Who Should Take This Course?

Our online HAZMAT Incident Commander Refresher Online (4 Hour) course is designed to help workers who have been previously trained to the On Scene Incident Commander level to meet the OSHA HAZWOPER Refresher requirement in Standard 29 CFR 1910.120(q)(8)(i).

Per 29 CFR 1910.120(q)(8)(i):

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…

For Incident Commanders, OSHA does not specify the minimum duration of required Refresher training, only that it must be of sufficient content and duration to maintain competencies. However, employers often mandate 4 or 8 hours of Incident Commander Refresher training. With this 4 Hour Incident Commander Refresher course, workers can meet OSHA requirements and also company-specific requirements by taking the course annually (4 hours per year) or semi-annually (8 hours per year). Workers often prefer semi-annual training to reduce the length of time in-between course sessions.

This Annual Refresher course includes training on the: Role of an Incident Commander; Features of the Incident Command System; Roles of Command Staff, General Staff and other Positions in the Hazmat Group; Private Facility Response; Hazmat Incident from Start to Finish; and more.
