Fire doorset testing: Why integrated fire resistance and smoke leakage testing matters

Peter Barker of Element Materials Technology explains how integrated fire doorset testing helps manufacturers demonstrate fire resistance, smoke leakage performance and prepare for future EN classification requirements

Fire-resisting doorsets play an important role in compartmentation, helping to limit the spread of fire and smoke throughout a building. Fire resistance has traditionally been perceived as the primary performance characteristic for fire doors, but smoke control is coming into sharper focus when assessing how a doorset performs as a complete assembly.

The planned withdrawal of BS 476 classifications from Approved Document B in September 2029 and adoption of EN-based classification is prompting manufacturers to review how fire and smoke performance is evidenced and classified.

For many manufacturers, that means taking a more joined-up approach to testing, combining fire resistance and smoke leakage programmes to build a clearer picture of overall doorset performance.

Why fire doorset testing is changing

Smoke leakage testing has traditionally focused on sealing systems fitted to the head and jambs of a doorset.

While that approach remains aligned with the current regulatory guidance for smoke control doors, there is now greater attention on understanding the performance of the complete assembly, including how smoke may pass through gaps at the threshold.

More recent guidance, such as BS 8214:2026 has encouraged wider consideration of threshold sealing and the contribution that the bottom gap can make to smoke leakage.

This reflects a broader move towards assessing the complete doorset rather than individual components and ensuring performance clearly links to realworld applications.

Smoke leakage testing and complete doorset performance

Many organisations still approach smoke leakage testing and fire resistance testing through separate programmes. There can be good reasons for working in this way. Product development rarely follows a straight line and designs can evolve.

However, the risk of working in this way is that important design details may be missed that need to be evaluated for both fire and smoke performance characteristics.

The result is that when smoke leakage testing has been carried out on one design and fire resistance testing on another, additional work may be required to establish how those results apply to the final doorset being offered to the market.

The process can become even more complicated when multiple product variations, sizes or hardware options are involved. Manufacturers may find themselves managing several test reports, assessments and supporting documents to demonstrate that a doorset can deliver both fire resistance and smoke control performance.

Benefits of integrated fire doorset testing

Planning smoke leakage and fire resistance testing together in a coordinated programme reduces duplication, testing schedules and project management activities. It can also help manufacturers build a more coherent technical package while reducing the risk of gaps emerging later in the process.

This becomes particularly valuable when results are intended to support extended field of application reports and classifications using the EN 13501-2 framework for doorsets. Integrated programmes can also provide greater confidence when supporting future product developments, particularly where manufacturers plan to introduce additional sizes, hardware arrangements or design variations.

Integrated testing at Warringtonfire Birchwood

Demand for more joined-up testing programmes is one of the reasons Element has expanded its smoke leakage testing capability at the Warringtonfire Birchwood facility. The facility forms part of Element’s £24 million investment in fire testing infrastructure and was opened in January 2025 to support growing demand for construction product testing.

The site includes an indicative furnace for small-scale rapid testing, as well as two horizontal furnaces, two vertical furnaces and 18 preparation bays including confidentiality shields, providing capacity to support a broad range of testing requirements.

Dedicated witnessing facilities and meeting spaces also allow manufacturers to work closely with technical specialists throughout a programme. It also includes a solution that enables both fire resistance and smoke leakage testing from a single test buildup, providing manufacturers with performance data more efficiently.

The addition of smoke leakage testing allows manufacturers to access both fire and smoke testing for doorsets through a single facility and technical team. Alongside testing, Warringtonfire also provides support with technical assessments, extended field of application reports and classification services, helping manufacturers build a clearer route from testing through to the final evidence package.

Preparing for future fire doorset classification

Establishing the fire resistance performance of doorsets remains fundamental, however organisations are increasingly being asked to demonstrate how complete doorset assemblies perform across a range of characteristics, including smoke control.

Testing is also being considered alongside other conformity assessment activities, including sampling, factory production control and audit testing which are designed to provide added assurance of product performance and form the basis of accredited third-party certification schemes, such as Q-Mark and Certifire.

The Warringtonfire-Birchwood facility provides Fire doorset testing

Manufacturers are being asked not only to demonstrate how products perform, but also how that performance is evidenced and maintained throughout the supply chain. Early engagement with testing specialists is also important.

By discussing intended applications, certification objectives and future product development plans before a programme begins, manufacturers can identify potential limitations and opportunities much earlier in the process.

In many cases, this helps avoid additional cost, project delays and unplanned testing further down the line. By considering fire resistance and smoke leakage together from the outset, organisations can simplify assessment and classification activities while building stronger foundations for future product development.

Supporting manufacturers from fire doorset testing to classification

The Warringtonfire Birchwood facility provides fire resistance testing, smoke leakage testing, technical assessment, extended field of application and classification support from a single location.

Whether the objective is supporting a new product launch, extending an existing product range or preparing for future classification requirements, Warringtonfire’s technical specialists can help develop testing programmes aligned with commercial and compliance objectives.

Maritime lithium-ion battery fire detection starts with heat

AP Sensing explains how fibre optic Linear Heat Detection enables earlier lithium-ion battery fire detection on ships through continuous thermal monitoring

On the open ocean, where a ship’s hull is its entire world, fire is one of the few threats that can escalate faster than a crew can respond. Today, that threat is increasingly linked to lithium ion batteries.

