WAC 296-304-07005   Shackles and hooks.  (1) Shackles.

     (a) Table G-10 in WAC 296-304-07011 shall be used to determine the safe working loads of various sizes of shackles, except that higher safe working loads are permissible when recommended by the manufacturer for specific, identifiable products: Provided, That a safety factor of not less than five is maintained.

     (2) Hooks.

     (a) The manufacturer's recommendations shall be followed in determining the safe working loads of the various sizes and types of specific and identifiable hooks. All hooks for which no applicable manufacturer's recommendations are available shall be tested to twice the intended safe working load before they are initially put into use. The employer shall maintain a record of the dates and results of such tests.

     (b) Loads shall be applied to the throat of the hook since loading the point overstresses and bends or springs the hook.

     (c) Hooks shall be inspected periodically to see that they have not been bent by overloading. Bent or sprung hooks shall not be used.
