NOTE Historically, rope access technicians used a sit harness coupled with a chest strap or chest harness, which served a dual purpose of holding the chest ascender in its correct orientation and in assisting the user to be supported in a more upright position than typically a sit harness would do alone. Although this combination is still common, an alternative is to use a specially designed full body harness that combines the necessary sit harness support function with the facilities described above and which also provides a high attachment point for the backup device (typically via a short device lanyard). In the unlikely event of a fall, the wearer is always maintained in an upright position and, arguably, the potential for hyperextension of the head (whiplash) is reduced. These harnesses usually conform to appropriate fall arrest harness standards and thus meet legislative and other authority requirements or recommendations for harnesses to be used for work where a fall could occur.