Once specialty cargo, they now move through global supply chains in huge volumes, powering electric vehicles, e-bikes, tools, laptops and portable electronics. The maritime industry understands how lithium ion batteries behave under failure conditions.

The chemistry is well studied and the progression from defect to thermal runaway is familiar. What remains difficult is spotting developing thermal events early enough to act. Conventional systems often react only once smoke or fire is visible.

At sea, earlier automatic detection and precise situational awareness can make a critical difference.

How lithium-ion battery fires begin at sea

A lithium ion battery failure usually begins quietly. A defect, manufacturing flaw or Lithium-Ion Battery Fires “The maritime industry understands how lithium ion batteries behave under failure conditions.” impact can cause a small, localised rise in temperature. Inside a battery pack or sealed container, that heat can build slowly and invisibly.

On ships, where containers are tightly stacked and airflow is limited, early detection is difficult. Monitoring still often relies on inspections and fire watches, but thermal events can develop between checks, especially where visibility is restricted.

This is why maritime fire safety is shifting from reacting to visible fire toward continuous, automated awareness of developing thermal conditions.

How fibre optic Linear Heat Detection works

Fibre optic Linear Heat Detection addresses this challenge by continuously monitoring temperature along the protected area.

AP Sensing uses a passive fibre optic sensor cable routed through the ship or cargo zone, creating a continuous sensing line rather than isolated detection points. Wherever the cable runs, temperature is measured.

The system provides thousands of temperature readings along the cable, creating a real time thermal map that updates every few seconds. If thresholds or abnormal thermal developments are detected, it automatically alarms on the bridge, helping crews assess and respond earlier.

How fibre optic sensing detects heat before fire

At the centre of the system is a controller that sends short laser pulses into an optical fibre. As light travels through the fibre, a tiny portion scatters back from every point along the sensor cable.

Part of these backscattered light changes with temperature, while another part remains stable. By comparing the two, the system calculates temperature at every point along the cable. It also measures how long the light takes to return, allowing localised temperature changes to be precisely located.

This creates a complete, real-time temperature profile across the monitored area, not just a reading at one hotspot. Operators can see where heat is developing, how temperatures change and whether a thermal event is spreading.

For lithium-ion battery cargo, where conditions can escalate rapidly, continuous awareness is critical.

Maritime lithium-ion battery fire detection proven at sea

Technology is already proven in demanding environments.

Fibre optic Linear Heat Detection has long been used as a certified special detector within fire alarm systems. Before lithium-ion batteries became a growing maritime concern, it was deployed across road and rail tunnels, parking garages, large photovoltaic installations and storage facilities.

In these settings, reliability is essential. Detection systems must perform despite contamination, electromagnetic interference, vibration, weather and other harsh influences.

Fibre optic LHD has demonstrated this resilience while helping operators maintain safety and avoid unnecessary interruptions. This history is important because the technology is not new to challenging conditions.

At sea, however, airflow, motion and operational constraints create a distinct detection challenge. To explore this, AP Sensing’s system was evaluated alongside conventional and alternative detection technologies in a major European and insurance research initiative focused on fire safety on RoRo (Roll on, roll off) and container vessels. Testing included laboratory work and long-term onboard trials under real operating conditions.

The findings contributed to the inclusion of fibre optic Linear Heat Detection in the maritime SOLAS Fire Safety Systems (FFS) Code in early 2026, reflecting growing recognition of continuous thermal monitoring in maritime fire protection.

AP Sensing’s solution is also DNV-approved for safety-critical ship environments. The results highlighted the limits of traditional smoke detection on ships. In controlled settings, smoke detectors performed well. At sea, airflow, humidity, salt aerosols and engine related particles could delay detection or increase nuisance alarms.

Fibre optic Linear Heat Detection was unaffected by these challenges. Because it measures temperature directly along the cable, it remained reliable regardless of airflow or airborne contaminants.

The trials also showed that the system can reveal how a thermal event develops. It pinpointed the heat source and helped operators track spread and direction, giving crews precise, real-time information instead of a general alarm.

Why fibre optic heat detection suits maritime fire safety

Beyond detection performance, fibre optic Linear Heat Detectors fit maritime operations. The sensing cable is passive and needs no electrical power along its length, simplifying installation and removing potential ignition sources.

The system also remains active during loading and unloading, when cargo handling introduces added risk.

How early heat detection improves maritime fire response

Detecting heat early is only part of the equation. What matters is how quickly and effectively that information becomes action. In a maritime environment, where response time is critical and access can be limited, crews need to know where something is happening and how it is evolving.

Fibre optic sensing provides this insight in real time. Temperature data is processed in the measuring unit and visualised through a graphical user interface (GUI), giving operators a continuous view of conditions across the vessel.

Alarm strategies can be configured around absolute temperatures or temperature gradients, enabling early warnings of abnormal developments before a localised issue escalates.

Lithium-ion battery fire detection beyond maritime transport

With lithium-ion batteries, the challenge does not begin or end at sea. A battery’s journey spans storage, transport, use and recycling. Across these stages, the pattern remains the same: heat develops before fire.

