Access to the machine service area shall be gained through doors equipped with locks and shall be kept locked at all times. The wall shall be designed to allow an air flow from the public area to the machine service area through grilles or ducts located as close as practicable to the machines, and sized on the basis of 500 c. f. m. per square foot of grille area.
(j) Exhaust System. All coin-operated dry cleaning machines shall be equipped with an exhaust system capable of maintaining a minimum of 100 feet per minute face velocity through the loading door when opened. This system shall terminate at vent stacks projecting not less than five feet above the roof. These stacks shall be located not less than fifteen feet from any air intake, shall not be closer than twenty-five feet to any opening of any building or within 100 feet of a residential dwelling. Such machines shall also be equipped with one or more two-inch scavenger pipes, or the equivalent, extending to a point not less than six inches from the floor and connected to the machines' exhaust system.
(k) Required Equipment. All coin-operated dry cleaning machines shall be equipped with an interlock system to prevent the loading door from being opened during the normal cycle of the machine. This system shall be either electrical or mechanical and should be constructed so that in the event of malfunction it shall fail safe. Such machines shall also be equipped with lint traps.
(l) Ductwork. All ductwork in any premises in which there is conducted coin-operated dry cleaning must be sealed (soldered or taped) and all discharge stacks must extend to a minimum of five feet above the roof line.
(m) Minimum Air Flow Rate. All premises in which there are located coin-operated dry cleaning machines must be equipped with an exhaust system capable of maintaining a minimum flow rate of air from the customer area through the partition required in subsection (i) hereof to the machine service area as follows:
Number of Machines Minimum Air Flow Rate per Machine (C. F. M.)
1 - 3 500
4 - 8 400
9 - 16 375
17 or more 360
(n) Emergency Ventilation Equipment. The machine service area of any coin-operated dry cleaning machine site shall be equipped with one or more general ventilation fans to be used only in the event of solvent leakage or other emergency.
