COVID Policies During Training Classes:

Yaskawa America, Technical Training Services follows the Center for Disease Control’s (CDC’s) recommendation of social distancing at least six feet during factory training classes held at the Yaskawa America facility in Waukegan, IL. To meet these recommendations, we’ve physically rearranged the classrooms and limited the number of students enrolled in the class.

Students and instructors must adhere to Yaskawa's safety protocol for mask or face shield utilization in all Yaskawa training facilities, which follow local, state or federal mask orders or revised CDC guidelines. Students should bring with them and may wear during the class, a facemask or face shield approved by the CDC for COVID-19 face protection based on Yaskawa’s safety protocol level at the time of their scheduled class.


Yaskawa TTS provides a number of training classes for its customers that require the use of low-level voltages (120vac, 208vac, and 460vac). To ensure a level of safety for the student while working with training class equipment using these voltages, TTS follows an Arch Flash Policy that is consistent with NFPA 70E.

Each student attending the class must wear non-melting, untreated, natural fiber long pants.
