6 Introduction Dividing a building into discrete fire compartments is by far one of the oldest forms of fire protection incorporated into buildings. By separating larger buildings into different fire resistant compartments, areas or cells, either to separate factories from warehouses, plant and equipment from common areas, to divide different levels of high rise buildings, or to separate one townhouse from another, we can effectively increase the life safety of the occupants of the building and limit the extent of the damage to the building and to the business after a serious fire. Effective fire compartment barriers require all openings to be correctly sealed to maintain their fire integrity. This includes larger opening for doors, windows and the like, but just as importantly all openings for services. The sealing of penetrations in fire resistant barriers is commonly referred to as “fire stopping”. This Technical Guide (First Edition) has been prepared by JRAK Consulting and published by the Alliance for Fire and Smoke Containment (pfpa) to provide a basic overview on fire stopping of openings for services. These include fire stopping of penetrations for plumbing, electrical and mechanical service types. The Guide provides specific information relating to fire stopping, covering briefly the Legislative requirements encompassing the Building Code of Australia, the relevant Australian Standards for design, installation, and maintenance. It also introduces the concept of a fire stopping system and discusses some generic types of fire stopping materials . It also includes some basic discussion on training, accreditation and licensing. We would like to stress, that we have prepared this document in good faith to try and provide a starting point for end users, and the Product Guides or Find a Product Tables have been compiled from information provided by the manufacturers and suppliers themselves, and the readers are urged to contact the relevant manufacturers and suppliers and to do their own due diligence in relation to the products listed. We take no responsibility for any errors or omissions and we reserve the right to change this document without any notice. Like any other publication produced by the Alliance for Fire & Smoke Containment, we would be happy to receive constructive criticism and feedback from readers so we can improve future versions. About the Alliance The Alliance for Fire and Smoke Containment (The Alliance) was formed in early 2002 with the support of founding members to provide a uniform and coordinated approach for the passive fire protection industry. The Alliance allows members to deliver relevant information to all building professionals via a web site, writing and disseminating technical papers, seminar presentations, quarterly newsletter and relevant electronic email updates. C o n s u l ta n ts , d e s i g n e r s , i n s t a l l e r s , manufacturers, suppliers and maintenance providers are all encouraged to support and actively participate to improve best practice in the passive fire protection industry by becoming financial Alliance members.

7 Fire Stopping Systems Probably the most fundamental concept covering complying fire stopping; meaning fire stopping that complies with the Legislative requirements and be confidently certified, is that of a fire stopping system. The Fire Resistance Level (FRL) requirements relate to the overall assembly or system as installed, not to the individual components. Figure 1 below, shows pictorially the concept of a fire stopping system, which comprises the complete assembly involving all the relevant components and of course contingent upon compliant installation. Some of the more prevalent components that make up a fire stopping system shown in Figure 1 (below) are discussed in more detail on the following pages. This translates into the concept of a fire resistant fire stopping system. The system includes the fire barrier type that is penetrated, (wall, floor or ceiling), the opening size, the service penetrating the opening, the products used to provide the fire stopping, the installation in accordance with the manufacturers instructions (based on the proprietary fire test information) and effective labelling as appropriate.
