UL EHSS Courseware

HTML5 in eLearning is the new industry standard. It offers a mobile-friendly development method that delivers dynamic content, intuitive navigation, faster loading and increased functionality across multiple browsers, devices and screen sizes. HTML5 eLearning can be accessed anywhere, whenever it’s most convenient for the learner. UL EHSS is excited to now offer PURE Safety LMS version 5 (PS5) courses in HTML5.

HTML5 requires use of modern browsers.  For the following operating systems, these are:


Operating System Browser
Windows 7, 10
  • Microsoft Internet Explorer 11
  • Microsoft Edge
  • Chrome (latest version)
Mac OS 10.9
  • Apple Safari 7 or higher
iPad iOS8
  • Safari 7 or higher
Android 4.4 (KitKat) or higher
  • Chrome (latest version)


For the device playing the content, we recommend a minimum processor speed of 1.5 GHz and RAM of 1 GB. For optimal video playback and loading, we recommend exceeding these minimum requirements.

You should also confirm with your LMS provider that your LMS can support HTML5 content.

The network supporting your LMS will need permission for the following file types:

  • Audio/aac .aac
  • Audio/mp4 .mp4 .m4a
  • Audio/mpeg .mp1 .mp2 .mp3 .mpg .mpeg
  • Audio/ogg .oga .ogg
  • Audio/wav .wav
  • Video/ogg .ogv
  • Video/webm .webm


UL EHSS’ HTML5 courses are not guaranteed to play on smartphones at this time. Tablets and computers typically provide the best learning experience.

UL EHSS courseware is packaged according to AICC or SCORM specifications and is designed to work with the majority of Learning Management Systems (LMSs) that support those standards. Specifically, courseware is packaged in AICC version AGR-010, and SCORM version 1.2 and 2004 v3.
