  1. ADecember 31, 2026
  2. BDecember 31, 2024
  3. CDecember 31, 2028
  4. DDecember 31, 2025
Show answer & explanation

Correct answer: C. December 31, 2028

Cal/OSHA recordkeeping regulations require employers to retain Form 300 logs, Form 301 incident reports, and Form 300A summaries for 5 years following the end of the calendar year the records cover. For records covering 2023, retention must extend through the end of 2028.

Why the other options are wrong

  • A. Three years is still short of the mandated 5-year retention.
  • B. One year of retention is far too short under the 5-year rule.
  • D. Two years does not satisfy the required 5-year retention period.

Cal/OSHA Recordkeeping Retention

Employers must retain Form 300 logs, 300A summaries, and 301 incident reports for 5 years following the end of the calendar year the records cover.

  • Retention period is 5 years, separate from the Form 300A posting period (Feb 1–Apr 30).
  • Applies to employers required to keep OSHA injury/illness records.
  • Records must be made available to employees, former employees, and their representatives upon request.

Memory trick: Five years locked in the file cabinet after the year ends.
