ESFR 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…
Polyurethane 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…
NFPA’s Fire Protection Research Foundation has released a research report on a study of flammability of lithium-ion (Li-ion) batteries in bulk storage. The results of these tests will be used to define appropriate sprinkler protection in NFPA 13 for these types of products. Three types of Li-ion batteries commonly used in various consumer products were chosen for these fire tests. They were stored in rack storage configurations up to 15 ft high. Read more…
On June 27 the Research Foundation and NFPA’s international operations department presented a seminar on research to address high challenge storage protection for aerosols, lithium batteries, flammable and combustible liquids, automated storage and retrieval systems, and others. 110 attendees from 17 nations attended this event in Paris, France to explore the latest global research and emerging trends on storage protection.

The University of California, San Diego is performing one of the largest fire and structural research projects in the United States. Full-scale fire tests will be conducted on May 9th – 11th 2012 to assess the performance of active and passive fire protection systems and impacts and effects of fire spread and smoke movement in an earthquake-damaged high-rise building Read more…
High-volume, low-speed (HVLS) fans require little energy to ventilate large commercial and industrial buildings, and their use can result in considerable cost savings to business owners. But do they compromise fire safety? What are the codes requiring? Read more…
Xtralis, a maker of Aspirating Smoke Detection (ASD) solutions, conducted a series of fire tests in a warehouse setting to demonstrate the capabilities of three smoke detection technologies, an air-sampling solution, a spot-type detector and a beam detector. Read more…
NFPA Conference & Expo attendees got a tour of Underwriters Laboratories in Northbrook, Illinois. During the tour, UL conducted a live fire test in its large-scale fire test and research facility. This particular test involved three rows of rack storage loaded with palettes and cardboard boxes full of Group A plastic cups. A large HVLS Fan was in operation during this fire test. Read more…
NFPA 13 2019 provided a ‘roadmap’ included in the back of the standard for 2019 section cross references for many of the sections found in the 2016 Edition. While this ‘roadmap’ table is useful, it is not a complete reference by any means and as [...]
According to OSHA and the U.S. Chemical Safety Board1 over the last 35 years more than 450 accidents involving dust have killed nearly 130 workers and injured more than 800. Between the years of 2008 and 2012 alone, a total of 50 combustible dust accidents2 [...]
The International Code Council is offering free access to their I-Codes, books and Standards. Previously these documents were only available in internet (html) format. Now the International Code Council has expanded this great service of offering free access to their resources by making many of [...]
The 2013 Edition of NFPA 13 will be adopted by many states and jurisdictions in January 2014. In this article we will be focusing on major changes for this latest edition of NFPA 13 and specifically in the application and use of ESFR (Early Suppression, [...]
ESFR 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 [...]
NFPA’s Fire Protection Research Foundation published a report on large-scale fire tests performed at FM Global for rack storage of Group A Plastics under sloped ceilings with slopes steeper than 2 in 12. An excerpt of this report is presented summarizing the results from these [...]
In-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 [...]
