Why Your Dry System Leaks More Than You Think

Shawn Mahoney on NFPA 241, Wood-Frame Fires, and the Enforcement Gap

Shawn Mahoney of NFPA's Technical Services team joins Drew for his fourth time on The Fire Protection Podcast, and this one covers a lot of ground before landing on a problem the industry keeps stepping over: construction-site fires. You've seen the headlines. A light wood-frame building goes up mid-construction, and the whole thing is gone, like the Denver complex that took a 238-unit building with it, or the South Park fire in North Carolina that killed two workers. Shawn's point is blunt: we already have the standard to prevent this. It's NFPA 241, the Standard for Safeguarding Construction, Alteration, and Demolition Operations, and it's been around since 1930. It's referenced by NFPA 1, NFPA 101, the IBC, and the IFC. "The biggest issue is people just aren't using it," Shawn says. The code isn't broken. Enforcement is. Drew and Shawn dig into why adoption is so piecemeal, what real enforcement looks like (Boston shuts a site down if the fire prevention program manager isn't there), the legislative push after the North Carolina fire, and what the Fire Prevention Program Manager actually has to do day to day. Before that, they preview the NFPA Conference & Expo in Las Vegas, including Drew's Tuesday session on AI and fire protection, how AI has reshaped the codes world through NFPA LiNK, CASI, and the new Notebooks feature, and why data centers and small nuclear reactors are creating fire-protection problems in towns that have never seen anything like them. Join Drew for Episode 96 for a real conversation about why the standards we already have only matter if someone enforces them. Topics covered: * Inside the NFPA Conference & Expo in Las Vegas * AI in fire protection: NFPA LiNK, CASI, and NFPA Insights * LiNK Notebooks for codes, checklists, and impairment permits * Data centers and small nuclear reactors as emerging fire risks * Light wood-frame construction fires and why they're catastrophic * NFPA 241 and the enforcement gap * The Fire Prevention Program Manager role   TIMESTAMPS * 00:00 – Introduction * 02:27 – Inside the NFPA Conference & Expo * 05:35 – AI in Fire Protection * 07:46 – Data Centers & Small Nuclear Reactors * 09:13 – NFPA LiNK, CASI & NFPA Insights * 12:00 – LiNK Notebooks * 15:21 – NFPA 241: A Standard Since 1930 * 16:50 – Why Wood-Frame Construction Fires Are Catastrophic * 19:07 – Referenced Everywhere, Enforced Almost Nowhere * 20:36 – How Boston Enforces 241 * 25:54 – The Fire Prevention Program Manager Role * 28:33 – Educational Videos & NFPA's YouTube Channels * 30:23 – Conclusion

From Fitter to Founder with Levi Rock of Red Seal Fire Protection

Levi Rock got laid off for three weeks when COVID hit, and it changed how he thought about job security. In 2020 he started Red Seal Fire Protection in Windsor, Ontario, and grew it to 17 employees in five years by keeping it simple: show up when you say you will, turn reports and deficiency quotes around within 48 hours, and get out of the way so customers never have to think about their fire protection. In this episode, Levi joins Drew Slocum to talk about building a service-first fire protection business. They cover the recurring-revenue membership model behind it, why he says no to most new-installation work, how Red Seal uses social media to educate property managers and recruit fitters, and how Inspect Point replaced their PDF forms with consistent, faster reporting. They also get into the gap between NFPA 25 and the Ontario Fire Code, why contractors and AHJs need to communicate more, and why human expertise still beats generic AI on fire code. Episode #95.

Why Your Dry System Leaks More Than You Think

Ray Fremont Jr., president of General Air Products, joins Drew to talk about the air supply side of dry pipe sprinkler systems. General Air Products has been building air compressors for fire sprinkler systems since the 1960s, and the Fremont family has been in the compressed air business since the 1930s. Ray covers how dry system air supply has changed over the last century: plant air compressors and schedule 40 pipe, the shift to thin-wall steel, nitrogen generators, and a newer vapor corrosion inhibitor technology called Vapor Pipe Shield that creates a molecular barrier on the inside of the pipe. They also dig into some real problems: most dry systems leak well beyond what NFPA 25 allows, jurisdictions are a decade behind on code adoption, and air compressor maintenance still gets skipped. Ray previews a new digital monitoring device that tracks compressor cycling and flags system issues before they turn into failures. It's the kind of predictive data the sprinkler side has never had.

The Code Committee Insider: Fire Alarms, CO Detection & What’s Coming Next

Dr. Roger Reiswig, Industry Liaison at Johnson Controls, joins Drew for a conversation spanning nearly 40 years of fire alarm industry experience. Roger started as a Simplex technician in 1986 and now represents JCI across NFPA, UL, FM, and international organizations including the European Alarm Association (Uralarm). Topics include how countries outside the US often adopt NFPA codes faster than US states, the differences between European EN standards and NFPA/UL requirements, Europe's mandatory smoke detector replacement cycles, the new 40-foot ceiling allowance for smoke detectors in NFPA 72, remote and automated inspection technology and its UL listing challenges, how UL and NFPA standards push each other forward, the birth of NFPA 3 and NFPA 4 for integrated testing (now showing up in building codes), Canada's ULC certification model, and the history of carbon monoxide detection moving from NFPA 720 into NFPA 72.   Timestamps: 0:00 - Cold open 0:27 - Episode intro 1:36 - Drew and Roger connect 2:14 - Global adoption of NFPA codes 3:39 - How aggressively other countries adopt new editions 5:03 - Why US states are slow to adopt 7:51 - Roger's career: Simplex technician to JCI liaison 10:15 - European standards (EN) vs NFPA 11:39 - Europe's smoke detector replacement requirements 14:15 - Smoke detector placement at 40-foot ceilings 17:08 - Remote and automated inspection technology 20:34 - UL listing challenges for remote testing 23:45 - Mass notification: UL 864 to UL 2572 24:34 - The 2010 NFPA 72 scope change 26:00 - NFPA 3 and NFPA 4 for integrated testing 29:49 - Canada's ULC standards vs US 32:13 - Carbon monoxide detection in NFPA 72 36:52 - How CO detectors are tested 39:11 - Wrap-up   Learn more about Inspect Point: https://www.inspectpoint.com Request a demo: https://www.inspectpoint.com/get-a-demo LinkedIn: https://www.linkedin.com/company/inspect-point YouTube: https://www.youtube.com/@inspectpoint

Behind the Scenes with IoT Monitoring: What Homeowners Miss About Electrical Fires

Bob Marshall, CEO of Whisker Labs, joins Drew Slocum on Episode 92 to discuss Ting, the IoT sensor that monitors home electrical systems for arcing hazards before they become fires. In this episode: * How Ting takes 30 million electrical measurements per second from a single outlet * The on-device and cloud AI that detects electrical arcing using image recognition * 26,000+ hazards identified (and growing at 30 per day) * Real data from Hurricane Helene, the LA wildfires, and Winter Storm Fern * Why outlets, extension cords, and holiday lights are the most common hazards * How 35+ insurance partners provide Ting to homeowners for free * The 1.3 million sensor network monitoring the entire U.S. utility grid * What this means for the fire protection industry and commercial applications  Bob also shares the personal story behind founding Whisker Labs and how their fire safety team works directly with homeowners and electricians to find and fix problems before they cause fires.
