Ensuring corrosion protection: How AGF Manufacturing helps facility managers extend sprinkler system life

AFG Manufacturing explores how corrosion threatens fire sprinkler systems, why standard maintenance isn’t enough and what facility managers can do to prevent system failure

Corrosion poses a significant threat in fire sprinkler systems, often remaining undetected until it’s too late.

When corrosion compromises the integrity of these systems, it can lead to leaks that result in property damage and, more alarmingly, failure during a fire event, potentially resulting in loss of life.

Despite strict adherence to Inspection, Testing and Maintenance (ITM) protocols, corrosion continues to be a persistent challenge.

Traditional ITM protocols are essential for ensuring system reliability, but they can also inadvertently accelerate corrosion rates.

This occurs because maintenance activities often involve draining and refilling the system, which introduces fresh oxygen into the pipes, fueling the corrosion process.

Fortunately, advancements in corrosion prevention strategies and technologies have provided the fire protection industry with innovative ways to combat this issue.

By integrating modern corrosion monitoring and mitigation techniques, facility managers can enhance the longevity and effectiveness of fire sprinkler systems, ultimately improving life safety outcomes.

Understanding the corrosion triangle

Corrosion in fire sprinkler systems is the result of a chemical reaction that produces rust particles.

Unlike conventional plumbing systems where continuous water flow flushes away these particles, fire sprinkler systems are typically stagnant, allowing rust and debris to accumulate over time.

This buildup can lead to obstructions within the piping network, increasing the risk of reduced water flow or complete blockages.

In a fire emergency, such obstructions could prevent sprinkler heads from effectively discharging water, thereby exacerbating property damage and endangering lives.

The corrosion triangle consists of three essential elements: steel, water and oxygen.

When all three are present, corrosion is inevitable.

Fire sprinkler systems create an ideal environment for corrosion due to the continuous presence of these elements.

While wet systems remain filled with water and oxygen, dry systems are not immune to corrosion, as they still contain trapped moisture and oxygen.

Even small amounts of residual water in a dry system can trigger significant corrosion over time.

Strategies for mitigating corrosion risks

Eliminating any component of the corrosion triangle halts the corrosion process.

While completely removing steel, water, or oxygen is impractical, effective strategies exist to minimise their interaction, significantly reducing corrosion rates.

Venting trapped air in wet systems

One of the most effective methods to mitigate corrosion in wet pipe systems that utilise metallic piping, is venting trapped air.

Studies have demonstrated that removing trapped air increases the lifespan of pipes by reducing the amount of dissolved oxygen in the water.

To address this issue, the 2016 edition of NFPA 13 introduced a requirement for air vents in wet pipe systems constructed with metallic piping.

These vents release trapped air, preventing oxygen pockets from accelerating corrosion.

Draining condensation in dry systems

Dry pipe systems are designed to be free of water until activated, but condensation often forms within the pipes.

If not properly drained, this residual water can contribute to corrosion over time.

Ensuring that dry systems are installed with appropriate piping pitch and low-point drains is essential for preventing trapped water from stagnating within the system.

Corrosion inhibitors in dry systems

In addition to proper drainage, new technologies like “Vapor Pipe Shield” by General Air Products help combat corrosion in dry systems.

This system disperses a vapor-based corrosion inhibitor throughout the piping, creating a protective barrier between the steel and any residual moisture.

The role of inspection, testing and maintenance

Routine ITM schedules are designed to detect and address performance issues before they become critical.

However, wet systems are particularly susceptible to corrosion during maintenance activities.

Each time a wet system is drained and refilled, fresh oxygen is introduced into the water, accelerating the corrosion process.

Additionally, oxygen-rich air pockets often accumulate at high points in the system, further exacerbating the problem.

Recognising this, NFPA 13 has mandated the use of air vents in wet systems to mitigate corrosion risks.

One overlooked factor in corrosion prevention is the oxygen dissolved in the water itself.

During scheduled testing, fresh water, rich in oxygen, is introduced into the system.

To counteract this, recirculation systems such as those offered by AGF Manufacturing can be used to limit the introduction of new oxygen into the system.

Not only do these systems reduce corrosion, but they also conserve thousands of gallons of water annually, aligning with sustainability initiatives and reducing unnecessary waste.

Monitoring and preventing corrosion

Implementing corrosion monitoring is crucial for identifying potential risks before they escalate.

Various monitoring methods allow facility managers to track corrosion progression accurately, providing early warnings and enabling proactive maintenance.

Powered corrosion monitoring devices

These devices provide real-time data on corrosion rates, alerting personnel to significant changes within the system.

Corrosion coupons

Corrosion coupons involve placing a metal sample inside the system, which is later analysed to determine corrosion levels over time.

While not real-time, they offer valuable insights into long-term corrosion trends.

