Firefighters can make faster progress in a highly smoke-filled tunnel thanks to the search stick than without it. It goes even faster as soon as they are sufficiently trained and familiar with the search stick. It is one of the many interesting findings of a study carried out by Karel Lambert of the Brussels Fire Service with the support of Ghent University. The tests also provided new insights into the air consumption of BA Teams, which we briefly present in this magazine article. The…

Course participants repeatedly ask whether structural cooling is necessary for firefighting operations in road and railway tunnels. Our Didactics and Development Team has therefore reexamined this question and has come to the following conclusion: Structural cooling is an option and not a must. When in doubt, however, cooling should always be used to protect the firefighters. In this article, we explain the reasons for structural cooling.

A fire in a passenger aircraft is rare but dangerous and can endanger many lives. Very few firefighters have ever experienced such an operation. At the same time, training opportunities are limited: Even access to an aircraft is only possible in exceptional cases, for example, when an aircraft is being serviced overnight. For this reason, more than 300 firefighters at Berlin-Brandenburg Airport (BER) have now trained virtually to extinguish a fire in a passenger aircraft. An experience report.

On 13 June 2024, a violent explosion occurred in an underground car park in Nussbaumen in the Swiss canton of Aargau, causing extremely unusual damage. As a result, 12 neighbouring buildings were damaged, and 60 flats became uninhabitable due to the spread of fire and smoke. Two people were killed and 12 were injured. Deputy incident commander Philipp Puliafito gives an insight into how this unusual incident was resolved and how the fire services were deployed for days on end.

Two questions are repeatedly asked in our courses for firefighting operations in road tunnels: When searching for people in a smoke-filled tunnel, do you also have to search under the vehicles? And: Do you also have to search a car's boot? One thing is clear: Only those areas into which people could easily flee or fall should be searched.

For Switzerland, a rule on safety for operations on railway infrastructure has been reworded. The most significant change: Previously, it was stated that emergency personnel were only allowed to work in the danger zone when «railway traffic has been discontinued». From now on, the wording is «track closed». This article presents the new safety rule for Switzerland, explains the reasons for the change and advises on practical implementation.

Incident commander Andreas Gerber reflected on his experiences from an underground car park fire in Aesch in the canton of Basel-Landschaft (CH). In this article, we summarise his key findings.

Since the International Fire Academy was founded, he has been part of the team: instructor and training consultant Markus Vogt. He retired on 30 June 2024 - and will remain associated with us for special projects. In this article, Markus Vogt gives a very personal review of fifteen and a half years at the International Fire Academy.

We are occasionally asked why we use cold fire projections in our railway training tunnel in Balsthal in addition to gas-operated fire mockups. This article shows how we use flame projections to protect people, the environment and equipment and why this has also proven to be advantageous from a didactic point of view.

The latest investigations by the Research Centre for Fire Protection Technology at the Karlsruhe Institute of Technology show that: If hydrogen is released from a hydrogen-powered vehicle in an underground car park, it quickly dissipates from the structure under favourable structural conditions. Positive pressure ventilation can hardly accelerate this process in the special situation investigated. However, it would probably not pose a hazard under these conditions, as positive pressure…

A recurring question from our course participants is: «What should we do if we come across locked vehicles in a smoke-filled tunnel during a search?» Our Didactics and Development Team has discussed the question and recommends: «Make yourself noticeable. If there is no response from the vehicle: Do not open it and search the next vehicle.»

«Know your tunnel» is one of the most important teachings of the International Fire Academy. In this article, we provide suggestions on how firefighters can organise and design inspections of railway and road tunnels and what needs to be considered.

Firefighting operations in tunnels are personnel-intensive, and the procedure must be trained. Many fire services have part of their personnel trained at our facility. However, that is not enough. The routines for these deployments must be practised with the entire team. It is why many participants asked for tips and examples for training at their location. This resulted in a new offer for fire services: the «Training Methodology» advanced modules.

There are no official statistics on fire incidents in underground transport systems. For this reason, the International Fire Academy has been analysing media reports on fire incidents in tunnels since the beginning of 2012. According to the report, there are at least three fires a month in railway or road tunnels in Switzerland, Austria and Germany alone.

