Section 296-303-02001 - Washroom machines(1) Marking machine. Each power marking machine must be equipped with a spring-compression device of such design as to prevent injury to fingers, should they be caught between the marking plunger and platen; or the marking machine must be equipped with a control mechanism that will require the simultaneous action of both hands to operate the machine; or there must be a guard that will act as a barrier in front of, and which will prevent the operator's fingers from coming into contact with the marking plunger.(2) Washing machine. (a) Each washing machine must be equipped with an interlocking device that will prevent the inside cylinder from moving under power when the outer door on the case or shell is open, and will also prevent the door from being opened while the inside cylinder is in motion. This device should not prevent the movement of the inner cylinder under the action of a hand-operated mechanism or under the operation of an "inching device."(b) Each washing machine must be provided with means for holding open the doors or covers of inner and outer cylinders or shells while being loaded or unloaded. Spring loaded devices are an acceptable means.(3) Extractor. (a) Each extractor must be equipped with a metal cover.(b) Each extractor must be equipped with an interlocking device that will prevent the cover from being opened while the basket is in motion, and will also prevent the power operation of the basket while the cover is not fully closed and secured. This device should not prevent the movement of the basket by hand to ensure an even loading.(c) Each extractor must also be effectively secured in position on the floor or foundation so as to eliminate unnecessary vibrations, and must not be operated at a speed greater than that given in the manufacturer's rating, which must be stamped on the inside of the basket where it is easily visible, in letters not less than one-fourth inch in height. The maximum permissible speed must be given in revolutions per minute.(d) Each engine individually driving an extractor must be provided with an approved engine stop and a speed-limit governor. It is suggested that where an extractor is driven by a direct-current motor a "no field" release be installed to prevent overspeed, which may result from an open or broken field.(4) Power wringer. Each power wringer must be equipped with a safety bar or other guard across the entire front of the feed or first pressure rolls, so arranged that the striking of the bar or guard by the hand of the operator or other person will stop the machine.Wash.