Fibre optic Linear Heat Detection applies this principle consistently. A continuous sensing cable enables early detection and precise localisation, supporting a unified approach to fire safety beyond maritime transport.

This is especially relevant in battery storage facilities, where large volumes of cells are concentrated in confined spaces and in recycling operations, where damaged or unstable batteries add risk during handling and processing.

Across these environments, the value is consistent: early insight enables faster, better-informed decisions and safer operations.

Meet AP Sensing at SMM Hamburg

At SMM maritime exhibition in Hamburg, September 1-4, discussions around lithium-ion battery safety and early fire detection will continue across the industry.

AP Sensing’s fire detection expert, Felix Heck, will be on site to present how fibre optic Linear Heat Detection and Distributed Fibre Optic Sensing are applied in real maritime environments. He will share how continuous thermal monitoring supports earlier detection and more informed response strategies.

Fire safety: from a compliance obligation to a strategic enabler of autonomous buildings

Susanne Seitz, CEO of Buildings Smart Infrastructure at Siemens , explains why digital, IoT-enabled fire safety systems are transforming fire protection

For decades, fire safety systems have been viewed primarily through the lens of compliance. Essential, yes – but rarely seen as a contributor to performance, resilience or sustainability. As buildings become smarter and more autonomous, that perspective needs to change.

Across industries, aging fire safety infrastructure often hides significant inefficiencies: high false alarm rates, disconnected systems, rising maintenance effort and limited ability to use data effectively. Facility teams spend up to 60% of their time validating false alarms rather than focusing on value-adding tasks.

In a world of tight budgets and skilled labor shortages, this is no longer sustainable. As energy systems evolve – for example, with the increased use of lithium-ion batteries in data centers – modern fire detection and protection become even more critical.

Modern, IoT-enabled fire safety systems fundamentally shift this reality. By embedding intelligence and connectivity, fire safety moves beyond an isolated layer to become an integral part of the digital building ecosystem.

This deeper integration allows fire safety data and events to inform and interact with other critical building systems – from triggering HVAC adjustments to contain smoke, to coordinating with access control for safe evacuation, or even informing building automation for optimized emergency responses.

The impact is tangible. Reactive maintenance becomes predictive planning. Periodic testing evolves into continuous, silent monitoring.

And with solutions like Building X Fire Apps, single-building oversight expands to portfolio-wide visibility, enabling consolidated management and insights across multiple sites.

This digital transformation also helps reduce false alarms by approximately 80%, significantly improving operational efficiency and occupant experience.

Digital fire safety also unlocks a new generation of services. Cloud connectivity, remote diagnostics, and advanced analytics allow technicians to arrive prepared, resolve issues faster, and reduce repeat visits – helping organizations cope with ongoing talent shortages.

At the same time, predictive insights enable smarter investment and data-driven lifecycle decisions.

Sustainability is another critical dimension. Targeted upgrades instead of full system replacements reduce electronic waste. Remote management lowers emissions by minimising the number of site visits. And advanced detection algorithms help avoid unnecessary emergency responses triggered by false alarms.

New technology is already beginning to deliver value across sectors. In healthcare, digital fire safety supports uptime and patient safety through data-driven operations. In higher education, it simplifies the management of complex campuses with diverse building types.

And in commercial real estate, it forms a foundation for more autonomous, scalable building operations.

The conclusion is clear: the question is no longer whether fire safety systems should be modernised, but how strategically can organisations approach it.

As we move toward autonomous buildings, fire safety must be digital-native, cybersecure and seamlessly integrated into the building’s intelligence layer. Those who rethink fire safety beyond compliance will unlock meaningful gains in operational performance, sustainability and long-term resilience.

Hochiki Training Academy launches FIREbeam course for beam smoke detection projects

Hochiki Europe has expanded its online Training Academy with a free course covering the FIREbeam beam smoke detection range for large open-space application

Hochiki Europe has expanded its online Training Academy with the launch of a new course focused on its FIREbeam beam smoke detection range.

Available free of charge to registered users, the course is designed to help installers, specifiers and distributors develop their knowledge of beam smoke detection and gain confidence in specifying and installing FIREbeam systems for projects involving large, open spaces.

The course introduces both products in the FIREbeam range, including the addressable FIREbeam Xtra and the conventional FIREbeam Conex, alongside the accessories available across the portfolio. It also covers the fundamentals of beam smoke detection, which is commonly used in environments where point detection is impractical, such as warehouses, shopping centres, sports halls, museums, hotel atriums and transport terminals.

The new module forms part of the Hochiki Training Academy, a free online learning platform created for professionals working with Hochiki products, including installers, distributors, specifiers and facilities teams. Courses are completed online, allowing users to learn at their own pace from any location. Each course concludes with an assessment, with successful learners receiving certification.

According to Hochiki Europe, the Academy has grown to more than 2,000 users in just a few years and is now used by businesses across the UK, Europe, the Middle East and Africa.

Martin Green, Commercial Training and Support Manager at Hochiki Europe, said: “The FIREbeam course is another building block in the Academy library. Whether someone is new to our products or has worked with Hochiki for years, the Academy is there to support learning throughout their career, not just at the point of installation or specification.

