No the feed is not 30 min behind. "Fire Alarm" is the Main Dispatcher. What you are hearing is multiple calls going on in the city and county. They use a computer generated voice for dispatch. It takes a while to get use to the computerized voice. "Command" is the on scene person. The fire units on scene are staging right now as of 12:49am Mobile, Alabama, They are watching it burn. They are hoping it burns out and they don't have any more explosions. I'm sure they will get closer in the morning when they have light.
