In a lockout, what happens to an energy isolating device?

During a lockout, the purpose is to ensure that an energy isolating device—such as a switch, valve, or circuit breaker—is securely locked in the safe or off position. This process is crucial for protecting employees from accidental machine startup or release of stored energy while maintenance or servicing is performed. By locking the device in the off position, it prevents any unforeseen energization that could pose significant safety risks to workers involved in the maintenance activities. This protocol is an essential component of safety standards in the workplace, emphasizing the importance of controlling hazardous energy effectively.