Passive corrosion monitors

Simple and cost-effective, these monitors indicate whether corrosion is occurring within the system, enabling early intervention.

By integrating these monitoring techniques, facility managers can gain a comprehensive understanding of the corrosion conditions within their fire sprinkler systems and implement corrective actions before severe damage occurs.

Why a remote inspector’s test valve is not a good air vent

Proper air venting is essential for reducing corrosion in wet pipe fire sprinkler systems.

NFPA 13 allows for multiple venting methods, including a manual valve, an automatic air vent, or a remote inspector’s test valve.

However, using an inspector’s test valve as an air vent is ineffective.

An inspector’s test valve is designed to simulate sprinkler activation and verify system functionality, not to provide continuous air removal.

Its typical placement is for testing purposes rather than at the system’s highest point, where air naturally accumulates.

Once water fills the vertical pipe leading to the drain, air can no longer escape, leaving pockets trapped in horizontal sections.

A dedicated air vent, such as an automatic or manual vent, is a better solution.

Automatic air vents continuously release trapped air, reducing maintenance needs and corrosion risks.

Manual vents require operation but provide controlled air release.

Properly placed remote inspector’s test valves could function as vents, but their accessibility for testing may be compromised.

NFPA 13 includes remote inspector’s test valves in its list of air venting methods, but their limitations make them unsuitable for effective air removal.

To prevent corrosion, maintain system integrity, and comply with NFPA 13, fire protection professionals should prioritize dedicated air venting solutions.

Installing the right venting strategy ensures system reliability and longevity while minimizing maintenance challenges.

Taking Action Against Corrosion

Effective corrosion management requires a proactive approach.

The integration of air vents, recirculation systems, corrosion inhibitors and monitoring devices significantly reduces corrosion risks and extends the lifespan of fire sprinkler systems.

Additionally, partnering with trusted manufacturers like AGF Manufacturing ensures access to high-quality corrosion prevention products tailored to the specific needs of fire protection systems in various environments.

From automatic air venting valves to innovative recirculation solutions, AGF offers a comprehensive range of products designed to enhance system longevity, reliability, and overall performance.

To safeguard lives and property, facility managers, fire protection engineers and building owners must remain vigilant against corrosion threats.

By implementing best practices in corrosion prevention and leveraging advanced technologies, they can ensure that fire sprinkler systems remain operational and effective when needed most.

Consumer awareness of PFAS chemicals remains low in the UK, CheckFire report finds

More than half of UK consumers unaware of PFAS chemicals

A new report from fire trade supplier CheckFire highlights a gap in public awareness of per- and polyfluoroalkyl substances (PFAS), often called “forever chemicals.”

The report, based on a survey of 2,001 UK consumers conducted by Censuswide, found that 56% of respondents had never heard of PFAS.

Awareness was particularly low among those over 55, with 70% unfamiliar with the substances.

Once informed of the potential environmental and health risks, concern among consumers increased to 68%.

Over a quarter of respondents (27%) reported being extremely concerned about PFAS exposure.

Consumer demand for PFAS-free alternatives grows

The study found that 79% of consumers would switch to PFAS-free products, even at a higher cost.

Nearly one in ten respondents (9%) had already made the switch, while three-quarters (75%) supported stricter regulations on PFAS use. Within this group, 43% strongly backed a full ban in the UK.

Bruce Robins, director of CheckFire, said: “As regulatory momentum builds, businesses must lead the transition to a PFAS-free future.

“Our new report emphasises the responsibility and opportunity for companies to act now – aligning with upcoming EU legislation, anticipated UK measures, and the rising consumer demand for safer alternatives.”

Regulatory changes drive industry response

The European Union has set a target to ban PFAS by 2030, while UK authorities are reviewing restrictions.

PFAS chemicals, numbering over 12,000 synthetic compounds, have been widely used for their resistance to heat, water, and oil.

They are found in products such as firefighting foams, non-stick cookware, and waterproof clothing.

Growing concerns about their persistence in the environment and potential links to health risks are leading industries to explore alternatives, particularly within the fire safety sector.

CheckFire develops PFAS-free solutions

CheckFire has introduced The Green Crosshair, a symbol marking its PFAS-free Commander and CommanderEDGE fire extinguishers under The Green Range.

The company continues to develop alternative solutions that align with environmental regulations and industry safety standards.

The report suggests that businesses across various sectors will need to respond to evolving consumer expectations and legislative changes by investing in PFAS-free technologies.

Change for the better with Britannia Fire

Andy Spence, Joint Managing Director, explains how Britannia Fire is leading the way with composite fire extinguishers

Britannia Fire recently made the decision to shift focus entirely to its composite P50 fire extinguisher range and investing over £1 million to expand production.

