What is one important consideration when tagging out equipment?

Tags must be visible and readable to ensure that all workers can see and understand that a piece of equipment is locked out and should not be used. This visibility serves as a crucial safety measure, alerting personnel that maintenance or servicing is taking place, which helps to prevent accidental energization of the equipment. Tags that are clear and easy to read communicate vital information about the lockout status effectively, minimizing the risk of confusion or oversight.

The other choices do not prioritize essential safety features. Tags do not need to be expensive; their purpose is to convey specific information, not to incur high costs. Removable and hidden tags could lead to a dangerous situation where the status of equipment is unclear. Colorful or decorative tags might draw attention but do not necessarily provide the important information needed, as the key aspect is clarity and readability.
