OSHA requirements state that all outreach trainers get reauthorized every 4 years. The ITF is offering two classes this year for those who need to reauthorize. The new OSHA requirements no longer allow a ninety (90) day grace period. If your current OSHA 502 card expires you will need to retake the OSHA 500. If it’s been longer than 7 years since you took the OSHA 510 or you have never taken the OSHA 510 you will then need to retake both the OSHA 510 or 500.
