Abstract: On January 30, 2012 Employee #1, a Sand-blast Pot Tender of V.T. Halter Marine Inc., was struck in the head and face by the cast-iron lid from the pressurized black beauty sand pot he was attempting to open. He did not open the pressure-relief valve and turn off plant air going to the 125 psi-rated pressure vessel. Employee #1 was attempting to prepare the pot so more sand could be added. Employees were using black beauty to sand-blast parts. Employees were getting set-up to begin blasting for the morning from the East sand-blast pot. As Pot Tender, Employee #1 climbed the pot's fixed ladder in order to open the lid and refill the pot, a task he had performed many times in the past. Employee #1 failed to depressurize the pressure vessel before opening the lid, causing the accident resulting in the death.