Clemens Pessel is the new central contact for fire services outside Switzerland at the International Fire Academy. Since summer 2023, he has been working closely with his predecessor, Markus Vogt, to prepare to take over the role of training consultant for German and English-speaking fire services. Since 1 January 2024, he now bears the main responsibility. In the interview, both explain how the preparations for this handover occurred.

It was the first time the Nagold volunteer fire service was alerted to a major fire in an underground car park beneath an apartment building at 3:01 a.m. on 8 July 2023. The residents of the house with 16 residential units had already left the building. At the end of the operation, fire chief Thomas Reiff was glad that no one was injured, including firefighters, which would not be unusual in such an operation. Since then, the issue of underground car park operations has received increased…

At 0:55 a.m. on 21 June 2023, the alarm was raised at the Swiss Federal Institute of Technology (ETH) Zurich: Hydrogen leakage in the compressor room on the 2nd basement floor. The initial measures were immediately apparent for Daniel Münzenmayer, a member of the Zurich professional fire service for 37 years. He summarises how he experienced the deployment in his report.

Underground car park fires are particularly dangerous - especially for the firefighters. That is why the International Fire Academy has developed a special intensive course. It has now been offered as a «mixed course» for the first time in which individual members of different fire services could participate. The aim is to allow as many fire services as possible to deal with the particular challenges of fires in underground car parks. The 2024 dates have already been advertised.

The International Fire Academy has put its new Tactics Centre into operation. Larger rooms and modern tabletop exercise technology offer significantly better training conditions for tabletop exercises as an essential element of tactical training. The new Tactics Centre is also increasingly being used for valuable tactics workshops.

Shortly after being alerted to the fire of an ICE train in the underground Cologne/Bonn airport station on 10 November 2022, the Cologne fire service in charge received an initial all-clear: «ICE already evacuated». Nevertheless, four people suffered smoke inhalation injuries from the fire - three of them outside the station area. Daniel Richmann from the Cologne Fire Service and Luca Battista from the supporting Airport Fire Service at Cologne/Bonn Airport describe the course of the operation.

In the Violet Crown Cinema, Austin (USA), Angelika Stenzel-Twinbear first discovered a lift designated as an escape route in case of fire. Since then, she has been intensively involved with this topic because, as a specialist engineer for fire protection and barrier-free planning and construction, she wants to contribute to getting as many people as possible out of the building as quickly as possible in the event of a fire. In our article, she explains how this can be done in practice. She also…

Those who want to get to know many different tunnels in the smallest of areas can do so on the Portuguese island of Madeira. In 2020, there were 127 road tunnels on the island. More will be added through the expansion of the motorways. In order to prepare firefighters for operations in road tunnels, all instructors of the São João da Madeira Fire Training Centre participated in the first intensive road tunnel course on behalf of the Escola National de Bombeiros (ENB) in Sintra, Portugal, in…

The evaluation of tunnel incidents has shown: Tunnel users do not necessarily follow the designated escape routes. They try to use all means to get out of a tunnel: Turning their vehicle around, getting into other vehicles, and trying to escape on foot through the tunnel tube to the portal. All this corresponds to the natural escape behaviour of humans, including remaining in the vehicle. It is because people perceive several different risks, which they weigh against each other to make their…

Before fire services can use the potential of robots on a larger scale, Robert Grafe, Managing Director of the German Rescue Robotics Centre (Deutschen Rettungsrobotik-Zentrums; DRZ) in Dortmund, sees a considerable need for research and development. It does not primarily refer to the utilised technologies. Rather, it is about practical experience gained through field research and from incident operations.

For drills and trials in newly constructed tunnels, fire services in Hesse wanted a smoke generator that would allow them to simulate the behaviour of fire smoke during a major incident in a tunnel as realistically as possible. But such a device did not exist until now. This lack was shown in 2019 by a market analysis conducted by district fire inspector Christian Sasse (Werra-Meissner district). After this analysis, development work began on the FT-SDAN 500 tunnel fire simulator, which Volker…

Two topics dominated the feedback from the firefighters from Belgium who completed the one-and-a-half-day intensive underground car park course at our training car park: tactical ventilation and hose management. Many things were new and good for the participants, which they are now evaluating for further training at home.

