NASA Deploys Low-Cost Thermal Sensors on Fire Bulldozers

NASA's FireSense project developed low-cost thermal sensors for fire bulldozers that alert operators when heat from nearby flames reaches dangerous levels. The sensors use commercial thermocouple components (same as ovens/kilns) wired to dashboard LEDs, powered by AA batteries. Alabama Forestry Commission tested the first units on wildfires and prescribed burns since September 2025, with operators reporting better situational awareness. The sensors also collect critical data on fire behavior beneath the canopy for researchers.

Based on pilot success, AFC is considering outfitting all dozers in its fleet. Future plans include integrating FireTIRS (Fire Thermal InfraRed Spectrometer) to measure temperature, spread rate, flame length, convection, and gas emissions, plus anemometers and compact cameras for wind/burn severity data.

The take: This is the kind of innovation firefighters actually need - low-cost, field-tested, solves a real problem. NASA isn't building sci-fi gear; they wired a kitchen-grade thermocouple to a dashboard LED and ran out to the hardware store for a missing part mid-install. AFC is now looking at outfitting the rest of the fleet. The fact that it also generates research-grade fire behavior data is the bonus. Other agencies should take notes: you don't need bleeding-edge tech to save lives, just smart application of what already exists.

Federal Firefighter Cancer Registry Pushes Past 49,000 Enrollees

The CDC's National Firefighter Registry for Cancer crossed 49,461 enrolled firefighters as of May 22, with about 2,000 new sign-ups every month. Run by NIOSH, it is now the largest occupational cancer study of any profession in the country. Over 20 percent of enrollees have wildland experience, an exposure group researcher Kenny Fent has called "particularly understudied." The registry was briefly shut down last April during HHS layoffs and brought back online after pressure from the fire service, and it now feeds the federal data behind cancer presumption laws and PPE standards.

Micro Grants (applications requesting $75,000 or less across all programs) streamline the process for smaller departments. State fire training academies are eligible for equipment, PPE, and vehicles. Federal match requirements typically range from 5-20% but waivers are available for small/rural departments and those serving economically disadvantaged communities.

The take: Every firefighter you ride with should be enrolled. Twenty minutes online and your career exposures become part of the dataset that determines whether your widow gets denied on the cancer presumption claim in 2045. The fact that the registry got switched off last year and only came back because firefighters yelled is the whole point: this is ours to protect.

Johns Hopkins Study: Fire Service Leaders More Worried About Health Data Than Firefighters Are

A new peer-reviewed study from Johns Hopkins Bloomberg School of Public Health and the University of Colorado interviewed 65 career firefighters, union reps, department leaders, and national fire service leaders to map out how the field actually feels about sharing occupational health data. The findings: firefighters mostly want their data de-identified, with mental health flagged as the most sensitive category, and most are frustrated when data goes to researchers or chiefs with no clear explanation of what it is for. Department and national leaders held stronger concerns about job-loss risk and data misuse than the firefighters did.

The authors recommend building privacy protections, identifiable-data limits, and plain-language communication into every wearable, app, or CAD-attached health platform departments roll out. The research surveyed firefighters in Maryland and Virginia, plus national-level union, government, and research leaders. It is the first peer-reviewed look at firefighter data privacy preferences during the rise of biometric PPE, exposure-tracking apps, and federal registries like NERIS and the National Firefighter Registry for Cancer.

The take: Every department buying wellness wearables, exposure trackers, or CAD-linked health dashboards in 2026 is about to walk into this fight. The cancer registry, NERIS, and biometric PPE all run on firefighter data, and the people generating that data have specific opinions about who sees what. Mental health data was flagged as the most sensitive category in the study, which is a useful early warning for any chief about to roll out a peer-support platform with built-in analytics. Read the study before you sign the vendor contract, not after.

Berkeley Faces Fire Station Closure in $30M Budget Crisis

Berkeley City Council signaled support for City Manager Paul Buddenhagen's budget plan to close $30 million structural deficit, including potential closure of Fire Station 4 (North Berkeley) and layoffs of 20 full-time employees. Fire Chief David Sprague called the station closure a "nuclear option" that would materially reduce public safety service levels and increase emergency response times. Station 4 was targeted because it handles second-fewest calls citywide and its territory can be absorbed by other stations (unlike the least-busy hillside station on Shasta Road).

The city is pursuing a 0.5% sales tax increase for November 2026 ballot that would raise $9M+ annually - enough to keep the station open and prevent other fire/police/parks cuts. A city-commissioned poll found 52% voter support (within 4.4% margin of error). Even if the tax passes, Berkeley would still cut 130 vacant positions and lay off 20 FTEs. Firefighters union warned the cuts "could put lives at risk by increasing emergency response times, reducing available crews during major incidents, and weakening Berkeley's ability to respond to fires, medical emergencies, wildfires, and disasters."

