hätäkatkaisua

Hätäkatkaisu, also known as emergency stop or E-stop, refers to a safety function on machinery and equipment designed to prevent injury or damage by immediately halting all machine operations. This function is typically activated by a prominently located, easily accessible button, often colored red and mushroom-shaped, which requires a deliberate action to engage, such as pushing or twisting.

The purpose of an hätäkatkaisu is to provide a rapid and reliable means of stopping a machine in situations where a hazard arises. This can include situations where a person is in danger of being caught in moving parts, where a malfunction occurs that could lead to damage, or in response to any other emergency. Upon activation, the hätäkatkaisu system overrides normal control functions and brings the machine to a complete and immediate stop.

The design and implementation of hätäkatkaisu systems are subject to various safety standards and regulations, which dictate aspects such as the placement of controls, the reliability of the stopping mechanism, and the procedures for resetting the system after an emergency stop has been activated. Resetting an hätäkatkaisu typically requires a specific sequence of actions to ensure that the hazard has been cleared before the machine can be restarted. This prevents accidental re-operation and ensures that the cause of the emergency stop is addressed.
