Flagger Training and Certification

Special Message about Flagger training (updated 4/21/2021):

Although UNH T2 public in-person workshops are currently on hold as a result of the pandemic, the safety and well-being of everyone in public works remains our priority.  We understand you may need to access Flagger  training immediately, and are providing the below list of online training webinars and resources for your convenience.  Most of these are free for local road agency access!  Note that except for the ATSSA course, these are not “certification” courses, and we appreciate that there is value in attending an in-person training.  However, we are available remotely and happy to connect with individuals, teams, or public works colleagues through the phone, Zoom, or other methods to share learning, training, or other technical assistance.  We may also be able to coordinate small team Flagger Certification training.  Please let us know how we can help!

Why consider ATSSA Flagger Certification?

NHDOT 2016 Standard Specifications for Road and Bridge Construction Section 618 3.3 states “Flaggers.  All flagging personnel shall be trained by a designated trainer at least once every four years.  The course shall cover the topics outlined under 3.2.1.  Each flagger shall receive from the designated trainer, a card or certificate that provides the date of training and the designated trainer’s name.  Upon request by the Engineer, the Contractor and its Subcontractors shall provide verification of training within 48 hours.  Any flagger who is trained by a designated trainer and changes employer, must be retrained by the new employer.  Flaggers may elect to take a designated trainer course to meet the training requirements in this section, which would not expire with a change of employers.”

Hosting a Flagger workshop?

The UNH T2 instructor will bring all materials, a projector, a projector screen, and laptop.  The town will need to provide a table to setup the A/V equipment on and an electrical outlet.  The classroom “theory” portion of the workshop is completed indoors, and the practical can be done indoors or outdoors depending on the facility space or weather.  If you have any questions about the suitability of your municipality's space for the Flagger class, please let us know.
