The "lockout" part of the lockout/tagout rule essentially means what?

1. A lockout device is added to ensure the system stays disconnected

2. A tagout device is added to ensure the system stays disconnected

3. A lockout device is installed to disconnect an energy-using device

4. A tagout device must be placed if the energy-isolating device cannot be locked out

The correct answer is: A lockout device is added to ensure the system stays disconnected

The "lockout" part of the lockout/tagout rule is specifically focused on ensuring that machinery or equipment remains inoperable during maintenance or servicing tasks. This is achieved by using a lockout device that is physically placed on the energy-isolating device, preventing it from being operated or re-energized. By locking the device, workers can ensure that the energy source cannot be accidentally activated, which safeguards against potential injuries. In this context, the primary purpose of the lockout is to provide a reliable means of controlling hazardous energy while work is being performed, making it a crucial aspect of workplace safety protocols. This highlights the significance of using proper lockout devices to achieve a secure and safe working environment, thereby emphasizing the importance of physical containment of energy sources during maintenance activities.
