You Can Take the Refresher Course Online, But OSHA Does Not Recommend Any Provider

OSHA does not recommend, approve, certify, or endorse individual trainers or training programs. It is OSHA’s policy that use of computer-based training by itself would not be sufficient to meet the intent of the standard’s various training requirements. There are two primary considerations for you to explore before deciding whether to take an on-line HAZWOPER course.

  • For HAZWOPER training, it is essential that the trainees have hands-on experience and exercises that provide an opportunity to become familiar with equipment and safe practices in a non-hazardous setting. The purpose of hands-on training (e.g., donning and doffing of protective equipment, using air monitoring equipment) is two-fold: first, to ensure that workers have an opportunity to learn by practical experience and second, to assess whether workers have mastered the necessary skills. Employers need to know how an on-line course provides this hands-on training.
  • Also, in an effective training program, it is critical that trainees have the opportunity to ask questions where material is unfamiliar to them. Providing access to a telephone hotline or an e-mail contact at the time of the training so that trainees will have direct access to a qualified trainer at the time their questions are raised is one way a computer-based training program may accomplish this requirement.
