SWANA and Fire Rover launch lithium-ion battery safety resource hub

Fire Rover collaboration with SWANA on battery safety webpage

The Solid Waste Association of North America (SWANA) has partnered with Fire Rover to launch a webpage focused on battery safety and preventing fires linked to lithium-ion batteries disposed of in waste and recycling streams, as reported by Waste Today.

SWANA said lithium-ion batteries are increasingly common in everyday products and can end up in household trash and recycling bins.

It said batteries can ignite fires in collection vehicles, processing facilities and landfills.

The webpage is described as a resource for fire safety and data collection, with waste and resource management professionals encouraged to report fires that occurred at facilities or in vehicles.

It includes an anonymous reporting feature with fields for incident details, the cause if known and photos.

Webpage tools and reporting fields

Waste Today said the webpage includes a searchable tool to help users find battery drop-off and recycling locations near them.

It also includes educational content and resources focused on battery safety and fire prevention.

The webpage also includes information describing the roles of communities and industry professionals in reducing battery-related fire risks.

SWANA said it will use the reported data and examples to support outreach and advocacy efforts for battery safety.

SWANA CEO Amy Lestition Burke said: “Battery safety has been a top priority for SWANA,

“This new webpage is our latest tool to support our members and the public with preventing battery-related fires.

“We have been hearing from our SWANA Lithium-Ion Battery Workgroup about the need for a centralized database to report battery fires.

“Fire Rover, a corporate partner of SWANA, worked with us to make this a reality.

“We appreciate this productive partnership with Fire Rover.”

Ryan Fogelman of Fire Rover said: “This new webpage reflects the shared mission of SWANA and Fire Rover to protect workers, facilities and the public from the growing risk of fires linked to lithium-ion batteries.

“Preventing battery-caused fires requires education, shared responsibility and access to practical solutions.”

The organisations said the broader partnership also covers data sharing, education and joint programming linked to lithium-ion battery fire hazards.

A practical guide to lithium-ion battery risk at MRFs with Ryan Fogelman

By Ryan Fogelman, Fire Protection Consultant, Fire Rover

The waste and recycling industry has reached a critical inflection point when it comes to lithium-ion battery fires.

For years, operators, firefighters, insurers and municipalities have grappled with a problem that continues to grow faster than our collective ability to manage it.

That’s why the “Guide for Developing Lithium-Ion Battery Management Practices at Materials Recovery Facilities,” jointly published by the National Waste & Recycling Association (NWRA), the Recycled Materials Association (ReMA) and the Solid Waste Association of North America (SWANA), represents an important and timely step forward.

What the guide recognises

The guide acknowledges a reality many of us in fire protection have been documenting for nearly a decade.

Lithium-ion batteries, particularly those embedded in everyday consumer products, are now the leading cause of fires at waste and recycling facilities across North America.

From phones and power tools to e-bikes and disposable vapes, these batteries are entering waste and recycling streams in unprecedented volumes, often damaged, hidden and highly unstable.

I’m humbled by the recognition in the guide, particularly in connection with the fire incident data I’ve been compiling and publishing annually since 2016.

What 2025 data shows

If you read my reports, you already know that this year was the worst on record for publicly reported fires since I began consolidating and sharing the data in 2016.

We finished the year with 448 publicly reported waste and recycling facility fires in the U.S. and Canada.

That total is more than last year’s record of 430 fire incidents.

That total is nearly 25% above the annual average of 360 fire incidents.

While data alone doesn’t solve the problem, it plays a critical role in validating what operators and first responders experience on the frontlines every day.

The guide’s inclusion of this information signals an important shift.

Industry associations are now aligning around the fact that lithium-ion battery fires aren’t isolated events or operator failures.

They are a systemic risk tied to product design, consumer behavior and inadequate end-of-life pathways.

What the guide recommends for MRFs

The guide doesn’t pretend there is a single solution, nor does it place unrealistic expectations on facility operators.

Instead, it focuses on risk reduction, not risk elimination.

The more layers of protection you have, the lower the chance that fire can slip through the cracks and grow out of control.

As the guidance states, operators should focus on the following key areas.

  • Early identification and isolation practices for suspect batteries.
  • Employee training that emphasises recognition and response rather than blame.
  • Safe storage and handling protocols designed to limit collateral damage and contamination.
  • Emergency response planning that accounts for the unique behavior of lithium-ion fires.
  • Public education and customer messaging that acknowledges that upstream behavior matters.

