Delivering seamless tunnel safety upgrades with FireLaser in Lombardy

by Louise Seager

Strade e Autostrade magazine feature

We’re proud to share that Bandweaver’s fiber optic fire detection technology has been prominently featured in Strade e Autostrade, Italy’s leading infrastructure magazine, as part of a high-profile tunnel modernisation project commissioned by Anas in the Lombardy region.

Working in close collaboration with long-standing partners R.A.E.T. and S.C. Automazione (part of the VN Group), our FireLaser Distributed Temperature Sensing (DTS) systems were selected for a series of critical tunnel safety upgrades across multiple road tunnels in northern Italy.

“The real strength of the work carried out… was the possibility of integrating [the FireLaser control units] with existing PLCs, thus not requiring the customer to carry out further interventions and, in fact, optimising costs.”
– Strade e Autostrade, 2024

A scalable, non-disruptive upgrade path

Porlezza Tunnel side entrance

The project began with a technical validation phase three years ago, when R.A.E.T. supplied initial systems for evaluation. Following highly successful testing, the solution was adopted across a growing number of Anas-operated tunnels, including Lezzeno (SS36), Sant’Antonio (SS38), and Santo Stefano (SS42).

A key requirement from Anas was to enhance fire detection without requiring major civil works or tunnel closures. This was made possible by two unique strengths of Bandweaver’s FireLaser technology:

  • Remote system integration: FireLaser control units were installed in existing electrical cabins located outside the tunnels.
  • Utilisation of existing optical fiber infrastructure: Eliminating the need to install new cables or shut down tunnel sections.

Why FireLaser was selected

Bandweaver’s FireLaser DTS systems were chosen for their proven performance in harsh tunnel environments. Specific benefits highlighted include:

  • High-speed temperature acquisition
  • Large number of programmable detection zones
  • Immunity to tunnel airflow, dust, humidity, and exhaust fumes
  • Precise location detection across long distances

These capabilities ensure operators receive fast, accurate alerts to even the earliest signs of fire, allowing intervention before conditions escalate.

Custom software and rapid implementation

S.C. Automazione played a pivotal role in delivering seamless integration, providing customised software solutions to connect FireLaser systems with existing tunnel PLCs and infrastructure. Thanks to this approach, entire tunnel fire systems can now be restored or upgraded within a single day.

Improving safety without compromising operations

This project represents a forward-looking model for tunnel operators: delivering enhanced fire safety without large-scale retrofits or operational impact. By enabling modern sensing with minimal disruption, the FireLaser system is helping organisations like Anas achieve both resilience and operational efficiency.

We’re proud to support VN Group and Anas in this strategic effort to modernise Italy’s transport infrastructure and protect the lives of those who use it.

How Can Facilities Ensure Early Fire Detection in Hazardous Environments?

by Louise Seager

Industrial fires cause extensive damage across the globe each year, with the highest-risk fires found in environments where detection is most difficult. Those industries most at risk of insufficient detection are oil and gas, power, chemical processing, mining, and transport.

The consequences of delayed detection are serious, from risk to life, equipment damage, and environmental impact. This is why in many fire scenarios, the difference between minor damage and catastrophe less than 2 minutes.

Understanding detection challenges

Traditional fire detection systems operate at the mercy of their environments. They’re often compromised by environmental complexities such as dust, humidity, corrosive materials and smoke layering. Across widespread distributions such as cable tunnels and pipelines, traditional systems struggle to operate effectively over long distances in inaccessible zones. Variable airflow contributes further to these detection challenges by dispersing smoke unpredictably.

These are just some of the many ways conventional fire detection technologies fall short:

Smoke Detectors:

Smoke detectors predominantly rely either on beam detectors or air samples (aspiration detactors) reaching the detector, meaning in poorly ventilated areas or open spaces they may fail to detect smoke or are completely blocked in areas where there is dirt or particles in the air and cover the lenses or block the ducts. Additionally,, smoke detectors are more likely to raise false alarms in environments where they are bombarded by dust, fumes or aerosols. Over time this exposure can build up, blocking sensors and stopping detection entirely.

