2、dition Reference: 5.4.4(8) (New), 8.27.4.2 and A.8.27.4.2 (New) TIA 13-4 (SC 14-10-6 / TIA Log #1159) Pursuant to Section 5 of the NFPA Regulations Governing the Development of NFPA Standards, the National Fire Protection Association has issued the following Tentative Interim Amendment to NFPA 1971,
3、 Standard on Protective Ensembles for Structural Fire Fighting and Proximity Fire Fighting, 2013 edition. The TIA was processed by the Technical Committee on Structural and Proximity Fire Fighting Protective Clothing and Equipment and the Correlating Committee on Fire and Emergency Services Protecti
4、ve Clothing and Equipment, and was issued by the Standards Council on October 28, 2014, with an effective date of November 17, 2014. A Tentative Interim Amendment is tentative because it has not been processed through the entire standards-making procedures. It is interim because it is effective only
5、 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. Add a new 5.4.4(8) to read as follows: (8) A statement that the moisture barri
6、er has not been evaluated for all chemicals that can be encountered during fire-fighting operations and information that the effects of chemical exposure on the moisture barrier are to be evaluated per the inspection procedures in NFPA 1851. 2. Revise 8.27.4.2 and add a new Annex A.8.2.7.4.2 to read
7、 as follows: 8.27.4.2 Each of the following liquids shall be tested separately against each test specimen: (1) Aqueous film-forming foam (AFFF), 3 percent concentrate (2) Battery acid (37 percent by weight sulfuric acid to water) (3)* Fire-resistant hydraulic fluid, phosphate ester base that does no
8、t contain aliphatic phosphates (4) Surrogate gasoline fuel C as defined in ASTM D471, Standard Test Method for Rubber Property Effect of Liquids, a 50/50 percent by volume of toluene and iso-octane (5) Swimming pool chlorinating chemical containing at least 65 percent-free chlorine (saturated soluti
9、on). A.8.27.4.2(3) The types of liquids, specifically the hydraulic fluid liquid, were liquids that were identified as being in use or that could be encountered by the fire service in the early 2000s. These liquids may not represent current day fire service use. While fire-resistant hydraulic fluid
10、is still in use today, the industry has been transitioning to hydraulic fluids based on mineral oils. Research has shown that the identification of fire-resistant hydraulic fluid, phosphate ester base that does not contain aliphatic phosphate is a better representation of this type of fluid for conducting the liquid penetration resistance test.