“Because it is entirely self-paced and accessible from anywhere, our customers can build their knowledge in a way that fits around their own working day, no matter where they are based. If you have a project coming up with a large open space, whether that is a warehouse, an atrium or a sports hall, this course gives you a solid grounding in the FIREbeam range before you get started.”

The FIREbeam training course is available now through the Hochiki Training Academy.

Ramtech deploys wireless fire detection system at 2026 Le Mans race

Ramtech has successfully deployed its wireless fire detection technology at the 2026 24 Hours of Le Mans, providing temporary fire protection across key event infrastructure and demonstrating the increasing adoption of automated fire safety systems at major motorsport events.

Working alongside event infrastructure specialist iEvent and integration partner Prodomo, Ramtech France installed a temporary network of more than 300 wireless devices, including smoke and heat detectors and manual call points. The system protected 14 team paddocks and the Genesis Hospitality Building throughout the event.

Installed on a one-month rental basis, the system delivered continuous 24/7 fire monitoring during both the event build-up and race period, with the core live system operating for one week.

The deployment follows a similar installation at the Formula 1 Hungarian Grand Prix, reflecting a broader trend among major motorsport organisers towards wireless fire protection systems that can be rapidly installed and adapted.

Bruna Esposito, Business Unit Director at Ramtech, said: “The environment at a modern Grand Prix or endurance race closely mirrors the extreme complexities of major commercial construction or industrial sites; massive temporary structures, constantly evolving site layouts, tight installation windows and millions of dollars in critical team assets. Managing these risks via manual human patrols is increasingly seen as an outdated and reactive liability.

“We are seeing a fundamental shift in how the world’s largest public events manage fire safety. Rather than relying on traditional, human-led fire watch personnel to manually patrol grounds, tier-one event organisers are embracing automated wireless safety technology to protect people and temporary infrastructure. This project represents an important milestone for Ramtech, demonstrating the trust that global event organisers place in our technology.”

Because the wireless mesh system requires no cabling or conduit, additional devices could be installed or relocated as site layouts evolved during the build-up to race day, allowing organisers to respond quickly to changing operational requirements.

Wireless system chosen for flexibility

Antoine Galicher, Project Manager at iEvent, said: “Flexibility was one of the key reasons we chose Ramtech’s WES system. For an event of this scale, we needed a solution that could deliver both reliability and ease of deployment, allowing us to adapt quickly as requirements changed. The wireless technology simplified installation while helping us maintain the high safety standards expected at Le Mans.”

Sylvain Castaignau, Business Development Manager for Ramtech France, added: “The customer was initially looking for a solution to improve fire safety but was not aware that an automated system like WES existed. From the first demonstration, it became clear that the flexibility and functionality of the system were perfectly suited to an event environment where requirements change daily. This project proves how temporary fire protection can evolve beyond traditional fire watch approaches.”

Ramtech highlights wider event safety trends

Ramtech believes the Le Mans project reflects a wider shift in temporary fire protection for large-scale events, where organisers are increasingly seeking alternatives to manual fire watch patrols.

Esposito said: “With the additional risk posed by increasing summer temperatures and prolonged heatwaves, relying on manual human labour for continuous fire watch patrols introduces major occupational health risks and soaring overtime costs. In addition, there is a heightened concern around the potential for outbreaks of fire, particularly in conditions of dry outdoor spaces, where events may be held.”

The company says the project demonstrates how wireless fire detection technology can provide flexible protection for temporary venues, particularly where layouts change frequently during construction and event preparation.

Gateway 2 lessons: Preparing construction projects for Gateway 3 success

Quelfire shares expert insights into the key lessons from Gateway 2, highlighting common compliance challenges and how construction teams can prepare for Gateway 3

In many ways, Gateway 2 has become the new normal. It’s already changing the industry for the better, especially for teams that genuinely want to get things right. That said, the industry isn’t fully there yet.

Some still hold the mindset of “we’ve always done it this way” and approach the Gateway regime as something they have to do, rather than as something that can make a real difference in how we design and construct buildings.

From our perspective at Quelfire, it’s a much-needed change that is pushing the industry toward better decisions and safer buildings – which can only be good things, surely? In early applications, Ishfaq was surprised by the disconnect between the Building Safety Regulator (BSR) teams and the construction industry.

He highlighted that there seemed to be no established process; some BSR teams used staged applications, while others required full submissions.

Some submissions completed in early Stages 3/4 with no contractor details were approved in 12 weeks, whereas other T1 contractors, for instance, provided thorough information on specific parts of the build and waited about 9 months for approval.

Ultimately, this suggests that the BSR was still very much working out its processes during this stage. Because the introduction of the Gateways was such a significant change for the industry, the focus has naturally been on the first stop-and-go gateway, Gateway 2.

However, as the built environment transitions beyond this, the next unknown is Gateway 3, which introduces a new level of uncertainty. Ishfaq raised concerns about potential delays from Gateway 3, especially given the delays experienced with the second Gateway.

He believes it hasn’t been “road tested enough yet” to know what it will entail; the industry is still waiting for feedback.

Where are construction projects still falling short at Gateway 2?