Flame Detectors:

These detectors require a line of sight to the flames to detect a fire. This has its downfalls, as flame detectors are rendered ineffective in the event of an early-stage fire where flames are not visible yet or have been concealed. Flame detectors have the same vulnerability as smoke detectors, where they can become blocked by dust and debris in the surrounding environment.

Thermal Cameras:

Thermal cameras are often more effective for detecting large heat sources, not subtle anomalies or spikes in temperature – meaning fires may not be detected until it’s too late. As with the previous detection methods, thermal cameras are also at risk of being blocked or damaged by environmental factors such as fog, controlled smoke clouds, or obstructions and they are also range limited and not suitable for larger areas .

The solution: Distributed Temperature Sensing (DTS)

DTS uses fiber optic cables as linear heat sensors, continuously monitoring temperature along the entire length of the cable. A laser pulse is sent along the fiber, using backscatter to analyse and determine the temperature at every point along the fiber. This enables real-time thermal monitoring over widespread distances.

Compared to traditional systems, Distributed Temperature Sensing has countless benefits such as continuous coverage with no blind spots, and immunity to environmental interference such as dust, exhaust fumes and humidity. DTS provides ultra early detection, identifying temperature spikes as soon as they appear, with accuracy within 1°C and 1 meter. To further enhance efficiency, DTS uses no moving parts meaning low maintenance and high reliability.

Inside the FireLaser system

FireLaser is a purpose-built solution for industrial and hazardous environments, consisting of fiber optic linear heat detection, precise location-based alerts, configurable temperature thresholds, and integration-ready functions for fire suppression, SCADA and ventilation.

The reason FireLaser is so effective is because of its high standards of monitoring even in harsh, confined, or hazardous environments. Long cable runs make the system cost-effective when covering large infrastructure as well as its resistance to environmental wear and electromagnetic interference. Explosive environments are sensitive to electronic interference making monitoring systems complex to implement, but FireLaser’s fiber is completely passive with no electronics in the field, making it the perfect solution.

Benefits for high-risk industries

Fiber optic linear heat detection is the ideal solution for numerous high-risk applications such as:

Oil and gas/chemical plants:

Fiber optic can detect heat build-up in cable trays, tank farms and processing areas, minimising the risk of explosions from equipment overheating – a threat that often goes undetected by traditional monitoring systems.

Power cables and infrastructure:

Monitoring power cable tunnels, busbars and substation infrastructure for overheating with fiber optic is an incredibly effective way of reducing blackouts or downtime caused by electrical fires.

Road and Rail Tunnels:

In tunnel fires is of the essence; fiber optic is able to spot fires before smoke reduces visibility or evacuation becomes unsafe or impossible. FireLasers integration with other systems also allows for ventilation or suppression systems to be triggered instantly.

Warehousing/logistics/factories:

FireLaser monitors racking, electrical cabinets or large storage areas with minimal infrastructure, providing vital fire detection to protect assets.

Data centres and battery storage facilities:

Critical systems are vulnerable to cable or battery overheating. fiber optic fire detection protects these systems by detecting the earliest signs of overheating through configured temperature thresholds.

FireLaser LHD

If a fire starts in a tunnel, how much time do you really have to react?

by Louise Seager

Imagine, you’re driving through a long tunnel when traffic starts to slow and suddenly, smoke fills the air. Visibility drops as headlights faintly glow through the haze; you instinctively check for an escape route but can’t see where to go. No warnings, no alarms. The tunnel becomes a trap, heat intensifying as toxic gases replace oxygen. Will emergency responders reach you in time?

Tunnel fires can reach 1,000°C in under 5 minutes – extreme temperatures such as these are hot enough to melt vehicles and infrastructure. One of the most dangerous environments for a fire to occur is in a tunnel, with limited exits, unpredictable smoke movement, and rapid heat build-up. This leads us to question: are fire detection systems reacting fast enough?

