Fires in wildland-urban interfaces (WUI) are associated with severe negative consequences, such as large community evacuation, property losses social disruption, short- and long-term damage to infrastructure, injuries, and evacuee and responder fatalities. Wildland fires represent an important safety issue in many regions of the world. The future expansion and increased complexity of wildland urban interfaces (WUI) pose severe challenges to community safety from an evacuation perspective.
WUI incidents require a multi-domain approach to assess their impact and the effectiveness of any mitigation efforts implemented. A simulation framework that can establish evacuation performance ahead of time (before responses are implemented), would complement current planning and educational approaches and broaden the scope of the evidence available in a cost-effective way. Such a framework might be used to predict how an evacuation develops based on current and possible future fire conditions, given different affected populations and evacuation decisions and the access/availability of different resources (e.g., road access, public transport, traffic congestion, etc.). To achieve this, the simulation framework would need to represent the core components driving the incident; e.g., a predictive model of residential response, fire development and traffic flow.
A specification for such an integrated platform architecture was developed during a 2017 FPRF research project. The WUI-NITY project aims at developing an integrated software platform for the simulation of wildland-urban interface (WUI) evacuation scenarios that can be used both before an incident for planning and during an incident to inform decisions. The primary application of this platform is the ability to generate dynamic vulnerability maps from coupled fire, pedestrian and traffic sub-models. The webinar will discuss the outcomes from this effort. The final project report will be available on the FPRF website.

In the event of a fire, a sloped ceiling may alter sprinkler performance from expected results for a conventional horizontal ceiling configuration. Prior computational studies investigated the effect of ceiling slope on sprinkler activation times and patterns, and spray dynamics. The role of obstructed ceiling construction and sprinkler orientation were investigated in detail and a test plan for cold-flow and large-scale fire tests was developed. Based on which, cold-flow experiments were conducted using a variety of different sprinklers to examine the impact of ceiling slope and deflector orientation on the measured floor flux. The cold flow test results helped to further refine the test plan for a series of large-scale fire suppression tests conducted with pendent, early suppression, fast response sprinklers under sloped ceilings in presence of obstructed ceiling construction. The large-scale testing and modeling results will provide guidance for updates to sprinkler installation standards. This webinar will discuss the findings from this effort explaining the fire dynamics affecting fire suppression performance under sloped ceilings. The final project report will be available on the FPRF website.
When: Thursday, August 29, 12:30-2:00 pm ET.
The Call for Papers deadline is quickly approaching for SUPDET® 2019, which will be held September 17-20, 2019 at the Crowne Plaza Denver City Center in Denver, CO! Since 1997, the Research Foundation has organized SUPDET (Suppression, Detection, and Signaling Research and Applications Symposium), an annual symposium that brings together leading experts in the field of fire protection engineering for the purpose of sharing recent research and development on techniques used for fire suppression, detection, and signaling. These events are generally attended by a variety of fire protection professionals, such as engineers, researchers, insurers, designers, manufacturers, installers and AHJs.
Please submit your abstracts on new developments in research, technology, and applications for the fire protection community including the following topics. Case studies are always welcome.
Detection and Signaling:
Advancements in Protection of High Hazard Commodities
Developments to Address Environmental Concerns
Protection of Li-Ion Battery Energy Storage Systems
Reliability and Maintenance of Systems (including remote maintenance)
Advancements with Gaseous and Clean Agents
Please submit your abstracts by email no later than March 15, 2019 to email@example.com. Abstracts should be absent of commercial overtones, be based on good science, present objective and credible results, and be without inherent bias. Abstracts that do not meet these criteria will not be accepted.
Abstracts will be reviewed by a program committee. If selected, presenters will be asked to submit an extended abstract, at most 3 pages, for publication in the meeting program or, at the author’s option, a full paper.

Smoke alarm and signaling systems are a proven strategy for reduction of fire fatalities in the general population. However, studies have shown that at risk populations such as the elderly, school age children, alcohol impaired, and those that are hard of hearing do not fully benefit from conventional smoke alarm systems, particularly during sleeping hours. Research has been conducted to develop performance requirements to optimize the waking effectiveness for alarm and signaling systems to meet the needs of these at risk groups. This includes previous research from the Research Foundation on the waking effectiveness of alarms as well as other research. One of the main findings of the Research Foundation work is that the 520 Hz T-3 sound was the most effective signal to awaken hard of hearing participants. Other studies have shown the same results for children and other at risk populations.
Performance requirements for a sound pressure level of 85 dBA at 10 feet from the device for single and multiple-station smoke alarms appear in multiple codes and standards, including UL 217, . This is in contrast to the requirement for UL 268, , listed smoke detectors, which is to emit 75 dBA at the pillow. The 85 dBA specification requires significantly more power, which makes the 520 Hz a particular challenge for alarms operating on a battery/battery backup.
There is a need to review all existing data on this topic to clarify the sound pressure level(s) used in previous research and the background and technical basis for the required sound pressure levels in the codes and standards to determine if a lower sound pressure level could provide equivalent alerting when using a 520 Hz frequency.
Oxygen reduction (or hypoxic) systems are being used in warehouse facilities as an alternative to sprinkler protection. The basic principle of operation is to displace the ambient oxygen in an enclosed environment with one or more nitrogen generators.
The Research Foundation facilitated the project “Review of Oxygen Reduction Systems for Warehouse Storage Applications” as a literature review that helps clarify the current state of oxygen reduction system design and testing. The project also includes a gap analysis comparing current approaches to real-world applications.
To be held Thursday, February 7 at12:30-2:00 pm, the webinar will discuss findings on this effort. Presenters will include:
The Research Foundation has issued an RFP for a project contractor for the Prototype Fuel Load Survey Methodology research project. RFP is available on the Foundation website. The deadline for proposals is January 25 at 5pm Eastern.
