to the best of my knowledge the news have misconstrued what happened, the machine that failed was a test high pressure unit developed by a company called Elmhurst research, and has no relation with the industrial units utilized to do things like guacamole, juices, dips etc. As matter of fact the person who died in the accident was the CEO itself.
It is very likely that this unit may not have had enough safety systems such as the “leak before burst” needed for this type of units. I have been involved in HPP systems for over 15 years. And the industrial units are indeed safe to operate.