The science of fire spread in tunnels

Heat, smoke, and toxic fumes behave differently in a tunnel than in open-air environments. Often, tunnels are fitted with ventilation systems to reduce pollution; however, these systems can accidentally push smoke towards those evacuating. This means a superheated cloud of smoke and toxic gases travels faster than people can escape. Fire growth accelerates in this environment due to the confined space and poor ventilation, creating a wind tunnel effect that allows even small fires to grow rapidly. Temperatures also rise faster, increasing the risk of rapid flashover.

Traditional fire detection systems can take 2-5 minutes to trigger an alarm; this is often too late and allows fires to reach a critical size before suppression efforts begin. When comparing this to a timeline of fire escalation in a tunnel, the results are concerning:

– 1 Minute: A vehicle catches fire, building up heat without triggering an alarm.

– 3 Minutes: Thick clouds of smoke spread, making evacuation difficult.

– 5 Minutes: Flames engulf the tunnel; visibility drops to zero, and the fatalities are certain.

What if fire detection had happened at 30 seconds?

Emergency services would be alerted before the fire becomes uncontrollable for a more effective response, while tunnel operators can instantly trigger fire suppression or evacuation procedures. Overall, lives would be saved and damage to infrastructure minimised.

Why traditional fire detection fails in tunnels

Smoke Detectors:

  • Inconsistent, smoke moves unpredictably in tunnels due to ventilation and airflow complexities.
  • Exhaust fumes and humidity can cause false alarms or tamper with detection abilities.

Flame Detectors:

  • Due to requiring visible flames, fire detection occurs once a fire has escalated dangerously.
  • Blind spots within the tunnel can mean fires are missed.

Cameras:

  • Smoke can obscure vision before a camera can detect anything.
  • Thermal cameras only detect large heat sources, not early-stage temperature spikes.

False alarms are a significant downside of traditional detection systems; misinterpretation of dust, exhaust fumes, and environmental conditions leads to unnecessary closures and disruptions. Frequent false alarms can lead to alarm fatigue, which over time reduces the speed and efficiency of response times.

What happens when fire detection is too slow?

Failing to detect fires soon enough can have devastating effects. The Mont Blanc Tunnel Fire in 1999 is a harrowing example of this. One morning, a truck carrying flour and margarine caught fire inside the tunnel; this caused a rapid spread of both smoke and heat throughout. Due to fire detection systems failing to react in time, the fire was able to spread to devastating extremes while drivers were unaware of any dangers. As a result, people became trapped in their vehicles as flames engulfed the tunnel, causing 39 lives to be lost.

Comparatively, the Gleinalm Tunnel fire in 2018 was swiftly dealt with due to an innovative fire detection system. Within seconds the fire was detected, and tunnel fire suppression measures kicked in, allowing those in the tunnel to safely evacuate. This clearly shows the phenomenal impact of advanced fire detection systems in mitigating the risks associated with tunnel fires.

How FireLaser detects tunnel fires before they become disasters

Unlike traditional detectors, our cutting-edge fiber optic linear heat detection system FireLaser detects heat at its earliest stage, before flames or smoke even appear. This allows potential fires to be suppressed before they have a chance to spread. Due to the fiber optic sensing cable, organisations can rule out false alarms as the system is unaffected by airflow, vehicle emissions, fog, or dust.

To enhance fire response, FireLaser has real-time pinpoint accuracy to alert operators within seconds to the exact location of a temperature spike. Even in tunnels hundreds of meters long, the heat source can be located precisely, with no blind spots or gaps to ensure continuous monitoring. The versatility of our FireLaser system doesn’t just apply to its robustness and preciseness. FireLaser is scalable and adaptable to various tunnel types, such as road tunnels to prevent vehicle fires causing mass casualties, rail tunnels to ensure safe evacuation and train operator response, and utility tunnels to protect infrastructure from overheating cables or pipe failures.

Why tunnel operators & fire specialists choose Bandweaver’s FireLaser

Countless organisations globally trust in our fiber optic linear heat detection systems to guarantee safety in road, rail, and utility tunnels. FireLaser is proven to maintain its exceptional performance even in extreme tunnel conditions. Through successful implementation worldwide in high-risk tunnels, we know the system can withstand temperature extremes, humidity, and environmental contaminants.

