Crawford Draft - Do Not Distribute Further API RP 2001-2011 “Fire Protection in Refineries” – Candidate Ballot Draft 7-23-2011 Updated 8-3/4-2011 FOREWORD API’s Fire Protection in Refineries first edition appeared in 1933 as the beginning of fire safety guidance series for the “downstream” segment. This ninth edition Recommended Practice builds on experience gained over seven decades. The term fire protection used in this publication includes measures taken to prevent fires, as well as those to minimize, control, or extinguish fires already burning. A thorough approach to fire protection starts with an understanding of the ignition and combustion processes, including control of potential fuel sources with an emphasis on containment. This publication gives some basic information on these subjects and identifies sources of more detailed information. While sections of this document discuss general design principles it is not intended as a design manual. Rather, it presents guidance for those providing fire protection services to refineries and gives reference to sources of more detailed design related information. The information presented is based primarily upon experience in a large number of refineries. It is not intended to exclude or limit the use of other approaches of comparable merit. Fire protection references comprise a very large body of literature. API RP 2001 points to many of these references relevant to refineries while seeking not to duplicate them. Most of these references are not incorporated as “normative” and the user is advised to determine their relevance for specific applications. API publications may be used by anyone desiring to do so. Every effort has been made by the Institute to assure the accuracy and reliability of the data contained in them; however, the Institute makes no representation, warranty, or guarantee in connection with this publication and hereby expressly disclaims any liability or responsibility for loss or damage resulting from its use or for the violation of any federal, state, or municipal regulation with which this publication may conflict Suggested revisions are invited and should be submitted to the API Standards Department, 1220 L Street, NW, Washington, DC, 20005 Candidate Ballot Draft for API 2001 9th Edition Updated thru 7-23-2011& 8-3/4-2011 Page 3 of 101 K.

    U.S. EPR FINAL SAFETY ANALYSIS REPORT 9.5 Other Auxiliary Systems 9.5.1 Fire Protection System The purpose of the fire protection system (FPS) is to protect other plant systems and equipment which provide the capability to safely shut down the reactor, maintain it in a safe shutdown condition, control radioactive releases to the environment, and to prevent personnel injury and property damage in the event of a fire. The FPS consists of design features, personnel, equipment, and procedures to provide defense-in-depth protection of public health and safety. The program is implemented during station operations by the prevention, detection, annunciation, confinement, and extinguishment of fire. Administrative controls, training, inspection, testing, and quality assurance (QA) provide reasonable assurance of the operability of the program. The FPS, including administrative controls and the fire brigade, are implemented prior to receiving fuel on site for fuel storage areas and for the entire station prior to reactor startup. 9.5.1.1 Design Basis The FPS is designed in accordance with: ● 10 CFR 50.48 - Fire Protection. ● 10 CFR Part 50, Appendix A, GDC 3 - Fire Protection. ● 10 CFR Part 50, Appendix A, GDC 5 - Sharing of Structures, Systems, and Components. ● 10 CFR Part 50, Appendix A, GDC 19 - Control Room. ● 10 CFR Part 50, Appendix A, GDC 23 - Protection System Failure Modes. ● 10 CFR Part 50, Appendix A, GDC 56 - Primary Containment Isolation. ● NUREG-0800, Standard Review Plan 9.5.1 - Fire Protection Program (Reference 37). ● RG 1.29 - Seismic Design Classification, Revision 4. ● RG 1.189 - Fire Protection for Nuclear Power Plants, Revision 1.

  • Use of Gaseous Suppression Systems in High Air Flow Environments – Phase 1 FINAL REPORT
    Use of Gaseous Suppression Systems in High Air Flow Environments – Phase 1 FINAL REPORT PREPARED BY: Eric Forssell Jensen Hughes Baltimore, MD, USA © September 2015 Fire Protection Research Foundation FIRE PROTECTION RESEARCH FOUNDATION ONE BATTERMARCH PARK | QUINCY, MASSACHUSETTS, USA 02169-7471 E-MAIL: [email protected] | WEB: WWW.NFPA.ORG/FOUNDATION — — Page ii — — FOREWORD Information-technology and telecommunications (IT/telecom) facilities provide critical services in today’s world. From a risk standpoint, the indirect impact of fire loss due to business interruption and loss of critical operations, sometimes geographically very distant from the IT/telecom facility itself, can far outweigh the direct property loss. In the past few years, there have been dramatic changes in the equipment housed in these facilities, which have placed increased demands on HVAC systems. As a result, engineered-airflow containment solutions are being introduced to enhance heat extraction and increase energy efficiency. From the perspective of fire-suppression system design, the use of airflow containment systems creates areas of high-air velocities within an increasingly obstructed equipment space, which could affect the effectiveness of transport of suppression agents throughout the protected volume. Requirements related to use of gaseous-agent fire extinguishing systems in IT/telecom facilities are directly addressed by NFPA 75, Standard for the Fire Protection of Information Technology Equipment, and NFPA 76, Standard for the Fire Protection of Telecommunications Facilities. NFPA 75, 2013 edition, addresses these issues related to gaseous agent systems in several places. 5.6.7 Where aisle containment systems are installed, the existing suppression and detection systems shall be evaluated, modified, and tested as necessary to maintain compliance with the applicable codes and standards.

  • What Properties Matter in Fire-Fighting Foams?
    WHITEPAPER WHAT PROPERTIES MATTER IN FIRE-FIGHTING FOAMS? National Research Institute of Fire and Disaster 2nd NRIFD Symposium - Conference Proceedings Tokyo, 2002 WHAT PROPERTIES MATTER IN FIRE-FIGHTING FOAMS? B.Z. Dlugogorski1, E.M. Kennedy1, T.H. Schaefer2 and J.A. Vitali3 SUMMARY The perfluoroalkyl sulphonate surfactants used in film-forming fire-fighting foams and a range of other applications have been classified as so-called persistent organic pollutants (POPs). The US EPA has recently introduced restrictions which effectively stop further production of perfluoroalkyl sulphonate-based surfactants, such as perfluorooctyl sulphonate (PFOS) and its salts, in the USA. The US EPA has also commissioned a hazard assessment study of perfluorooctanoic acid (PFOA) and its salts, in which the initial findings appear to identify issues that could lead to the potential phase-out of the PFOA surfactants. Thus it seems inevitable that in the foreseeable future the use of fluorinated surfactants will be substantially regulated for all but a small number of critical applications. As a consequence of their highly dispersive use, it is likely that fluorinated surfactants included in fire-fighting foam formulations will be scrutinised closely by environmental authorities around the world. This paper reviews the existing protocols for testing the extinguishment of liquid-fuel fires with aqueous foams. The requirements and objectives of the testing protocols are critically appraised. Subsequently, the paper explains the fire suppression behaviour of foams in terms of the fundamental properties of these materials including their bulk viscosity, yield stress, drainage rate and interbubble gas diffusion (coarsening). The limitation of the spreading coefficient, as presently defined, is also explored, and the need for dynamic measurements of surface tension and surface viscosity is stressed, together with a need to gain a better understanding of the interfacial forces between a hydrocarbon fuel and a spreading foam.
