(A) Machines and filter assemblies shall be installed within either a liquid tight concrete dike of a four-inch minimum height or within a pan and piping system to contain the solvent should leakage occur. The floor within the dike shall be pitched to drain to a six-inch floor drain or a sump well. The drain or sump well shall be connected to an emergency solvent storage tank and the tank shall be of sufficient capacity to hold all of the cleaning solvent contained in all of the machines installed. Storage tanks shall be suitably vented to the exterior of the building and a minimum of two feet above the roof line.
(B) No machine shall be installed in the same room with any gas, oil or electrically fired equipment. The combustion equipment shall be so installed that all combustion air is drawn directly from the exterior of the plant.
(C) Machines shall be installed in such a manner that only the fronts of the machines are exposed in the customer service area. The maintenance portion of the machines shall be separated from the front of the machines by a solid partition, except for exhaust vents. The partition shall be a wall so constructed that the only access to the maintenance portion of the machines is through one or more doors capable of being locked.