Modern road tunnels support self-rescue with their safety installations. But people do not behave in an ideal way - especially not in dangerous situations. Even if a tunnel facility meets all safety standards, every person in the tunnel can be at risk during a fire - not just people for whom escape would be troublesome. Unfavourable behaviour is often simply human. It is something that firefighters should also expect. In our three-part series, we first look at the behaviour of tunnel users in…

In order to decide what to do in the event of a fire incident in the tunnel, tunnel users need information. If they are standing in a traffic jam at some distance from the incident, they are usually unable to assess the situation themselves. They are dependent on information. Therefore, tunnel users often look to others for guidance. It can have both positive and negative effects.

The appreciative feedback of the participants to the 9th Fire Chief Forum in Sursee (CH) shows: The forum as a non-public space for (self-)critical, honest exchange about incident operations, drills and developments is an important building block in preparation for incidents in railway and road tunnels. In the following article, we present interesting findings from the most recent Fire Chief Forum held in March 2023 and highlight the broad range of topics covered at this event.

«Why do you only use white and not black training smoke?» This is a question asked by many course participants who prepare for deployment in our training tunnels. The simple answer is: White training smoke, when used correctly, is not harmful to health or the environment and is perfectly sufficient for our training goals. In this article, we explain the benefits of white training smoke and provide guidance on using smoke fluids for operational drills. 

The Seattle Fire Department is currently creating its own tunnel operations procedure to address a variety of road, rail and metro tunnels and the challenges they present to responders. Operational planners had already informed themselves at the International Fire Academy in 2016. At the end of 2022, 14 North American fire service colleagues came to Balsthal to gain practical experience with our operational procedures and get ideas for their further development work. In the process, the Swiss…

A fire in a railway or road tunnel can endanger many people within a short time. How many firefighters are needed for such an incident depends on many factors. Therefore, there is no across-the-board answer to the question: How much training does a fire service need for tunnel operations? Instead, a development process is necessary. Our guide shows the most important steps on the «pathway to your training», which fire services can also use for their meetings with the financing body.

In cooperation with the Baden-Württemberg State Fire Service School, the International Fire Academy has integrated online elements into the tunnel training for the first time in order to increase the practical part of the attendance days in Switzerland. The basis for the changes was a survey of former participants. The wish list included more time for practical training on the facilities and more substantial support for conducting training with the fire services at home. We present the new…

The International Fire Academy instructs: If a rail vehicle approaches the scene of the incident, the driver must be given a hand signal. Course participants frequently wonder whether this is really necessary. That is why we asked a train driver at the Swiss Federal Railways (SBB) directly and got the answer: «Yes, it is extremely important. It helps us very much!». Find out why.

Firefighters can protect themselves against smoke, heat and fire spurts, but not against the blast waves from explosions of hydrogen vehicles in tunnels. Therefore, it is vital to keep a safe distance. However, how can people be saved and fires be fought effectively? There is still no satisfactory answer to this question - although more and more hydrogen-powered vehicles are being registered. That is why the fire services need to work on suitable solutions immediately. This is the most important…

The underground car park leaflet is more than just a handout for our intensive course. It takes the concept of our teaching posters and translates it into a compact format for on-site training. The texts are reduced to a few words and provide the crucial keywords for the illustrations in German, English, French and Italian. Photographs from actual operations, our training operations and installations in underground car parks relevant to operations provide the necessary illustrative material in…

Postponed twice - then the Interschutz finally got underway again. We were able to build on our attendance in 2015 and reached our target audience in Hannover again this year: Fire service supervisors, builders of tunnel facilities and other contacts for preparing for operations in underground transport systems.

