This Section includes through - penetration firestop systems for penetrations through fire- resistance- <br />rated constructions, including both empty openings and openings containing penetrating items. <br />1.2 PERFORMANCE REQUIREMENTS <br />A. General: For penetrations through fire - resistance -rated constructions, including both empty <br />openings and openings containing penetrating items, provide through- penetration firestop systems <br />that are produced and installed to resist spread of fire according to requirements indicated, resist <br />passage of smoke and other gases, and maintain original fire- resistance rating of construction <br />penetrated. <br />B. Rated Systems: Provide through - penetration firestop systems with the following ratings <br />determined per ASTM E 814 or UL 1479: <br />1. F -Rated Systems: Provide through - penetration firestop systems with F- ratings indicated, but <br />not less than that equaling or exceeding fire- resistance rating of constructions penetrated. <br />2. T -Rated Systems: For the following conditions, provide through- penetration firestop <br />systems with T- ratings indicated, as well as F- ratings, where systems protect penetrating <br />items exposed to potential contact with adjacent materials in occupiable floor areas: <br />a. Penetrations located outside wall cavities. <br />b. Penetrations located outside fire- resistance -rated shaft enclosures. <br />C. For through - penetration firestop systems exposed to view, traffic, moisture, and physical damage, <br />provide products that, after curing, do not deteriorate when exposed to these conditions both during <br />and after construction. <br />1. For floor penetrations with annular spaces exceeding 4 inches in width and exposed to <br />possible loading and traffic, provide firestop systems capable of supporting floor loads <br />involved, either by installing floor plates or by other means. <br />D. For through - penetration firestop systems exposed to view, provide products with flame - spread and <br />smoke - developed indexes of less than 25 and 450, respectively, as determined per ASTM E 84. <br />1.3 SUBMITTALS <br />A. Product Data: For each type of product indicated. <br />B. Shop Drawings: For each through - penetration firestop system, submit documentation, including <br />illustrations, from a qualified testing and inspecting agency, showing each type of construction <br />condition penetrated, relationships to adjoining construction, and type of penetrating item. <br />1. Where Project conditions require modification to a qualified testing and inspecting agency's <br />illustration for a particular through - penetration firestop condition, submit illustration, with <br />modifications marked, approved by through - penetration firestop system manufacturer's fire - <br />protection engineer as an engineering judgment or equivalent fire- resistance -rated assembly. <br />C. Qualification Data: For Installer. <br />Reece, Noland & McElrath, Inc. 237000-1 Orange County Board of Elections <br />Orange Co., NC 05/04/18 <br />