Typically, R5 Consultants will distribute their project schedule to key parties, ready for submission at Gateway 2.

However, upon receiving the completed schedule, the team often finds gaps in expectations and information, with each party often having different ideas about elements of the project.

Ishfaq said, “The challenge with firestopping is that it’s one of the few elements of construction that is genuinely collaborative. The architect will set their position of all these walls, the structural engineer will dictate what size the openings and letterboxes can be and then the M&E engineer needs to tell you what is actually passing through and where and then you can come to a resolution on what the firestopping needs to be.” What Ishfaq and his team are finding is that they’re getting pushback from consultants due to tight deadlines and rising costs, because they haven’t given enough time to Gateway requirements.

Furthermore, Whitty argued that contractors “can’t play the system anymore” and that part of the Gateway regime is about making concrete decisions and following them through on-site.

He said that hidden costs, along with having to redesign a project two or three times, slow development and cost a lot of money to resolve.

What does good Gateway 2 compliance actually look like?

The whole reason for the Building Safety Act 2022 and subsequent Gateways is to improve building safety and protect those in them. Early fire stopping engagement is the only way to ensure this, as it brings all key parties together at the design stage to discuss key deliverables and how they’ll be achieved.

It puts fire safety at the heart of every decision, ensuring the project is designed and then built around available fire stopping tested solutions. Ishfaq said that when looking at the mechanics of what you’re going to submit, it is about design procurement alongside product and system procurement.

If contractors review the information and decide on deliverables, a systematic approach can be taken to articulate it to the regulator.

Further to this, Whitty stated that main contractors need to be clear about and commit to products and systems they want to see in the building. He also raised that you’ve got to make it easy for the regulator to say yes.

You’re taking the BSR on a journey – give examples, show the rationale behind the decisions. This also includes being in dialogue with your regulator spokesperson and finding out what’s required of you: ask the questions.

All panellists agreed that it is better for project teams to take their time at the design stage and focus on getting it right the first time. Multiple redesigns cost time and money, add project pressure and stress and ultimately slow the whole project down.

You might discover that the BSR will ask for additional information after submission. By putting in the effort beforehand, you give yourself an advantage.

Thorough design may take time upfront, but it pays off in the long run for business security and profitability. Not to mention it prioritises building safety!

How can construction teams start preparing for Gateway 3 now?

Both Whitty and Ishfaq agreed that contractors need to improve their QA process. Whitty also went on to say that it’s about the execution of what you set out to do. It’s about evidencing that what you have installed is as per what you submitted at Gateway 2.

You can’t leave it to the last minute to prove how your piling went in, for example, you’ve got to be thinking about all of these things from the get-go.

Ultimately, no one knows what Gateway 3 will fully entail, so if you’re not preparing for it, start now. Willmott Dixon is preparing for Gateway 3 by enhancing its pre-start procedures, working through key deliverables before construction even begins.

The team goes through what they are building, what they will be evidencing and how often and what good looks like. Whitty stated that having these early on-site conversations has been driving value in production and efficiency and that there is generally less conflict on site.

By working closely with supply chain partners, behaviours become apparent. Their willingness to collaborate, but also how they plan, prepare and deliver to make Gateway 3 more achievable.

Are construction projects ready for Gateway 3?

While the built environment’s focus has been on Gateway 2, it highlights one question: Are we ready for what comes next? Gateway 3 is currently the big unknown. The unknown can be scary, but especially for those unprepared.

“We’ll deal with it later” can no longer be an option, as evidence is crucial to demonstrating that what is built is what was designed for Gateway 2. That means thinking ahead now and applying all practices across all projects.

Because, at the end of the day, this is about whole building safety and protecting lives. And sticking to the agreed plan.

This article is based on Quelfire’s London Build 2025 panel discussion, titled Gateway 2: What We Know Now. Craig Wells, Sales Director at Quelfire, was joined by Graeme Whitty, National Product Director at Willmott Dixon and Nasar Ishfaq, Director, Architect and Principal Designer at R5 Consultants, to discuss Gateway 2 and what they have learned since its introduction. However, this article touches on why you should look beyond Gateway 2 to Gateway 3. It also explains how to prepare for it.

PFAS-free fire extinguishers: future-proofing fire safety for sustainability and compliance

Andy Spence of Britannia Fire explains how fire safety professionals can prepare for PFAS restrictions, reduce carbon emissions and improve whole-life value through PFAS-free technology, circular economy principles and sustainable procurement

The fire safety sector is entering a period of significant change. Growing environmental expectations, evolving regulations surrounding PFAS and increasing pressure to reduce carbon emissions are prompting organisations to reassess how fire protection products are specified, managed and maintained throughout their lifecycle.

At the same time, budget constraints and supply chain considerations are placing greater emphasis on long-term value rather than upfront cost alone. Future proofing requires organisations to anticipate regulatory change, reduce environmental impact and invest in solutions that deliver long-term operational and financial benefits.

From PFAS free technologies to circular economy principles, the decisions made today will shape both sustainability performance and future resilience.

PFAS regulations and the fire safety challenge

Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS), known as ‘forever’ chemicals, have historically been used in firefighting foams and fire extinguishers because of their unique ability to rapidly suppress flammable liquid fires.