The 8th Fire Chief Forum placed emphasis on incident reports and covered a broad spectrum: two lorry fires in road tunnels, an underground metro fire, and two train fires, one on open track and the other one within a settlement. Social media and the usage of large mobile fans in deployments were two other topics from the practical side of firefighting operations. Looking beyond the world of fire services, the focus was on the behaviour of those caught up in an evacuation as well as special…

At the beginning of 2019, the Matterhorn Gotthard Railway put two new fire and rescue trains into operation, each consisting of a combination of road-rail vehicles and rail-only vehicles. We visited Christian Imsand, the head of the Furka Base Tunnel Rescue Service, and Roland Guntern, the operations manager of the operational fire service, in Oberwald to learn more from them about this rescue apparatus, which is unique in some respects.

During tactics training at the International Fire Academy, questions are repeatedly asked about command structure and tactical practice at the fire service's location. Therefore, in this article, we have once again compiled important information on command structures and also address the special challenge of operational communication, which, according to our experience, should be practised very intensively. 

Because the detail lessons of reconnaissance, search & rescue and firefighting cannot be carried out in parallel in the railway training tunnel, a training concept for a maximum of 16 participants per standard railway course was initially developed. Thus, all lessons could be carried out in two days in the sense of experiential learning. However, one problem remained: Especially for the training drills, groups of up to 24 participants had proven themselves in all other courses of the…

In training operations, it is regularly noticed that the danger of reversing airflow direction and thereby reversing smoke propagation during fire operations in tunnels is generally underestimated. That is why we address this topic, which is extremely important for the safety of the emergency personnel, in this article and show how the risks of a sudden reversal of airflow can be reduced.

For most operations in road tunnels, the fire services can drive their vehicles directly to the incident scene. On the other hand, in most railway tunnels, this is only possible with special vehicles, for example, fire and rescue trains or road-rail vehicles that can travel on roads and on rails. This article provides an overview of the most important vehicle types and their tactical advantages and disadvantages.

From the perspective of experiential learning, learning cannot be limited to the acquisition of knowledge. The focus is instead on experiencing relevant situations and challenges. At the same time, the importance of specialised knowledge should not be underestimated when firefighters want to tackle tunnel fires jointly. The necessary basic knowledge for tunnel operations as well as helpful background information are presented compactly in words and pictures in the specialist books «Firefighting…

After the major fires in road tunnels in 1999, the prevailing opinion was that fire services could do little about tunnel fires. Today, most fire services consider themselves well equipped for this task. Urs Kummer, CEO of the International Fire Academy, and Christian Brauner, head of the Didactics and Development Team, trace the development since 2001.

The preparatory and practical courses «Fire Fighting in Road and Rail Tunnels» at the Thuringian State Fire and Civil Protection School (TLFKS) place high demands on the participants. In order to boost motivation and attention to the extensive learning content, the training team relies on adventure-based educational elements.

Even though underground car parks are underground transport systems, the operating conditions differ significantly from those of a fire in a tunnel. Therefore, full-time instructors, together with the Didactics and Development Team of the International Fire Academy, developed tactical principles and guidance on practical procedures for operations in underground car parks. They are taught in the underground car park intensive course.

After the major tunnel fires in the Mont Blanc and Tauern road tunnels in 1999 and the Gotthard Road Tunnel on 24 October 2001, the Federal Roads Office (FEDRO) reviewed all national road tunnels with a length of more than 300 metres for possible optimisation of tunnel safety. We spoke to Christian Gammeter, Head of Tunnel and Geotechnical Engineering in the Infrastructure Standards and Safety Division, about the current status of safety measures.

24 October marks the 20th anniversary of the major fire in the Gotthard Road Tunnel. After the collision of two articulated lorries, an electrical short circuit caused a fire to break out in one of the tractor units, which quickly spread to five other lorries. Eleven people lost their lives. We wanted to know how the Gotthard portal fire service has changed since this incident and visited the deputy commander of the Schadenwehr Gotthard, Beat Walther, at the Göschenen depot.

More and more hydrogen-powered vehicles are on the roads and thus also in tunnels and underground car parks. That is why the International Fire Academy is involved in the «HyResponder» project. With fire services and fire service schools from several European countries, a special training course is to be developed for vehicles and systems with fuel cell technology. At the halfway point of the three-year project, we provide an interim report in the following.