These long-lasting, PFAS-free extinguishers offer a cost-effective and environmentally friendly alternative to traditional metal models.

With regulatory changes on the horizon, demand for safer, easier-to-maintain extinguishers is growing.

In this interview, Andy Spence, Joint Managing Director at Britannia Fire, explains why the company has made these changes, how the industry is responding, what the future holds for fire safety and why the company decided to become the Platinum Partner for the IFSJ Leaders in Fire & Safety Conference 2025.

What led Britannia Fire to focus entirely on the composite P50 extinguisher range?

We had been manufacturing metal extinguishers from 1970 and established a solid reputation for quality, but our data showed that for every 1,000 P50 units we sold, we only sold one metal unit.

We found ourselves devoting a large section of our factory to making something that hardly moved.

Roger Carr, our founder, was understandably reluctant to give up a product range the company was built upon and has been fundamental for us for so long, but once the decision was made, we cleared out the metal production line and began pouring all our resources into the P50 line, which is what our customers actually wanted.

We felt it was time to concentrate on a model that is simpler to look after, resists corrosion and fits the shift towards longer-lasting extinguishers.

How do composite P50 extinguishers differ from traditional metal ones in terms of durability and maintenance?

The P50 is built with a composite cylinder that resists rust, so it keeps its integrity over many years without the same issues you get with steel.

Metal extinguishers can suffer from corrosion, especially in sites exposed to moisture or chemicals, which leads to costly servicing or replacements.

By contrast, the P50 needs only an annual visual check carried out by trained staff rather than a full discharge or internal examination.

This change in materials and design also means fewer seals and parts that degrade, which lowers the risk of leaks or other faults.

End users save time and money because they do not have to book service visits as often and do not need to replace corroded units.

Why do you believe the traditional annual servicing model is outdated for many users?

Servicing protocols were established when metal extinguishers were the norm and more prone to internal corrosion.

That justified opening them each year to test the lining, seals and pressure.

Modern technology fixes many of these issues before they start.

If the cylinder cannot rust, it does not need the same depth of inspection to remain safe and compliant.

We see this move away from constant servicing across various industries, where products are made stronger and need less intervention.

For end users, frequent servicing becomes a significant overhead, involving contractor fees, downtime for each unit and strict record-keeping.

By adopting composites, organisations can remove much of that hassle.

How does a multi-purpose composite extinguisher help people act more decisively in an emergency?

When there is a fire, especially a small one that has just started, people might panic about which extinguisher to pick up.

If there is a water model, a foam model and a CO₂ on the wall, it is easy to hesitate.

A multi-purpose composite like the P50 can cover most fire classes present in an office, warehouse or industrial setting.

If staff know there is only one extinguisher to think about, they are more likely to grab it straight away, aim it at the flames and put them out while they are still manageable.

This immediate response can prevent a minor bin fire from turning into a major incident, which obviously saves lives and property.

You have invested over £1 million in factory upgrades – why is it significant?

Previously, we had parallel production processes: one for traditional metal extinguishers and another for composite extinguishers.

The old metal line was more like a traditional workshop with rolling, degreasing, painting, and other steps that involved heavier machinery and a lot of space.

The composite line, by contrast, focuses on clean manufacturing processes, including filament winding.

With our new investment, we’ve added modern winding machines and reorganized the factory floor so that we can increase our P50 output by roughly 150%.

The environment is brighter, cleaner, and more efficient for our staff.

We’re reducing lead times, improving consistency, and creating a workplace that supports higher production volumes while maintaining quality standards.

A quicker turnaround makes it easier for clients to plan their fire safety upgrades or respond to last-minute needs.

We’ve also taken on new contracts, not just in the UK but in several European markets, so our existing capacity was being pushed to its limits.

Reducing lead times to four weeks helps us serve both new and long-standing customers without compromising on quality.

It also means that major clients who possibly manage hundreds or even thousands of units can streamline their project timelines.

They won’t be stuck waiting for months to receive equipment that’s crucial for compliance and on-site safety.

With PFAS-containing extinguishers expected to be banned, how is Britannia Fire preparing for this change?

We were one of the first UK-based manufacturers to eliminate PFAS from our extinguishers because we could see that regulators were likely to impose strict bans or limits.

By moving early, we avoided any scramble to reformulate foam agents or deal with leftover stock.

While the formal ban isn’t in place yet, it’s widely expected.

Being a UK manufacturer helps us adapt quickly because we’re not dependent on long supply chains from overseas.

We also have our own on-site fire test facility.

That lets us run tests on different foams, agents, and nozzles.

Whenever new regulations come in, we can adjust formulations and verify that they meet the required performance standards.

Having direct control over our manufacturing and testing speeds up our response to any regulatory change.

How are you disposing of old extinguishers responsibly, especially those with chemicals that might be restricted in future?

