The "Good Faith" Effort
If OSHA inspects you in December 2026, they will look for evidence of transition. If you are still using a 2012-era program, you will be cited. If you can show a completed audit and a training log from September 2026 covering the changes, you demonstrate "Good Faith" compliance.