When rescuing people from smoke hazards, fire services use fire escape hoods as standard. Respiratory devices with filters protect the persons to be rescued from toxic fire gases by filtering them out. However, if the air breathed in through the filter contains too little oxygen, there is a risk of severe health damage after only a short time. This article explains why fire escape hoods with compressed air should be used for long rescue routes, which can supply the persons to be rescued with…

In 2002 we developed our first didactic concept. The focus was on how the tunnel training facilities must be designed to provide both realistic and sufficiently safe training conditions. The now updated didactic concept of the International Fire Academy focuses on the learning model and teaching methods that underlie our training operations: We offer worlds of learning and experience - the course participants themselves do the learning.

The basis for the development of the search stick was the so-called long canes for visually impaired people. The search sticks are a further development of this product and have been optimised for fire service operations. The International Fire Academy is now launching the third version of its search stick. The new model is expected to be available for delivery from August 2021. The article explains the innovations and gives important advice for use.

Fires in railway tunnels are rare. However, many hundreds of people may try to save themselves and rush to the emergency exits when such an incident occurs. In order to support them and to receive critical information from the people escaping about the situation in the tunnel, all emergency exits should be manned as quickly as possible. To successfully man all exits, a jointly prepared operational plan by railway companies and rescue organisations is required.

During the International Fire Academy training operations, it became clear that the members of a search & rescue team can be coordinated in different ways. However, which variant is the best? The International Fire Academy's Didactics and Development Team has analysed the complex issues and now recommends that the safest course of action be taken as default: The entire search & rescue team, including the team leader, moves and works spatially as close together as possible.

In 2014, the Swiss railway infrastructure carriers commissioned the International Fire Academy in Balsthal (CH) to develop a firefighting procedure for fire incidents in railway tunnels. At first glance, a simple task. This is because the International Fire Academy had already laid the essential groundwork with its Firefighting Procedure for Road Tunnels. However, the first realisation in what was ultimately a four-year development process was: The operating conditions for fire services in…

One of the greatest challenges during operations in underground transport systems (UTS) is the transport of persons who are unable to escape over long distances. Without any transport aids, the emergency personnel can quickly reach the limits of their physical capabilities. Which equipment is best suited depends on the specific task as well as the type and design of the respective UTS. The following article provides guidance on how the question of the most suitable transport aids can be…

For each tunnel, both location-specific and facility-specific preparation for operations is required, which must be developed together with the carrier and, if necessary, the builder of the tunnel. The earlier this is started, the greater the chance of creating good working conditions for the fire services, improving safety and avoiding unnecessary costs.

Within a very short time, the Fire Service Reutlingen had to prepare itself to provide rescue services for the construction phase of Scheibengipfel Tunnel in Reutlingen. The International Fire Academy supported the fire service by giving its officers the opportunity to quickly familiarise themselves with the special conditions of underground transport systems and practically test their tactics and techniques under operational conditions.

No PowerPoint slides, no long lecture. Instead, practical exercises in feedback communication right from the start. Marianne Wernli surprised even the experienced instructors at the International Fire Academy with her 90-minute training session. It started with the description of a traffic accident.

The harmonisation and quality assurance of fire service training is one of the central tasks of the Fire Service Coordination Switzerland (FSCS). For this purpose, it relies, among other things, on the voluntary certification of training offers with the FSCS Quality Label. By the beginning of 2021, 27 courses throughout Switzerland had received this quality certificate. Among the applicants, the International Fire Academy is at the forefront with four courses.

On 28 November 2020, the Zederhaus fire service (A) was alerted to a lorry fire in the Tauern road tunnel. On-site, dangerous goods boards and a huge bang brought back bad memories of the major fire in May 1999. At that time, twelve people were killed. This time, however, the operation was far less dramatic than feared after the first shock. We spoke to the chief of the Zederhaus fire service and incident commander Harald Pfeifenberger.

In the initial phase of fire operations in underground transport system (UTS), there is often a shortage of personnel. That is why many participants ask us whether reconnaissance teams are really needed. Our answer: It depends on the situation. Reconnaissance teams are needed above all when vital information has to be obtained as quickly as possible.

