today, full body harnesses improve safety in two main ways. Along with an optimized design, they are no longer uncomfortable to wear or use. Workers can easily and conveniently use them for specific tasks, encouraging regular use and increasing workplace safety.