We believe in making fire detection systems not only more effective in their performance but also in their usability as a tailored fire safety solution. FireLaser is highly adaptable, allowing easy integration into existing tunnel safety systems. Imagine how much quicker fire responses could be when FireLaser works alongside fire suppression, ventilation, and traffic management systems. This is also an incredibly cost-effective implementation, especially for larger tunnels, as there is no need for expensive infrastructure overhauls.

If you’ve worked with traditional fire detection systems, you’ll know the extensive maintenance required to keep them up and running. Through our FireLaser system, this is a thing of the past. With no moving parts or electronic sensors that fail over time, the system requires little to no maintenance over its long lifespan.

Every second counts

The difference between life and death in a tunnel fire is early detection. We’ve seen throughout the past decades traditional systems failing to react early enough, resulting in fatalities. It’s time for change; with the FireLaser system, tunnel operators have the best chance to detect and respond to fires quickly.

Our partners can offer their clients advanced fire safety solutions that allow for fast responses that save lives. Want to provide the best fire detection solutions for tunnels?

Enhancing safety: Advanced Linear Heat Detection System for Asian Battery Storage Facility

by WebbedFeet

A leading distributor of electrical components, including lithium-ion batteries, faces unique safety challenges. While lithium-ion batteries are generally safe, they can emit toxic fumes if they catch fire. In the event of thermal runaway, a rapid and uncontrollable reaction can cause the fire to spread quickly, leading to a chain reaction that is difficult to contain. Unlike conventional fires, extinguishing a lithium-ion battery fire may require up to five times more water, making it a particularly complex hazard to manage.

The client required a state-of-the-art fire detection system to ensure safety in their facility, which stores lithium-ion batteries in multi-story bays within high, three-dimensional warehouses. With 400 bays in total, these enclosed spaces pose challenges for conventional fire detection technologies like beam detectors, video flame detection, and aspirating systems. Initially, the client considered installing low-cost smoke detectors in each bay, but they also sought a solution capable of detecting heat rise before thermal runaway occurs and before smoke is emitted, ensuring early intervention and minimising the risk of a fast-spreading fire.

Predicting the future of the fire industry: key technologies to drive innovation

by Louise Seager

We live in an age of Artificial Intelligence and technological excellence that is consistently evolving to solve the many challenges businesses face. This impact can also be seen in the fire protection and prevention industry as new ways to detect and prevent fires emerge. Businesses within the fire industry have the opportunity to enhance and optimise their approach to fire protection in order to provide their clients with stronger, more effective solutions.

Why are preventative measures vital?

Each year in the UK, around 22,000 workplace fires occur with the potential to kill or seriously injure employees and customers and damage or destroy buildings, equipment, and stock. The financial repercussions are extensive, meaning 60% of private businesses never fully recover after a fire. On average, fire damage costs businesses £65,000, often a far higher cost than the price of implementing effective fire protection.

For this reason, we are dedicated to providing effective, reliable fire detection solutions to safeguard the future of our clients’ businesses. Our Linear Heat Detection systems allow monitoring over a wide distance and are specially tailored to suit hazardous environments. Fiber Optic distributed temperature sensing is one of the most effective key technologies available, especially when combined with our smart software and services to provide operators with the right information at the right time. This enables swift decision-making to minimise damage, avoid catastrophic failure, and reduce the financial, environmental, and reputational risk.

While this technology is at the forefront of fire protection due to its unique features and robust, reliable temperature sensing abilities, there’s always space to develop and evolve. Below are some of the key technologies expected to revolutionise the fire industry:

Artificial Intelligence

Arguably one of the most controversial tech developments, the evolution of AI is expected to have an exponential impact on the fire industry. With intelligent machine learning and uniquely tailored algorithms, AI can transform our approach to fire detection with abilities that far outweigh those of traditional systems.

