    1. Scope

    Introduction - When a trade alters a fire separating element, e.g. horizontal assembly or fire barrier or both, by making an opening to install a service element such as a pipe, duct, or wire, there may be multiple trades involved with the process of restoring the hourly rating of that fire separating element. Often the trade responsible for sealing the opening may not be the trade that created the original opening (e.g. a firestop contractor may seal the opening around a pipe installed by a plumber). A Guide is necessary to provide helpful information to both those that test, specify, design, create, seal,and inspect the opening. The waterproofing industry has Guide C1193, which provides information applicable to the use of joint sealants, but it lacks some of the detail necessary to make it truly useful to the firestopping industry. For example, occasionally a pipe may be installed by a plumber that is subjected to water hammer or vibration. If the pipe were installed in a sleeve that provided insufficient annular space to accommodate the vibration, despite the best efforts of the person sealing the opening with caulk or putty, the seal could easily crack or not perform its intended function. The goal of this document is to alleviate problems such as these by creating an industry recognized, consensus document that provides information on best practices.1.1 This Guide describes the use of firestop systems for building applications. Information in this Guide is applicable to most single and multicomponent firestop systems. NOTE 1 Test Method E 814 defines the term: firestop system, na specific combination of penetrating item or items, the specific construction that is penetrated, and the materials or devices, or both, that seal the opening provided to accommodate one or more items that penetrate into or through a fire-resistance rated assembly. 1.2 This Guide relates to the use of firestop systems tested or evaluated to Test Method E 814 or equivalent test methods, such as UL 1479. 1.3 This Guide is intended to provide information regarding the selection and use of firestop system. Information included in this Guide relates to properties and functions of various materials and systems, procedures for cleaning, preparing, and installing components of a firestop system, as well as other environmental concerns and effects that may impact the installation of a firestop system. 1.4 This Guide provides potential solutions or options to various field conditions to maintain the firestop systems various ratings (e.g. F-Rating, T-Rating, L-rating and W-Rating). Due to the range of properties of commercially available firestop systems and products, the information contained herein is general in nature. 1.5 The values stated in inch-pound units are to be regarded as the standard. The SI values given in parentheses are for information only, unless the SI units are used consistently to perform all of the test methods referenced herein. In this case, the SI units will be regarded as the standard.. 1.6 The text of these test methods references notes and footnotes which provide explanatory material and (excluding those in tables and figures) shall not be considered as requirements of this Guide.. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.

    When a trade penetrates a fire-rated barrier with a service element such as a pipe, duct, or wire, there may be multiple trades involved with the process of restoring the hourly rating of the breached barrier. Often the trade responsible for sealing the penetrant may not be the trade that created the original opening (e.g. a firestop contractor sealing the opening around a pipe installed by a plumber). A guide is necessary to provide helpful information to both those that design or create the opening and those responsible for sealing the opening. The waterproofing industry has ASTM C1193, which is chock full of good information applicable to the use of joint sealants, but it lacks some of the detail necessary to make it truly useful to the firestopping community. For example, occasionally a pipe may be installed by a plumber that is subjected to water hammer or vibration. If the pipe were installed in a sleeve that provided insufficient annular space to accommodate the vibration, despite the best efforts of the person sealing the opening with caulk or putty, the seal could easily crack or fail. The goal behind developing this document is to alleviate problems such as these by creating an industry recognized, consensus document that provides information on best practices.
