Bin Lorry Fires & Lithium Batteries: Could Firesleeve Protect Critical Components?

Thu, 01 Oct 2026 13:49:20 GMT

Lithium batteries: a growing fire risk for refuse vehicles

Lithium-ion batteries have become part of everyday life. They are found in mobile phones, vapes, power banks, rechargeable tools, toys, e-bikes, electrical equipment and countless other products.

But when batteries are incorrectly placed into household waste, they can create a serious and increasingly visible problem for the waste and recycling industry.

Once inside a refuse collection vehicle, batteries can be crushed or damaged during the collection and compaction process. In the wrong circumstances, this can result in smoke, ignition and fire.

For refuse vehicle operators, the consequences can extend well beyond the immediate fire itself. A vehicle may need to be taken out of service, critical hydraulic or electrical components can be exposed to intense heat, and an incident can result in significant vehicle damage, operational disruption and cost.

So, while preventing batteries from entering the general waste stream remains essential, could additional heat protection around critical vehicle components provide another layer of protection if a fire does occur?

This is where firesleeve has an interesting role to play.

Lithium batteries: a growing fire risk for refuse vehicles

Lithium-ion batteries should not be placed in ordinary household waste or recycling collections.

When batteries are damaged, crushed or short-circuited, they can enter thermal runaway and release significant heat. Within a refuse collection vehicle, the compaction process can create exactly the type of mechanical damage that may turn an incorrectly discarded battery into a fire hazard.

Recent incidents demonstrate that this is not simply a theoretical risk:

In July 2026, Herefordshire Council reported a bin lorry fire caused by a lithium battery that had been incorrectly disposed of in household waste. The collection crew spotted the fire and were able to safely empty the vehicle before Hereford & Worcester Fire and Rescue Service extinguished the fire.

In the same month, St Albans City and District Council reported an incident in which a battery discarded in household waste caused smoke to emerge from a 26-tonne refuse vehicle. The crew safely ejected the smouldering waste onto the road while the Fire Service attended.

More recently, in September 2026, Cumberland Council reported an incident involving an e-bike battery discovered inside a refuse vehicle. The battery began to smoke and hiss, prompting the crew to act quickly. Almost 10 tonnes of waste subsequently had to be emptied and checked to ensure the battery had not caused a fire to spread.

These incidents highlight an important point.

The waste itself may be the source of the fire, but the vehicle contains critical systems that still need to function during the emergency.

The scale of bin lorry fires

This is not an isolated problem affecting a handful of vehicles.

The Environmental Services Association (ESA) reported 216 battery-related fires in bin lorries in the year to March 2026 , alongside 1,518 fires reported across its members' waste and recycling operations, as reported in The Guardian .

SUEZ has highlighted a Material Focus/National Fire Chiefs Council estimate of more than 1,200 battery-related fires each year across UK bin lorries and waste facilities . ( suez.co.uk )

The precise number is difficult to establish because the source of every waste fire cannot always be determined.

What is clear is that lithium batteries are now recognised as a significant fire risk across waste collection, recycling and treatment operations.

And for refuse vehicles, the consequences can be particularly expensive.

In January 2026, North Warwickshire Borough Council reported a serious fire caused by a lithium battery in a household bin. The refuse vehicle was permanently damaged and no longer safe for use on the road .

The council estimated that replacing the refuse vehicle would cost approximately £250,000 , while repair of the rear section could cost around £125,000 . ( northwarks.gov.uk )

Just two months later, North Warwickshire reported another bin-lorry fire — its third in four months .

On that occasion, the council stated that refuse vehicles cost approximately £300,000 , while hiring a temporary replacement vehicle cost around £1,000 per week . It also noted that some vehicles may be written off entirely following fire damage. ( northwarks.gov.uk )

What happens when a fire develops inside a bin lorry?

Modern refuse collection vehicles rely on hydraulic , electrical and mechanical systems to operate the collection and compaction equipment.

Hydraulic hoses, electrical cables, wiring and pipework may run around or close to areas where a fire could potentially develop.

If these components are exposed to intense heat or direct flame, their integrity can be compromised.

Damage to a hydraulic hose, for example, could result in loss of hydraulic pressure and potentially prevent equipment from operating . Damage to electrical wiring or control systems could similarly affect the vehicle or its ability to operate safely.

This raises an interesting engineering question:

Could firesleeve protect critical components during a bin lorry fire?

