OSHA #511 Occupational Safety and Health Standards for General Industry course

What is the first step in the process of Lockout/Tagout (LOTO) to prevent injuries?

1. Block the energy source

2. Dissipate the energy source

3. Isolate the energy source

4. De-energize the energy source

The correct answer is: De-energize the energy source

The first step in the Lockout/Tagout (LOTO) process is to de-energize the energy source. This step is critical because it ensures that all sources of hazardous energy are properly turned off before maintenance or servicing activities begin. By effectively de-energizing, you significantly reduce the risk of accidental energization, which could lead to severe injuries or fatalities. De-energizing involves taking the necessary actions to ensure that the machinery or equipment is no longer capable of releasing energy that could cause harm. This includes shutting down machines and equipment and ensuring that any stored energy, such as hydraulic pressure or electricity, is removed or neutralized, providing a safe working environment for employees. In summary, the de-energization step is foundational to the entire LOTO process as it sets the stage for the subsequent actions required to safely lock and tag out equipment.
