A safety gadget is a system of 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 gadget allows the user to attach themselves to a stationary object, therefore ensuring they will not hit the ground in the event of a fall. Falling from a height is one of the most common causes of personal injury in the workplace, so it is very important to make sure you are properly equipped when working up high.
