They are calling it a “mechanical failure” The guy who was killed was working from a boom truck off the ground. The boom truck and the guy were knocked over and his employee did CPR on him until paramedics showed up...
We have all been making assumptions based on incomplete and inaccurate info. The tank was already cut open and they were attempting to weld a bung in to tie it to the other tanks. So somehow it does sound like there were flammable gasses involved. And not over-pressurization as I had previously speculated this morning.
If the flammable gas was lighter than air how did it form a mixture that could be ignited? have been standing by at the edge of a trench while workers repaired the leak in a natural gas main that sounded like a jet engine. The workers were not very concerned about ignition because the mixture in the hole was out of the flammable range. This was more of a freak occurrence than most people here seem to believe.
