  • 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 ...

  • 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 ...

  • Swedish solution for high-rise building fires

    Swedish fire fighting nozzle specialists, Unifire AB, have developed what may very well usher in a new era in fire fighting: a fully automatic fire detection and extinguishing system, called FlameRanger. The system, according to Unifire, is capable of detecting and extinguishing a fire in seconds of its breaking out, with minimal use of water, and without any human intervention required. Unifire ...

  • 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 ...

  • Fire Codes: A Foundation of Safety for a Rapidly Changing World

    Chief among these safety features is fire protection. There are myriad codes and regulations relating to fire safety in commercial buildings, from standards on portable fire extinguishers to the installation of stationary pumps for fire protection — the U.S.- based National Fire Protection Agency (NFPA) alone has more than 300 consensus codes that have been adopted in whole or in part ...

  • Optimus® Fired Up for Rocket Noise Testing Project - Case Study

    Airborne Engineering Limited (AEL) specialises in measurement, testing and research; particularly of advanced rocket propulsion systems. One of AEL’s principle services is carrying out static tests of rocket engines for other aerospace companies. AEL is based at Westcott Venture Park, formerly the Rocket Propulsion Establishment, and operates two test bunkers, purpose built in 1949 for ...

  • 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 ...

  • 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, ...

  • Understanding the dangers of combustible dust

    Paper shredding is growing into a big business. Recycling and the green movement certainly planted the seeds, but regulators have added the fertilizer. Industry-changing laws have been passed to govern document security in accounting, healthcare and banking, and shredders of many varieties are becoming the tools of those trades.Five or six years ago Warde Comeaux knew only a few people who ...

  • Selective harmonic frequency–based non–linear load compensation using hybrid active power filter

    This paper presents a hybrid active power filter for harmonics and reactive current compensation while reducing the rating of active power filter. The proposed topology of hybrid active power filter uses the combination of active power filter and a new self–tuned passive filter. The control technique of the proposed system separates the compensation frequency band for active and passive filters. ...

  • Questions You Should Be Asking Before Renting A Wastewater Tank

    When businesses are in need of a wastewater tank or frac tank, many often purchase their own. However, a wastewater tank can collect dust if it’s going unused between company projects. As a result, the purchasing of a wastewater tank may very well feel like a waste of money. Often times it is. Instead of purchasing a wastewater tank, or another kind of tank, such as bolted steel tanks or an ...
