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.
