The arbitrator(s) may decline to begin a hearing or to continue with a hearing or to render an award until the necessary deposits are made. An arbitrator shall notify all parties prior to the hearing if any party's compensation deposit has not been paid or if, during the course of the proceedings, an additional deposit is necessary because it appears that the deposit will not be sufficient to compensate for the time necessary to complete the arbitration.
