    Module III – Fire Analysis Fire Fundamentals: Definitions Joint EPRI/NRC-RES Fire PRA Workshop August 21-25, 2017 A Collaboration of the Electric Power Research Institute (EPRI) & U.S. NRC Office of Nuclear Regulatory Research (RES) What is a Fire? .Fire: – destructive burning as manifested by any or all of the following: light, flame, heat, smoke (ASTM E176) – the rapid oxidation of a material in the chemical process of combustion, releasing heat, light, and various reaction products. (National Wildfire Coordinating Group) – the phenomenon of combustion manifested in light, flame, and heat (Merriam-Webster) – Combustion is an exothermic, self-sustaining reaction involving a solid, liquid, and/or gas-phase fuel (NFPA FP Handbook) 2 What is a Fire? . Fire Triangle – hasn’t change much… . Fire requires presence of: – Material that can burn (fuel) – Oxygen (generally from air) – Energy (initial ignition source and sustaining thermal feedback) . Ignition source can be a spark, short in an electrical device, welder’s torch, cutting slag, hot pipe, hot manifold, cigarette, … 3 Materials that May Burn .Materials that can burn are generally categorized by: – Ease of ignition (ignition temperature or flash point) . Flammable materials are relatively easy to ignite, lower flash point (e.g., gasoline) . Combustible materials burn but are more difficult to ignite, higher flash point, more energy needed(e.g., wood, diesel fuel) . Non-Combustible materials will not burn under normal conditions (e.g., granite, silica…) – State of the fuel . Solid (wood, electrical cable insulation) . Liquid (diesel fuel) . Gaseous (hydrogen) 4 Combustion Process .Combustion process involves . – An ignition source comes into contact and heats up the material – Material vaporizes and mixes up with the oxygen in the air and ignites – Exothermic reaction generates additional energy that heats the material, that vaporizes more, that reacts with the air, etc.

  • The Art of Reading Smoke for Rapid Decision Making
    The Art of Reading Smoke for Rapid Decision Making Dave Dodson teaches the art of reading smoke. This is an important skill since fighting fires in the year 2006 and beyond will be unlike the fires we fought in the 1900’s. Composites, lightweight construction, engineered structures, and unusual fuels will cause hostile fires to burn hotter, faster, and less predictable. Concept #1: “Smoke” is FUEL! Firefighters use the term “smoke” when addressing the solids, aerosols, and gases being produced by the hostile fire. Soot, dust, and fibers make up the solids. Aerosols are suspended liquids such as water, trace acids, and hydrocarbons (oil). Gases are numerous in smoke – mass quantities of Carbon Monoxide lead the list. Concept #2: The Fuels have changed: The contents and structural elements being burned are of LOWER MASS than previous decades. These materials are also more synthetic than ever. Concept #3: The Fuels have triggers There are “Triggers” for Hostile Fire Events. Flash point triggers a smoke explosion. Fire Point triggers rapid fire spread, ignition temperature triggers auto ignition, Backdraft, and Flashover. Hostile fire events (know the warning signs): Flashover: The classic American Version of a Flashover is the simultaneous ignition of fuels within a compartment due to reflective radiant heat – the “box” is heat saturated and can’t absorb any more. The British use the term Flashover to describe any ignition of the smoke cloud within a structure. Signs: Turbulent smoke, rollover, and auto-ignition outside the box. Backdraft: A “true” backdraft occurs when oxygen is introduced into an O2 deficient environment that is charged with gases (pressurized) at or above their ignition temperature.

  • Common Fire Hazards
    INTRODUCTION TO FIRE INSPECTION PRINCIPLES AND PRACTICES COMMON FIRE HAZARDS TERMINAL OBJECTIVES The students will be able to: 1. Recognize the presence of fire hazards in structures. 2. Recognize the presence of hazardous materials or processes. ENABLING OBJECTIVES The students will: 1. Define fire hazard. 2. Identify types of hazards. 3. Recognize common ignition sources. 4. Recognize and categorize hazardous materials. COMMON FIRE HAZARDS SM FH-2 COMMON FIRE HAZARDS HAZARDS A hazard is something that poses danger, peril, risk, or difficulty. On the golf course a lake can be a hazard. A wet floor can be a slipping hazard. This module covers three other types of hazards: common fire hazards, special fire hazards, and hazardous materials. Part of this module covers fire hazards and part hazardous materials. The term fire hazard is used by both fire professionals and the lay public. What does it mean? Any actions, materials, or conditions that might increase the size or severity of a fire or that might cause a fire to start are called fire hazards. The hazard might be a fuel that is easy to ignite or a heat source like a defective appliance. The hazard could be an action like thawing a pipe with a torch or an omission like failing to have a wood stove chimney cleaned. Common fire hazards are found in most occupancies and are not associated with any special occupancy. Smoking, trash, electrical appliances, storage, and heating are common to most occupancy types. However, smoke-free workplaces are making smoking a less common problem. Special fire hazards are linked to some specific process or activity in particular occupancies.