However, they are under intense scrutiny as they do not degrade easily in the environment and can lead to a range of health issues, including decreased fertility, developmental delays in children, a higher risk of certain cancers and immune system suppression.

Across the European Union, regulations restricting PFAS in firefighting foams and extinguishers came into force on 23 October 2025, with a ban in most scenarios taking effect from 23 October 2030. The UK government is also taking this issue seriously.

Earlier this year the Department for Environment, Food and Rural Affairs (Defra) published its PFAS plan, which outlines key steps the government will take to understand, manage and reduce exposure to PFAS. Some action is already being taken, with the Health & Safety Executive (HSE), the agency which regulates chemicals placed on the market in Great Britain (GB), due to report back later this year on how PFAS should be phased out of firefighting foam in the UK.

The HSE is suggesting a staggered approach to phasing out PFAS in firefighting foam and extinguishers, depending on use and type. Looking at the proposed timescales for transition, it’s unlikely fire extinguishers containing PFAS would be phased out before 2031, but what we do know is that they will probably be the first to go – in part due to advances in technology and credible alternatives.

We are expecting the HSE to publish its final opinion later this year, with a decision on UK wide restrictions to follow soon after. As PFAS bans take effect across the EU and the

UK moves towards tighter regulation, those responsible for fire safety need to evaluate their existing assets, develop transition strategies for equipment containing PFAS, budget for replacement costs and manage the complex requirements associated with disposal and environmental compliance.

Transitioning to PFAS-free fire extinguishers and foams

We recognised the detrimental effects of PFAS some time ago and removed them from all our products in 2024. Since then, we have been at the forefront of shaping future fire safety regulation in the UK.

In June last year, I addressed the Environmental Audit Committee in the House of Commons, sharing our experience of phasing out PFAS with the aim of helping policymakers understand both the environmental urgency and the practical realities of a transition.

The emergence of high performing PFAS free solutions is helping to dispel the myth that switching to PFAS free is a compromise. Britannia’s lightweight, composite P50 fire extinguishers are a prime example of how the industry is evolving, combining proven fire suppression performance with PFAS free technology and a reduced environmental footprint.

They are tried and tested in the real world, meaning organisations can confidently transition away from PFAS while maintaining the levels of protection, reliability and compliance that modern fire safety demands.

Organisations need to start thinking about this now. They should review their stock to establish what needs replacing and put in place an action plan as part of their usual fire risk assessments and in accordance with their health and safety asset management plan.

If existing stock is nearing its end of life, has failed an inspection or Knowledge Partner additional units are required, make the switch and get ahead of the ban. Allow time for transition but don’t panic.

Use a reputable supplier that will support and provide advice throughout the process.

Circular economy principles for sustainable fire protection

Future-proofing fire safety requires organisations to look beyond the initial purchase cost and consider the entire lifecycle of their fire protection assets. Factors such as maintenance requirements, replacement frequency, waste generation and end-of-life disposal all contribute to the true environmental and financial cost of a product.

Adopting a lifecycle approach enables organisations to identify solutions that deliver long-term value, reduce resource consumption and minimise carbon emissions. In an era of increasing sustainability expectations, understanding the full lifecycle impact of fire safety equipment is becoming just as important as assessing its firefighting performance.

Composite fire extinguishers and long-life fire safety equipment

Traditionally, steel fire extinguishers have been the go-to solution for facilities managers and fire safety professionals, but they are prone to corrosion and therefore need servicing every year and often replacing every five years.

Composite fire extinguishers, however, are helping organisations to meet stringent waste and carbon reduction targets and simplifying fire safety. They’re made from a unique combination of durable plastic and aramid fibres, meaning they are strong, don’t corrode and therefore last 20 years.

They don’t require costly annual servicing, just simple, efficient in-house checks done as part of an organisation’s routine maintenance programme and a full refurbishment after 10 years.

They are also multipurpose, meaning organisations don’t need as many. Britannia’s composite P50 fire extinguishers are used worldwide and despite some claims to the contrary, they conform to all required regulations and standards, including BS EN3-7.

Delivering long-term cost savings Sustainable products like the P50 are well positioned to deliver long-term savings. High-quality, long-lasting equipment with reduced maintenance and replacement requirements lowers ongoing operational costs, while PFAS free solutions help organisations avoid future disposal expenses and compliance challenges associated with evolving regulations.

P50s are also multi-purpose, capable of tackling Class A and B fires as well as electrical fires, reducing the number of extinguishers needed and saving money.

By taking a whole-life cost approach, organisations can identify solutions that not only support sustainability objectives but also deliver measurable financial benefits over time.

Reducing carbon emissions across the fire safety lifecycle

Manufacturing, transportation, maintenance and end-of-life disposal all contribute to a product’s overall carbon footprint, making it important to look beyond operational performance alone.

By assessing lifecycle emissions rather than simply focusing on purchase price, organisations can identify opportunities to significantly reduce their environmental impact.

For example, selecting composite fire extinguishers that don’t require annual servicing reduces vehicle journeys and associated emissions, while products that don’t need frequently replacing, lowers the carbon costs linked to manufacturing and transportation.

