A ladder is a tool used to reach high places. It typically consists of two vertical side rails connected by horizontal rungs. Ladders can be made from various materials, including wood, aluminum, and fiberglass. They come in different types, such as step ladders, extension ladders, and folding ladders, each designed for specific tasks and heights. Ladders are commonly used in construction, maintenance, and household tasks. Safety is important when using a ladder, so it is essential to follow guidelines, such as ensuring the ladder is on a stable surface and maintaining three points of contact while climbing. Proper use helps prevent accidents and injuries.
