RedactedNarrative: On Saturday August 13th 2022 at approximately 1730hrs operator got on his PWC at Elm Hill Marina in an attempt to start it after it had been fueled up by a dockhand at Elm Hill Marina. The PWC was engulfed in flames and Operator jumped into the water. Another dockhand got a fire extinguisher to put out the fire and subsequently sprayed Operator as well. Operator did not receive medical attention in that moment. He told me that he took himself to medical care and had burns on his face and arms. We were notified on August 30th 2022.  The operator had not vented previously.