They are also fully recyclable, with solar assisted, low energy manufacturing helping to minimise their carbon footprint. Choosing durable, reusable and recyclable fire safety equipment can therefore make a meaningful contribution to both carbon reduction targets and wider sustainability objectives.

Future-proofing fire safety with sustainable compliance strategies

Fire safety and sustainability are no longer separate considerations. By embracing PFAS-free technologies, lifecycle thinking and circular economy principles today, organisations can strengthen compliance, reduce costs and improve environmental performance. This will ensure that those organisations are well prepared for the challenges and opportunities of the future.

How UL Solutions supports confidence in passive fire protection

Product development in today’s built environment is accelerating. Manufacturers must address evolving project needs, support complex designs, and deliver solutions quickly. However, in life safety categories, speed must not compromise confidence, compliance, or performance.

At Siderise®, innovation in passive fire protection is grounded in practice. Each solution is validated through rigorous testing, certification, auditing, and quality control to ensure safer construction in real-world applications.

Why certification matters in life safety applications

This commitment was recently emphasized by Sreenivas Narayanan, Global Partnerships Director at Siderise, who collaborates with UL Solutions to efficiently bring passive fire protection products to market while meeting safety requirements.

He states, “UL Certification has been more than just a compliance step for us; it’s been a key enabler in building credibility across markets where trust and performance matter most. As we expand globally, having a recognized and robust framework helps align stakeholders from consultants to contractors around proven solutions.”

In passive fire protection, all stakeholders require assurance that products have been independently evaluated and meet safety standards. UL Solutions supports manufacturers by testing and certifying products to requirements.

The UL Mark demonstrates compliance and builds credibility. Siderise works with UL Solutions to test and certify products for curtain wall, facade, and perimeter barrier applications, including firestops, spandrel insulation, and barrier systems. Products like the Siderise CW-FS Firestop hold cUL-US and UL-EU certifications, confirming their suitability for demanding conditions.

Why third-party certification matters

These certifications reassure project teams by confirming that Siderise solutions have been independently assessed for fire resistance and safety. UL’s third-party certification extends beyond product testing to include audits of raw materials, batch traceability, process controls, and quality management, ensuring consistency from development to production.

With evolving codes and compliance requirements, manufacturers also need technical guidance from experienced engineers who understand relevant standards, their impact on product development, and how to navigate the certification process effectively.

UL Solutions provided this support to Siderise, identifying relevant standards, evaluating testing pathways, and guiding Siderise through complex requirements. This involvement enabled informed decisions, reduced delays, and supported product development.

Flexible support for product development

Because delays in testing or certification may impact product launches, customer commitments, and market opportunities, UL Solutions supports progress at key stages.

With regional labs, local teams, and flexible testing options, they improved communication, streamlined coordination, and enabled more efficient timelines. Witness testing at third-party labs or customer sites also helps manage costs and accelerate time-to-market while maintaining compliance.

For Siderise, this flexibility enabled ongoing product development without compromising the safety, quality, or standards essential to passive fire protection.

As building design advances, the demand for tested and certified passive fire protection solutions increases. Manufacturers must demonstrate that their products meet modern safety and compliance standards. Through collaboration with UL Solutions, Siderise combines innovation with independent validation

Fire safety compliance for housing providers: Beyond waking watch

Hyfire’s Brett Boyd explains how wireless fire detection is helping housing providers achieve fire safety compliance and reduce reliance on waking watch

For housing providers across the UK, fire safety compliance remains one of the most pressing challenges facing the sector.

As organisations continue to address issues including unsafe cladding, compartmentation failures and inadequate fire stopping, there is increasing pressure to find solutions that not only meet regulatory requirements but can be implemented quickly, cost-effectively and with minimal disruption to residents.

The launch of the Interim Measures Alarm Fund (IMAF) by Homes England in April 2026 is designed to help tackle that challenge, providing funding for housing providers to upgrade fire safety systems in buildings where urgent remedial works are required.

According to Brett Boyd, Regional Sales Manager – South East at Hyfire, the fund represents far more than a financial opportunity. “Compliance is at the centre of it all,” he says. “It’s not just about ticking boxes to access the funding. It’s about making sure systems are actually doing what they’re supposed to do, and that’s protecting people.”

The introduction of IMAF comes at a time when many housing providers are seeking alternatives to temporary fire safety measures while remediation projects are undertaken.

In particular, the industry continues to look for ways to reduce reliance on waking watch arrangements, which can be expensive to maintain over extended periods.

“A big driver behind it has been the need to move away from costly measures like waking watch and towards a more cost-effective and more permanent solution,” says Boyd.

For landlords and building managers, compliance is increasingly about demonstrating that buildings are safe while also providing reassurance to residents.

“Being compliant means housing providers can demonstrate that they are meeting their obligations and can safely step away from things like waking watch, which can be both disruptive and expensive over time,” he explains.

“At the end of the day, compliance gives everyone confidence, from the landlords to the residents. It’s the right level of protection that needs to be in place.”

Delivering fire safety compliance without complexity

While funding provides an opportunity for improvement, implementing compliant fire safety systems can still present practical challenges.