Responsible disposal has become a significant issue, especially with the shift away from PFAS and PFOA.

Last year, we set up a dedicated recycling centre at a separate site.

This facility handles returns of both composite P50 and metal models, allowing us to disassemble them and recycle or safely discard all components.

We know exactly where the extinguishers go and how they’re processed.

We keep full documentation for disposal, which provides transparency to our customers and helps us comply with waste management regulations.

Unfortunately, there have been cases in the past where old extinguishers ended up in the wrong places or were scrapped inappropriately.

By taking this in-house, we ensure everything is handled correctly from start to finish.

What savings and other advantages have large clients like Heathrow Airport and Anglian Water experienced with the P50 range?

A lot of people focus first on financial savings.

Heathrow saved over £1 million, while Anglian Water saved around £500,000 in total costs, but those figures only tell part of the story.

When you eliminate the need for annual servicing, you also reduce logistical complexities, like having service crews walking around the site or requiring security clearances and inductions.

There’s also a carbon footprint benefit.

If you don’t have vehicles and personnel traveling to each location every year, you cut down on emissions.

Anglian Water recently began its second 10-year period with our P50 range.

They’re replacing their original P50 units with new ones, giving them another full decade of service.

They’ve appreciated the reliability, the lower operational costs, and the reduced waste.

How do you see the fire safety industry evolving and what role will composite extinguishers play?

We talk frequently about quality.

Many manufacturers focus on cost reduction or mass production, but when it comes to protecting lives, buildings, and infrastructure, the lowest-priced option is not always the wisest choice.

A large business with valuable assets wants to make sure it’s well protected.

Composite extinguishers like the P50 align with that logic.

They’re tested to high standards, maintain consistent performance over their lifespan, and reduce the likelihood of a product failure when it matters most.

I believe we’ll see more companies moving toward composite solutions and away from traditional metal units that can corrode or require multiple services over a shorter lifespan.

What motivated Britannia Fire to become Platinum Partner for the IFSJ Leaders in Fire & Safety Conference 2025?

We exhibited at the IFSJ event in the Middle East last year and were impressed by the calibre of attendees.

Instead of casual browsers, we found serious decision-makers who understood what our product could offer.

We’ve done trade shows like Intersec for around 15 years, but those events often attract a wide mix of visitors and it can be hard to find potential buyers who are genuinely seeking specialised equipment.

At IFSJ Leaders, we had far more in-depth conversations with senior-level professionals who recognised the advantages of the P50 range.

The Platinum Partnership made sense because it gives us a prominent platform to reach the right audience in a market that values both high performance and low maintenance.

Our goals for the Middle East are straightforward.

We want to help major projects and businesses in that region improve their fire safety with an extinguisher solution that’s built to handle harsh conditions and reduce total cost of ownership.

The Middle East has plenty of large-scale facilities—airports, oil refineries, desalination plants, and more—where the reliability and resilience of our product can make a real difference.

From space tech to fire safety: The innovation behind MAUS Fire’s Stixx Pro

Thomas Hughes, Managing Director of Aerocom UK and MAUS UK, discusses Stixx Pro’s role in safeguarding enclosed spaces from electrical fire risks

MAUS Fire Safety has developed a fire suppression system called the Stixx Pro, designed to protect enclosed areas vulnerable to electrical fires.

This system, featuring a potassium-based extinguishing agent, stands out due to its fully autonomous operation, requiring no power or maintenance.

In this interview, we speak to Thomas Hughes, Managing Director of Aerocom UK and MAUS UK, to learn more about the company’s vision, the unique features of the Stixx Pro and how this product addresses critical fire safety challenges, particularly in areas like EV charging points and electric scooters.

Could you start by telling us a bit about MAUS Fire Safety?

The technology used within MAUS Fire safety devices originated from a space program in the 1980s.

There was a need to develop a technology that could extinguish all types of fires without destroying the expensive technology inside the spaceships.

MAUS took that technology and placed it in small devices to protect people and buildings on earth.

The devices are based around a patented potassium smoke and as a result is a more effective extinguishing agent than conventional powder.

What motivated MAUS to focus on developing fire suppression systems for enclosed areas prone to electrical fires?

The motivation for developing fire suppression systems for enclosed areas prone to electrical fires came from irreversible amounts of damage and ever increasing risk to life, created by preventable fires.

Massive amounts of destruction created as a result of a small fires ignited by faulty sockets or outlets, components overheating, outdated wiring, old appliances and loose components.

There are fire extinguishers out there that can extinguish electrical fires, yes, but none of them can fit inside or automatically extinguish and leave no residue within the electrical cabinets and enclosures where they are almost always ignited from.

There was a severe gap in fire extinguishing capabilities and our MAUS system solves that.

