An emergency stop button, or E‑Stop, is a fail‑safe control device designed to immediately halt machinery in the event of a hazard. Its purpose is to stop equipment quickly whenever there is a risk of injury, equipment damage, or when a process must be interrupted for safety reasons.
All machinery requires clearly visible, easily accessible emergency stop buttons to reduce risk across industrial, commercial, and public environments. They are typically red with a yellow background, ensuring they can be identified instantly by anyone required to operate them. Complex machinery may feature multiple E‑Stops located at strategic points to ensure any section of the equipment can be quickly brought to a safe stop.