Why frontline expectations need to change

The overlying fact remains that our waste and recycling employees should not be the front-line response team unless they are fully and properly trained and equipped with the right tool belt for the job.

This is why our Fire Rover solution is so effective.

It provides the earliest confirmed detection possible, and our agents manage the first six to 10 minutes of an incident, bringing order to the chaos and providing critical communications to operators and fire professionals.

The vape effect in real-world operations

In reality, waste and recycling facilities are being asked to manage a fire risk created largely outside their control.

Disposable vaping devices are a prime example.

These products combine lithium-ion batteries, thin casings and widespread improper disposal, making them uniquely dangerous once they enter processing equipment.

Data drawn from publicly reported fires at waste and recycling facilities consistently shows a troubling upward trend that I’ve identified as the vape effect.

In a nutshell, we’ve seen reported incidents increase about 26% from 2022 to 2025 compared to the average from 2016 to 2021.

I believe this vape effect is driven largely by the lack of safe, convenient drop-off locations for post-consumer electronics such as vaping devices.

Notably, in the US and Canada, this increase would be much higher if a significant number of facilities weren’t protected by Fire Rover.

What the guide signals for the sector

The release of this guide by the NWRA, the ReMA and the SWANA sends a clear message.

The industry is no longer treating lithium-ion battery fires as an operational nuisance.

It’s recognising them as a defining safety challenge of our time, and these associations are now being called on to create a proven and practical strategy for their members to learn from and best practices to follow.

From my perspective, this guide is best viewed as a foundation, not a finish line.

It equips facilities with tools they need today while reinforcing the case for broader systemic change tomorrow.

Fire risk in the waste and recycling sector will not be solved by education, technology, regulation or operators alone.

It will be solved when data, policy, product design and on-the-ground fire protection strategies finally move in the same direction.

This guide is an important step toward that alignment, and one the industry has needed for a long time.

What needs to happen next

The guide rightly calls for collaboration, but the next phase must include direct accountability and participation from battery, consumer electronics and tobacco manufacturers to help fund solutions.

Product design changes, battery removability, takeback programs and funding for public collection infrastructure aren’t optional if we expect meaningful reductions in fire incidents.

Fire Rover performance update

At Fire Rover, we continue to do our part.

We finished the year protecting more than 850 facilities.

Over the past 10 years, our system has only been overpowered twice while delivering results that were previously unheard of in the fire protection space.

The reality is that many suppliers are talking a lot and selling solutions, whether DIY approaches or other technologies, that may appear to address the problem on the surface.

Buyer beware.

There’s a reason Fire Rover is the only FM Approved smart monitor in the world, and that comes from experience, not arrogance.

Where Fire Rover started for me

I’m blessed that in 2015, Brad Gladstone and his partners, Jeremy and Pete, invented Fire Rover and that I was able to witness the first box demonstrated in the back of a scrap metal yard in my hometown of Detroit.

As with any company starting out, some people believed in us and some didn’t, but we’ve since proved to our loyal customers, insurance partners and thousands of fire professionals that our solution does what we said it would do.

In the early years, some assumed our solution was off the shelf and their best route was to try and build their own in-house solution.

Even if you can, that doesn’t mean you should.

Cost, insurance and real-world reliability

The cost of our system is largely offset by insurance savings as it helps mitigate the risk of a major or catastrophic loss by more than 99%.

For most of our systems, the cost is roughly equivalent to half of a full-time employee.

Insurance companies have been learning the hard way that all solutions are not created equal.

Many of these systems have been turned off, especially during the day, or pulled out leaving a trail of wasted dollars, time and effort.

I’ve seen many systems look pretty in the brochure but fail when it comes to real-world deployment.

Our systems are battle-tested, and we install them, maintain them and warranty all the components.

We’ve never had a false discharge, and our systems use an average of less than 500 gallons of suppressing agent or water per event.

Conclusion

It feels like tax season again.

Another year is complete, and another set of data is ready to be added to my annual report.

Last year’s report, “We Are at War: The 8th Annual Waste & Recycling Facility Fires Report in the US & CAN,” is being updated to include 2025 data and analysis.

I’m calling this report, “Fortifying the Front Lines.”

Across the U.S., Canada, France, Australia and now the United Kingdom and New Zealand, operators are making the investments needed to get a handle on the battery-related fire risk, a challenge sure to haunt us for many years to come.