A super compact, simple, quick, easy, self-adhesive device that is automatically activated when a fire starts, our device extinguishes the fire before it spreads and eliminates any need for wide scale evacuation, reactive damage control and intensive clean up.

Can you introduce the Stixx Pro fire suppression system and what makes it different from conventional solutions?

The MAUS Stixx Pro fire suppression system works in the form of a solid substance potassium compound.

Our Heat detecting cable will activate automatically once a fire is detected at 170’c.

This then creates a chain reaction into activating the potassium compound which is released as very small particles of gas.

These potassium gas particles interrupt the chemical combustion reaction by neutralising the hydrogen, oxygen and hydroxide radicles within the flame.

Therefore, suppressing and extinguishing the fire.

Our system is residue free and will cause no further damage.

What does the potassium-based extinguishing agent used in the Stixx Pro do?

The MAUS Stixx extinguishing agent works in the form of a solid substance potassium compound, activated only by HDC detecting a fire at a temperature of  >170’c.

Our device is considered environmentally friendly because of a few reasons; Our plastic shell is 100% recyclable.

Secondly, due to our agent being a solid substance potassium compound it can be disposed of safely.

Our system has zero Global Warming Potential (GWP) and negligible Atmospheric lifetime (ALT).

 Our systems are ozone-friendly and contain no CFC’s.

We are committed to environmental sustainability in both our technology and business practices as we continually strive to reduce our overall carbon footprint.

What are the benefits of the system being autonomous in environments like EV charging points?

The benefits of our system being autonomous or not requiring any electricity or wiring means that installers can discreetly and easily retrofit, specify, or implement it into the workings of both EV charging points and Scooter stations.

As a result of our system not needing any wires, batteries or power, they can be installed very quickly and without any disruption.

They have a manufacturer’s warranty of five years with zero maintenance, this means that once installed (unless there is a fire and they have been activated) you will only need to renew and replace every five years.

The Stixx Pro provides “100% flooding” once activated.

What does this mean?

Our MAUS Stixx Pro series comes with a recommended ‘volumetrically protected area’ for each different device.

If the volumetric area recommendation is followed, then upon activation, the potassium gas with completely flood the entire area within seconds which allows maximum surface area for the potassium gas particles to interrupt the chemical combustion of the fire.

To go into more detail of how that works; The falling speed of the Potassium particles decreases with a smaller diameter as the surface becomes large in relation to the mass, which means that air resistance becomes relatively large in relation to the force of gravity.

This results in the particles remaining suspended for a longer time and thus contributes to a longer inerting time.

As a result the fire will be extinguished as quickly as possible and you get better protection against re-ignition.

The extinguishing effect per unit of weight is in the range 3-10 times more effective than Halon and CO2.

Stixx Pro features low-temperature activation – why this is important for preventing fire outbreaks?

The low-temperature activation of the MAUS Stixx Pro is super important element of our system.

Our aim is to extinguish the fire as quickly as possible to avoid as much potential damage as possible.

This super low activation temperature and ability to put out the fire before it spreads and grows larger is especially imperative within environments such as server rooms and fuse boxes.

There is an incredibly high cost of damage if a fire is allowed to spread, not only within servers carrying important irreplaceable data, but the more a fire is allowed to grow, the higher the risk to life.

There are many benefits that come alongside the fire being put out as quickly as possible, the biggest being damage control.

Minimising parts needing to be replaced and reducing time taken to clean up results in areas being able to be back-up and operational incredibly quickly.

What sort of feedback have you received from customers or industry professionals?

We have recently been awarded a Highly Commended Product of the Year award at the IHEEM Healthcare estates 2024 show.

We were presented with this award as a result of our implementation throughout the NHS and our dedication to trying to further improve and develop fire extinguishing capabilities within all industries.

We have been receiving very positive feedback from large national infrastructure installations across the UK and Ireland, a couple of examples being Amazon, Pfizer and Irish Rail network.

What role do you see the Stixx Pro playing in improving public and workplace safety?

Stixx Pro will play the role of a ‘first responder’, our system improves public and workplace safety by being able to automatically react and extinguish fires before they spread.

The growing concern of fires starting when no one is around and being allowed to grow uncontrollably until only firefighters are able to extinguish.

Our system allows a maintenance free opportunity to control fires right at the start of ignition and eliminate the need for specialist firefighting techniques, therefore freeing up fire services availability for focus elsewhere.

We truly believe that the implementation of our system into domestic, commercial and industrial is imperative into the future of fire free environments.

Looking forward, how does MAUS plan to meet the evolving needs of fire safety in technological and electric spaces?

