Fall arrest systems have been shown to save lives in certain situations. For example, if someone falls from a height and would have otherwise landed on their head, a fall arrest system can prevent serious injury or death.
So how do they work? A fall arrest system is a form of individual fall protection that prevents the user from hitting the ground, structure, or any other obstruction during a free fall while also reducing the body’s impact force when it is placed under arrest.
Fall Arrest vs. Fall Restraint – It’s Important to Know the Difference
At times, people will use the terms ‘fall arrest’ and ‘fall restraint’ interchangeably. Although they are closely related, there is a difference between these two forms of fall protection.
While a fall arrest system prevents a person from falling any distance – whether it’s two inches or 100 feet – a fall restraint system keeps a person from reaching a certain point on a walking/working surface – typically less than six feet above the walking/working surface. Both systems work by applying force to arrest or slow down your motion as you pass through them during free-falling but each one does so using different methods.
There are three main types of fall arrest systems:
Body belts and straps
These are designed to fit around the waist and upper body, with a strap between the legs. They are not as effective as other options and can cause discomfort.
Harnesses
These distribute the fall force over the thighs, hips, and pelvis. They are more comfortable than belts and straps, but can still cause some discomfort.
Full-body harnesses
These distribute the fall force over the entire body, making them the most effective type of fall arrest system. They are also more comfortable than other options. Fall arrest systems save lives by preventing people from hitting the ground in a fall. This can reduce or prevent injuries such as fractures, head injuries, and internal injuries. While any type of fall arrest system is better than no system, full-body harnesses are most effective.
What sectors use these systems?
They are most commonly found on construction sites, shipyards, and at height maintenance jobs.
What are the advantages of full-body harnesses?
These systems can greatly reduce injuries by preventing falls in the first place. They also distribute force over the entire body during a fall. This reduces pain on landing that can come with other systems. Finally, they are comfortable to wear for long periods of time and do not restrict movement like some other options (e.g., belts and straps).
What types of work activities require these systems?
Workers engaged in any type of work activity that requires frequent or occasional high-rise access benefit from using full-body harnesses. They will be more comfortable and have a greater range of motion, allowing them to complete their work tasks more safely. Some common examples of activities that require the use of a full-body harness include construction, window washing, bridge painting, and tower inspections. Anytime there is a potential for a fall from height, it is best to use a harness for safety. Even if you do not think you will be in danger of falling, using a harness can still help prevent injuries in the event of an unexpected fall.