To be clear, this investment is a layered approach that combines public education, policies to expand local and safe battery drop-off locations, efforts to make batteries removable from devices, operational best practices and continued investment in technologies.

Speaking of public education, I’m proud to announce that we’re making progress on a children’s book about lithium-ion battery safety, which we’re currently writing with the help of Dalan Zartman of the Energy Security Agency (ESA).

The book will include a children’s story and parent and teacher facts provided by the SWANA, the NWRA, the ESA and several other organisations.

Individuals and organisations can make a donation to provide copies of this book to classrooms across the U.S. and Canada through The Recycling Society.

If you’re interested in sponsoring a school or school district, feel free to reach out, and I will point you in the right direction.

As Fire Rover heads into its 11th year, the fire problem continues to grow.

Despite this, I truly believe we’re beginning to get a handle on this massive challenge that affects waste and recycling operators and the public at large.

I hope to have better news to share over the next 12 months.

Our waste and recycling operators perform a critical service for society, and we cannot afford for this risk to continue without an all hands on deck approach from all sides.

Why the vape effect matters: A plea to the tobacco industry from Fire Rover’s Ryan Fogelman

Vapes, weather and waste fire trends, by Ryan Fogelman

As we approach the end of the year, the waste and recycling industry is on track to reach a record number of publicly reported facility fire incidents in the US and Canada.

Much of the increase is driven by improperly discarded lithium ion batteries, including the rapid rise of disposable vapes that continue to enter waste streams in huge volumes.

In this month’s report, I share November’s fire data, explain the scale of the vape effect and outline the key points from my open letter to the tobacco industry urging collaboration on solutions the waste and recycling sector cannot deliver alone.

November 2025 fire data

We started 2025 on the wrong note by setting concerning records that marked the worst start to a year since I began tracking publicly reported waste and recycling facility fires in 2016.

July’s 56 reported incidents were the highest number ever recorded for that month and the highest single month total in the past decade.

August followed with 49 incidents and September reached 45.

In October there were 48 publicly reported incidents, outpacing the previous record year of 2022 by ten incidents at that stage in the calendar.

In November we had 27 fires, which was not a record but was only one incident below our highest November in 2020.

Scrap metal recycling yards fell behind waste, paper and plastic facilities with nine incidents, while waste, paper and plastic facilities recorded 13.

Organics management, rubber, construction and demolition and chemical or hazmat facilities each recorded one incident.

Year to date, scrap metal yard fires are still around 30 percent of all publicly reported incidents, which is in line with the long term pattern.

Based on current totals, I would be shocked if we did not end 2025 with the highest number of fire events ever recorded.

Even applying a simple December average would put the total at more than 440 incidents.

Unless December is unusually low, 2025 will be the worst year for publicly reported incidents since I began tracking in 2016.

What Fire Rover data shows

Fire Rover is seeing similar incident patterns.

Through September we responded to more than 3,000 confirmed fire events at client facilities and successfully responded to and suppressed 383 using our patented FM approved smart monitoring solution.

Like the publicly reported data, our incident volumes slowed entering the last two months of the year.

Once the year closes, I will release our full performance dashboard for 2022 to 2025.

At RCon I joined Alex Finkelstein of Teledyne FLIR for a discussion on how Fire Rover’s solution helps protect facilities from lithium ion battery hazards in critical infrastructure.

We took a deep dive into early detection and remote operated smart monitoring solutions and how our partnership led to the first FM approved remote operated fire protection system.

Although lithium ion batteries are a major contributor to increased incidents, I have also found that increased heat and dryness across the US and Canada remain significant factors for waste and recycling operations.

I will analyse weather correlations in my 2025 annual report, publishing in March 2026.

The vape effect

In my research I have identified what I call the vape effect.

The US and Canada have seen a 26 percent increase in the average number of facility fire events from 2022 to 2025 compared with the previous six years.

That figure does not include the 7 to 10 percent of facilities protected by Fire Rover, but if those were included I believe the increase would be closer to 40 percent.

The rapid shift from traditional cigarettes to vapes is a major contributor.

There were approximately 6 million new vape users from 2022 to 2024.

Many vapes are marketed as daily disposables and contain lithium ion batteries that must be handled as hazardous products.

We are lacking safe and convenient drop off locations, which means these devices often end up in waste streams where they can be crushed or punctured.

My estimate of 48 million vapes per week entering waste and recycling streams is likely conservative.

