Steam Fire Lines. Every dry cleaning building in which a flammable solvent having a flashpoint below 140 degrees Fahrenheit (closed cup tester) is used shall be provided with a high pressure steam boiler having a capacity of one horsepower for each 100 cubic feet contained in the largest dry cleaning room in the building. Such boiler shall be arranged and equipped to permit a steam pressure of not less than 30 pounds per square inch being maintained at all times during which dry cleaning operations are carried on in the building. Each dry cleaning room in the building shall be connected to such boiler by a steam pipe of not less than one and one-half inch diameter, either by a direct line to each room, or by a main or mains with branches.
