According to the present invention there is provided a hand guard for drilling rig hand tongs which includes a resilient body having a first end and a second end. Means is provided for securing the first end of the body along a first edge of a jaw of the drilling rig hand tongs adjacent to a hand gripping bar. Means is provided for securing the second end of the body along a second edge of the jaw adjacent to the hand gripping bar. The body extends above and shields the hand gripping bar.
Two embodiments of hand guard will hereinafter be further described. A preferred embodiment clamps onto supporting bars supporting the hand gripping bar of existing drilling rig hand tongs to provide protection against crushed hands and fingers. An alternative embodiment clamps onto an edge of a jaw of the drilling rig hand tongs adjacent to the hand gripping bar.
