8 Hour HAZWOPER Supervisor Refresher

Meets the federal OSHA HAZWOPER refresher training requirements for supervisors


Who Should Take This Course?

Workers who have taken the initial HAZWOPER Supervisor Training and need to refresh their HAZWOPER certificate can take the OSHA 8 Hour HAZWOPER Supervisor Refresher. This course refreshes both HAZWOPER Supervisor and 24- and 40-hour HAZWOPER certification.

While this training is different from OSHA 8 Hour HAZWOPER Refresher training, students are not required to take both.

There are currently several versions of this course to choose from, each with a different focus. To see what each version covers, see course Topics.

Again, this Supervisor Refresher course is intended for those students who have already taken the OSHA 8 Hour HAZWOPER Supervisor (Initial) course.

Students with HAZWOPER Supervisor (Initial) training that take this HAZWOPER Supervisor Refresher course do NOT need to take the regular HAZWOPER Refresher course as well. This course will serve as your HAZWOPER Refresher training for the year.


The objectives for this course are to meet the Federal OSHA HAZWOPER training requirements of 29 CFR 1910.120(e)(8), 29 CFR 1910.120(p)(7)(i), or 29 CFR 1910.120(q)(8) for General Industry and 29 CFR 1926.65(e)(8), 29 CFR 1926.65(p)(7)(i), or 29 CFR 1926.65(q)(8) for Construction. This course is also intended to meet any HAZWOPER training requirements for EPA and State OSHA regulations.

Per 29 CFR 1910.120(e)(8) and 29 CFR 1926.65(e)(8)

Employees specified in paragraph (e)(1) of this section, and managers and supervisors specified in paragraph (e)(4) of this section, shall receive eight hours of refresher training annually on the items specified in paragraph (e)(2) and/or (e)(4) of this section, any critique of incidents that have occurred in the past year that can serve as training examples of related work, and other relevant topics.

Per 29 CFR 1910.120(p)(7)(i) and 29 CFR 1926.65(p)(7)(i)

The employer shall develop and implement a training program which is part of the employer's safety and health program, for employees exposed to health hazards or hazardous substances at TSD operations to enable the employees to perform their assigned duties and functions in a safe and healthful manner so as not to endanger themselves or other employees. The initial training shall be for 24 hours and refresher training shall be for eight hours annually. Employees who have received the initial training required by this paragraph shall be given a written certificate attesting that they have successfully completed the necessary training.

Per 29 CFR 1910.120(q)(8) and 29 CFR 1926.65(q)(8)

Those employees who are trained in accordance with paragraph (q)(6) of this section shall receive annual refresher training of sufficient content and duration to maintain their competencies, or shall demonstrate competency in those areas at least yearly.

If a student does not pass an exam the first time, they may retake the exam as many times as necessary in order to pass.

Additional Training

This course is designed to help workers meet the OSHA 8 Hour HAZWOPER Refresher requirements. If this course takes less than 8 hours to complete, it should be combined with other training conducted throughout the year to meet the 8-hour requirement. This additional training can come from hands-on, job- or company-specific training, or even tailgate safety meetings.

Workers must receive additional training, when required by Federal and State OSHA and EPA standards, on the specific hazards of their job.

Training providers should be used to ensure credibility and augment a company's training program. Therefore, in addition to the training provided by an outside party, a student should receive site-specific training that is supplied by their own company. This training should target the company's unique approach to hazard prevention, including the use of site-specific equipment, health and safety policies, and emergency procedures. As a rule, this company specific training should be well documented.

The bottom line in ALL SITUATIONS is that employers are required to ensure that their employees are adequately trained to do their job.

Mobile Version

We’re excited to announce that this course is now available in HTML 5, making it more compatible with the browser on your mobile device (e.g., smartphone or tablet).

Many of our existing courses are presented using Adobe Flash Player and require additional software that may not be available on your mobile device. By comparison, this course requires only the most recent version of your mobile device's web browser.

Mobile Pros & Cons

Mobile versions of this sort of training are new, but below are some Pros and Cons that we have noticed during our extensive testing.


  • No computer needed
  • Tablet mobility
  • Tablet screen graphics


  • Smartphone screens can be too small to see
  • Mobile browsers react differently than computer browsers
  • Phone calls can interrupt training

During our testing we noticed that tablets work much better than smartphones, simply due to their screen size. The newer the device, the better the result. We are also aware that the course will not work on the first generation iPad, nor older Android Tablets.

Growing Pains

Because this is a Beta version of our course, you may encounter some issues as we work out the kinks.

Your Mobile Browser

While HTML5 makes taking this course on mobile devices possible, not all mobile browsers are optimized for HTML5, meaning you may not have complete functionality. If you have difficulty taking this course using the browser on your mobile device, you may need to use a different browser.

Test the functionality of your browser using HTML5 and compare it to the performance of other browsers. If you find other browsers are more compatible than your own, you may want to make the switch.


Q – Why are there different versions of this class?
A – The multiple course versions are designed with the intention of offering you more options for your training. The more applicable your training can be toward your job, the better.

Q – Are all versions accepted by OSHA?
A – Yes, all versions meet OSHA requirements. OSHA allows flexibility in training and prefers training to be individual specific.

Q – Which version should I take?
A – Pick the material that seems most relevant to you and your job, or that you are most interested in.

Q – Will I receive the same certificate?
A – Yes, the certificate you receive is the same and does not vary depending on which version you choose.

Q – What if it has been longer than 12 months since I received my refresher training?
A – This does not mean you must take the initial training all over again. Per OSHA, “If the date for refresher training has lapsed, the need to repeat the initial training must be determined based on the employee’s familiarity with safety and health procedures used on site. The employee should take the next available refresher training course. There should be a record in the employee’s file indicating why the training has been delayed and when the training will be completed.”

Q – Can I use my one-time 8 Hour Initial HAZWOPER Supervisor training course as my refresher training for that year?
A – No, OSHA would expect a general hazardous waste site worker who is becoming a supervisor or manager to receive at least 16 hours of training during the year they become a supervisor: 8 hours of management and supervisory training in addition to 8 hours of employee refresher training. HAZWOPER requires that supervisors and managers be trained and given supervised field experience to at least the level of the employees who they will oversee, and have at least eight additional hours of specialized training on the topics listed in 1910.120(e)(4).

Q – How long will this course take to complete?
A – Our courses are set up to take a specific amount of time. Some students may get through the training more quickly, while others may actually take longer to complete their training. Remember, this training should be used as an intricate tool in the context of an overall training program; it can be combined with other training throughout the year in order to meet any hour requirements needed.

Q – Do I have to finish the course in one sitting?
A – No, our courses are designed so you can start and stop as needed, allowing you to break the training up over a longer period of time. Our system will keep track of your progress, enabling you to resume where you left off upon your next login. It is important that once you start a section, you complete that section or you will need to start that section over from the beginning upon your return.

Q – Can I take the course from more than one computer?
A – Yes, you can take the online portion by signing in with your username and password from any location and computer with high-speed internet access. However, each computer does need to meet our basic system requirements for viewing our online courses.

Q – Will I receive a certificate for this course?
A – Yes, once you have completed a course, you are able to download, save or print a certificate of completion from your student account. Certificates are created in a PDF format. Users must have the latest version of Adobe Reader before attempting to download the completion certificate.
