A hot liquid sulphur splashed in the
surrounding area as a maintenance technician opened a filter cover on a live
line. Fortunately, no injuries happened.
Operations raised notification to clean the filter in the molten sulphur line. A work permit was raised by maintenance personnel. Shift Supervisor approved the permit without asking the field operator to isolate the equipment. Field operator also signed the hard copy of the permit without isolating the equipment. However, the field operator told the maintenance foreman that the line is not yet isolated and it would be isolated when he was ready to carry out the job. The maintenance foreman gave the permit to the technician but forgot to tell him that it was still live. The technician opened the drain blind flange and opened the drain valve. On finding nothing coming out, he opened the filter cover. Since the line was not isolated hot liquid sulphur sprayed all over the area. Fortunately nobody was injured.
