In imaging rooms, the danger is not so much from broken tools or missing gear. It is compounded by little fissures in the way people think and work under pressure. Too far down is the leaden screen. The apron comes late, as the room has a rushed feel. The moments are shaped more by training and layout than by written rules ever could be. When teams have that insight into how movement, timing, and positioning affect the day-to-day grind, defense can begin to feel pragmatic rather than technical.
