1、 Tentative Interim Amendment NFPA1951Standard on Protective Ensembles for Technical Rescue Incidents2013 Edition Reference: Various TIA 13-1 (SC 13-8-21/TIA Log #1098) Pursuant to Section 5 of the NFPA Regulations Governing the Development of NFPA Standards, the National Fire Protection Association
2、has issued the following Tentative Interim Amendment to NFPA 1951, Standard on Protective Ensembles for Technical Rescue Incidents, 2013 edition. The TIA was processed by the Technical Committee on Special Operations Protective Clothing and Equipment and the Correlating Committee on Fire and Emergen
3、cy Services Protective Clothing and Equipment, and was issued by the Standards Council on August 1, 2013, with an effective date of August 20, 2013. A Tentative Interim Amendment is tentative because it has not been processed through the entire standards-making procedures. It is interim because it i
4、s 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 is subject to all of the procedures of the standards-making process. 1.
