Every summer at harvest time, fire brigades are alerted with the alarm keyword “Burning grain field / stubble field”, some particularly affected fire brigades in hot summers almost daily.
Some dismiss these kinds of operations as trivialities - but they are not. It is not the material value, which can amount to several thousand euros depending on the size of the field and the type of grain, but the sometimes massive danger to oneself that these fires can pose. Time and again, there have been minor and major accidents while fighting wildfires - with burnt-out fire engines and injured or even killed comrades. Bear one thing in mind: In this type of operation, you are only protecting material assets or, in the case of stubble fires, “only” the environment, i.e. it is irresponsible to endanger the lives and health of your own comrades here. Safety is therefore the top priority for all grain field fires.
So what makes these fires so dangerous? Vegetation fires are significantly influenced by three factors: characteristics of the vegetation, weather and terrain.
