An Emergency Stop Button is a safety device designed to quickly shut down machinery or equipment in case of an emergency. It is typically a large, red button that is easily accessible and can be activated by anyone nearby. The primary purpose is to prevent accidents and injuries by stopping operations immediately. These buttons are commonly found in industrial settings, such as factories and construction sites, as well as in public spaces like elevators and amusement parks. Regular maintenance and testing are essential to ensure that they function correctly when needed, providing a crucial layer of safety for workers and the public.
