Distillery Storage Dilemmas

May 5th, 2016 Comments off

Distillery DilemmaFire code professionals, businesses and building owners are facing the dilemma on how to successfully address fire protection issues when working on distilleries and storage of distilled goods. NFPA Standards and Fire Codes provide only some of the answers. Despite a considerable number of fire tests and subsequent advancements in the fire and building codes, there is still a need to creatively resolve many of the remaining unanswered questions.

FM Global New High Piled Rack Storage Protections

March 21st, 2016 Comments off

FM GlobalFM Global updated their Data Sheet 8-9 with new high-piled rack storage protection schemes. These new protection options can reduce installation costs by as much as 50%. Large-scale fire tests were used to validate these alternative designs. They demonstrated that large orifice sprinklers and higher flow rates can be successfully applied to not only simplify the sprinkler system but also reduce the total sprinkler water demand. These new protections apply to all commodities including high hazard (plastics) commodities. Read more…

SUPDET 2016 – Conference On Suppression & Detection

March 5th, 2016 Comments off

2015 SUPDET - Suppression, Detection, Signaling ConferenceNFPA’s Fire Protection Research Foundation hosted this year’s conference on suppression and detection in San Antonio, Texas. Presented were the latest research and developments in the fire protection industry that included a diverse cross-section of subjects, such as ‘ESFR K14 sprinklers and High Clearance Update’, ‘Biomass Commodity Classification’, ‘Sub-Scale Analysis of New Large Aircraft Pool Fire-Suppression ‘, ‘Lithium-ion Energy Storage System Fires’ and many more.

Sprinkler Protection Under Sloped Ceilings

December 8th, 2015 Comments off

FM GlobalNFPA’s Fire Protection Research Foundation (FPRF) initiated a project to determine the impact of sloped ceilings on the protection of storage with ceiling slopes steeper than 2-in-12 (equivalent to 9.5 degrees). As part of this effort, FM Global was tasked to conduct fire simulations to better understand issues and risks associated with storage under sloped ceilings. The results of these sprinkler activation and suppression analyses have now been released by FM Global. Read more…

New ESFR Obstruction Test Results

October 12th, 2015 Comments off

FPRFNFPA’s Fire Protection Research Foundation (FPRF) initiated a two-phase study on the effects of obstructions on the ESFR sprinkler system’s ability to suppress fires. Phase one, which was primarily a literature review on the topic, was completed in 2014 and the fire test results from the second phase are now published. The tests were performed on Group A Plastics in rack storage configurations protected by K-17 ESFR sprinklers. Read more…

Polyol Combustion Behavior of Polyurethane Foams

September 29th, 2015 Comments off

Polyurethane FireSince the publication of our article on hazards of polyurethane foam fires, the investigation was extended to gather additional insights into PUF’s combustion behavior and associated combustion processes. As it is known, polyurethane foam under fire decomposes into TDI and Polyol. Specifically Polyol combustion processes are investigated in more detail, because Polyol combustion is responsible for the extremely high heat release rates observed during polyurethane foam fires.

Next Generation In-Rack Sprinklers

September 7th, 2015 Comments off

SFPEIn-rack sprinklers are used when ceiling sprinkler only protection is no longer adequate to protect the rack stored commodities. Well known disadvantages of current in-rack sprinkler designs are (1) additional costs and (2) additional risks of damage of the sprinkler heads during loading and unloading of the racks. Next generation in-rack sprinklers have been UL-tested that are expected to improve on conditions on both fronts. Read more…

2015 NFPA Conference & Expo Presentations Available Online

July 13th, 2015 Comments off

NFPA made available the education session presentations on their website. These free, downloadable presentation decks (in PDF format) offer an excellent opportunity for anyone looking to continue their education, or who could not attend this year’s NFPA Conference & Expo in Chicago. Audio recordings of the sessions are also available (for a nominal fee), which will help you follow along the presentation slides. Read more…

ESFR Protection Of Exposed Expanded Group A Plastics

March 16th, 2015 Comments off

esfrESFR protection of exposed expanded Group A plastics is currently outside the scope of NFPA 13. Attempting to fill this gap, NFPA’s Fire Protection Research Foundation set out to develop experience with these types of commodities and gather data by initiating large-scale fire tests. The goal of these tests was to evaluate the necessary level of protection when ESFR sprinklers in rack storage configurations with no in-rack sprinkler protection are applied. Read more…

Fire Hazards Of Polyurethane Foam

November 3rd, 2014 Comments off

Polyurethane FirePolyurethane foam fires are known to produce very high heat release rates and extremely toxic fumes. As a result, these types of fires provide some unique life, firefighter, property safety and fire suppression challenges. In this study polyurethane foam fires and their combustion processes are investigated using the Fire Dynamics Simulator. The software tool’s predictions were validated against test results from experimental burns. Comparisons between simulation and fire tests demonstrated unprecedented good correlation. This formed the foundation of this study validating the model and providing reliable insights into the nature and sequence of the various combustion events taking place. Read more…