Achieving balance in foam performance with Perimeter Solutions

Mark Siem, Business Development Manager at Perimeter Solutions, explores the equipment updates and foam testing required for an effective fluorine-free foam transition

The fire safety industry is increasingly focused on sustainability, closely examining the environmental impact of firefighting methods and the tools that they use to protect lives and property.

This shift in mindset has driven forward-thinking fire departments, airports and other organizations that rely on firefighting foam to transition from traditional fluorinated foams, such as aqueous film-forming foam (AFFF) alcohol-resistant AFFFs and FluoroProtein foams, to fluorine-free alternatives, which offer a more sustainable solution.

However, before making the switch to synthetic fluorine-free foam (SFFF), organizations must consider several important factors and gain a clear understanding of the technical and logistical factors associated with the conversion in order to effectively navigate the transition.

Performance considerations

The transition to SFFF technology requires a multi-disciplinary discussion and decision between safety, engineering, environmental and purchase departments.

Once the decision is made to move to SFFF, one of the first things to consider is the type of fire hazards present at your location.

Do you deal with spill fires or fuel-in-depth fires? You must also identify which fuels you have on hand—hydrocarbon or polar solvent.

This will determine the type of fluorine-free foam that you need.

Both manual firefighting operations and fixed or semi-fixed foam systems must achieve proper application densities to be effective.

For manual firefighting operations, in most circumstances fluorine-free foam should be appropriate; however, additional considerations may need to be made to account for changes in viscosity or changes within application rates due to UL listing and/or FM Approval.

In hydrocarbon fire protection, fixed or semi-fixed foam systems may not need additional adjustments or changes, whereas with water miscible fires, in some cases adjustments to increase application rates may be required as per historically UL and FM provide guidance on the approved application rates.

Adjustments to proportioning equipment may also need to be taken into consideration to account for changes in viscosity and flow rates.

This would also present a good opportunity to reevaluate end-of-line discharge devices to ensure they align with current hazard needs and any updated changes in application rates associated with the selected product.

SFFF solutions used on water-miscible and polar solvent fuels have always been set to manufacturer recommendations.

With the transition to SFFF for Perimeter Solutions, the listings have remained the same for ethanol and methanol; however, potential increases in other water-miscible fuels may need to be reviewed.

In addition to flow rates and densities, foam quality plays a critical role in performance.

Foam quality parameters, including expansion ratio and drainage rate are crucial for effective fire protection.

Perimeter Solutions with its fluorine-free range has demonstrated and proven through approved and listed fire testing, we can successfully extinguish Class B fuel fires with non-aspirated discharge devices; however, wherever there is the option for aspirated regardless of fluorinated, or fluorine-free, that is always the preferred option.

Proportioning and discharge devices

For fixed or semi-fixed foam suppression systems and end-of-line discharge devices, a full review should be taken to ensure the application rates are still within the requirements and risk hazards of the facility.

In several cases, minimal or no changes may be required, or in some cases with the changes of hazards on site, proportioning devices and foam concentrate storage tanks may also need to be adjusted to accommodate the increased flow.

One of the key factors to consider is the viscosity of the firefighting foam, especially the distance between the foam concentrate and the ratio controller as longer distances can lead to friction loss.

This friction loss reduces the amount of foam entering the water stream resulting in a lower proportioning percentage.

Perimeter Solutions has continued to develop and move in to low-viscosity firefighting foams, reducing the need to increase pipe diameter to mitigate friction loss and for easy proportioning accurately.

If the system is a wet-pipe system, it may need to be converted to a deluge system to accommodate for pre-mixed foam solution stability.

It is also important to verify that the sprinkler have been listed or approved for use with the specific SFFF foam and fuel type by a third-party agency or relevant authority.

The benefit of using an UL or FM-approved system is that all components are designed to work together, ensuring optimal performance when all parts are properly integrated.

Key components include:

  • The tank
  • Foam concentrate
  • Ratio controller/proportioner
  • Discharge device

If an organization chooses to retain its existing fire safety equipment, it’s important to remember that the piping, discharge devices, etc., will need to be thoroughly cleaned or replaced before the transition.

Cleaning the equipment can be costly and even after cleaning, it may still contain residue.

In some cases, replacing the solution pipes is a more cost-effective solution.

Collaborating with industry peers facing similar challenges can provide valuable support during the transition.

It is also essential to stay updated on innovations in firefighting foam concentrates and equipment by attending workshops, presentations and other industry events.

Perimeter Solutions offers a Know Your Foam training session that is available at no cost to fire departments and other fire management agencies across the US and Canada.

The three-hour session includes in-class training and outside hands-on application of Class A and Class B foam.

Attendees at these sessions learn the difference between these foams, fluorine-free Class B foams, as well as emulsifiers and water.

Instructors demonstrate application techniques, including Roll On, Horizontal Spray, Bounce Off, Application then Reposition, Stitching and Tend the Blanket.

