Under COR requirements, hazard assessments are retained for as long as the work covered is being done.

• A. 5 years
• B. 1 year
• C. As long as the work covered is being done
• D. Indefinitely

Answer: (C)

Under COR requirements, hazard assessments are tied to the specific work they cover. They document the hazards, the controls, and the steps needed to manage risk for that particular scope. Keeping the assessment for the entire time the work is being done ensures the information stays current and available for planning, implementation, and any investigations related to that work. Once the project ends, the hazards and controls may change with new tasks or site conditions, so retaining these records beyond the completion of the work adds little value and can become outdated. For this reason, the appropriate retention period is as long as the work covered is being done. Fixed periods like five years or one year, or indefinite retention, do not align with the need for current, task-specific risk management.
