1、 Tentative Interim Amendment NFPA400 Hazardous Materials Code 2016 Edition Reference: Table 5.2.1.6 and Table 5.3.7 TIA 16-2 (SC 16-4-11 / TIA Log #1213) Pursuant to Section 5 of the NFPA Regulations Governing the Development of NFPA Standards, the National Fire Protection Association has issued the
2、 following Tentative Interim Amendment to NFPA 400, Hazardous Materials Code, 2016 edition. The TIA was processed by the Technical Committee on Hazardous Chemicals, and was issued with a correction by the Standards Council on April 6, 2016, with an effective date of April 26, 2016. A Tentative Inter
3、im Amendment is tentative because it has not been processed through the entire standards-making procedures. It is interim because it is effective only between editions of the standard. A TIA automatically becomes a public input of the proponent for the next edition of the standard; as such, it then
4、is subject to all of the procedures of the standards-making process. 1.