The session also covers the different types of foam systems, how to use a foam injection system and in-house maintenance of foam application products.

In the hand-on portion, participants will use a manual inductor, nozzles, foam tubes and foam injection systems.

Additional considerations

When transitioning to SFFF, there are additional considerations involving equipment that may need to be addressed for smooth and effective implementation of the new technology:

Testing and commissioning equipment

After cleaning and disposing of fluorinated foam, the next step is to test and commission equipment with the new SFFF solution.

Internal testing is commonly conducted by flowing foam concentrate through the system, pulling a sample and comparing it against a calibration curve.

If the sample falls within the proper range of the curve, the system is confirmed to be working correctly.

This ensures that your equipment is properly integrated with the new foam and any issues are identified early.

Foam quality checks

Once the equipment is in place, it is vital to assess the foam quality coming out of discharge devices.

Key performance indicators such as expansion ratio and drainage rate should be evaluated to ensure they align with the manufacturer’s recommendations.

Checking foam quality helps confirm that the equipment is delivering the correct performance to suppress fires effectively.

Budgeting for the transition

The costs associated with transitioning to SFFF outlined above can add up quickly.

Perimeter Solutions has been able to retrofit existing systems, in some cases with minimal changes; however, consideration needs to be made to foam proportioners, storage tanks and discharge devices to accommodate SFFF.

These additional expenses should be considered when planning the transition and budgeting for the necessary equipment and foam supplies.

Regarding storage of SFFF concentrate, there isn’t a noticeable difference compared to fluorinated firefighting foams.

When stored in original containers, or in tanks designed for foam storage with manufacturer-recommended equipment and within the specified temperature range, a shelf-life of at least 10 years is expected and is projected to be approximately 15-20 years.

(Shelf life studies are ongoing to ensure quality and further storage longevity).

Advanced SFFF options available now

Perimeter Solutions offers a comprehensive line of fluorine-free foam concentrates.

Our SOLBERG VERSAGARD 1×3 Multipurpose Fluorine-Free Foam Concentrate meets the most demanding emergency response applications and is UL 162 listed and GreenScreen Certified Silver® as well as multiple international certifications, including LASTFIRE.

It has been tested and designed for industrial emergency response and is ideal for facilities that store crude oil on site.

SOLBERG RE-HEALING 3×3 SP-100 was the industry’s first UL-listed fluorine-free 3×3 foam concentrate with the full complement of hardware and sprinkler listings, including non-aspirated, standard sprinkler heads.

FM-approved, it is used in sprinkler applications to extinguish and secure both Class B hydrocarbon and polar solvent fuels.

Our PHOS-CHEK® 1% Fluorine-Free Class A/B Foam Concentrate was the industry’s first certified fluorine-free Class A/B foam concentrate on the market.

A versatile solution, it can be used to help extinguish structural, residential, wildland, petroleum and other fires.

While the shift to SFFF technology offers significant benefits, such as reducing the impact on ecosystems and human health, it requires careful consideration of performance, equipment and budget.

By thoroughly testing equipment, ensuring foam quality and planning for necessary upgrades, organizations can successfully make the switch.

As the industry continues the transition to SFFF, staying informed and working closely with trusted companies like Perimeter Solutions can help streamline the process.

The phase-out of PFAS in firefighting: Britannia Fire explores what it means for fire safety standards

Andy Spence, Joint Managing Director of Britannia Fire, discusses the industry’s shift to sustainable fire safety, including composite extinguishers and PFAS-free alternatives

Innovations in fire extinguisher design and technology mean we now have greener alternatives that considerably reduce carbon emissions and improve sustainability.

Easier to maintain, they also provide long term cost-savings for the customer.

So why has the fire protection industry been slow to embrace this change?

Fire extinguishers play a vital role in fire protection.

They are essential for suppressing fire in its early stages and can help to prevent catastrophic damage and harm.

But there is so much more we can do as an industry to make their manufacture, supply and maintenance more environmentally friendly.

The sector has been slow to change course but is waking up to the fact that change is inevitable and that viable solutions are now readily available.

The future is composite

Traditional, steel fire extinguishers last around 10 years, but are prone to corrosion and must be serviced annually to ensure they remain fit for purpose.

We first started manufacturing steel fire extinguishers at our Britannia Fire factory in Norfolk back in 1970 and built a highly successful and respected brand around these early models and successive versions.

But by embracing the introduction of new materials and technology, our founder Roger Carr, saw an opportunity to create a new model out of composite material that would be corrosion resistant and lightweight, with no annual service required.

Launched in 2010, the P50 was the first composite fire extinguisher of its kind and has since been sold around the globe, with demand continuing to outstrip supply.

Last year, we took the significant step to discontinue the production of our original metal ranges altogether to focus solely on increasing supply of our P50 range.

