Given the amount of protocol breaks here, "it should be standard practice" is a bit pointless to talk about. "Standard practice" has multiple parts to ensure this never happens even if one step fails, so clearly it was massively ignored here. (And that's something an experienced actor like Baldwin arguably should've noticed as a problem)

(And probably the actual protocol of "armorer handles gun and shows what's being done" is safer if you ever involve blanks than having an untrained actor fiddle with a gun)
