Isn't this where the SLS srbs are stored and the Vulcan solid boosters are built?

@Tory (yes I know you're not exactly reading this)

I'm glad nobody was hurt and your assets were not affected, perhaps you can tell us how this explosion affects your confidence in existing SRBs in your inventory? Does this affect your plans in any way? Any clues as to what exploded and how/why?

Not unusual to have occasional failures. Not sure the building number and the stage of the test campaign when the failure occurred. At least the incident wasn't a PEPCON sized disaster caused by US government storage decisions following the Challenger launch failure:
