A person who is capable of identifying existing and predictable hazards and who has the authority to take prompt corrective measures is a __________ person.

The term that best fits the description provided is "competent." A competent person is defined as someone who has the necessary skills, knowledge, and experience to recognize existing and predictable hazards in a particular environment or the job site. This individual is also vested with the authority to take immediate corrective actions to address those hazards, ensuring safety and compliance with relevant regulations.

This role is critical in maintaining a safe workplace, as a competent person can proactively manage risks by identifying potential dangers and implementing proper safety measures before accidents occur. The focus is not only on their ability to identify risks but also on their responsibility to act effectively to mitigate those risks. This dual capacity makes the concept of a competent person vital in occupational safety and health frameworks, including the guidelines set by organizations such as OSHA.

While experienced, designated, and authorized individuals may possess certain qualities or responsibilities, they do not necessarily encompass the complete definition that combines hazard identification and the authority to take corrective measures like a competent person does.
