Aerial apparatus refers to equipment used in firefighting and rescue operations that can reach elevated areas. This includes devices like ladders, platforms, and aerial trucks, which allow firefighters to access buildings or structures that are difficult to reach from the ground. These tools are essential for saving lives and controlling fires in high-rise buildings. The use of aerial apparatus is crucial in urban environments where tall structures are common. Fire departments often train personnel to operate these machines safely and effectively. Aerial apparatus can also be used in other emergencies, such as search and rescue missions, where access to hard-to-reach locations is necessary.