This is particularly true in occupied residential buildings, where traditional hardwired installations can create disruption for residents and significantly extend project timescales.

For Boyd, one of the key advantages of Hyfire’s Taurus system is that compliance has been built into the technology from the outset. “Taurus was developed with real-world challenges in mind, so compliance is built into what we do,” he says.

“Our systems are fully certified and designed to align with the standards that sit behind funding schemes like IMAF.”

However, Boyd is quick to point out that technology alone is only part of the solution.  “One of our big advantages is our network of approved installers,” he explains. “It means organisations aren’t just getting the technology, but also the right expertise to deliver a compliant solution from start to finish.”

That installer network plays an important role in ensuring systems are delivered correctly and in accordance with the latest requirements.

“Installers understand both the technical side and the compliance requirements, which makes the whole process much smoother,” he says.

The flexibility of wireless technology also helps simplify projects that might otherwise be difficult to deliver.

“Because it’s wireless, it gives a lot more flexibility when designing and installing, particularly in buildings where running cables would be difficult or disruptive.” In many cases, speed can be just as important as compliance.

“It’s particularly effective in situations where a fast upgrade is needed,” Boyd adds, revealing that ultimately the goal is straightforward.

“It’s about making compliance more achievable, helping organisations meet funding criteria without overcomplicating the projects that they’re working on.”

Why wireless fire detection is changing the conversation

Wireless fire detection systems have evolved significantly over the last two decades and are increasingly becoming a preferred solution rather than a specialist alternative.

According to Boyd, the technology has transformed the way retrofit projects can be delivered. “Wireless has been a game changer, especially for retrofit projects,” he says.

 “The biggest benefit is the lack of disruption. There’s no need to run cabling through walls and ceilings. Residents can stay in their homes while the system is installed.” For housing providers managing occupied residential buildings, that ability to complete works without requiring residents to relocate can deliver major benefits.

Speed is another important factor. “It’s also much quicker to install, which naturally helps keep costs under control when you look at a whole project,” Boyd explains. “Given the ongoing cost of waking watch, that speed can make a real financial difference.”

One misconception that still occasionally exists within the market is that wireless systems may not offer the same level of reliability as traditional wired installations.

Boyd is keen to challenge that perception. “Modern wireless systems are incredibly robust and perform to the same standards as wired systems,” he says. “There’s no compromise there.” He believes the flexibility of wireless technology is another significant advantage.

“Buildings can change over time and wireless systems can make it easy to adapt without needing major works again in the future.”

Overall, he says, the benefits are clear. “It’s about delivering a safer compliance solution in a way that works for both the building and the people that live in that building.”

Adapting to changing fire safety regulations

As regulations continue to evolve, flexibility is becoming an increasingly valuable feature of fire safety systems. One example is BS 8629, the standard covering evacuation alert systems for use by fire and rescue services in blocks of flats.

For many building owners, the prospect of upgrading systems to meet new requirements can raise concerns about cost and disruption. However, Boyd says this is often not necessary with HyFire systems.

“One of the strengths of Hyfire is how adaptable our system is,” he explains. “If a building needs to meet the requirements of BS 8629, it’s often not a case of ripping everything out and starting again. Instead, we can build on what’s already there.”

In many cases, the process is relatively straightforward. “With proper planning from the outset of a project, it can be as simple as changing out the panel, removing the automatic detectors and doing some basic reprogramming of the system.”

The wireless nature of the technology once again provides a major advantage. “Because it’s wireless, those changes can usually be made without major disruption as well,” Boyd says.

“Residents don’t need to leave their homes.” The approach not only helps simplify compliance but also protects previous investment. “Overall, it’s a pretty straightforward upgrade and it helps protect the original investment in the system as well.”

The future of fire safety compliance

Despite the progress that has been made, Boyd believes housing providers still face considerable challenges. “There’s obviously a lot for housing providers to consider and manage at the moment,” he says.

“Things like compartmentation, unsafe cladding on buildings and substandard fire stopping are major contributing factors and they need to be addressed.” While waking watch remains a common response during remediation works, he believes the industry is increasingly recognising the limitations of the approach.

“While they do provide short-term reassurance, they’re not a sustainable solution and can become very costly over time,” he says. “There’s also the human element to waking watch, where it’s not always as reliable as it should be. Having an automatic detection system can sometimes be a more reliable solution.”

Looking ahead, Boyd sees wireless technology becoming even more prominent across the residential sector. “Where wireless was traditionally always used where cabling couldn’t be installed as a must-have solution, it’s now becoming a go-to solution for a lot of people because the technology has improved over the last two decades.”

Future developments are likely to focus on connectivity and visibility, helping housing providers manage fire safety more effectively across their portfolios. “There’s going to be a bigger focus on smarter, more connected systems that can give housing providers better oversight and control.”

At the same time, resident experience will remain central to decision-making. “When it comes to IMAF, it’s important to note that everything will continue to centre around the residents,” Boyd says.

“The improvements don’t come at a cost of comfort or convenience.” For Hyfire, the long-term objective remains simple.

“We believe in providing the right solution,” he says. “It’s not just about putting something in. It’s the right solution for the right application, solutions that meet the highest standards of safety while still being practical and efficient for the environments that they serve.”
