How long are medical records & HazCom records required to be retained?

• A. 5 years
• B. 30 years
• C. The duration of employment plus 30 years
• D. Indefinitely

Answer: (C)

Long-term retention of medical and HazCom exposure records is required to cover the entire period of employment plus a long tail after the employee leaves. Keeping these records for the duration of employment plus 30 years ensures that any health effects or exposure history that may not become evident until many years later can be reviewed for medical care, workers’ compensation, or regulatory needs. This 30-year tail helps protect employees who might develop occupational illnesses long after they’ve stopped working, and it provides a complete record of exposure and medical information for future investigations. Note that HazCom training records have their own separate requirement (often five years), but the standard practice for medical records and HazCom-related exposure/medical surveillance records is the duration of employment plus 30 years.
