The May/June issue of NFPA Journal includes several features on changes to important NFPA codes and standards, including updates to the 2019 edition of NFPA 72®, National Fire Alarm and Signaling Code®.
In “Smarter About Smoke,” Richard Roux, staff liaison for NFPA 72, outlines a handful of key changes to the code, including the addition of a date: January 1, 2022.
“That’s the day NFPA 72 will require all new installed household smoke alarms to meet listing specifications to distinguish between smoke generated by routine cooking and smoke generated by potentially more serious sources, such as furniture,” Roux writes. “This push to develop more discriminating smoke alarms is a direct response to the problem of nuisance alarms, which leads many residents to remove alarm batteries or entire alarms, significantly increasing occupants’ risk of death or injury in a home fire. The listing requirements were developed by UL at its new testing facility, and the inclusion of the date in the new NFPA 72 underscores what is arguably the most important lifesaving change in smoke alarms since their introduction in the 1960s, along with codes to require their installation.”
Roux also looks at the integration of NFPA 720, Installation of Carbon Monoxide (CO) Detection and Warning Equipment, into NFPA 72; developments related to fire service access elevators and occupant evacuation elevators; communications methods for forwarding signals from protected premises to supervising stations; and enhancements to Class N pathways.
The story also includes info on four education sessions on NFPA 72 scheduled for the NFPA Conference & Expo in Las Vegas.

The following proposed Tentative Interim Amendment (TIA) for the 2018 edition of NFPA 68, Standard on Explosion Protection by Deflagration Venting, is being published for public review and comment:

 


Anyone may submit a comment on this proposed TIA by July 19, 2018.  Along with your comment, please identify the number of the TIA and forward to the Secretary, Standards Council by the closing date.

This webinar will present the fire safety challenges of tall wood buildings, specifically discuss the contribution of Cross Laminated Timber (CLT) building elements. Under the auspices of the Fire Protection Research Foundation, the second phase research on fire safety challenges of tall wood buildings was conducted to quantify the contribution of cross-laminated timber (CLT) building elements in compartment fires. The research encompassed literature review, experiments and modeling. Based on gap identification in the literature review, a series of full-scale CLT compartment fire tests were designed and conducted under various exposure conditions and produced a large amount of experimental data including heat release rates, heat fluxes, char patterns and char depths. The experimental data were analyzed and used to quantify the contribution of CLT building elements to compartment fires. Additionally, an intermediate scale fire testing method was developed to identify adhesives that lead to an improved fire performance and a reduced contribution of CLT to the fire. An engineering calculation method, validated using the experimental results, was refined to predict the influence of exposed CLT on the severity and the duration of compartment fires. The technical data developed from this project will enable designers to develop a fire protection strategy to mitigate the potential hazard to occupants, fire fighters and property. Full final reports on this research are available from the Foundation's website.
When: Wednesday, May 30, 12:30-2:00 pm EDT
Presenters: Joseph Su, Ph.D., National Research Council of Canada, and Daniel Brandon, Ph.D., Research Institutes of Sweden (RISE) 
If you would like to hear more from Joseph Su and Daniel Brandon on this topic, as well as other thought leaders, please plan to attend the NFPA Conference & Expo® - June 11 - 14, Las Vegas - one of the world’s largest and most comprehensive fire, electrical, and life safety education events. For details visit www.nfpa.org/conference.
Dr. Joseph Su is a Principal Research Officer, Group Leader at the National Research Council Canada’s Fire Safety Unit. He has over 30 years research experience in combustion chemistry, fire development, fire detection and suppression, fire performance of materials and systems and full-scale fire testing with over 200 publications. Currently, he serves as the International Convener of ISO/TC92/SC3/Working Group 2 (Generation and Analysis of Fire Effluents). He was a recipient of the 2000 Jack Bono Engineering Communications Award from the Society of Fire Protection Engineers.
Dr. Daniel Brandon works as a researcher at Research Institutes of Sweden - Fire Research. He has a PhD degree from the University of Bath in the UK, where he studied the behavior of timber connections in fire and ambient conditions. He is currently leading national and international research projects on fire safety in timber buildings. Furthermore, he is a Swedish delegate in the Eurocode CEN SC5 committee, dealing with the revision of the European standardization for Structural Fire Design of timber structures. Recently, he received the Howard medal for best paper from the Institution of Civil Engineers.
