Mass Notification Pre-Recorded Messages For A Museum?

Does anyone have a template they use for the standard pre-recorded messages on a mass notification system? The list I have does not seem appropriate for a building with lots of visitors and untrained people. If you have something that covers some or all of these, you would be my new best friend:

Severe Thunderstorm


Bomb Threat

Active Shooter

Extreme Wind / High Wind

General Evacuation

General Lockdown

If you have any others that you think would be beneficial please share! I am running out of time and patience with these folks, so if you can help me with the scripts for these it would be a HUGE help.
