In 1973, fire killed and injured more people in the United States than in any other industrialized nation in the world. The next year, Congress passed the Federal Fire Prevention and Control Act, a landmark bill that made significant investments in fire research, training, and education. Within a few decades, the U.S. had transformed from a fire-prone outlier, to arguably the safest country in the world. 

Today on the podcast, we talk to Dick Gann, one of the most prolific fire researchers in U.S. history, about a new paper that he co-authored that commemorates the 50th anniversary of the Fire Prevention and Control Act. We discuss the legacy of this legislation, and explore several of the research achievements — many of which Gann himself was directly involved with — that have dramatically improved fire safety in the United States over the last half century.

Modern warehouses and distribution centers are huge. Some have footprints larger than 60 American football fields and are filled with densely packed racks up to 100 feet tall. When a giant building like this catches fire, what can firefighters do?    Today on the podcast, we talk to a veteran firefighter and a fire protection engineer who just co-authored a detailed report on the many challenges that the fire service faces in responding these storage fires. We find out what we know, what we need to find out, how modern warehouses are changing, and what fire departments should be doing now to prepare for fires in these giant facilities.    LINKS:

In the last week, huge swaths of metro Los Angeles have been devastated by wildfires fueled by parched vegetation and hurricane force winds. The images and videos of once vibrant neighborhoods reduced to smoldering ash are, in a word, horrifying. Today on the podcast, we try to make sense of what is happening in Los Angeles and what may come next. I talk to NFPA’s wildfire expert Michele Steinberg about the speed of the fires, the response, the lack of water, the evacuation, and the critical decisions that must be made next to ensure that LA is prepared for future wildfires.

You could make the argument that artificial intelligence was the most consequential new technology for fire and life safety in 2024. Several fire departments began dabbling with AI this year, and some even hope to have operational AI in the coming year.

As we head into 2025, we thought it was a good time to revisit our most listened to episode of 2024, Jesse's interview with Preet Bassi, the CEO of the Center for Public Safety Excellence, about how artificial intelligence technologies could impact the fire service. How might fire departments use AI? What are the dangers? What guardrails need to be in place to ensure that the technology is reliable and safe? We pose those questions and many more to Preet.

This summer, long-awaited changes to the standard that sets the performance requirements for smoke alarms went into effect, marking a new era for the technology. For the first time, smoke alarms must now pass a test to show they are resistant to nuisance alarms triggered by cooking smoke. On today’s podcast, smoke alarm researcher Thomas Clearly from NIST joins to discuss the evolution of smoke alarm technology, the challenges of nuisance alarms, and how effective this new generation of smoke alarms are at reduceing nuisance alarms from cooking (4:44). Then, on Code Corner, engineer Shawn Mahoney discusses what NFPA standards say about smoke alarm placement (38:25).

Although hospital fires are rare in the United States, that’s not the case around the world. Recent deadly fires at hospitals in India —including a fire in November that killed 10 newborn babies — show how hard it is to protect these complex facilities. In light of these recent tragedies, we are revisiting an episode from 2020 that looks at the reasons behind the higher occurrences of fire in hospitals around the world, compared to the U.S., and the initiatives and trends that experts hope will help fix the problem.

Nearly all jurisdictions in the United States enforce codes that require two exit stairwells in residential buildings above three or four stories. Housing advocates say that increasing the cap to six stories will lead to better housing options and lower costs. That logic has persuaded lawmakers in some U.S. states to pass laws that raise the allowed height of single exit stair buildings, bypassing state building codes. These changes have alarmed fire officials, who say that having taller buildings with only one stairwell puts the lives of residents and firefighters at risk.

With that as the backdrop, NFPA recently held a symposium where experts from both sides of the debate gathered to make their case and come to a better understanding. Today on the podcast, we talk to an NFPA engineer who helped organize the symposium. She explains the reasoning on both sides of the argument, what was learned from the discussions,  and why single exit stair rules are suddenly such a big deal in statehouses and the code development world.

As online retail flourishes, distribution centers are installing new and more advanced automated storage and retrieval systems (or ASRS). These systems are like enormous vending machines that store, organize, and move product around the facility. The systems save time and space but have also introduced several new fire risks into storage operations. Today on the podcast, we talk to a safety risk consultant and engineer who has worked on numerous ASRS projects. We discuss how these systems work, the safety challenges, and some of the new designs that are keeping fire protection engineers up at night (2:46).    Then, on a new Code Corner, engineer Shawn Mahoney discusses another concern for warehouses: making sure there is enough water supply for their massive fire sprinkler systems (28:52).

When hurricane Ian tore through Florida in September 2022, it left a trail of destruction—but not at Babcock Ranch, a 2,000-home development designed to be both sustainable and to withstand the worst natural disasters. Today on the podcast, we speak to an engineer who lives in and helped design Babcock Ranch about the community’s unique features, as well as the growing trend toward building resiliency and what it could mean for the future of disaster recovery (3:46). This episode first aired in November 2022.   Links

This month, a comprehensive new survey on smoke alarm use in the U.S. found that 16 percent of households—as many as 53 million people—do not having working smoke alarms. The new report comes just in time for Fire Prevention Week (Oct. 6-12), which will focus on smoke alarm use and maintenance. On today’s podcast, two NFPA experts discuss the findings of the new report, and why it is more critical than ever for residents to be educated about how to keep their smoke alarms working (3:04).    Then, on a new Code Corner, engineer Shawn Mahoney tells us what the code says about where to locate smoke alarms in residential homes (33:27).
