Water might seem like the simplest part of firefighting – just point and spray, right? Well, as you can imagine, the reality is a bit more complex. In this conversation with veteran firefighter and CFBT instructor Szymon Kokot, we pull back the curtain on firefighting's most critical resource to reveal the intricate science and logistics behind effective fire suppression.
Did you know a standard fire truck carries just 10 minutes' worth of water for a typical residential fire? Or that a water-filled fire hose can weigh up to 45 kilograms per 20-meter section? These physical realities shape every aspect of firefighting operations and explain why building water supply systems are absolutely vital for effective emergency response.
Szymon walks us through essential concepts that every fire engineer should understand – from critical flow rates (2 liters per minute per square meter of fire area) to tactical flow rates (4 liters per minute per square meter) that provide both effectiveness and safety margin. We explore how water's cooling capacity works primarily during evaporation, why cooling burning materials is more important than extinguishing visible flames, and how different water application techniques serve different tactical purposes.
The conversation demystifies hydrants versus standpipes, dry versus wet systems, and the specialised requirements for different building types – especially the unique challenges of high-rise structures where external water supply is virtually impossible. We also confront the all-too-common reliability issues that plague these systems, from maintenance problems to vandalism.
Whether you're a fire engineer looking to design more effective systems, a firefighter interested in the science behind your craft, or simply curious about this intersection of physics, engineering and emergency operations, this episode delivers valuable insights into how water – our oldest firefighting tool – continues to shape modern fire safety design and operations.
