What is the term for a person who can identify existing hazards and has the authority to correct them?

The term for a person who can identify existing hazards and has the authority to correct them is "competent person." A competent person is defined by OSHA as someone who is knowledgeable in recognizing hazards in the workplace and has the authority to take corrective measures to eliminate those hazards. This role is crucial because it ensures that safety standards are maintained, preventing accidents and injuries on job sites.

While other roles, such as authorized personnel or a site supervisor, may also have responsibilities related to safety, they do not necessarily have the specific qualifications or authority granted to a competent person. A safety officer typically focuses on monitoring safety compliance and may not have the immediate authority to correct hazards directly but rather reports them. Thus, the definition and responsibilities unique to a competent person make it the correct answer for this question.
