I'm not clear if you're referring to planned high pressure processes or to emergency scenarios that result from explosions. According to Labconco, even explosion proof chemical hoods are not designed to contain explosions
rather their electrical design makes them less likely to spark one.

I don't if I ever seen a hood designed to contain an explosion inside the hood...
