It was a static fire, so crew wouldn't be on board anyway. 100% no danger to crew in that case. LAS is likely to be very reliable for ground aborts. Design criteria insist on high (say, 95%) total reliability for LAS. Part of the reason you might want to do such static fires is as a way to trigger (and thus reveal) such problems without endangering crew.
