I'm not quite sure that we have enough essential equipment for our users to "hide in cupboards", and I think on the whole they are professional and responsible enough not to cinsider that as an option.
Revenue is bid for and generally committed when equipment is purchsed. On advice from myself, the relevant clinical budgets receive this. This makes them focus on their equipment management service, and take an active role. It's not just something that happens. "Major disasters" are always dealt with in consultation with the equipment owner, finance and ourselves.
Your comment on needing "amunition" makes it sound like you are fighting a war with your users, we have made allies of ours.