Firesleeve cannot prevent a lithium battery from igniting.

It cannot make a refuse collection vehicle fireproof.

And it should never be regarded as a replacement for appropriate fire detection, emergency procedures, vehicle design or safe battery disposal.

Its potential role is different.

Pyrosleeve’s Firesleeve provides a physical thermal barrier around vulnerable hoses, cables and other components. By adding heat and flame protection at identified risk points, its purpose is to reduce the rate of heat transfer to the protected component, potentially delaying heat-related damage.

What is firesleeve?

Firesleeve is a flexible high-temperature protective sleeve designed to shield hoses, cables, wires, hydraulic lines, fuel systems and pipework from demanding thermal environments.

Pyrosleeve silicone-coated firesleeve combines a knitted, texturised E-glass fibre sleeve with a high-grade silicone elastomer coating.

The knitted E-glass construction provides the thermal barrier, while the silicone elastomer coating provides protection against flame, abrasion, moisture, oils, hydraulic fluids, fuels and other demanding environmental conditions.

For applications where components could be exposed to a combination of heat, flame, mechanical abrasion and fluids, this combination can offer advantages over an uncoated insulating sleeve.

Pyrosleeve's standard silicone-coated firesleeve is rated for continuous operating temperatures of up to 260°C, with resistance to intermittent molten-metal splash at temperatures up to 1,200°C. (Actual performance in any application depends on the complete installation, heat source, exposure duration and other environmental factors, so product specifications should always be considered alongside the specific application).

Could firesleeve help protect a refuse vehicle during a fire?

The answer depends on the vehicle, the location of the fire and the components being protected. There is no single firesleeve installation that will suit every refuse collection vehicle.

Instead, the potential application is to identify critical components where additional thermal protection could be beneficial .

These could include:

Hydraulic hoses & lines
Electrical cables & wiring harnesses
Control cables
Fuel or fluid lines where appropriate
Other vulnerable components identified through vehicle risk assessment

The objective is not to protect every component on the vehicle.

It is to consider whether protecting strategically important components could help maintain their integrity for longer when exposed to an unexpected heat source.

The difference between preventing a fire and protecting against its consequences

This distinction is important.

The first priority must always be fire prevention .

That means encouraging correct battery disposal, improving public awareness, identifying battery-related hazards and ensuring refuse collection crews have appropriate procedures for dealing with suspected fires.

But accidents and incorrectly disposed batteries cannot always be eliminated.

A second layer of protection can therefore be worth considering.

For vehicle manufacturers and fleet operators, this could mean identifying components where heat exposure could have particularly serious consequences and asking whether additional thermal protection should form part of the vehicle's design or maintenance strategy.

Hook & Loop firesleeve: a potential retrofit solution for bin trucks

One of the challenges with existing refuse vehicles is that hoses, cables and pipework are already installed .

Removing a hydraulic hose or disconnecting a cable simply to install conventional tubular sleeving may be impractical, time-consuming or undesirable.

This is where Hook & Loop firesleeve can provide a practical retrofit option.

Pyrosleeve's PGH.20/ROS/VC is a silicone-coated glass fibre firesleeve incorporating a flame-retardant hook & loop closure. The sleeve can be opened along its length and fitted around an existing hose, pipe or cable assembly without requiring the component to be disconnected.

This makes hook & loop firesleeve particularly relevant when considering retrofit protection for existing refuse collection vehicles .

It can potentially be used to protect existing hose and cable assemblies in areas identified as being particularly exposed to heat.

The closure also allows the sleeve to be removed when required for inspection or maintenance.

For fleet operators managing multiple vehicle types, bespoke dimensions and made-to-length assemblies can also be considered.

Retrofitting existing refuse vehicle fleets with firesleeve

For a local authority or waste management company, replacing a complete vehicle following a serious fire can represent a significant operational and financial disruption.

This makes retrofit protection an interesting area for consideration.

A fleet engineering assessment could identify:

Where hydraulic hoses and electrical systems are routed around the vehicle.
Which components are closest to the refuse body or other potential heat sources.
Which components are considered critical to safe vehicle operation.
Which areas could benefit from additional heat or flame protection.
Whether conventional firesleeve or a removable hook & loop configuration is most appropriate.

The intention would not be to assume that firesleeve will prevent vehicle damage.

Instead, it is about asking a practical engineering question:

Could additional thermal protection help delay damage to critical components long enough to support the safe management of a vehicle fire?

