The Importance of Locking-Out, Tagging-Out Procedure for Safety in Engineering and Industrial Sectors

What does the term 'Locking-out, tagging-out' refer to?

A. Applying locks to the power source after de-energizing

B. Tagging deactivated controls and power sources to indicate they should not be used

C. Tagging de-energized equipment and circuits at all points where they could be energized

D. All of the above

Answer:

The 'Locking-out, Tagging-out' procedure refers to the practice of applying locks to the power source after de-energizing it, tagging deactivated controls and power sources to indicate they shouldn't be used, and tagging de-energized equipment and circuits at all points where they can potentially be energized. The correct answer is option D) All of the above.

Locking-out, tagging-out is a safety procedure commonly used in the engineering and industrial sectors. The practices mentioned in the options all fall under this safety procedure. First, applying locks to the power source after de-energizing it serves to prevent the accidental re-activation of a machine or equipment while it's being repaired or maintained. Secondly, tagging deactivated controls and power sources serves as a visual signal to others in the area that these mechanisms should not be used or activated until the tag is removed by the authorized personnel. Lastly, tagging de-energized equipment and circuits at all points where they could potentially be energized is a further preventive measure to protect workers from accidental injury due to unexpected energization or startup of machines or equipment.

So, the correct answer to this question would be 'All of the above'.
