Good points and prototype design. Things of such importance should be designed to help remove as much human error as possible. For example, the big red button in modern data centers, they are purposely behind a somewhat weighted glass or plastic casing with clear instructions on it's purpose that has to be manually opened and lifted in order to be pushed. It is a button that cannot be accidentally pushed, unless there is no casing which would be a major design, engineering, management and implementation flaw just waiting to accidentally be pushed. There should be extremely high standards of ease of use and good UX/UI any emergency system, it should remove the capability of accidentally being engaged in a live environment that goes out to the public. If that system is engaged then there should be no doubt it is a true emergency and the individual or individuals operating the system engaged it on purpose. For testing, there should be a clear and informational way to know the system is in testing mode versus production mode. Many experienced engineers have seen what happens when test and production are not separated properly (junior engineer wipes out or causes a disruption in production by properly following a documented process that should have been updated to insure that production, test, staging and dev cannot talk/hurt each other). It is good that this large issue is being addressed, and I hope the entire government takes steps to improve interface design to the emergency systems as when they are needed it should be extremely simple for the operator to insure they are not making any mistakes and should be very difficult for an accident to occur.
