How long is OSHA 20 hour good?

The OSHA 20-hour training course, specifically the OSHA 10-hour and 30-hour courses, does not have an expiration date, but it is recommended that workers refresh their training every 3 to 5 years to stay updated on safety practices and regulations. Employers may also require re-certification based on their specific workplace needs or changes in safety standards. It's essential to check with local regulations or employer policies for specific requirements.
