Are you updating your Outreach Trainer Authorization at a different Authorized Training Organization? (ATO)
OSHA's "January 2019 Program Requirements" regarding changes to an Outreach Trainer's ATO states the following:
Upon changing ATOs, and while a previous trainer authorization has not yet expired, Outreach Trainers are required to notify the original ATO of their new trainer authorization through a different ATO. This will ensure that trainers remain authorized through only one ATO per industry at a time.