Firesleeve for refuse vehicle manufacturers

The same principle can be considered much earlier in the design process.

For refuse vehicle manufacturers and body builders, thermal protection can potentially be incorporated into the design around identified vulnerable areas rather than added later as a retrofit.

Pyrosleeve can manufacture standard and bespoke firesleeve configurations, including custom diameters, made-to-length assemblies, production kits and hook & loop retrofit solutions.

This gives OEMs the opportunity to consider thermal protection as part of the overall vehicle design.

For example, a manufacturer could identify specific hydraulic hose routes or electrical harnesses that could be exposed to elevated temperatures and assess whether a suitable firesleeve configuration should be incorporated during vehicle build.

Beyond battery disposal: protecting critical vehicle systems

The message around lithium batteries is rightly focused on prevention .

Residents need to understand that batteries should never simply be thrown into household waste or recycling bins.

However, waste collection vehicles operate in the real world, and incorrectly disposed batteries will continue to enter waste streams.

Recent UK incidents show the value of rapid detection and effective crew response. In several cases, crews have identified smoke or fire and discharged the waste before the situation became more serious.

That creates a short but potentially important window in which the vehicle, its crew and the surrounding public need to be protected.

Protecting critical hydraulic and electrical components cannot remove the fire risk.

But it could form part of a wider approach to protecting the vehicle's critical systems against heat exposure .

Could firesleeve help buy valuable time in bin lorry fires?

A refuse vehicle fire can develop rapidly and the ability to discharge the load, isolate the vehicle and allow emergency services to deal with the incident safely is critical .

Firesleeve is not a fire suppression system.

It is not a guarantee that a vehicle will survive a fire.

What it can provide is a flexible thermal barrier around selected components .

For refuse vehicle manufacturers, body builders, fleet operators and local authorities, that makes firesleeve an engineering solution worth investigating as part of a wider vehicle fire-risk strategy.

Frequently Asked Questions

Can firesleeve prevent a bin lorry fire?

No. Firesleeve cannot prevent a lithium-ion battery from entering thermal runaway or extinguish a vehicle fire. Its potential role is to provide additional thermal protection around selected hydraulic, electrical or other critical components.

Can firesleeve protect hydraulic hoses on refuse vehicles?
Potentially, depending on the hose location, heat source, exposure duration and installation. Firesleeve is designed to provide thermal and flame protection around hydraulic hoses and other assemblies.

Can firesleeve be fitted to an existing bin lorry?
Yes. Hook & Loop firesleeve can be installed around existing hoses, cables and pipework without disconnecting the assembly, making it suitable for retrofit applications. Pyrosleeve specifically identifies its PGH.20/ROS/VC as a retrofit solution.

Our Firesleeve (PGH.20/ROS) achieves UL 94 V-0 Flame Rating: What Does It Mean?

Fri, 21 Aug 2026 11:58:57 GMT

UL 94 Vertical Flame Testing

of our Firesleeve:

What this means: Pyrosleeve's Firesleeve ( PGH.20/ROS ) has achieved the highest classification within the UL 94 V-0, V-1 and V-2 vertical burning system, with no recorded afterflame following either flame application during independent flame-resistant performance testing of our silicone coated glass fibre firesleeves .

In August 2026, we commissioned Impact Solutions to carry out UL-94 vertical orientation flammability testing on our firesleeve (PGH.20/ROS).

The result? Pyrosleeve's Firesleeve achieved a V-0 classification , the highest classification within the UL-94 V-0, V-1 and V-2 vertical burning system.

Even more notably, the five specimens tested recorded a total afterflame time of 0 seconds . None of the specimens produced flaming drips and none burned up to the specimen clamp.

But what does UL 94 V-0 actually mean, and why is it important when choosing a firesleeve?

What is UL 94 flame testing?

UL 94 is a recognised flammability testing standard used to assess how a material behaves when exposed to a controlled flame.

Its full title is: "Test for Flammability of Plastic Materials for Parts in Devices and Appliances"

In simple terms, the test looks at whether a material continues to burn after a flame is applied and removed. It also looks at:

how quickly the material stops burning
whether it continues to glow
whether burning material drips from the specimen
whether flames travel up the specimen

For our test, Impact Solutions carried out a 50W Vertical Flame Test in accordance with UL 94 Paragraph 8.

