Can an atmospheric diesel storage tank BLEVE? (Video)

I am not 100% convinced this was a “diesel tank”.  Having seen over a dozen diesel tanks explode (most in tests) this explosion looks nothing like it.  It is not a boil-over either, but I am pretty sure the FD would know the difference between LPG tank and a diesel tank.  In what I can…...

What’s the condition of your storage racks?

We have all seen the videos and pics of the storage racks collapsing and most of us are amazed at how violent these incidents are; yet how many of us can walk through our storage areas and not find missing anchor bolts, corroded and damaged structural components, no posted load ratings, or out-of-straight support columns?  In a recent OSHA…...
