Particleboard How To Protect Your Home From Burning Debris From Forest Fires By John D. Austin Last updated Oct 3, 2021 0 Share The story continues What surprised me at the time was how little time people spend preparing embers, although they go to great lengths to protect their homes by watering the land. What I realized was that my parents and their neighbors, like many of us, were planning to protect homes like preventing a wall of flames from reaching their homes. They did not understand that in some cases the greatest threat could be carried by the wind. Three stages for fires started by brandons Fire scientists speak of point fires as occurring in three stages: how brandons are generated, how they are carried by the wind, and how they land and ignite fuel. Fire scientists, including those in my research group, are actively studying each of these steps to be able to better predict and ultimately reduce the risk to firebrand communities. Brandons are generated by the combustion of vegetation or structures. The sizes of the brandons can vary, but can be as small as several square millimeters. Embers can come from pieces of bark, branches, cones or burning needles if the source is a forest fire. For urban fires, brandons can come from the roof, siding, particle board or other flammable materials. Over the past two decades, efforts to study brandon generation have often focused on quantifying the number of brandons that land in particular places when trees or other vegetation burn. More recently, researchers are trying to estimate the total number of brandons that are released when objects burn. To estimate the number of brandons a fire generates, we placed squares of fire-resistant fabric around burning trees and shrubs, such as Douglas-fir and sagebrush, and collected the brandons that landed. . By determining the total number of brandons per unit mass of the burning tree or shrub, we can incorporate data into computer models to estimate the total number of brandons released in a fire and where they spread. Ultimately, we hope that these models can be used to better understand the risks associated with forest or urban fires. Much research effort has focused on developing models that capture the physics of how embers are transported or where embers are most likely to land. The nature of the burning of embers during transport is an important factor. Brandons can be flaming or smoldering. Both can cause new fires. The third step is the ignition of fuels – such as fences, mulch and needles – after the brandons have landed. Researchers are studying the heating potential or temperature of brandons. Understanding this information is essential to implementing building codes and standards and best practices to better protect homes. We are also working to better understand what characteristics of fuels determine whether they ignite. How can homeowners reduce the risk? So what can homeowners do to protect themselves from the risk of one-off fires? First, start by changing your mindset regarding preparedness, not if, but when a fire occurs nearby. I admit that as a homeowner living near a forest, I let pine needles and leaves pile up on my roof. I make the excuse that I will have time to prepare myself in a real fire. Yet as I consider preparing for “when a fire” is near me, rather than “if”, I feel more of a sense of urgency and responsibility. Second, residents of fire-prone areas should educate themselves about potential ignition sources. Note that fire prone locations are expanding. My parents’ home had not been threatened by fires in their 30 years of living there – until 2020. One resource for determining how to audit a home’s risk is the National Fire Protection Association. Certainly, at a minimum, people should remove flammable materials from or near homes. In addition, they should take into account ignition sources from structures such as decks and ensure that brandons cannot be carried into homes through ventilation ducts or other methods. Placing screens on windows and ventilation ducts, using 1/8 inch holes, can be a simple, inexpensive, and very effective way to keep embers out of a home. Third, act consistently to watch for and eliminate sources of ignition, such as needles or leaves, which can build up gradually over time. Often it takes little effort to remove debris, but it does require constant monitoring and priority removal. [Over 100,000 readers rely on The Conversation’s newsletter to understand the world.

But these measures will save many homes and help reduce risks to firefighters and communities.