The specimens were positioned vertically and exposed to a controlled methane flame for 10 seconds. The flame was then removed, and the 'afterflame' and 'afterglow' behaviour was recorded. The flame was subsequently reapplied for a further 10 seconds and the process repeated.

What does UL 94 V-0 mean?

The UL 94 standard includes several classifications for vertical burning performance, including:

V-0 <-- the highest of these 3 classifications.
V-1
V-2

To achieve V-0, individual specimens must have an afterflame time of no more than 10 seconds, while the total afterflame time for the five specimens must not exceed 50 seconds.

The material must also:

Not continue burning or glowing up to the holding clamp
Not produce flaming particles or drops that ignite the cotton indicator below
Meet the specified combined afterflame and afterglow time requirements (see table below)

In plain English...

A V-0 result means the material stops flaming very quickly when the flame source is removed and does not produce flaming drips that could ignite material underneath.

That is particularly relevant for applications where materials are installed close to cables, hoses, pipework or other components where uncontrolled flame spread or burning droplets could present an additional hazard.

What happened when Pyrosleeve's Firesleeve was tested?

The results from our firesleeve tests were very positive.

5 x Firesleeve specimens were tested and the results were:

Total afterflame time was: 0 seconds
No afterflame following either flame application

The laboratory also reported that none of our specimens showed signs of ignition while the flame was being applied. Following flame removal, there was only a limited cherry-red afterglow at the bottom of the material, together with a small amount of smoke ring production.

Importantly, none of the specimens produced flaming drips and none burned up to the specimen clamp.

The individual test results were:

The laboratory recorded a total afterflame time of 0 seconds , resulting in the final classification of V-0 .

Standard UL 94: 'V-0' vs 'V-1' vs 'V-2'

So, what is the difference between the three classifications of UL 94?

The V-0 classification therefore represents the most demanding of these three vertical burning classifications.

Why is UL 94 V-0 important for firesleeve?

Firesleeve is used to provide thermal and flame protection around components such as hydraulic hoses, fuel lines, cables, wiring and pipework installed into critical systems where components may be exposed to elevated temperatures or potential flame hazards.

Industries include:

Railways & rolling stock
Underground transport systems
Mining
Heavy-duty vehicles
Industrial machinery
Power generation
Marine applications
Fire suppression systems
Intelligent Robot Industries

When selecting a protective sleeve for a demanding application, engineers need to consider more than simply the maximum operating temperature. How a material behaves when exposed to flame is also a very important consideration, particularly where sleeving is installed close to heat-producing components.

A UL 94 V-0 result provides useful additional information about the flammability behaviour of the tested Firesleeve construction. For applications where flame resistance and protection from heat are important design considerations, this additional test data can help engineers make a more informed material selection.

Is UL 94 V-0 the same as a 250°C temperature rating?

No - and this is an important distinction!

UL 94 V-0 is a flammability classification , not a continuous operating temperature rating.

Our firesleeve has a stated continuous operating temperature of up to 250°C, while its UL 94 V-0 result relates specifically to its behaviour during the controlled vertical flame test.

These are two different characteristics and should not be confused.

The UL 94 test also does not by itself determine the complete fire performance or suitability of a product for every application. The laboratory report specifically notes that the results relate to the behaviour of the test specimens under the conditions of the test and should not be used as the sole criterion for assessing potential fire hazard in service.

How was Pyrosleeve tested?

The testing was carried out by Impact Solutions on Pyrosleeve PGH.20/ROS, with a nominal specimen thickness of 5.0 mm.

The specimens were prepared to the required dimensions and conditioned at 23 ± 2°C and 50 ± 5% relative humidity for at least 48 hours before testing.

During the test, specimens were mounted vertically and exposed to a controlled 50W methane flame. The flame was applied to the bottom edge of each specimen for 10 seconds, removed, and then reapplied for a further 10 seconds. Afterflame, afterglow, flame spread and flaming drips were recorded.

The testing was performed under UL 94:2014 , Paragraph 8. The report identifies the 50W Vertical Flame Test as a non-UKAS test within the laboratory's report.

What does this mean for Pyrosleeve customers?

The V-0 result gives customers and engineers another piece of independently generated test data when evaluating Pyrosleeve's Firesleeve for demanding applications.

Combined with the product's silicone-coated glass fibre construction and thermal protection capabilities, the result demonstrates the importance we place on testing , quality and continual product development .