Biffa sorted 840,000 vapes in four months at only four locations, averaging 7,000 per day.

Extrapolated across an estimated 10,000 waste and recycling facilities in the US, the total would exceed 70 million vapes improperly discarded every day.

Regardless of whether the real number is 48 million per week or far higher, the scale is staggering.

Battery manufacturers are contributing through voluntary programmes and extended producer responsibility legislation, but the current level of funding and infrastructure is not enough.

Tobacco manufacturers need a seat at the table to address the device design issues that drive so many of these problems.

What I said in my open letter to the tobacco industry

In November I wrote an open letter to executives in the American tobacco industry addressing the growing number of facility fires linked to discarded vaping devices.

In the letter I explained that my data highlights a clear and concerning rise in fires linked to vapes and that this trend poses safety risks to workers and the public as well as financial and environmental harm.

I made it clear that I was not blaming the tobacco industry or suggesting wrongdoing.

Instead I asked for collaboration on reasonable and achievable solutions that can reduce needless losses and injuries.

I explained that the waste and recycling industry cannot solve this problem alone and that tobacco manufacturers can play an important role in several areas.

I outlined the need for public awareness campaigns to inform consumers about proper disposal.

I called for product design changes to allow easy removal of batteries so that they can be safely recycled instead of entering waste streams.

I highlighted the importance of convenient local drop off locations for used vapes.

I emphasised the value of joint research and data sharing to deepen understanding of the problem and support practical solutions.

I explained that lithium ion batteries in vapes are causing billions of devices to enter waste facilities and that major fires linked to these batteries result in an estimated 1.2 billion dollars in damages annually.

I stressed that without the involvement of tobacco manufacturers, the problem will continue to escalate.

I closed by expressing confidence that collaboration between our industries can advance safety and sustainability.

Partnerships and next steps

I am pleased to announce a new partnership between Fire Rover and the Solid Waste Association of North America.

The goal is to provide resources that help waste operators understand and mitigate risks by expanding access to safe and convenient disposal in more communities.

We are also launching the first Anonymous Incident Database for reporting these hazards.

When combined with videos shared by customers, this database will be valuable to insurers, fire professionals and facility operators working to mitigate risk.

As we head into 2026, education, operational best practices and technologies like Fire Rover are working to reduce the risks of major or catastrophic losses across critical waste and recycling infrastructure.

Buyers should be careful.

Early detection and automated solutions are not Fire Rover.

There is no substitute for trained human operators and a comprehensive fire protection strategy that works every hour of every day.

Approval in action: What FM Approval means for Fire Rover’s suppression systems

Ryan Fogelman, Fire Protection Consultant, explains what FM Approval means for Fire Rover‘s system and the company’s role in managing growing global risks

Fire Rover has become the first company to obtain an FM Approvals listing for a remotely-operated fire-suppression monitor.

Its proprietary technology, which has been deployed in more than 750 systems, is now certified under six separate FM standards.

Ryan Fogelman, Fire Protection Consultant at Fire Rover, sat down with IFSJ Editor Iain Hoey to explain what the certificate means, how the technology works and where early-stage suppression is most urgently needed – especially as lithium-ion batteries drive a steady rise in waste-handling fires.

What does FM Approval mean for your newly certified Continuous Flow Primary System?

Our cameras, detectors, control panels and monitors have carried individual UL, ETL and FM component listings for years, but each installer still had to prove the assembled package satisfied code intent.

The new FM Approvals report treats hardware, software, water delivery and the monitoring service as one tested product.

That simplifies design, eliminates variances and, most importantly, lets insurers quantify the installation as a proven risk-reduction measure.

FM Global writes the standards used in chemical warehouses, aircraft hangars, recycling yards, waste-transfer stations and bulk-storage sites – the very occupancies we protect.

Because FM Global also insures many of those buildings, the listing tells underwriters they can credit the system when setting deductibles or loss-prevention requirements.

The certificate therefore translates directly into lower property-loss expectancy, faster project sign-off and, for owners, a single document that satisfies both code officials and insurers in one review step.

Just as critically, the listing puts Fire Rover on the same footing as long-established sprinkler technologies in engineering guides and specification libraries.

Engineers can now reference a recognised FM datasheet instead of drafting a bespoke narrative, which should accelerate adoption in design-build tenders and public-procurement bids where deviations from catalogued products are discouraged.

Which FM standards did the system pass, and why is each significant?