Pasman 2 1 Department of Chemical Engineering, Delft University of Technology, the Netherlands 2 Mary Kay O’Connor Process Safety Center, Department of Chemical Engineering of Texas A&M University, USA Abstract Particulate fires and explosions cause substantial loss of life and property. With the goal of understanding, preventing, or at least mitigating particulate fire and explosion hazards, we review basics. We distinguish between ‘hazard’ and ‘risk’ and discuss the fire and explosion hazards of particulates, the many factors determining such hazards, hazard indexes, and ways to reduce fire and explosion hazards. While our primary goal is to improve safety, we briefly discuss how fundamental knowledge can be extracted from weapon technology based on particulate combustion. We review the prevention of and protection against particulate explosions and discuss ongoing and future research. Keywords: fire, explosion, (nano)particles, hazard indexes, prevention, protection, modeling 1.

  • Paper 40. Hazards of High Flash Point Liquids in Relation to the Atex 137
    SYMPOSIUM SERIES NO. 155 Hazards XXI # 2009 IChemE HAZARDS OF HIGH FLASH POINT LIQUIDS IN RELATION TO THE ATEX 137 DIRECTIVE Nigel Allen Senior Process Safety Specialist, Chilworth Technology Ltd., Beta House, Chilworth Science Park, Southampton, SO16 7NS Since 1st July 2006 all employers in the EU have to comply with the minimum requirements of “ATEX” Directive 1999/92/EC, commonly known as the ATEX 137 Directive. From Chilworth Technology’s experience it appears that most employers have identified that the risks associated with flammable liquids and combustible dusts need to be assessed under ATEX 137. However, experience also suggests that many employers have not identified that higher flash point liquids can also create explosive atmospheres under certain circumstances: for example, when they are heated, condensed or sprayed to form an aerosol or mist, fractionated, mixed with residues of lower flash point liquids; or undergo reaction or decomposition. The aim of this paper is therefore to raise awareness of the circumstances where high flash point liquids can form explosive atmospheres, and hence are covered by the ATEX 137 Directive. It also aims to provide guidance on carrying out the appropriate explosion risk assessments on the hand- ling of high flash point liquids. To do this it describes incidents involving high flash point liquids, as well as other circumstances where the potential presence of an explosive atmosphere has been over- looked, e.g. in heat transfer fluid and fuel systems. The conclusion is that the ATEX 137 Directive does apply to high flash point liquids in the cir- cumstances described. In conclusion the paper also mentions that, in circumstances where ATEX 137 does not apply (i.e.

  • Outgassing Phenomenon in Flash Point Testing for Fire Safety Evaluation
    OUTGASSING PHENOMENON IN FLASH POINT TESTING FOR FIRE SAFETY EVALUATION Gregory E. Gorbett CFEI, CVFI, Christine Kennedy CFEI, Kathryn C. Kennedy CFEI, Patrick M. Kennedy CFEI, CFPS John A. Kennedy and Associates Fire and Explosion Analysis Experts Sarasota, Florida United States ABSTRACT Accurate ignitable liquid flash point testing provides an important component in the evaluation of a liquid material’s relative flammability danger. Government regulations and industry standards dealing with labeling, warnings, Material Safety Data Sheets (MSDS’s), and transportation and handling of ignitable liquids are frequently based on the physical property of flash point. “Outgassing” in flash point testing is the condition in a flash point test in which nonflammable components of a liquid mixture tend to inert the vapor space being tested, while the evolution of gasses to the atmosphere outside the test cup are ignitable. Outgassing can mask the true flammable nature of a substance. When outgassing occurs during flash point testing, products capable of producing dangerously flammable atmospheres are frequently listed as having no flash point and thereby are classified as non-flammable. This outgassing phenomenon most frequently occurs with liquids that contain certain halogenated hydrocarbons such as Dichloromethane (Methylene Chloride) in mixtures of ignitable liquids. When using industry standard flash point tests in the fire safety evaluation of certain common consumer and industrial products, the phenomenon of outgassing has long been known but frequently overlooked. Improper understanding of this flash point behavior and the inappropriate application of the standards has led to the dangerous mislabeling of consumer products and undue public safety risks. The importance of truly recognizing and understanding the outgassing phenomenon becomes of critical importance when ignitable liquid manufacturers use halogenated hydrocarbon liquids, such as methylene chloride, in an attempt to “inert” an otherwise flammable liquid product.
