Hot work is work that can produce flames, sparks or a source of ignition — such as welding or grinding. The Coast Guard said Friday that a torch was in use at the time of the accident. Grand Isle Shipyard Inc., a subcontractor that was doing maintenance on the platform, has said a welding torch was not in use at the time of the accident.
Other steps outlined by BSEE include keeping the site of Friday's fire shut down, along with other Black Elk facilities where operations have been stopped, or "shut in." BSEE estimated that 41 Black Elk sites are shut in for various reasons.
Friday's accident was on a production platform in shallow water off Louisiana's coast, but it was not producing oil at the time and did not result in a continuous leak of oil, unlike the 2010 Deepwater Horizon disaster.
