Q – I get timed out when I go to the course, even though I just signed in.
A – In this case, you are actually not timed out at all. If you are using a modern web browser, odds are it automatically blocks pop-ups. Since our course pops up in a new window, your web browser may sometimes interpret this as a page to block when it shouldn’t. There are some solutions that you can do to fix this:

  1. Configure your browser to allow pop-ups for hazwopertraining.otsystems.net, the website our courses are displayed from.
  2. Hold down the CTRL key before you click on a link to temporarily disable the pop-up blocker.
  3. Simply disable the pop-up blocker.

Q – I receive an error when trying to print my completion certificate.
A – Make sure that the latest version of Adobe Reader or Adobe Acrobat Professional is installed on your machine. Our certificates are encoded for security purposes, and require at least Adobe Reader 7.0. If you are using a version of Adobe Reader or Adobe Acrobat Professional that is below version 7.0, then please download the latest version of Adobe Reader or upgrade Adobe Acrobat Professional. The latest version of Adobe Reader and Adobe Acrobat Professional, as of January, 2012, is version 10.

Once the latest version of Adobe Reader has been installed, please log back into the system and try to print your certificate again. If you are still experiencing problems printing certificates through the web, please contact our support desk via email at [email protected] or telephone at 1-800-680-3789. Our support team will try to assist you in printing off a certificate.

Q – I entered my credit card information and proceeded to pay but the screen went blank.
A – In rare cases, some users receive a blank screen after they click “Continue to secure payment” on the payment form. If the URL in the browser starts with “https://secure.linkpt.net” then your payment has most likely gone through. If this is the case, then please contact our support desk via email at [email protected] or telephone at 1-800-680-3789 and we will activate your course manually. Please do not go back and pay for the course again because it might cause the same situation.

If your page does not start with “https://secure.linkpt.net” then your session variables may have expired. Please login again and try to pay for the course again. If, again, this does not work, then please contact our support desk.

Q – I stepped away from my computer for an extended period of time and now I receive errors when I click on any of the student links.
A – Our system has a session timeout of 90 minutes. What this means is that the system will automatically end your visit to HAZWOPERTraining.com after 90 minutes of being inactive. To fix this issue, a user must go back to the student login and re-enter their username and password. Please note that if you were in the middle of a test or section, then, upon relogging in, you will need to redo that section or test. The 90-minute session expiration time is not a time limit allowed on the site at one time, but it is necessary for keeping the site less congested by logging out the people who have been idle for an extended period of time.