The Fire Rover system has achieved FM Approvals certification by meeting six rigorous standards:

  • FM 1421 checks monitor body strength, flow stability and corrosion resistance
  • FM 5511 verifies nozzle pattern and volume at every elevation and azimuth
  • FM 3810 subjects the control cabinet to electromagnetic, surge, vibration and temperature cycling
  • FM 3010 & 3011 confirm alarm signals meet NFPA 72 and that the central station meets redundancy and training rules
  • FM 3260 evaluates infrared and optical flame detectors for speed, sunlight immunity and calibration drift

After lab work, FM auditors visit our plant, pull units from production, review calibration logs,trace parts back to suppliers.

Spot-checking continues for the life of the certificate, so the thousandth monitor shipped next year must match the first that went through the burn rooms.

That continuous scrutiny builds confidence not only for regulators but also for facilities that cannot tolerate downtime caused by defective suppression gear.

What components form Fire Rover, and how does detection differ from ceiling sprinklers?

Dual-spectrum flame detectors and radiometric thermal cameras provide detection.

Because the camera “sees” absolute temperature, it spots a hot lithium-ion cell even through smoke or darkness.

Ceiling sprinklers, by contrast, wait for heat to rise ten metres or more, which can take fifteen minutes.

Fire Rover generally intervenes when heat release is still 100–200 kW; a ceiling system often does not open until the flame has grown past several megawatts and engulfed roof steel.

An operator at an FM- and UL-listed central station then aims a2.5-inch electrically driven monitor onto the exact coordinate.

The nozzle delivers 150–500 gpm, yet a many incidents require less than 500 gallons – less than five per cent of the water released by a thirty-head sprinkler activation.

Designers can specify Fire Rover alone or use it as a fast-attack layer in front of sprinklers; in mixed systems our Fire Rover is able to identify and suppress the system long before ceiling heads fuse, demonstrating how early intervention shrinks loss size and prevents sprinkler-related water damage.

How do remote operators verify alarms and decide precisely when to release water?

Each site streams visual and thermal video to two geo-redundant monitoring centres.

If a camera spots a temperature spike or persistent smoke, the event jumps to the top of the operator’s console.

The operator compares thermal and visible feeds, filters nuisance triggers – such as hot exhaust manifolds or sunlight reflections – and, if a fire is confirmed, alerts the local brigade, energises the pump, swings the monitor and opens the valve.

Cross-hair overlays show real-time temperatures, letting the operator throttle flow or shift aim the moment the hotspot cools.

Because a trained human remains in the loop, the system has never recorded an accidental spray in more than 3,000 field incidents.

The same person can also warn on-site staff via loudhailer, wait for personnel to clear the area, and protect nearby assets by drawing a water curtain.

A digital report – time-stamped video, water usage, detector data and actions – arrives in the client’s inbox following the event, giving safety managers clear evidence for regulators, insurers and internal audits.

In practical terms, how does FM listing speed insurance and regulatory approval?

Early projects required a means-and-methods variance because the system was not yet listed for fixed fire protection.

We submitted computational fluid-flow modelling, live-burn data and field videos; most fire marshals approved, but the paperwork cycle could stretch to months.

With the FM listing the variance disappears: the designer now references the published data sheet, and the plan reviewer signs off during the ordinary permit window.

Insurers respond similarly.

Several carriers – including ones that do not write FM policies – already credit the system as a primary suppression method.

Clients in the waste and recycling sector have seen deductibles fall by double digits, while property owners rehabbing older warehouses report that a Fire Rover line item can replace expensive roof-level mains.

Across a dozen U.S.

states the listing has trimmed four to six weeks from construction schedules, allowing earlier occupancy and revenue.

Beyond quicker paperwork, the listing streamlines site commissioning.

FM requires our technicians to witness spray tests, detector alignment and communication checks before tagging the system operational.

That structured handover gives owners a clear maintenance baseline and insurers a formal record, reducing follow-up queries that often delay policy issuance.

Has certification helped you deploy in Canada, France, Australia and the United Kingdom?

Yes.

Canada follows NFPA codes closely, so an FM listing transfers almost one-to-one.

UK warehouse owners favour detector-led strategies under BS 5839, making a solution that both detects and acts immediately attractive.

France’s APSAD rules demand third-party listings; the FM report satisfies that requirement and its water-usage data aligns with French environmental discharge limits.

