NFPA 35 Standard for the Manufacture of Organic Coatings 2016 Edition This edition of NFPA 35, Standard for the Manufacture of Organic Coatings, was prepared by the Technical Committee on Manufacture of Organic Coatings. It was issued by the

31、 Standards Council on November 14, 2015, with an effective date of December 4, 2015, and supersedes all previous editions. This edition of NFPA 35 was approved as an American National Standard on December 4, 2015. Origin and Development of NFPA 35 The rst edition of NFPA 35 was developed by the NFPA

32、 Manufacturing Hazards Council and published in 1938 as Suggestions for the Fire Protection of Lacquer Manufacturing Plants. The second edition of this document was published in 1946. The Manufacturing Hazards Council was subsequently disbanded, and responsibility for NFPA 35 transferred to the new

33、Sectional Committee on Coating Manufacture, which operated under the NFPA Committee on Flammable Liquids. The sectional committee undertook a major revision of NFPA 35, expanding its scope to the manufacture of all organic coatings. A new NFPA 35 was published as a Tentative Recommended Practice in

34、1961 and was ofcially adopted by the Association in 1964. The sectional committee subsequently rewrote NFPA 35 as a mandatory standard, which was adopted by the Association in 1970. Revisions to the standard were adopted in 1971, 1976, 1982, and 1987. In 1993, NFPAs Flammable Liquids Project was reo

35、rganized, and the former technical (sectional) committee became an independent committee. The new Technical Committee on Manufacture of Organic Coatings processed a 1995 edition of NFPA 35, which incorporated a signicant revision to the requirements for deagration (explosion) venting as a consequenc

36、e of a major re and explosion incident at a coatings manufacturing plant. After adoption of the 1995 edition of NFPA 35, the Technical Committee on Manufacture of Organic Coatings immediately began a major rewrite of NFPA 35, culminating in the 1999 edition, which included the following amendments:

37、(1) Editorial revision and reorganization to effect editorial improvement and simplication of the text, making it more easily understood and interpreted (2) New building construction requirements to address the hazards of liquid spill res and their impact on load-bearing building supports (3) Improv

38、ed requirements for deagration venting (4) Improvements to the requirements for transfer of ammable and combustible liquids within operating areas (5) Deletion of text relating to open-re resin cooking processes, which are no longer used (6) Guidance on pressure transfer of liquids by air and inert

39、gas (7) Revision and simplication of requirements for special hazards, specically nitrocellulose, monomers, and organic peroxide formulations, including appendix text on handling procedures for nitrocellulose (8) A new chapter, Control of Ignition Sources, with particular attention to static electri

40、city hazards and bonding and grounding requirements (9) Another new chapter, Management of Fire Hazards The 2005 edition of NFPA 35 incorporated the following amendments and improvements: (1) Editorial revisions to comply with the Manual of Style for NFPA Technical Committee Documents (2) Adoption o

41、f preferred denitions from other NFPA technical documents where such adoption did not conict with the intent and context of NFPA 35 (3) Clarication of the requirements for process building heatingMANUFACTURE OF ORGANIC COATINGS 35-2 2016 Edition (4) Requirements for “hot box” installations and drum

42、heaters used to heat containers of viscous liquids (5) Improved requirements for proper handling of nitrocellulose, including guidance on safe movement using hand trucks and powered industrial trucks (6) A requirement that all res must be investigated to determine their cause (7) A new table, Table

43、A.5.6.3, to provide guidance for electrical area classication that is specic to equipment and processes that manufacture organic coatings The 2011 edition of NFPA 35 incorporated the following major amendments and improvements: (1) Denitions for kettle, thin-down tank, normal vent, and emergency rel

44、ief vent were added to aid the user in the application of the provisions of this standard and to reect usage of these terms within the context of the organic coatings industry. (2) The specic requirements in 5.1.6 for means of egress were replaced with a direct reference to NFPA 101, Life Safety Cod

45、e. (3) Section 5.4, Ventilation, was completely revised as suggested by the U.S. Chemical Safety and Hazard Investigation Board (CSB), based on their report on the CAI/Arnel explosion and re that occurred November 22, 2006, in Danvers, MA. The new requirements in this section correlated with the pro

46、visions of NFPA 30, Flammable and Combustible Liquids Code. Also, these new requirements were applicable to both Class I (ammable) liquids and Class II or Class III (combustible) liquids that are heated up to or above their ash points. (4) A new paragraph, 6.6.4.1, required safe operating temperatur

47、e limit controls for mixing tanks in which contents are heated. This paragraph also was based on suggestions submitted by the CSB as a result of its report on the CAI/Arnel explosion and re. The 2016 edition of NFPA 35 incorporates the following amendments and improvements: (1) The term antistatic h

48、as been changed to static dissipating throughout the standard to remove a term no longer used in the electrostatics community and more accurately describe the property being addressed. (2) Building feature requirements, such as walls without unprotected openings and the prohibition of basements, hav

49、e been claried. (3) Exceptions have been rewritten as mandatory language as recommended by the Manual of Style for NFPA Technical Committee Documents.COMMITTEE PERSONNEL 35-3 2016 Edition Technical Committee on Manufacture of Organic Coatings George A.
