  • J566 fire suppression unit

    Client: Sporting Edge Area: Norway & Dubai We were approached by Sporting Edge to build a Fire Suppression unit that would be incorporated in a large data centre in Oslo and also another unit for Dubai. These units replaced the ‘argon dump’ systems currently installed, thus making the data centres safer. The Fire Suppression system takes the oxygen ...

  • Experience with Fire Suppression Installations for Wood Churches in Sweden

    During the last 100 years, approximately one church per year has been destroyed by fire in Sweden. When a church is lost to fire, invaluable artifacts vanish, both material and immaterial. Churches are important symbols and the cultural-historical value is in most cases very high. The installation of a fire suppression system is often the best measure for improving fire protection. This paper ...

  • If the fire doesn’t kill you, the CO2 might – carbon dioxide and fire suppression

    Carbon dioxide (CO2) has been used in fire extinguishers and fire suppression systems for more than a hundred years. In high concentrations it dilutes oxygen, thus removing one of the three elements of the combustion triangle (the other two being heat and fuel). It is also cheap, widely available, odourless, colourless, electrically non-conductive, chemically inert and it leaves no residue. It is ...

  • Experimental Study of Suppressing PVC Fire with Water Mist using a Cone Calorimeter

    Effect of water mist on the small-scale solid fuel PVC (poly vinyl chloride) fire in a confined space has been studied experimentally using a cone calorimeter. In this study, the combustion characteristics of PVC, and the interaction between the water mists and the diffusion flame in a confined space with proper ventilation control are studied under various conditions in the cone calorimeter. The ...

  • Forest Fires in Europe 2005

    The European Union is supporting since the Eighties the efforts implemented by Member States to fight forest fires in all their stages: prevention, suppression and restoration. That’s because forest fires can severely affect all the functions developed by the forests of the Community from the economic, ecologic and social point of view; they can also better and more effectively be counteracted ...


  • Importance of Dry Risers for Fire Safety

    Fighting fires in high rise buildings is challenging. It would not be possible for firemen to just aim their hoses from the ground floor and hope to reach those floors that are higher up. It would also not be feasible for them to run up flights of stairs trailing a hose behind them. Many high rise buildings can have twenty floors or more and a fire can happen anywhere. The ability to get water to ...

  • Fires at Composting Facilities: Causes and Conditions

    The subject of fires at composting facilities is a bad news/good news situation. The bad news is that fires are more common than we realize. Ask a group of facility operators if they have had to deal with a fire, and the majority will quietly admit they have. The good news is that we don’t realize that fires are fairly common at composting facilities. Most are neither frequent nor destructive ...

  • Fire Protection of Heritage Structures: Use of a Portable Water Mist System under High-altitude Conditions

    In order to verify the application of water mist on fire protection of the Potala Palace in Tibet and deepen the knowledge of its suppression mechanisms under high-altitude conditions, a series of experiments are performed with a portable water mist fire protection system and with diesel oil, gasoline and, in Lhasa, ghee as fuels. All of the experimental tests are conducted with and without ...

  • Experimental Study of the Fire-extinguishing Effectiveness of 1-Bromo- 3,3,3-Trifluoropropene/Nitrogen Mixtures

    The search for a new fire-extinguishing agent with all the desirable properties of Halon 1301 has not been successful. In this study, the authors have pursued the development of 1-bromo-3,3,3-trifluoropropene (BTP), which has a very low extinguishing concentration, but with its high boiling point, it is not a suitable replacement for Halon 1301. However, mixtures of BTP in an inert gas could ...

  • A Numerical Study of Firebrands Scattering in Urban Fire Based on CFD and Firebrands Aerodynamics Measurements

    Firebrands are found to be an important factor in the spread of large urban fire. In this study, in order to predict the scattering of firebrands in an urban fire, a computational fluid dynamics (CFD), turbulent combustion model, radiation model, and firebrand scattering model are coupled and it is validated by a fire wind tunnel experiment. The density, terminal velocity, and Stokes diameters of ...

  • Field Model Analysis and Experimental Assessment of Fire Severity and Smoke Movement in a Partitioned and a Non-partitioned Dwelling Unit

    Inter-compartment smoke spread in a dwelling unit is greatly impeded by the presence of partition walls. For the same fire load and floor area, smoke movement and associated fire severity for a non-partitioned (NP) unit are different from those of a partitioned (PT) unit. To study the smoke movement and gas temperature evolution, computational fluid dynamics (CFD) analysis is carried out for a ...

  • Effects of mechanical harvest plus chipping and prescribed fire on Sierran runoff water quality

    Received for publication September 14, 2007. Fire suppression in Sierran ecosystems creates a substantial wildfire hazard and may exacerbate nutrient inputs into Lake Tahoe by allowing the buildup of O horizon material, which serves as a source for high N and P concentrations in runoff water. The purpose of this study was to evaluate the effects of biomass reduction using cut-to-length mechanical ...

  • Surface Coating and Metal-Based Organic Additives—Approaches for FRSS PVC Cables

    Polyvinyl chloride (PVC) is one of the most widely used polymers today. One of its major applications is in electrical and control cables. Although PVC is intrinsically self-extinguishing, it supports flame spread along its length because of the additives used during processing. The spread of fire along electrical cables may be alleviated either by using flame-retardant smoke-suppressant (FRSS) ...

  • ESFR Sprinkler Protection of Class II Commodity in Cold Storage Warehouses using Propylene Glycol Antifreeze Agent

    Currently, the NFPA standard for the installation of sprinkler systems (NFPA 13) requires that early suppression fast response (ESFR) sprinklers be specifically listed for use with antifreeze mixtures due to the concern that antifreeze will contribute to the combustion energy of the fire. The effectiveness of an ESFR sprinkler system in suppressing a fire depends on the antifreeze concentration, ...

  • Quantification of the number of injured people due to hazardous material accidents

    Accidents with hazardous materials may threaten the lives of people living in the direct environment of the transportation infrastructure. In many countries, fire brigades play a major role in advising the authorities when they are dealing with issues where hazardous materials are involved. Since emergency responders have to deal with injured persons, information concerning the number of injured ...

  • Corrosion of Electronic Components by Hydrogen Fluoride

    Generation of hydrogen fluoride (HF) from fire suppression by some gaseous agents is a major concern, because HF causes corrosion. Without proper precautions, the HF corrosion damage to some electronic facilities can be significant. A study has been carried out to evaluate the corrosion effect of HF on electronic equipment. This article describes details of the corrosion study in terms of test ...
