ATV's typically weigh about 660lbs (300kgs) and the installation of the Quadbar can reduce the risk of injury to the rider if the ATV were to land on the rider in the event of a rollover or side roll. The installation of the Quadbar can reduce this risk by creating a space between the ATV and the ground. "Research has identified injury caused by the pinning of the rider to be of particular concern. (ref: Risk and preventive factors for fatalities in All-terrain Vehicle Accidents in New Zealand, 2009. Boaz Shulruf, Andrew Balemi)
Pinning injuries included:
-Death from asphyxiation - cutting of air supply.
-Death from mechanical asphyxiation - inability to breathe due to forces (weight) on the body – can vary from minutes to hours.
-Death caused by Crush Syndrome - toxins entering the blood stream when the "crush" cause is removed and circulation is restored.
-Death from drowning – often in shallow water, whilst being pinned.
-Death from heart failure – there have been a number of cases of roll over and pinning where the cause of death has been identified as heart failure (conjecture whether heart failure pre or post rollover)
-Loss or reduced capacity of limb(s) – due to lack of circulation.