It’s a superior product which provides a win-win for the customer and the environment.

Thanks to their anti-corrosion properties, composite fire extinguishers like the P50 can last 20 years: typically twice as long as metal varieties.

They don’t need to be serviced by a technician every year.

Instead, they just need simple, regular checks from a designated competent person, which can be done with the help of our dedicated App.

After 10 years, factory refurbishment will extend the life of a P50 for another 10 years.

As well as saving time and money on annual services and replacements, these extinguishers are much better for the environment, with a reduction in wastage and in carbon emissions around servicing.

Despite these innovations and the success of the P50, it’s still the case that the vast majority of fire extinguishers currently in use across the UK and Europe are traditional metal designs.

Most will have been manufactured in China and shipped thousands of miles before reaching the customer.

They are sold cheaply but on annual servicing contracts, which bring in an attractive revenue many suppliers are reluctant to give up.

An end to PFAS chemicals

AFFF fire extinguishers containing PFAS are the most common type of foam extinguishers.

These harmful ‘forever chemicals’ don’t break down in the environment, can disrupt biological processes and are toxic to some species.

Measures are being taken across the globe to reduce, restrict and phase out the use of PFAS, such as the UN’s Stockholm Convention, which is a global treaty to protect human health and the environment from persistent organic pollutants.

Europe is taking the most progressive approach to regulation with a ban on firefighting foams containing PFAS due to come into force by 2030 and the UK is expected to follow this lead.

Britannia Fire is proud to be leading the way in championing environmentally friendly fire safety products.

In 2023, we launched our PFAS-free foam P50 model, which works effectively without the use of harmful fluoro chemicals.

Many companies and organisations are ahead of the game and choosing PFAS free models to help reduce their environmental impact.

UK government regulation is anticipated later this year, which will prohibit the manufacture and sale of fire extinguishers containing PFAS.

This is absolutely the right course of action, ensuring that as an industry we are all playing our part in supplying and promoting more sustainable products.

Multi-use extinguishers

Recent technologies and innovation have also helped to simplify the various types of fire extinguishers required and their applications.

This reduces the number of fire extinguishers required in certain locations, with a positive impact on both the environment and the customer’s bottom line.

Historically, customers would be required to install a combination of water-based, dry powder, or CO2 fire extinguishers depending on whether a fire in that location is likely to involve wood and textiles, electrical equipment or cooking oils.

Frequently, two or more models were installed side by side, with instructions for the user on which to operate.

Thankfully, a number of multipurpose options are now available, making installation and use much more straightforward.

Our P50 Water Mist extinguisher is safe to use on carbonaceous (Class A) fires, as well as electrical fires, so it’s perfect for offices, hotels, shops, churches and rental properties, for example.

It contains de-ionised water, which means it leaves almost no residue after use.

Our P50 PFAS-Free Foam model goes even further, extinguishing Class A (carbonaceous) fires, Class B (flammable liquids) fires, Class F (fats and oils) and has also passed the EN3 test for use on live electrical equipment up to 1000V.

This is suitable for garages, farms, chemical storage and large event venues, for example.

Heathrow Airport recently replaced its multiple sets of two extinguishers with P50 Foam multi-purpose units as part of its sustainability strategy.

These have saved the airport more than £1m and will need minimal servicing for a decade.

Providing one multi-purpose option is also much more user-friendly, particularly in a busy airport with worldwide travellers speaking many different languages!

Despite these innovations, too many companies and organisations are still wasting time and money on unnecessary annual servicing and multiple units.

Some guidelines, even those issued by the British Standards Institute, have been slow to keep pace with innovations and still recommend outdated servicing practices.

However, we can assure our customers that Britannia Fire P50 extinguishers conform to Pressure Equipment Regulations and European standards, they are BS EN3-7 certified and have a BSI Kitemark to show they are safe and legal to use in the UK.

Responsible disposal

At Britannia Fire, we’ve always taken our environmental responsibilities seriously and are committed to doing all we can to minimise our carbon footprint, including investing in solar panels for our production plants as part of our mission to achieve carbon net zero manufacturing.

We’re also committed to helping our customers with their own sustainability targets.

Our P50 composite range is easily recyclable.

Part of our offer also includes a recycling and scrappage service, helping customers dispose of their obsolete metal and PFAS-containing extinguishers in a responsible way.

We take the old units off their hands and recycle what we can, disposing of the remainder responsibly.

Encouraging change

Clearly, it’s time for the industry to fully embrace innovations that can make the fire extinguisher market more sustainable. PFAS regulations will help expediate this.

In addition, we need to raise awareness amongst those responsible for fire safety, providing them with the right training, tools and guidance to source the most suitable equipment for their fire safety needs whilst minimising impact on the environment.
