(a) Each extractor shall be equipped with a metal cover of at least No. 20 gauge, or its equivalent, which shall entirely cover the opening of the outer shell.
(b) Each centrifugal extractor or washer/extractor shall be equipped with an interlock that will disconnect the current to the drive motor and prevent starting rotation of the cylinder when the access door to the machine is open. The interlock shall further prevent opening of the access door or cover while the cylinder is rotating. The interlock shall, however, allow the operator to rotate the basket by manual control or inch the basket for loading or unloading while the access door or cover is open.
(c) The exterior of the basket, including hoops or bands, shall be inspected at least every year to determine condition of basket. The extractor shall be dismantled and the bearings, bearing blocks, and basket shall be inspected at least every two years and all necessary repairs or replacements made. A basket that shows signs of weakness, shall not be used. A record of the inspection, including the date and name of person who made the inspection, shall be kept on file in the plant.
(d) Each extractor shall be equipped with a mechanically or electrically operated brake to stop the basket when the power driving the basket is shut off.
(e) Each squeeze extractor shall be provided with a cover operated by two-hand controls, and an interlock to prevent unloading the machine unless the pressure has been released and also to prevent applying pressure unless the cover has been properly closed. Gages in front of the machine shall indicate the applied pressure. A steam, hydraulic- or pneumatic-operated device shall be provided with a pressure relief valve set to open if the applied pressure exceeds by 10% the maximum operating pressure which shall be shown on the machine nameplate.
