After filing hazmat incident records, how long must they be secured and maintained beyond an employee's tenure?

• A. 30
• B. 5
• C. 10
• D. 20

Answer: (A)

Records of hazmat incidents are kept for a long time to protect worker health and support future investigations. After these records are filed, they must be secured and maintained for 30 years beyond an employee’s tenure. Health effects from hazardous exposure can take many years to show up, and having complete exposure and incident data available for decades helps with medical follow-up, workers’ compensation considerations, and any future regulatory or legal review. Keeping them only for a short period would risk losing important information needed for long-term health and accountability.