The «heart» of pumped hydroelectric energy storage is located deep inside a mountain: In a cavern, pumps and turbines are installed in huge halls. The access tunnels are usually several hundred meters long. Individual company fire services have recognized the similarities between their facilities and other underground transport systems such as tunnels. They use the training infrastructure of the International Fire Academy in Lungern and their teachings for their preparation.

The leaflets of the International Fire Academy summarize essential contents of the firefighting operation procedure for firefighting operations in railway and road tunnels. They are now available for the first time for railway tunnels and in the second edition for road tunnels in the «Knowledge» section as a download and are also available as printed copies. Both the pdf files and the leaflets can be used for training on-site.

On 5 and 6 October 2020, the International Fire Academy organised a workshop on «First responding to incidents with hydrogen-powered vehicles». It was possible to formulate relevant issues for scientific research on the specific problems of incident operations. The International Fire Academy conducted the workshop online and connected it for the first time with another first: The IFA took the chance to use the proven tabletop exercise technique in a video conference.

On 2 June 2020, a car burned down in the Bürgerwald Tunnel near Waldshut-Tiengen (D). Eleven people suffered smoke inhalation injuries. We spoke with fire chief Peter Wolf about the most important findings from this firefighting operation.

The International Fire Academy recommends to always proceed towards the fire in tunnels when reconnoitring or performing search & rescue. This article explains in detail why this can significantly reduce the risks of firefighters.

The training kit is packed. Shortly before departure Markus Vogt included the latest tunnel incidents in his presentation. Next to the laptop are thick rolls of paper and printouts for case studies and communication exercises. Information and practical training sequences will alternate for the approximately 50 participants during the one-day on-site training.

The instructors carefully observe their students in the training tunnel. They assess their level of education and give precise, short feedback after the joint reflection of each course unit. It is precisely this exchange that brings momentum to the training: The instructors respond individually to their students and at the same time, ensure a uniform training. This requires a clear training concept and regular readjustment.

How much personnel is required for firefighting operations in a road or rail tunnel? This question cannot be answered in general. Therefore, in this article, we provide some information for the facility- and site-specific personnel requirements planning.

If fuel cell technology becomes more widespread, hydrogen-powered vehicles will also be operated in tunnels and underground car parks in the future - and could catch fire there. This is why the International Fire Academy is involved in the European research project «HyTunnel-CS», which aims to develop hydrogen vehicles as safe as possible.

There are no official statistics on fires in underground transport systems. In order to get an idea of the frequency of fires, the International Fire Academy records all fire incidents in road and rail tunnels, which are reported by German-language media. This page provides an overview of the statistical evaluations as of 31. October 2019.

In 2014, the International Fire Academy launched its textbook series "Interventions in Underground Transport Systems" with the title “Firefighting Operations in Road Tunnels". The second volume is currently being written. “Firefighting Operations in Railway Tunnels" is due in March 2020.

Preparing for the most varied of scenarios as realistically as possible is a central concern of the Regio Basel Industrial Fire Service (RBIFS). «We are therefore looking for places like the Intercantonal Fire Service Training Centre in Balsthal,» explains Oliver Hofer, Fire Chief of the RBIFS Schweizerhalle. There, the RBIFS books the training infrastructure to conduct its own courses.

The Tactics Centre of the International Fire Academy is used for the education and training of incident commanders. With the specially developed projection technology, all conceivable scenarios can be represented and played through by the course participants. A central topic of practice is always communication via radio.

The didactics and development team, DDT for short, is responsible for the development of the International Fire Academy's operational procedures and defines the didactic principles. It is made up of experienced firefighters and experts in the construction and operation of traffic tunnels.

The scheduling and shorter journey for the participants were the reason for Markus Hostettler 2019 to move the respiratory protection module 3 (operation) of the Swiss Fire Service Association (SFSA) from Andelfingen to Balsthal. Not an easy task for the course manager, because differences between the training facilities influence the course of the training.

Planning is the most important tool so that everything works as reliably as possible on our training facilities, in the classrooms and the entire infrastructure. Eight employees in the maintenance department take care of the many big and small tasks. Operations manager Markus Burger explains what happens backstage in Balsthal and Lungern.
