16 Hour HAZWOPER Upgrade (Spanish)

Upgrade to the 40 Hour HAZWOPER level online.


Who Should Take This Course?

This OSHA 16 Hour HAZWOPER Upgrade Online course is for workers with 24 Hour HAZWOPER training who wish to upgrade to the 40 Hour HAZWOPER training level. This version of the course provides training that is entirely online.

If students have taken the 24 Hour HAZWOPER from another training provider, appropriate documentation must be provided before a 40 Hour HAZWOPER certificate is issued.

Most students select the online option for their 16 Hour HAZWOPER upgrade to the 40 Hour HAZWOPER level because they still require site-specific equipment training after they complete the course. Due the wide variety of equipment available, the equipment used in a hands-on training session may not be the same as the equipment used at your work site.

Students who should take this course entirely online are workers who a) will use HAZWOPER equipment and receive follow-up training in the use of site-specific equipment from their employer; or b) require an OSHA 40 Hour HAZWOPER certificate but are unlikely to use any HAZWOPER equipment on any worksite.

It should be noted that the online version does not allow students the practical experience and ability to handle the tools and equipment available to the HAZWOPER worker.


The objectives for this course are to meet the Federal OSHA HAZWOPER training requirements of 29 CFR 1910.120(e)(3)(iv) for General Industry and 29 CFR 1926.65(e)(3)(iv) for Construction. This course is also intended to meet any HAZWOPER training requirements for EPA and State OSHA regulations.

29 CFR 1910.120(e)(3)(iv) and 2910.65(e)(3)(iv)

Workers with 24 hours of training who are covered by paragraphs (e)(3)(ii) and (e)(3)(iii) of this section, and who become general site workers or who are required to wear respirators, shall have the additional 16 hours and two days of training necessary to total the training specified in paragraph (e)(3)(i) of the HAZWOPER Regulation.

Course Conclusion 34 16 Hour HAZWOPER Upgrade Summary and Conclusion


This course has 3 exams based upon the course’s first 3 modules. Students are required to complete the exam after completing all course sections. There is no final exam.

Each exam consists of 10 questions randomly selected from a large pool of questions. A 70% score or better is required to pass each exam.

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

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.

If there comes a time that a worker who has taken the OSHA 40 Hour HAZWOPER course entirely online may be required to use any of the equipment discussed during their training, more training may be warranted.

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 – How much time do I have after completing the 24 Hour HAZWOPER training before I must upgrade to the 40 Hour HAZWOPER level?
A – There is no specified time limit within the OSHA regulation. However, it is important that students have completed yearly refresher training sessions.

Q – Can I really take the 16 Hour HAZWOPER Upgrade Online?
A – The 16 Hour HAZWOPER Upgrade Course can be taken entirely online, but keep in mind that students will need to be trained on how to use any protective equipment that they need as part of their job prior to using that equipment on any worksite. This is the case whether the student takes the course online or takes the course in a classroom setting.

Q – In reference to the requirement for employees to have "a minimum of three days actual field experience under the direct supervision of a trained experienced supervisor", per the HAZWOPER regulation, can I do my hands-on training during that time?
A – The three-day requirement of direct supervision has nothing to do with the training requirement. This requirement is meant to ensure that newly trained employees are not sent to a work site and left unsupervised but get supervised field experience for at least three days. It is not part of their training period; it is part of their job function period.

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.
