What does LOCKOUT TAGOUT (LOTO) ensure during CNC machine maintenance?

• A. That all tools are cleaned and organized
• B. That machines are properly shut off and not able to be started
• C. That employees have received training on safety procedures
• D. That the CNC machine has been calibrated prior to maintenance

Answer: (B)

LOCKOUT TAGOUT (LOTO) is a critical safety procedure used to ensure that machines are properly shut off and cannot be started while maintenance or servicing is being performed. This process involves physically isolating the machine from its energy sources and locking it out, which significantly reduces the risk of accidental startup that could lead to severe injuries. The effectiveness of LOTO lies in its systematic approach to control hazardous energy. When maintenance personnel follow these protocols, they not only identify and shut down energy sources appropriately but also attach tags that provide clear warnings to prevent others from inadvertently reactivating the equipment. While aspects like cleanliness, employee training, and calibration are important for overall safety and machine operation, they do not specifically address the immediate risk of accidental machine start-up during maintenance. Thus, ensuring that machines are properly shut off and unable to be started is the primary purpose of LOTO, making it the correct answer.
