Step-by-step explanation:
When determining when to wear safety vests and headsets, the best practice is to follow workplace safety protocols and guidelines.

It is important to avoid unnecessary risks by wearing the proper safety gear.

If safety gear is required by your employer or the nature of the task, make sure to adhere to all safety protocol diligently.
