      This is OK for some systems, but not for emergency broadcasts. No delay is permissible; seconds can mean lives when dealing with a real disaster. The solution, as with so many other things, is proper training for the operations team.

      I think a "are you sure" delay (of about, what, half a second or two?) is not only permissible but required. False positives do damage too.

      A few seconds may be an acceptable delay, but this definitely has to be implemented in a way that ensures that a warning is issued if the operator walks away without confirming. /1

      If true that someone in HI pressed the wrong button, safety covers would also reduce the risk of inadvertently issuing a warning. /2

      I interpreted "button" here as to mean on a computer screen (I don't think it's an actual button). The description of the HI officials makes it sound like there is a checkbox or radio button difference between a test and a live alert — poor design.

          I suspect that you are correct. Though, in my opinion, old-school tactile controls are better for this sort of thing. The act of pressing the button or flipping the switch requires an extra mental step that GUIs no longer require. /1

          People are so accustomed these days, to receiving a high volume of confirmation dialogs and popup messages, that clicking through without reading the message text is a real issue. /2
