Students must complete a minimum of 8 hours of study time in order to satisfy the 8
hour HAZWOPER re-certification requirement. Along the way there are self grading quizzes, interactive exercises, full length videos and a self grading final exam. The quizzes can be taken as many times as needed, and the final exam can be taken a maximum of 3 times.
Once a person satisfactorily completes the course, an e-certificate .pdf is immediately available to save and print.
NOTE: All students who are taking a refresher course MUST provide copies of their latest certificates prior to payment.
