Aside from the apparent DHS violations, there are questions about procedures that lead to the initial fire and the use of water on ammonia nitrate.
But the most critical point that really needs to be drummed out there is: Sometimes bad things happen. Having watched local streaming the night of the explosion, I couldn’t do anything but applaud the incredibly well executed response to a mass casualty incident.
Texas has long been a leader in examining incidents after they occur, sitting down, figuring out what worked and what didn’t, and then incorporating those results into planning and training. They will absolutely look into (as much as possible) the actions of first responders and come up with recommendations for any updating of training or changing of procedure.
While the feds send multiple agencies to strut and preen, I have every confidence that the state of Texas will learn from the incident, disseminate that learning, and put it into practice the next time something bad happens.
Maybe that will include bulldozing towns or schools or hospitals built next to a chemical plant. But this certainly was a low risk facility with minimal problems over the years.
