Abstract:

During welding operations at the E-Complex in support of the Full-Volume RP Construction Project at Stennis Space Center, a fire occurred as a result of welding/cutting operations being performed on Level 5 of the E-1 Test Stand. The Mishap Investigation Team concluded that the proximate cause of this Type C incident was hot welding slag igniting combustible material under and near the vicinity of the welding/cutting operation. Contractor failure to follow procedures associated with hot work permits due to schedule pressure contributed to the incident, as well as lack of training and overburdened supervisory personnel.
