Which technique can help control a fire from spreading to nearby structures?

Creating a firebreak or using water curtains is a highly effective technique for controlling a fire's spread to nearby structures. A firebreak involves removing vegetation and any other combustible materials in a designated area to create a barrier that fire cannot cross. This method is particularly useful in wildland firefighting but can also be applied in urban settings to minimize the risk to structures.

On the other hand, water curtains involve deploying a continuous stream of water that creates a barrier of vapor or mist, helping to cool the air and reduce the chance of fire spreading. This technique can protect structures by creating a humid environment that inhibits the combustion process.

Both methods aim to separate the fire from potential fuel sources, which is crucial in preventing further damage and protecting valuable assets. These techniques are proactive measures that can effectively mitigate fire spread before it reaches other structures, making them essential tools in firefighting operations.
