Standard Guide for Understanding and Using Information Related to Installation of Firestop Systems

Importancia y uso:

4.1 The information contained in this guide is general in nature because of: the great number of commercially available firestop systems globally; the quantity and variety of internationally published firestop system’s listings; worldwide variations in building and fire code requirements; and the many conditions and applications associated with a firestop system’s use.

4.2 This guide provides general information and guidance that is primarily used by firestop contractors and firestop industry inspectors of a firestop system. However, this guide should also be used by others, such as architects, engineers, specifiers, etc. Some of the information referenced in this guide provides resources for additional information not contained in the manufacturer’s installations, the firestop system’s test report, and listing. Information contained in this guide also allows a single source for a general comparison of firestop materials used during the installation of firestop systems.

4.3 This guide discusses general procedures, such as substrate cleaning and priming, as well as installation of the components of a firestop system.

Note 2: The term “substrate” has a particular meaning in engineering. A substrate is defined as the “basic surface on which a material adheres, for example, paint or laminate.”19

4.4 This guide explains the general properties and functions of various penetrating items and firestop materials.

4.5 This guide presents general guidelines for the application of the various materials used in the installation of a firestop system for a specific application, and environmental conditions and effects that are known to potentially affect a firestop system’s installation.

4.6 This guide is intended to be read completely at least once, and each of the Sections 1 through 19 should be read in their entirety to avoid misunderstanding and misapplication.

4.7 This guide may20 also provide some value to users of IMO Safety of Life at Sea (SOLAS) and other International Maritime Organization (IMO) documents, including the IMO FTP Code, on fire testing firestop systems, also known as “penetration systems.”

4.8 This guide is not an all-inclusive document. It is intended to address common sources for planning, preparation, and installation of firestop systems. References to other documents made herein contain important information and details that provide more in-depth knowledge of firestop systems and their installation.

4.9 This guide does not provide all of the specific information that is typically described in test reports, listings, or judgments with justifiable technical rationale for specific applications of firestop systems.

4.10 This guide is not a firestop system’s installation manual.

Note 3: The firestop system’s manufacturer should be consulted about applications for their firestop materials, including their proper storage, use, and installation.

4.11 This guide does not provide detailed information about the firestop system’s inspection process or provide specific information about firestop industry inspector’s qualifications and competence.

Note 4: Practice E2174 provides a method for on-site inspection of firestop systems. The ICC International Building Code references Practice E2174 under requirements for special inspections. Practice E3038 provides information for assessing and qualifying candidates as firestop industry inspectors of firestop systems based on the candidate’s competence.

4.12 Except as discussed in 6.8, this guide does not provide information about “blank openings,” which involve an opening that is sealed with firestop materials but does not have any penetrating items.

4.13 Test reports, listings, and judgments with justifiable technical rationale do not normally contain all the information needed related to the aging, environmental, mechanical, and physical properties of the firestop system; or the longevity, durability, and performance of the firestop system. This guide offers some resources to ascertain this supplemental information because these characteristics can affect the firestop system’s installation and performance.

Note 5: Some information related to these performance characteristics of firestop systems or firestop materials is also found in: Test Method E2785, which tests for exposure of firestop materials to environmental conditions; Test Methods E2786, which measures expansion of intumescent materials used in firestop systems; and Practice E2923, which measures the relative movement capabilities of through-penetration firestop systems. Still, other performance characteristics of the firestop system can be specified that are not contained in firestop system’s test report or listing may also be required, such as surface flammability and smoke attributes determined by Test Method E84 or other similar standards (for example, CAN/ULC-S102, EN 13501-1, NFPA 255, UL 723, etc).
