Which statement about the emergency stop is true?

• A. It slows down the machine gradually.
• B. It sounds an alarm but keeps operating.
• C. It halts all functions to prevent injury or damage.
• D. It resets the system automatically.

Answer: (C)

The emergency stop is a safety device designed to bring the machine to a complete stop immediately, cutting off power and halting all functions to prevent injury or damage. Its purpose is to create a safe condition as quickly as possible when a hazard is present, not to slow things down gradually or just trigger an alarm while continuing operation. It also typically remains engaged until someone manually resets the system, rather than resetting automatically, to ensure the hazard has been addressed before resuming.
