What occurs in step four of the lockout/tagout order?

In the lockout/tagout procedure, step four involves the application of lockout or tagout devices. This step is crucial because it physically secures the energy isolating devices in a position that prevents the accidental start-up or the release of hazardous energy while maintenance or servicing activities are conducted. By applying these devices, authorized personnel ensure that equipment cannot be accidentally energized or operated until the maintenance or service work is finished and they have removed the devices.

The application of lockout/tagout devices also communicates to all employees that the equipment is not operational and should not be accessed, thus significantly enhancing workplace safety. This step comes after the machine or equipment has been shut down and verified to be isolated, allowing workers to effectively manage hazards related to stored energy. Following this step, workers can proceed with their safety-related tasks, knowing that proper precautions are firmly in place.