We believe engineers should be able to specify protective textile products with confidence — supported by clear, meaningful technical information rather than simply relying on marketing claims.

Frequently Asked Questions

What is a UL 94 V-0 rating?

UL 94 V-0 is the highest classification within the V-0, V-1 and V-2 vertical burning classification system. It indicates that the tested material meets stringent requirements for afterflame and afterglow behaviour and does not produce flaming drips during the test.

Is V-0 the highest UL 94 rating?

YES

V-0 is the highest classification among the UL 94 vertical V-0, V-1 and V-2 classifications. Other UL 94 classifications and test methods exist, so it is more accurate to describe V-0 specifically as the highest of these three vertical classifications.

Did Pyrosleeve pass the UL 94 test?

YES - Our Firesleeve (PGH.20/ROS) achieved a V-0 classification during the UL-94 vertical orientation flammability test carried out by Impact Solutions in August 2026.

What was Pyrosleeve's afterflame time?

The five specimens recorded a total afterflame time of 0 seconds. Each specimen recorded 0 seconds after the first and second flame applications.

Did Pyrosleeve produce flaming drips?

NO - none of the five specimens produced flaming drips during the UL 94 test. None of the specimens burned up to the holding clamp.

Does UL 94 V-0 mean Pyrosleeve can operate continuously at a particular temperature?

NO - UL 94 V-0 is a flammability classification and should not be interpreted as a continuous operating temperature rating. Temperature performance and flame performance are separate characteristics.

Test results relate to the specimens tested under the conditions of the laboratory test. They should not be considered the sole criterion for assessing fire hazard or suitability for a particular application.

How Long Does Firesleeve Last ?

Fri, 24 Jul 2026 10:49:16 GMT

A Technical Guide to Service Life, Inspection & Replacement

How Long Does Firesleeve Last?

When protecting hydraulic hoses, fuel lines, electrical cables and industrial pipework from extreme temperatures, firesleeve is often expected to perform reliably for many years with little maintenance. However, one of the most common questions engineers, maintenance teams and procurement specialists ask is:

"How long should firesleeve last?"

The honest answer is that there is no fixed lifespan.

Unlike components with predetermined replacement intervals, the service life of a high-quality silicone-coated glass fibre firesleeve depends on numerous factors including operating temperature, environmental conditions, mechanical wear, chemical exposure and installation quality.

In controlled industrial environments, premium firesleeve may remain fully serviceable for many years. In harsher environments involving molten metal splash, continuous abrasion, hydraulic oil contamination or outdoor UV exposure, inspections should be carried out more frequently and replacement may be required sooner.

Understanding what influences firesleeve longevity helps maximise equipment protection, reduce unplanned downtime and improve maintenance planning.

What Determines the Service Life of Firesleeve?

Several interacting factors influence how long firesleeve continues to provide effective thermal protection.

Operating Temperature

Temperature is naturally the biggest influence.

A quality silicone-coated E-glass firesleeve is typically designed for:

Continuous operating temperatures around 260°C
Short-duration exposure to significantly higher temperatures
Protection from molten metal splash approaching 1,200°C

Continuous operation close to maximum design temperatures accelerates ageing of the silicone elastomer coating.

The glass fibre insulation itself remains stable at temperatures beyond the limits of the silicone coating, but repeated thermal cycling gradually hardens elastomers over time.

Lower operating temperatures generally result in substantially longer service life.

Thermal Cycling

Many industrial systems repeatedly heat and cool throughout the working day.

This repeated expansion and contraction creates stresses within the silicone coating, with thousands of heating and cooling cycles over several years can eventually lead to:

surface hardening
reduced flexibility
minor cracking
loss of elasticity

This ageing process is gradual and should be monitored during routine inspections.

Mechanical Abrasion

In many applications, abrasion causes premature replacement long before heat damage occurs.

Typical sources include:

vibrating hydraulic hoses
rubbing against brackets
cable movement
hose clamps
engine vibration
moving machinery

Silicone coatings provide excellent abrasion resistance, but no protective sleeve is immune to continuous mechanical wear. Proper routing and adequate support significantly extends service life.

Chemical Exposure

Industrial environments often expose firesleeve to:

hydraulic fluids
lubricating oils
diesel fuel
petrol
coolants
cleaning chemicals
dilute acids
alkalis

High-quality silicone elastomers offer excellent resistance to many industrial fluids. However, prolonged immersion or exposure to aggressive chemicals beyond the material's design limits can accelerate degradation.

