The state of North Carolina requires some degree of training before persons can use the inflatables on the Outreach Trailers. At least one trained person must be with the inflatables at all times. It is mandatory that at least 2 people from each church view the online training. The people who complete the training must sign a document agreeing that they have viewed all of the training videos (see below). Training must be done within the year the outreach trailer is used and must be repeated each year.
