There is a release mechanism lever which is integrated into the ratchet to enable the ratchet to be over ridden and released. This must be secured in the correct location to ensure the ratchet mechanism is able to be work effectively. It is the responsibility of the wearer to ensure the harness is secured and not damaged or altered in any way. Harnesses should be inspected before use and should be replaced regularly. Harnesses should be replaced after any collision or in any event that may affect the integrity of the harness.
