Snow removal refers to the process of removing snow from an area, typically a sidewalk, street or parking lot. This is done using various methods such as shoveling, plowing, salting or using chemicals to melt the ice. Snow removal is important for safety reasons, as accumulated snow and ice can be hazardous, especially on walkways and roads where people may slip and fall. It also helps to keep traffic flowing smoothly by clearing roadways of snow and ice.
