accidentally set off fire alarms

hey so today at work, i was coding up a new app for our client's inventory system, trying to figure out how to make it more user-friendly. i had this great idea of adding sound effects for notifications but ended up setting off an actual fire alarm because the notification audio file sounded exactly like one! everyone rushed out and here i am laughing about my dumb mistake while they're all confused on why there's no fire... oh man, was i embarrassed.