The take: This is the budget calculus playing out in cities across the country - close a station or ask voters for more taxes. Berkeley's strategy is risky: they're approving a budget that includes the closure, then hoping a ballot measure saves it six months later. That's gambling with response times. The fact that Station 4 was picked because its area "can be absorbed" doesn't mean response times won't spike - it just means there's geographic coverage, not adequate coverage. Watch how voters respond to the sales tax; it'll set the tone for other California cities facing similar deficits.

NERIS Crosses 10 Million Incident Reports as NFIRS Officially Retires

The National Emergency Response Information System (NERIS) has logged over 10 million incident reports since launch, marking the successful transition from the retired National Fire Incident Reporting System (NFIRS). NFIRS officially sunset on January 31, 2026. NERIS is a cloud-based, all-hazards incident reporting platform developed by UL FSRI that supports near real-time submissions, API integrations, and more complete incident data than its predecessor.

The platform reached 1 million reports in December 2025 and has rapidly scaled as thousands of departments complete the transition. States like Oklahoma - where electronic reporting participation plateaued at 50% for 15 years - are seeing participation jumpstart at the state level. NERIS includes a new dashboard that allows departments to visualize and analyze their own data. The system integrates with third-party records management software from vendors like ImageTrend, ESO, and First Due.

The take: NERIS hitting 10 million reports five months after NFIRS died is proof the transition didn't crater like some departments feared. The fact that Oklahoma - stuck at 50% adoption for 15 years - is finally moving tells you the old system was the problem, not firefighter buy-in. Real-time data submission and API integration mean this isn't just better reporting, it's the foundation for predictive analytics, resource optimization, and grant justification. Departments still on paper or legacy software need to get onboard - NERIS is the new baseline, and being able to show your incident trends in a dashboard is table stakes for budget conversations.

Cary, NC Deploys East Coast's First Electric Fire Truck

Cary, North Carolina, deployed the East Coast's first electric fire apparatus - a Pierce Volterra electric pumper - as part of a decade-long fleet electrification strategy. The deployment followed years of light-duty EV experience and demonstrates how municipalities can scale into heavy-duty, mission-critical applications. Cary firefighters reported immediate benefits: zero tailpipe emissions in already-hazardous work environments, quieter cab allowing better crew coordination, more temperate interior, and improved working conditions.

The truck's batteries are positioned between cab and pump house (below the apparatus center of gravity) for zero impact on handling/performance while preserving compartment space and body configuration. Cary worked closely with Pierce, Duke Energy, and town leadership to coordinate charging infrastructure, utility load planning, and operational integration. Environmental Defense Fund (EDF) documented the deployment in a video case study.

The take: This is what smart fleet transition looks like - Cary didn't jump straight to electric ladder trucks; they spent a decade on light-duty EVs, learned the infrastructure requirements, built utility partnerships, then took the leap on heavy-duty. The firefighter feedback is what matters: better air quality, quieter cabs, and no compromise on performance. For departments watching from the sidelines, the lesson is clear - electrification isn't theoretical anymore, it's operational. The limiting factor isn't the truck; it's charging infrastructure and utility coordination. Start those conversations now, or you'll be five years behind when your diesel fleet ages out.

FSRI Fire Safety Academy

The Fire Safety Research Institute (part of UL Research Institutes) runs a free online training platform that turns the FSRI research catalog into structured, self-paced courses any firefighter can take from a phone. Topics include coordinated fire attack, search and vent, flow path control, residential structure fires, modern fuel load behavior, and tactical considerations on solar arrays and lithium-ion batteries. Every course is grounded in the live burn research FSRI has run with departments like FDNY, ATF, and the Chicago Fire Department over the last decade.

If you have ever read a UL FSRI study and wished there was a structured way to walk a probie through it, this is that. Department admins can pull completion records for ISO and accreditation, and the courses meet several state continuing education requirements. Worth bookmarking, then putting a 30-minute weekly block on the calendar.

Cost: Free (membership available for sprinkler contractors)
For: Fire departments, fire marshals, community risk reduction coordinators

What We're Watching

US Wildland Fire Service stand-up. Brian Fennessy, former Orange County Fire Authority chief, is now the inaugural chief of the Department of the Interior's new US Wildland Fire Service. The agency is supposed to consolidate federal wildland response that was scattered across BLM, BIA, USFWS, and NPS. Watch for the first organizational chart, the first hiring authority, and whether the Forest Service stays separate or eventually rolls in.

Gold Helmet department milestones. CDC's cancer registry awards Gold Helmet status to departments where 50 percent or 300 firefighters enroll. Orange County Fire Authority is one of two California departments to hit it. Watching which mid-size departments cross the threshold next, and whether IAFC or state chiefs associations build enrollment into accreditation criteria.

Electric apparatus charging gaps. Cary is one US East Coast department running an electric pumper. The bigger question is municipal charging infrastructure: a Class A pumper draws far more than a fleet of patrol cars or transit buses, and many fire stations were wired in the 1970s. Watching which utilities and which states fund station electrical upgrades before the next 10 departments order their first EV apparatus.
