Differences Between Road Tunnel Fires and Building Fires Fires in road tunnels differ significantly from those typically encountered in buildings. Road tunnel fires occur in a highly confined space with limited ventilation, which causes heat and smoke to accumulate rapidly rather than dissipate. Vehicle fires, especially those involving heavy goods Read more
Electric Vehicle Fires in Tunnels: passive fire protection perspective The rise of electric vehicles (EVs) has prompted research and changes across many aspects of transportation infrastructure, including tunnel safety. Fire protection in tunnels is a crucial area where new technologies, like EVs, require reassessment and adjustment. As EVs, including trucks Read more
The hydrocarbon fire curve (HC curve, also called the hydrocarbon time-temperature curve or ASTM E1529/ UL 1709 curve in some contexts) is a standard nominal time-temperature exposure used in fire-resistance testing of structures, particularly for hydrocarbon pool fires (e.g., petrol, diesel, or HGV loads in tunnels). It features a very Read more
Fire boards for tunnels are an important asset that protects integrity of the structure. Safety is paramount, and passive fire protection in tunnels is a critical consideration. Selecting the right fire protection board for your tunnel project is essential to ensure the safety of users and infrastructure in the event Read more
ISO Fire Curve The ISO 834 curve, often referred to as the standard fire temperature curve, is a baseline thermal stress model used extensively in the construction industry. It’s one of the many time-temperature fire curves which are also used in designing fire protection in tunnels. It represents the minimum Read more
Why Magnesium Oxide Boards (MgO boards) Are Not Suitable for Tunnels Magnesium oxide boards, commonly referred to as MgO boards, have gained popularity in the construction industry for their fire-resistant properties, lightweight design, and ease of installation. These factory-made sheathing products, often reinforced with glass fiber mesh, are typically composed Read more
Fire safety in tunnels is a critical concern for modern infrastructure, where the confined spaces can turn even minor incidents into catastrophic events. Tunnel fires pose significant risks, including loss of human life, extensive structural damage, potential collapse, and widespread economic disruption such as increased traffic congestion, reduced tourism, and Read more
RWS Fire Curve: A Key Tool for Tunnel Safety and Tunnel Fire Protection Fire safety in tunnels is a critical aspect of modern infrastructure design, especially when it comes to preparing for extreme fire events. One of the most important tools used to model and mitigate these risks is the Read more
Introduction to Passive Fire Protection in tunnels Passive fire protection In the realm of fire engineering is a concept which stands as a cornerstone in ensuring the safety and integrity of structures, particularly in environments as challenging as tunnels. Passive fire protection encompasses a range of measures designed to contain Read more
Concrete Spalling in Tunnel Fires: Causes, Effects, and Prevention Concrete spalling is a critical concern in tunnel engineering, especially when it comes to fire protection. As tunnels become increasingly vital for transportation and infrastructure, ensuring their resistance against fire-induced damage is paramount. This blog post delves into the phenomenon of Read more