Australia’s water authorities are stringent on runoff, so the low-gallonage figures help there.

In every case the FM certificate answers the first regulatory question before it is asked.

Operationally, the remote-monitoring model also suits multinational owners who standardize operations.

A company with sites on three continents can have consistent operating and fire response procedures across facilities.

 The facilities can all be monitored at one monitoring hub, apply uniform response rules and archive footage in a common cloud platform.

That consistency improves compliance audits and simplifies insurance negotiations, because the underwriter can evaluate one documented process rather than a patchwork of local systems.

Why are lithium-ion batteries and disposable vapes triggering so many waste-facility fires?

Crushing a lithium-ion cell pierces its separator; the electrodes short, temperature soars beyond 500 °C and flammable gas vents like a blowtorch.

The flare may last only seconds, yet it lands in a pile of paper, cardboard, dried organics or plastic wrap.

Within a minute the pile surface becomes a rolling fire front, fed by its own draft.

Because the ignition sits several layers deep, sprinkler water struggles to penetrate, and firefighters must pull the pile apart with loaders while breathing dense smoke.

Disposable vapes compound the problem because their thin casings rupture easily under the pressure inside compaction truck or under a loader tire.

Video from client sites shows a glowing core hidden under thirty centimetres of refuse, invisible to line-of-sight security staff but obvious on a thermal camera.

Immediate pinpoint suppression avoids the need to evacuate workers, shut conveyors, ventilate buildings or, in extreme cases, flood a bunker and pump out contaminated water – a shutdown that can idle a plant for days.

Which industries stand to benefit next, and where is protection still consistently overlooked?

Airfields, chemical plants and fuel depots must retire PFAS-based foam deluge systems.

Fire Rover already handles fires with water, but once the alternate agents complete their own listings the same monitor can deliver fluorine-free foam, wetting agents or encapsulating gels directly onto the hazard – without flooding an entire hangar floor or polluting storm drains.

That targeted, on-demand delivery meets new environmental regulations while maintaining – or often improving – fire-control performance.

On the overlooked side, outdoor waste-wood yards and biomass-fuel piles often rely on truck-mounted hoses alone.

A mast-mounted camera paired with a remotely-operated monitor can cover several hectares for a fraction of the cost of buried mains and hydrants.

The same applies to photovoltaic farms, where an overheated combiner box can start a grass fire kilometres from the nearest hydrant, and to scrap-metal bays where magnesium shavings can ignite under sunlight.

Wherever ignition hides beneath bulky stockpiles, a steerable monitor proves its worth.

Fire Rover expects to manage more than 400 suppression events across its client base in 2025.

Each early knock-down means less smoke, lower repair bills and minimal business interruption – benefits now quantified in a single FM Approvals certificate and deliverable worldwide through an expanding network of virtual firefighters.

Protecting high bay and canopy structures from fires

By Ryan Fogelman, J.D., MBA, vice president of strategic partnerships for Fire Rover and James “Andy” Lynch, MSc, CEO of Fire Solutions Group

High bay and canopy structures pose unique challenges when it comes to fire protection.

These expansive spaces, often found in industrial settings, warehouses and outdoor canopies, require specialised fire suppression systems that can quickly and effectively detect and combat fires.

Traditional methods, such as sprinklers and beam detectors, face limitations in these environments, making it crucial to explore alternative solutions to properly protect these spaces.

Recognising this, we developed the patented Fire Rover Automatic Water Cannon (AWC), a fire protection technology designed to provide rapid detection, visual verification and targeted suppression, thereby reducing nuisance alarms and ensuring enhanced safety measures.

Challenges of fire protection in high bay and canopy structures

High bay and canopy structures are characterised by their towering ceilings, which can significantly delay the activation of conventional fire detection and suppression systems.

Sprinklers, for instance, rely on heat detection to trigger water release.

Still, the height of these ceilings often means the fire has significantly progressed by the time the sprinklers activate.

This delay can result in extensive damage and increased risk to personnel safety.

The activation time for a fire sprinkler in a high bay is significantly longer compared to the activation time for an optical flame detector (OFD).

OFDs use line-of-site detection methods and are tested to FM standards, typically at 100 feet with a small pan fire.

The fire size at detection for the OFDs is between 100 and 250 kilowatts (kW), while the fire size at detection for the overhead sprinkler in a high bay require the fire to grow to be over 40 times larger.

Picture a small campfire compared to a very large bonfire.

