Every employer of 11 or more full- or part-time employees must keep written health and safety records for how many years?

• A. 3 years
• B. 4 years
• C. 5 years
• D. 6 years

Answer: (C)

The key idea is how long a business must keep health and safety records. For employers with 11 or more employees, the rule is to retain those written records for five years. This duration provides a long enough window to identify trends in injuries and illnesses, evaluate safety practices, and be prepared for inspections. The required records typically include the injury and illness logs and summaries that OSHA uses, and the five-year retention applies to all of them.
