NFPA 32 Standard for Drycleaning Facilities 2016 Edition This edition of NFPA 32, Standard for Drycleaning Facilities, was prepared by the Committee on Textile and Garment Care Processes. It was issued by the Standards Council on November 14, 2015, with
31、an effective date of December 4, 2015, and supersedes all previous editions. This edition of NFPA 32 was approved as an American National Standard on December 4, 2015. Origin and Development of NFPA 32 This standard was originally prepared by the Committee on Flammable Liquids in 1924 and 1925 in co
32、operation with the National Association of Dryers and Cleaners. The rst edition was adopted in 1925 in cooperation with the National Association of Dryers and Cleaners. Amendments were adopted in 1927; completely revised editions were issued in 1936, 1944, and 1956; amendments were adopted in 1964;
33、a completely revised edition was issued in 1970; amendments were adopted in 1972; and completely revised editions were issued in 1974 and 1979. There was a minor amendment in the 1985 edition, which was reconrmed in 1990, and minor changes were adopted for the 1996 edition. For the 2000 edition, gen
34、eral requirements for all plants, regardless of solvent in use, were moved to the front of the standard. There was better correlation of the requirements for each plant type with the relative hazards potentially present. Various protection requirements were made less stringent in cases where a plant
35、 had reduced quantities of solvent in combination with various redundant safety systems for the equipment. Requirements were added to address machine conversion to allow a machine to use another solvent, as was a common occurrence in the industry. For the 2004 edition, additional guidance and deniti
36、ons were added to better dene and explain machine conversions made to allow for use of a different class of solvent. For the 2007 edition, new options were added to allow for increasing the maximum concentration to 60 percent or below of the LEL with adequate automatic instrumentation and safety int
37、erlocks in accordance with NFPA 69, Standard on Explosion Prevention Systems. Also, new requirements were added for drycleaning using nonammable liqueed gases in pressure vessels, including, but not limited to, carbon dioxide solvent technologies. A chapter was added for new requirements for laundry
38、 equipment in drycleaning plants. For the 2011 edition, the Committee added new denitions for laundry, laundry dryer, and wet cleaning and revised the denition of Class IV solvents. The requirements for employee training and the inspection frequency for re protection systems were revised to be in ac
39、cordance with NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, and requirements for boiler room separation by barrier walls in accordance with NFPA 5000, Building Construction and Safety Code, were added. The requirements for temperature control
40、for laundry dryers to accommodate a cool-down period, to eliminate the potential for spontaneous combustion within the dryers, also were revised. The 2016 edition of NFPA 32 has been reorganized and includes signicant changes that establish requirements based on two variables: the class of solvent a
41、nd the type of equipment used. The Committee recognized that NFPA 32 had many requirements initially established for ammable solvents and older technologies that had been retained in the document over the years. It was not always clear which requirements applied only to lower classes of solvents and
42、 older technologies. The 2016 edition reects changes that have occurred in both the solvents and the equipment used by the drycleaning industry that impact safety. The requirements are less stringent for facilities that use higher classes of solvent and equipment and that have built in re protection
43、 features than for those facilities that use lower classes of solvents and older equipment. NFPA 32 now denes four “versions”DRYCLEANING FACILITIES 32-2 2016 Edition of equipment, Versions I through IV, and establishes requirements that are based on both the version of equipment and the solvent clas
44、s used rather than on the solvent class alone. The standard has been reorganized to place requirements applicable to all drycleaning facilities in Chapters 4 through 6. Additional requirements, located in Chapters 7 through 9, are dependent on the lowest class of solvent used in a particular facilit
45、y. Requirements in those latter chapters are dependent on the versions of equipment used within the facility. A ow chart has been added as a new Annex B to direct users and AHJs to the applicable requirements. Equipment construction requirements have been removed since drycleaning equipment is requi
46、red to be listed, and the requirements for Class IIIA and Class IIIB have been combined. This edition of NFPA 2016 also addresses emerging re safety concerns related to the conversion of equipment and solvents. With the increasing regulation of perchloroethylene, drycleaning facilities might decide
47、to change to new solvents or new equipment. The 2016 edition of NFPA 32 prohibits the use of lower class solvents in existing equipment designed for higher solvent classes and requires AHJ notication for any changes in solvent class. NFPA 32 also establishes requirements for changes within the same
48、solvent class to ensure that the new solvent is compatible with the equipment. The solvent manufacturer is now required to certify the ash point and ammable limits of the solvent under anticipated conditions of drycleaning operations and must provide the facility with written instructions on proper
49、use and safe handling of the solvent. Dedication The Technical Committee dedicates the 2016 edition of NFPA 32 to the memory of James “Jimmy” DeSanto, a former Committee member who grew up working in and eventually running his fathers drycleaning plant in Illinois. Jimmy devoted his life to the industry and to helping drycleaners across the United States. Jimmy had a passion for the industry, never met a stranger, and always brought smiles and laughter to any situation.COMMITTEE PERSONNEL 32-3 2016 Edition Technical Committee on Textile and Garmen