Always verify chemical compatibility for specialist applications.

Ultraviolet (UV) Exposure

Outdoor equipment presents different challenges. Over extended periods UV radiation slowly ages most elastomeric materials. Although silicone performs significantly better than many synthetic rubbers, long-term outdoor installations should still form part of scheduled inspection programmes .

Installation Quality

Incorrect installation remains one of the leading causes of premature failure. Common mistakes include:

stretching the sleeve excessively
forcing it over oversized fittings
insufficient clearance around bends
poor end finishing
inadequate clamping where required

Correct installation minimises unnecessary mechanical stresses throughout the product's life.

Common Failure Modes of Firesleeve:

A well-manufactured firesleeve rarely fails without visible warning signs. Understanding typical failure mechanisms allows replacement before protection is compromised. Common failure modes include:

Torn Glass Fibre

Mechanical damage can eventually penetrate through the silicone coating into the knitted glass fibre substrate. This significantly reduces thermal protection and should normally trigger replacement.

Localised Heat Damage

Exceptional overheating may produce:

blistering
charring
burnt silicone
local hardening

These indicate temperatures have exceeded the intended operating conditions.

Contamination

Heavy deposits of:

oil
carbon
welding debris
molten metal residue

may conceal damage during inspections. Cleaning before assessment is recommended where practical.

How Often Should Firesleeve Be Inspected?

Inspection frequency depends on the application's operating environment. As a general guide:

Where equipment is considered safety-critical, inspections should always follow the machinery manufacturer's maintenance schedule.

What Should You Look For During Inspection?

Maintenance personnel should inspect for:

✔ Cuts

✔ Tears

✔ Abrasion

✔ Missing silicone

✔ Burn marks

✔ Brittle coating

✔ Oil saturation

✔ Loose securing methods

✔ Heat discolouration

✔ Exposed glass fibre

If any of these conditions are observed, further assessment should be carried out before returning equipment to service.

Does Firesleeve Wear Out Suddenly?

Generally, no.

Unlike some protective products that fail catastrophically, quality firesleeve normally deteriorates gradually.

This progressive ageing provides maintenance teams with opportunities to identify deterioration during routine inspections before thermal protection is significantly compromised.

Can Firesleeve Be Reused?

Where firesleeve has been carefully removed without damage and remains in excellent condition, reuse may be technically possible in some non-critical applications. However, in safety-critical environments it is generally recommended that damaged or heavily aged firesleeve is replaced rather than reused. Replacing worn firesleeve is usually inexpensive compared with the potential cost of hose failure, equipment damage or unplanned downtime.

Does Manufacturing Quality Affect Service Life?

Absolutely! Not all firesleeves are manufactured to the same standards.

Factors that influence long-term durability include:

Glass fibre yarn quality
Braid or knit consistency
Silicone formulation
Coating thickness
Curing process
Dimensional accuracy
Quality control
Batch traceability

Consistent manufacturing processes help ensure that every production batch delivers predictable thermal performance and mechanical durability. For engineers specifying firesleeve, selecting a manufacturer with established UKAS accredited quality systems and robust process controls can provide greater confidence in long-term performance.

Maximising Firesleeve Service Life

The following practices can help extend operational life:

Select the correct diameter for the application.
Avoid excessive stretching during installation.
Prevent continuous rubbing against sharp edges.
Support hoses and cables correctly.
Inspect regularly as part of planned maintenance.
Replace damaged sections promptly.
Use products appropriate for the operating temperature and environment.
Source firesleeve from manufacturers with consistent quality control.

Frequently Asked Questions

Is firesleeve a consumable product?

Not in the traditional sense. Firesleeve is designed as a durable protective component, but like any engineering material it will gradually age in service and should be inspected periodically.

Can firesleeve last 10 years?

In stable industrial environments with moderate temperatures and minimal abrasion, high-quality firesleeve can remain serviceable for many years. Actual service life depends on operating conditions and maintenance.

What causes firesleeve to fail?

The most common causes are mechanical abrasion, excessive heat, incorrect installation, chemical attack and prolonged ageing.

Should damaged firesleeve be repaired?

Minor external contamination may be cleaned, but firesleeve with exposed glass fibre, significant abrasion or heat damage is generally best replaced.

Does thicker silicone mean longer life?