Whereas current systems rely on sensors, beams, or the presence of a flame, AI can act as a constant surveyor from a remote location for early detection. An incredible case of this in practice is the ALERTWILdfire Network in the United States of America. Their system uses AI to monitor and analyse live video streams from hundreds of mountaintop cameras to detect smoke or potential fires. Through machine learning, the algorithm can detect potential fires far earlier than traditional systems to alert first responders and fire departments. Quicker response times are vital; containing the fire earlier eliminates the risk of widespread damage to the wildlife that would have a significant environmental impact.

AI’s ability to handle and analyse data to discern patterns can be utilised by the fire industry to enhance the efficiency of resource allocation. By partnering with technology companies, the London Fire Brigade has worked to develop an AI-powered software designed to revolutionise resource allocation. The software analyses historical fire incident data and other necessary information to predict high-risk areas for fires. Using this information, the London Fire Brigade can allocate resources efficiently to areas they’re needed most, as well as target prevention efforts in specific districts.

Virtual Reality

The use of virtual reality for training and simulation is not unheard of; however, this is now being utilised to provide accessible training for the masses. ‘Project iEvac’ was developed by the NFPA as a VR training program for teaching safe evacuation in the event of a fire. Using virtual reality, the training module can simulate various fire scenarios under different building environments, giving users the chance to experience the difficulties and complexities of evacuating a building due to a fire. The VR headset takes users through interactive exercises, testing their evacuation skills, decision-making abilities, and situational awareness.

The availability and costs of training equipment and tools can be a significant obstacle to equipment familiarisation. With VR, firefighters can be trained on the proper use and operation of various tools and equipment through simulations. The US Navy has begun using a VR training module that includes various scenarios such as shipboard fires, engine room emergencies, and aircraft carrier flight deck incidents. These immersive training exercises use VR headsets to simulate real-world situations and practice the use of firefighting tools such as fire hoses, nozzles, breathing apparatus, and thermal imaging cameras.

The ability to recreate an incident using VR makes it a brilliant solution for incident command training for fire officers and incident commanders. The FDNY uses VR for incident command training with modules using simulations of large-scale emergencies, multi-alarm fires, hazardous material incidents, and mass casualty incidents. These engage incident commanders in immersive training exercises to practice managing complex incidents, coordinating response efforts, allocating resources, and communicating with personnel on the ground.

Robots

Emerging technology, especially robotics, is revolutionising the fire industry by offering solutions that allow access to hazardous areas without putting personnel at risk. A prime example of this is the Tokyo Fire Department in Japan, which has integrated robots into its firefighting and emergency response operations.

One standout innovation is the “dragon drone,” a robotic system equipped with thermal imaging cameras and advanced sensors. This drone can navigate smoke-filled environments, providing real-time data on fire conditions, such as identifying hotspots and locating potential victims. With the ability to fly into hard-to-reach or dangerous areas, the dragon drone enhances situational awareness and helps firefighters make more informed, strategic decisions.

By utilising robotics like the dragon drone, firefighting teams can reduce human risk, speed up response times, and improve overall efficiency in managing fire incidents. As these technologies continue to evolve, the fire industry will see even greater benefits in safety and operational effectiveness.

Advanced Sensors

Emerging technology, such as intelligent sensors, is enabling organisations to make more informed and efficient decisions when it comes to fire safety. A great example is the use of fiber optic Linear heat Detection (LHD) systems, like our FireLaser solution, which are transforming fire suppression strategies.

In Italy, Autostrade per l’Italia has implemented Bandweaver’s FireLaser system in the Santa Lucia Tunnel, a structure over 10 km in length. With the FireLaser LHD controller, they can pinpoint the exact location of a fire within 1 meter. This precision allows the fire suppression system to concentrate its efforts on a specific zone, targeting an area less than 10 meters in size.

By focussing suppression efforts so accurately, Autostrade achieves early fire detection, minimises resource use, and significantly reduces both fire risks and water damage. As this technology becomes more widely adopted, the fire industry stands to benefit from greater safety, cost-efficiency, and enhanced protection for critical infrastructure.

Prepare for the future with Bandweaver

Our mission is to provide businesses with the vital technology needed to protect themselves from the catastrophic damage caused by fires. To achieve this, we are constantly working to provide the most innovative, effective systems as possible.