Moreover, in open-air environments like tall canopies, weather conditions such as wind pose additional complications.

The buoyant plume generated by a fire can be easily dispersed by wind, rendering traditional sprinkler systems ineffective.

Even moderate wind speeds can push the plume entirely out of the structure, activating the wrong sprinkler heads or failing to suppress the fire altogether.

Modelling sprinkler activation in windy conditions

For a recent project, modelling of the sprinkler activation of a high bay open structure was conducted using the National Institute of Standards and Technology’s Fire Dynamics Simulator (FDS), an open-source computational fluid dynamics package.

FDS utilises Large Eddy Simulation (LES) numerical solution approaches to model the dispersion of gases, specifically low-speed, thermally driven flows like those typically found in fire scenarios.

A Cartesian grid system is applied over which the solutions for thermal plume concentration with time can be solved.

Eight scenarios were modelled with varying fire sizes and structure openings.

A simple building mock-up was simulated to evaluate wind effects on a smoke plume in an open-walled building.

Four scenarios used two heat release rates (1 MW and 5 MW) and two rollup door configurations (one door and four doors).

The fire source was in the centre of the processing pit.

Wind was set at 14.5 mph entering the building’s open side and exiting through the rollup door(s), representing the average wind speed and prevailing direction in the area, per the National Oceanic and Atmospheric Administration.

The simulations used a coarse grid with a cell size of approximately 1.6 feet for a computational domain of 1,416,960 total grid cells and ran for at least 20 minutes.

The domain included an array of sprinklers above the fire with 10-foot spacing, an activation temperature of 135 degrees Fahrenheit, and a relative thermal index of 130.

The simulations varied fire size, door configuration, and wind speed.

Sprinkler activation occurred in all simulations without wind (0 mph), but only in one of the four simulations with wind.

The modelling was limited to steady-state fires and one wind speed and direction.

Despite these limitations, the modelling shows sprinkler activation can be compromised under average wind conditions.

This results in extremely fast sprinkler activation times.

In a similar scenario with the same door and fire scenario but incorporating an average wind condition, despite the extreme thermal condition, the wind can deflect the plume.

This effect would be even greater if a fire growth rate was incorporated into the model rather than the large steady state fire.

Images taken of scenario S2W-5MW, demonstrating the wind flow and smoke condition, respectively.

In this scenario, four doors are open, a 5 MW fire is present and a 14 mph wind condition is imposed on the structure.

It was seen that the wind is directed though the building, deflecting the plume and carrying the heat out of the structure.

Advantages of the Automatic Water Cannon

The Automatic Water Cannon (AWC) is ideal for addressing the challenges posed by high bay and canopy structures.

This state-of-the-art system integrates advanced technology to address the limitations of traditional fire protection methods, providing efficiency and effectiveness.

The AWC utilises thermal detection and flame detection to swiftly identify fire incidents within high bay and canopy environments.

This rapid detection ensures firefighting measures are initiated at the earliest possible stage, minimising the spread of flames and reducing the potential for extensive damage.

Once a fire is detected, the AWC deploys targeted suppression via a remotely controlled monitor, delivering water, foam or listed water additive agents directly to the source of the fire.

This targeted approach ensures maximum effectiveness in extinguishing flames while minimising water usage and collateral damage.

An FM Global report from April 2020 entitled “Reducing Water Demands with Innovative Fire Protection Solutions” showed that AWCs like Fire Rover reduced the water demand by up to 92% when compared to traditional sprinkler systems.

By integrating visual verification capabilities, the AWC distinguishes between actual fire events and false alarms, allowing for prompt and accurate response by firefighting personnel.

This not only enhances overall safety but also reduces operational disruptions and maintenance costs associated with false-alarm incidents.

This is done utilising certified UL Central Stations for monitoring, alarm verification, targeting and suppression activation.

High bay and canopy structures present unique challenges for fire protection, necessitating specialised solutions that can overcome the limitations of traditional methods.

The AWC represents the latest innovation in this regard, offering rapid detection, targeted suppression and visual verification capabilities specifically tailored for these environments.

With its ability to overcome the delays inherent in traditional fire protection systems and mitigate the impact of external factors such as wind, the AWC ensures enhanced safety and peace of mind for personnel operating within high bay and canopy structures.

By investing in advanced technologies like the AWC, organisations can effectively safeguard their assets, personnel and operations against the threat of fire, ensuring uninterrupted productivity and business continuity.
