Nine workers were killed and several others injured after hydrogen sulfide gas accumulated in a ballast tank of the former 138,000-m³ LNG carrier HL Ras Laffan (now Rasi, IMO 9176008) during dismantling at the Ferdous Steel yard in Sitakunda, Bangladesh. The Department of Explosives said the H₂S built up in a ballast area, not an LNG cargo tank, and measured 10.8 ppm about four hours after the incident on August 15, with officials suspecting concentrations may have exceeded 100 ppm at the time of exposure. The Ferdous Steel was ordered to suspend operations pending a safety audit.
