Nevertheless, around 4,000 people die in fires every year in the EU member countries. In many cases, deaths, injuries and major damage to buildings can be prevented if the fire protection requirements are implemented correctly. Therefore, passive fire protec- tion in buildings aims to design, construct, modify and maintain build- ings in such a way that the outbreak of a fire and the spread of flames and smoke (fire spread) are prevented. And, if a fire does occur, it must be possible to rescue people and animals and carry out fire-fighting operations effectively. In terms of fire protection, building service equipment, such as pipe- work and ventilation systems, represents a particular weak point. Pipe- and ductwork passes through separating building elements (walls and ceilings), stairwells and corridors, and thus forms a path along which flames and smoke can spread. In the event of a fire, pipe- and ductwork has a significant impact on safety in buildings and can soon pose a seri- ous threat. The risk potential rises with the number of pipes and their various tasks, thicknesses, materials and media. Therefore, in order to achieve the necessary fire protection targets, service penetrations in separating building elements must be sealed off. These fire protec- tion measures can be carried out in accordance with the less strin- gent requirements of the MLAR (state building regulations) or with an approval. The approval describes the performance in certain applica- tions. For pipe penetration seals with an approval (abP or abZ) easy handling should be ensured and simple installation rules followed. Clearly building services equipment is highly complex and technically demanding. Passive fire protection in this field is a challenge for those responsible for planning the relevant measures. The implementation of these measures requires highly competent firms and careful monitor- ing of the installed systems when residential and other buildings are modernized or constructed. © Armacell Enterprise GmbH & Co.

  • Case Study: Asbestos Joint Compound on Drywall/Sheetrock $100,000.00 Savings
    CASE STUDY: ASBESTOS JOINT COMPOUND ON DRYWALL/SHEETROCK $100,000.00 SAVINGS SCOPE OF SERVICES: AET was contracted by a not-for-profit senior adult community facility to provide asbestos contracting services prior to planned demolition of one of their outdated buildings. An EPA NESHAP inspection of the building had previously identified 24,000 SF of asbestos containing joint compound associated with non-asbestos drywall on the interior walls of the building. The asbestos building inspector had made a recommendation to remove the joint compound and associated drywall prior to demolition. AET was asked to provide a competitive bid for asbestos work along with two other asbestos contractors. AET EXPERIENCE: Joint compound or mud is used to seal joints/seams of the drywall. After application and drying the compound is sanded before being painted. Sanding can create an inhalation hazard from the dust release. Joint compound used before 1980 can contain asbestos. OSHA regulates disturbance/exposure to joint compound and requires this building material to be analyzed separately from the drywall by PLM. The EPA regulates disposal of drywall/joint compound and allows for this combined material to be composited into a single matrix. When analyzed as separate layers by OSHA, the drywall itself rarely contains asbestos and the joint compound where asbestos is found usually contains between 2-4% chrysotile asbestos. However, when analyzed as a composite per EPA protocol, the combined building material (2 layers) rarely exceeds >1% criteria to be defined as ACM. ABATEMENT REQUIREMENTS/COST SAVINGS: AET informed the potential new client that the drywall/joint compound did not have to be removed prior to demolition.

Some insurance industry loss control inspectors are recommending or requiring installation of active fire suppression systems in natural gas compressor buildings without due consideration of fire prevention efforts or costs versus benefits. The objective of this INGAA membership survey was to determine the extent to which insurance and risk management companies are requesting natural gas transmission companies to install active fire prevention controls, what types of active and passive controls are being used, and the incidence of fires. Active fire controls include a method of distinguishing the fire after ignition, whereas passive controls are methods to minimize fire risk or alert operators of a fire or fire condition.

