(1) You must provide locks or latches to keep storage bin covers closed, and gaskets or other equivalent devices, to make sure covers are dust tight.
(2) You must make sure employees lock covers in the open position when entering bins. Covers for bins that employees may enter must have a metal fastener (hasp) and lock that can be locked in the "open" position.
(3) You must provide a standard stationary safety ladder on the inside and outside of storage bins with sides more than five feet deep.
(a) The ends of ladders must be kept away from moving screw conveyors.
(b) Outside ladders must reach from floor level to the top of the bin.
(c) Inside ladders must reach from the top of the bin to the bottom of the bin.
(4) You must provide an electric interlock on the main entrance cover of large storage bins near the interior exit ladder. The interlock needs to prevent feed and unloading screw motors from operating while the cover is open.
You may need to follow other requirements found in chapter 296-809 WAC, Confined spaces.
