Why couldn't you just have the color scheme on the web page invert if you click one of the unusual, dangerous live alerts, so you're immediately very clear that you've selected a non-normal action? So: -- Business as usual -- 1. Click test alert 2. Confirmation appears. -- Nuclear attack or accidental click -- 1a. Click live alert 2a. Invert colors 3a. Confirmation appears. Doable entirely client-side, no need for extensive server-side changes which all these redesign ideas require. And the fact that the webpage background just turned black is clue that you've done something out of the ordinary, especially at shift change (so you don't just blindly hit the confirmation).
