§ 23.113. Interlocking covers.
(a) Extractors, washers, and tumblers shall be provided with interlocking covers or doors to prevent the inside cylinder from moving when the outer door is open. On extractors, such device shall also prevent the outer door from opening while the inside cylinder is in motion.
(b) Combination drycleaning units, in which the washing and extraction cycles are completed within the same enclosure, shall be provided with splash proof doors, or covers, with interlocking means to prevent cylinder rotation, under power, except for inching at slow speed, when doors or covers are open. During the extracting cycle the automatic mechanical or electrical interlock is designed to prohibit both operating the machine while the cover is open and opening the cover before the basket comes to rest.
