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).LINKS

In most years, more firefighters die by suicide than from accidents or injuries that happen in the line of duty, according to the Firefighter Behavioral Health Alliance. It’s well understood that PTSD is a huge contributor to the problem, but recently a new concept called moral injury has also become recognized as a significant factor. Today on the podcast, we discuss moral injury and firefighter suicide with Jeff Dill, a licensed clinician and former battalion chief who is the founder the Firefighter Behavioral Health Alliance (3:15). We also talk about the many factors—good and bad—that play a role in the overall mental health of today’s first responders.
Then, on a new Code Corner, Curt Floyd, the technical lead for responders at NFPA, discusses the new consolidated standard NFPA 1030 and the new guidance it gives on professional qualifications for first responder inspectors (36:00).
