Anti-icing is a proactive method used to prevent the formation of ice on surfaces, particularly in cold weather conditions. This technique involves applying a chemical agent, often a type of de-icing fluid, to surfaces like roads, runways, and bridges before ice can form. By creating a barrier, anti-icing helps maintain safer travel conditions and reduces the need for extensive snow removal. The primary goal of anti-icing is to minimize the accumulation of ice and snow, which can lead to hazardous situations. Common materials used in anti-icing include salt, calcium chloride, and other environmentally friendly alternatives. These substances work by lowering the freezing point of water, making it harder for ice to bond to surfaces.