Not necessarily. Durability depends on the overall design, material quality, coating formulation, curing process and manufacturing consistency—not just coating thickness.

Conclusion

There is no universal service life for firesleeve because every application places different demands on the material. The key to achieving long-term performance lies in selecting a high-quality product, installing it correctly and carrying out regular inspections as part of a preventative maintenance programme.

By understanding the factors that influence ageing—including temperature, abrasion, thermal cycling and environmental exposure—engineers can make informed decisions that maximise protection and minimise downtime.

What is BS EN 45545-2:2020+A1:2023?

Wed, 24 Jun 2026 12:50:42 GMT

The European "Gold Standard" for

Railway Fire Safety

When a product is tested to EN 45545-2:2020 , it means it has passed one of the most stringent fire safety standards in the European railway industry.

This certification ensures that materials used in railway and underground transport systems are designed to resist fire, minimise flame spread, reduce smoke generation and limit the release of toxic gases in the event of a fire.

For railway operators, manufacturers and infrastructure providers, compliance with EN 45545-2:2020 is essential for protecting passengers, staff and critical systems in high-risk transport environments.

What Is EN 45545-2:2020?

EN 45545-2:2020 is the European standard that defines fire safety requirements for materials and components used in railway vehicles. The standard evaluates how products behave under fire conditions, specifically focusing on:

1. Flame Spread - Assesses how quickly a material ignites and burns.

Test Standard: EN ISO 4589-2

2. Smoke Density - Measures how much smoke is produced & how severely visibility is reduced during a fire.

Test Standard: ISO 5659-2

3. Toxicity - Determines whether smoke emissions contain dangerous or potentially lethal gases such as carbon monoxide or hydrogen cyanide.

Test Standard: BS EN 17084:2018

Together, these tests ensure passengers have more time to safely evacuate railway vehicles and tunnels during a fire emergency.

The importance of EN 45545-2:2020

EN 45545-2 harmonises railway fire safety regulations across Europe and is widely recognised as the benchmark standard for rail vehicle fire protection.

The standard is critical because it sets strict performance requirements for:

Flame spread control
Heat release reduction
Smoke suppression
Toxic gas emission control

In confined environments such as railway carriages, underground tunnels and metro systems, these factors are vital for passenger safety and emergency evacuation.

Fire Risks in Rail and Underground Environments

Rail and underground transport systems operate in enclosed spaces where heat, vibration and limited ventilation can rapidly escalate fire risks.

Common fire hazards within railway infrastructure include:

Electrical cables exposed to abrasion, vibration, and high engine temperatures
Hydraulic and fuel lines routed near hot engines and braking systems
Poor ventilation in tunnels and underground routes
Sparks generated from braking, grinding, and maintenance operations

Without adequate protection, hoses, cables and wiring can become ignition points that compromise critical systems and passenger safety.

This is why fire protection products such as Firesleeve are essential within railway applications.

Where Is Firesleeve Used in Railway Vehicles?

Firesleeve is installed over hydraulic hoses, electrical harnesses and fuel lines to provide protection against:

Extreme heat
Flame exposure
Abrasion damage
Mechanical wear

By protecting critical systems, Firesleeve helps reduce the likelihood of fire caused by damaged cables or fluid lines.

Common Applications for Firesleeve in railways:

Firesleeves are widely used in:

Underground transport rolling stock
Locomotive engine compartments
Metro and subway infrastructure
Hydraulic and pneumatic braking systems
Electrical wiring near heat-emitting equipment
Emergency lighting systems
Fire suppression system components
Critical evacuation route infrastructure

What Does “HL3 Rated Under R22” Mean?

If a product is classified as HL3 rated under R22 , it has achieved the highest hazard level classification under EN 45545-2.

HL3 certification is required for the most demanding railway environments, including:

Underground metro systems
Sleeper trains
Long tunnel operations
High-capacity passenger rail systems

These applications present increased fire risks due to difficult evacuation conditions and confined operating environments.

An HL3 rating demonstrates that the product is suitable for use in virtually any railway application worldwide.

How Did Our Firesleeve Perform?

When tested in accordance with EN 45545-2:2020 requirements, our Firesleeve achieved compliance with:

R22 requirements
R23 requirements
HL1, HL2, and HL3 hazard level classifications

This confirms our Firesleeve is suitable for use across a wide range of rail and underground transport applications around the world.
