All OSHA 10-Hour classes are to be completed over 2 days. You must attend both Day 1 and Day 2 in order to receive your official OSHA 10-Hour card.
Lost OSHA Cards:
If you lose your OSHA card more than three years after your original training date, OSHA will no longer issue replacement cards. If you lose your official OSHA card within 3 years of the date of taking the class, you will be allowed one (1) replacement card for a fee. (Per OSHA)