Rocky Mountain Division 7921 Shaffer Parkway Littleton, CO 80127 © 2014 Fire Protection Research Foundation THE FIRE PROTECTION RESEARCH FOUNDATION ONE BATTERYMARCH PARK QUINCY, MASSACHUSETTS, U.S.A. 02169-7471 E-MAIL: [email protected] WEB: www.nfpa.org/Foundation —— Page c —— —— Page ii —— FOREWORD Many NFPA codes and standards, in particular NFPA 400, Hazardous Materials Code, specify separation/clearance distances for hazardous chemical storage and processes from other equipment and occupied buildings. Many of these requirements have historical undocumented origins. Guidance, which may inform a sound technical basis for adjusting these distances, has been requested by NFPA Technical Committees. There are a number of methodologies in the literature, both risk and hazard based, which are used in the chemical safety process safety field that may be relevant to the calculation of these distances. The purpose of this project is to provide guidance to NFPA technical committees on methodologies to develop technically based separation/clearance distances for hazardous chemical storage/processes and their application to the chemical storage and processes. The specific focus of the project is those hazards within the scope of NFPA 400. The Research Foundation expresses gratitude to the report author Dr. Ted Argo and Mr. Evan Sandstrom, who is with Applied Research Associates, Inc located in Littleton, CO. The Research Foundation appreciates the guidance provided by the Project Technical Panelists and all others that contributed to this research effort. Thanks are also expressed to the National Fire Protection Association (NFPA) for providing the project funding through the NFPA Annual Code Fund.

  • Overview of the Legal Design Basis for Passive Fire Protection in Korea and the Direction of Further Development
    Article Overview of the Legal Design Basis for Passive Fire Protection in Korea and the Direction of Further Development Jae-Young Choi and Sang-Hoon Byeon * Department of Health and Safety Convergence Science, Korea University, Seoul 02841, Korea; [email protected] * Correspondence: [email protected]; Tel.: +82-2-3290-5693 Abstract: The design of passive fire protection is applied to minimize the domino effect when a liquid pool fire occurs due to the facilities inside a process plant. In general, the design of passive fire protection has been applied using the API RP 2218 guideline as the basis regardless of the country or owner of the process plant. However, in Korea, legal regulations dictate that explosive areas should be regarded as fireproofing zones rather than following the API RP 2218 guideline. Because liquid pool fires and explosive gas atmospheres are different concepts, it is wrong from an engineering perspective to regard them as the same. Therefore, when a liquid pool fire occurs in a process plant in Korea, it may be more dangerous than in any other countries. In this study, we investigated three categories of fire risk. Korean safety regulations for the design of passive fire protection and others that are not reasonable from an engineering perspective need to be studied and revised. Specifically, Korea needs to revise the design basis of passive fire protection based on the API RP 2218 guideline as a legal standard in accordance with global trends.

  • Passive Firestop Systems Critical for Building Occupants
    10/23/13 4:29 PM Passive firestop systems critical for building occupants By Gregg Stahl Instruments of active fire protection, such as sprinkler systems and fire extinguishers, are a common sight in most buildings – they are always located where building occupants can easily see and access them, if needed. Not as much attention is given to passive fire protection systems, embedded into interior building assemblies, away from public view. However, they are just as integral to the protection of the structure and its occupants in the event of a fire. A key component of commercial building design, passive fire protection's aim is to contain a fire at its source and prevent the spread of flames and smoke throughout a building to allow occupants more time to safely evacuate the structure. The most important area of concentration for these passive fire protection design strategies is the wall assembly, and the most effective mode of passive fire protection is the passive firestop system. Passive firestop systems Fire and smoke can travel through gaps in wall assemblies. Therefore, it is necessary to seal off any wall perimeter joints or penetrations for switches, electrical boxes, power outlets or the passage of pipes, cables or HVAC ductwork with firestop materials. Typically, these materials include: sealants, intumescent materials, sprays, mechanical devices and foam blocks or pillows. It is important to remember that there isn't one universal product that will work for every firestop application. It is also important to select products that have been tested appropriately to meet applicable fire safety standards. The two materials most commonly used in passive firestop systems for today's commercial building projects are sealants and intumescent materials.
